Definitions
- the invention relates to a method for producing strips and sheets of steel with the process steps of casting a strand in thin slab format from a carbon steel or a stainless steel in a casting machine, guiding the cast products through a compensating furnace to achieve a uniform temperature, rolling the cast products in a rolling train, Cooling of the rolled product on an outfeed roller table and winding of the rolled product on a winding device.
- the invention relates to a plant for performing the method.
- thin slabs are understood to mean cast products with a thickness between 30-130, in particular between 40-60 mm.
- EP 0 808 672 A1 discloses a method and a plant for producing stainless steel or carbon steel sheet from thin slabs produced by continuous casting.
- a thin slab strand of 40-100 mm thickness either cast from a stainless steel melt or from a carbon steel melt, is divided into sections, the individual thin slabs are conveyed through a heating line and then rolled continuously.
- the present invention is based on the object of further developing a generic method and a generic system. none that the production of strips and sheets made of stainless steel becomes more economical.
- this object is achieved in that, together with the first cast products produced in a first process route, at least in a second process route, second cast products made of stainless steel, when the first cast products are cast from carbon steel, or from carbon steel, when the first cast products are cast from stainless steel are rolled within a common rolling program.
- the core of the invention is accordingly to integrate products of both steel types in a common rolling mill on a generic plant and to roll them within a common rolling program.
- the term rolling program is generally understood to mean the predetermined sequence of slabs to be rolled in the period between two roll changes.
- an optimal utilization of a plant is achieved, which would not be fully utilized if only stainless steel sheets were produced, which are produced in small quantities compared to carbon steels.
- the greater variability of a plant on which carbon steels are produced is increased by additional rolling of stainless steels.
- the invention is not limited to a rolling program for cast products from the two types of steel; It is also conceivable to roll additional types of steel in a rolling program, but carbon steels and stainless steels are always rolled together. The suggestion of rolling in a joint rolling program makes it possible to process two very different types of steel, regardless of the throughput of a line or the amount of steel produced.
- stainless steel is basically defined in EN 10 020. A distinction is made between unalloyed and alloyed stainless steels.
- the stainless steels according to the invention are, for example, roller bearing steels,
- Tool steels heat-resistant steels and high-grade structural steels.
- This term is used to describe higher-alloy steels with alloy elements and quantities that stabilize the austenite structure at lower temperatures, including in particular the high-alloy austenitic CrNi steels.
- the rolling mill is adapted to the material to be processed during the rolling program.
- This preferably means that the rolling train is already being prepared for the subsequent material to be processed in the rolling program while the previous one is still being processed.
- the negative effects due to the stainless steel rolling on the surfaces of the work rolls which usually have an effect on rough surfaces and which have a disruptive effect on the subsequent rolling of the carbon steels, have already been eliminated in operation or online.
- the negative effects resulting from the carbon steel rolling in the form of a larger amount of loose scale, which would press into the surface of the subsequent stainless steel product, are removed analogously in operation or online when the carbon steels are rolled. In this way, the rolling mill is optimally prepared for the subsequent rolled product.
- the preparation of the rolling train for the respective subsequent strip also takes place during the rolling break between the rolling process of two strips.
- the first cast products in thin slab format or groