DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a method of manufacturing a stainless steel coil, and more particularly to a method of manufacturing a new, ultra-thin stainless steel coil. [Prior Art] At present, there are three types of stainless steel coils and their production methods. Referring to Figure 1, the flat steel embryo 100 (slab) is used as a raw material, and after a hot rolling process 11 to a predetermined thickness, a black c steel is obtained, and the black steel steel roll 200 is subjected to an annealing process. After the sand process 13 and the pickling process 14, a white steel coil 3 is obtained (white coi b also referred to as NO. 1 coil). Among them, because the black steel coil 200 has a thickness of rust, it can only be regarded as a semi-finished product, generally not directly processed and applied, and / or provided to _, downstream manufacturers for further processing such as buckets, water towers Stainless steel products such as kitchen utensils; the thickness of the white steel coil 3〇〇 is similar to that of the black steel coil 2,, and the main thickness difference between the two is due to the reduction after the removal of the scale, and the other is because the white steel coil is 3〇〇 After the modification of the annealing process, a few middle and downstream manufacturers will choose the white steel coil 300 as raw material for further processing after considering their own process capability and cost. Therefore, the white steel coil 3 (10) can be regarded as the actual product. One of the coils. Refer to Figure 2 'Because the thickness of the white steel coil 300 is similar to the black steel coil 200, usually there is still a gap between the force and the will of the general middle and downstream manufacturers in the process of 2mm or more. Therefore, there will be a gap. The cold rolling process 21 is carried out with the white steel coil 300 as a raw material to be further thinned to about 2 mm or less, and then the left over annealing process 22 and the pickling process 23 are used to obtain a cold rolled steel coil 400. 5 201006934 】vzh steel coil is also called 2D steel coil, 2 refers to the steel coil through the hot process 11 (ie the process of flat steel (10) into black steel coil 200) and cold luck process 21 (ie white The process of rolling the steel coil 3 into a cold-rolled steel coil 4) "Two" process 'D is the abbreviation of Dull, which means that the surface of the steel coil has no characteristic metal brilliance; and, because of cold-rolled steel The thickness of the roll 400 has been met by the requirements of the general middle and downstream manufacturers for further processing, production and processing, so the cold rolled steel coil 4GG can be regarded as the most important actual product steel coil. Referring to Figure 3, and 'though the thickness of the cold-rolled steel coil 4 has been thinned to about 2 coffee, such thickness is still too thick for direct processing and production of steel products such as buckets and kitchen utensils. Cold-rolled steel is used as raw material '_ to carry out the cold-drying process 31 to be further thinned to a thickness of not more than 0.7, and then the annealing process 32 and the pickling process 33, and/or through the roller-milking process 34' to obtain cold rolling Sheet steel coil 500. Cold-rolled sheet steel coils are classified according to whether the surface is bright or not. The sheet steel is not subjected to the rolling and tempering process 34, the surface ash has no characteristic metal brilliance), the second slab: the coil (after the roller tempering process 34, the surface It has the unique characteristics of the metal. In addition to the direct processing, such as buckets and kettles, hundreds of 6/steps (four) into ultra-thin (industry applications: rust steel pieces for technical applications such as displays), so it is currently the main actual One of the recorded steel coil products - can not simply follow the above description 'by the way of paper work, the order === kind_making method is merged and rewritten into, for example, "smooth rolling, sequential hot rolling, annealing Process, pickling annealing process, pickling process, cold milk process 'annealing system 201006934 process 'and pickling process' to produce cold (four) plate steel coil 5 (8)", or "think steel _ as raw material, in order to pass heat Rolling process, annealing process, pickling process, cold, process, annealing process 'with the pickling process' to obtain cold-rolled steel coils" or white steel coil 300 as raw material, sequentially through the cold rolling process, annealing process, Pickling process, cold rolling process Annealing process, and pickling process, to obtain cold-rolled sheet steel coil 500", and even arbitrarily combine (four) process, cold (four) process, annealing process, and the order of pickling process to make other various types of stainless steel coils Products. ® ^ 'The know-how of the steel technology' special stainless steel coil production knows that the manufacturing methods and products of the steel coils written on these paper operations will be due to, for example, the fundamentals of the process sequence. Infeasible (if it is not possible to carry out the cold rolling process and then heat up the hot rolling process, or go through the 'acid picking process and then the annealing process ··..), or the ability of each part of the equipment itself (such as direct pickling process) Remove the scale, or roll the flat steel sheet into a thin sheet steel semi-finished product with a thickness of less than 0.7mm... or), or combine it into the cost of intervening after the production, or whether it can really The overall coherent production of the specific factors of the special considerations, rather than can be implemented, and therefore, the choice of stainless steel coils that the industry can provide is limited to white steel coil 300, cold rolled steel coil 400 and cold rolled sheet steel coil 500. Also, because the stainless steel coils that can be further processed as raw materials are only white steel coil 300, cold rolled coil 400 and cold rolled sheet coil 500. Large, rolling thickness limits will be subject to the hot-drawing process, usually the minimum thickness that can be achieved after the flat steel embryo 100 is used for hot-rolling process is about 2.0mm. Therefore, the operator wants to use the thickness 7 201006934 in 2.0 When the white steel coil 300 below mm is processed as a raw material, it will be forced to use cold-rolled steel coil 4 as a raw material because there is no suitable raw material selection, and the cold-rolled steel coil 400 is made of a white-rolled steel coil. There are many, so when the unit price is relatively high, and the low-cost high-temperature cold-rolled steel coil 4 is used as raw material for subsequent processing and production, of course, it is not conducive to market competition. In addition, limited by the thickness of the white steel coil 300, if the cold-rolled steel coil is directly produced from the white steel coil 300 as a raw material, since the thickness difference between the two is extremely large, it is necessary to carry out the high rolling rate. The operation is not only low in productivity but also due to severe work hardening, which leads to a problem of high rate of broken tape. Of course, to overcome the problem of work hardening, it is feasible to carry out an annealing, but this will cause an increase in cost. , anti-competition. Therefore, there is a new, strictly speaking, demand for intermediate goods between white-skin steel coils and cold-rolled steel coils. This type of stainless steel coil must meet the unit price of cold-rolled steel. Low, the same: re-rolling and thinning, or the difficulty of further processing operations is easy to white steel = 300; therefore, 'how to make it possible to manufacture such a stainless steel coil 13 method per method' is the current steel industry efforts One of the goals. [Summary of the Invention] The purpose of this umbrella is to provide a non-mineral steel ultra-whitening method for the production of steel coils, to make W + super 4 white skin to produce the stainless steel super white that has long been needed in the market. Steel coil products. The manufacturing method of the ultra-thin white steel coil of the stainless steel of the moon is carried out in the following four steps. 8 201006934 The first step is to use a black steel coil as the incoming steel coil. The second step is to carry out a cold rolling process on the black steel coil to obtain a semi-finished product of cold black steel coil. The second step is to perform an annealing process on the cold-rolled black-skin steel coil semi-finished product to obtain a modified cold-rolled black-skin steel coil semi-finished product. The final step is to perform a sandblasting process and a pickling process on the modified second black-skin steel coil semi-finished product to remove the scale, and obtain the ultra-thin white steel coil of the stainless steel. β The effect of the present invention is to provide a simple and practical method for producing and applying ultra-thin cold-rolled black-steel coils with a minimum thickness of 10 mm through a cold rolling process directly using a black steel coil as a raw material for the feed. After annealing and quenching and tempering, pickling process and sandblasting process to remove the scale, a stainless steel ultra-thin white steel coil can be produced to meet the long-term demand of the market. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of a preferred embodiment of the drawings. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to FIG. 4', a preferred embodiment of the method for manufacturing the stainless steel ultra-thin white steel coil of the present invention is capable of producing a stainless steel ultra-thin white steel coil 6' with a minimum thickness of up to 1.0 mm to meet the market. The need for such stainless steel commercial coils. First, in step 41, the black steel coil 200 is used as the incoming steel coil, and the hot rolling process 401 is prepared for the 201006934. " It is step 42' to carry out the cold rolling of the black steel coil 2 including at least two cold rolling and the rolling rate is not less than the driving, so that the peeling loss is not lower than (4), get - minimum Cold-rolled black-skin steel coil semi-finished product 61 with a thickness of up to 1 coffee. Then, in step 43, the cold-rolled black-skin steel coil semi-finished product is subjected to an annealing process 402 to obtain a cold-rolled black-skin steel coil semi-finished product 62; here, the cold-rolled black-skin steel coil semi-finished product 61 is passed- The temperature is raised in the preheating zone of the thermal heat radiation preheating in the main heating zone of 1 〇〇〇 to 1200 t, and then passed through the main heating zone a 100 (rc~120 (RC high temperature heat treatment modification, finally The annealing process 402 is completed by removing the surface moisture from a cooling zone having a temperature of not more than 8 (rc and removing moisture). Then, step 44 is performed to perform a sandblasting process 403 and acid on the modified cold-rolled black-skin steel coil semi-finished product 62. Washing process 4〇4 to remove the scale gives a good steel ultra-thin white steel coil 6 with a minimum thickness of up to 1.0 mm. It is specifically noted that due to the cold rolling process in step 42 4〇1 During the process, the scale of the black steel coil 200 is largely peeled off due to rolling, so the blasting process 403 performed in this step 44 is only required to rotate the wheel speed below the medium speed 'that is, about 500 rpm to 1000 rpm. The sandblasting equipment can be used to remove the residual scales, and also because of the sandblasting process. 403 is treated at medium and low speeds', so that the obtained stainless steel ultra-thin white steel coil 6 has a fine surface roughness, and also because the skin of the black steel coil 200 is largely peeled off due to rolling, and After the sand blasting process 403, the residual scale is almost completely removed. Therefore, when the pickling process 404 is performed, the concentration of the mixed acid can be lowered to 10 201006934 to effectively increase the production speed. From the above, the stainless steel ultra-thin white steel of the present invention can be known. The method of weaning of the roll 6 is to use the black steel coil 2 as the raw material for the feed, and the black skin coil 200 is subjected to a cold rolling process including two to three passes, and the dry rate is not less than the cold process of the township 401. The ultra-thin (minimum thickness up to 1 〇匪) cold milk black steel coil semi-finished product 61 is obtained, and then the annealing process 402, the sand blasting process 403 and the pickling process 4〇4 are directly performed to modify and remove the ore skin. The stainless steel ultra-thin white steel coil 6 with a minimum thickness of 1 〇mm, which has been used for a long time in the market, is produced, which is further processed and utilized by the middle and downstream industries; and since the black steel coil 200 is in the cold rolling process 4〇 1In progress, the scale has been enlarged due to rolling Peeling off, so the subsequent sandblasting process 4〇3, pickling process 4〇4, etc. can be carried out under the condition of greatly saving equipment cost and consumable cost, and at the same time, because the sandblasting process 403 only needs to be at medium and low speeds. This also makes the stainless steel ultra-thin white steel coil 6 have a fine surface roughness, which is more in line with the market demand. Black steel coils of 200 steel and 200 steel and black steel coils 〇 _ As the incoming steel coil, and the stainless steel ultra-thin white steel coil 6 after the above process is obtained, the corrosion loss of the stainless steel is compared with the '304 steel black leather coil 200 after the cold rolling process 401 The peeling loss rate of the scale is about 3〇%, and the peeling loss of the black skin of the 43〇 steel is about 70%, which really helps the speed of the subsequent sandblasting process 403 and the pickling process 404, especially the mouth sand process. 403 'Because the peeling loss of the scale is high, it is only required to be carried out at medium and low speeds, thus making the stainless steel ultra-thin white steel coil 6 have a fine surface roughness & degree (see Table 2)' with the black skin of Figure 1. Steel coil 200 directly passes through the re-fire process 11 201 006934 12. Compared with the white steel coil 300 obtained by the pickling process 14, the surface roughness of the stainless steel ultra-thin white steel coil 6 obtained by the invention is greatly reduced to 2.02/zm (304 steel type). 1.70/zm (430 steel grade), obviously with extremely fine surface roughness. In particular, the black steel coil 200 of the 430 steel grade is segregated by the high chromium content and is not easily pickled due to its own nature and through the batch annealing (BAF, Batch Annealing Furnace) in the process, but the present invention is black. The steel coil 200 is first cold-rolled two to three times and the cold rolling pass 401 with a rolling reduction of not less than 50% causes the scale to be peeled off a lot, so it is very easy to carry out the subsequent pickling process @ 404 - compared to the conventional white The acid mixing process of the steel coil 300 has a mixed acid concentration of about 50% or less, and the sandblasting process 403 - the conventional white steel coil 300 is a high speed, that is, a sandblasting apparatus higher than 1000 rpm. The present invention is carried out at a medium or low speed of about 500 rpm to 1000 rpm, so that the residual scale can be removed, and the production speed can be effectively increased by about 180% or more (the conventional white steel coil 300 is about 25 meters per minute, the present invention The manufacturing method is produced at a speed of 70 meters per minute, which greatly increases the production speed.

Since the manufacturing method of the sample is to use the cold rolling process of cold rolling process of 4〇1 to 3 passes, the thin black steel coil 200 is thinned, and the black skin coil 200 is recorded in the cold rolling. The process 401 is rolled and peeled off in a large amount, so that the blasting process such as the subsequent blasting process 403 and the pickling process 404 can be carried out under the condition of greatly saving equipment cost and consumable cost, and also because of the rust skin. Rolling and a large amount of peeling off, so the sandblasting process 4〇3 only needs to enter the middle and low speeds, so that the stainless steel ultra-thin white steel coil has a fine surface roughness degree, so that the product steel coil is produced. (ie, the non-key steel ultra-thin white steel coil 6) has the advantages of low unit cost and easy subsequent processing. It does provide a steel coil product that meets the long-term demand of the market and has a very thin thickness and is easy to process. Further, it is further processed and utilized by the middle and downstream industries to achieve the creative purpose of the present invention. The above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change of the scope and the description of the invention according to the invention patent 13 201006934 Modifications are still within the scope of the invention.
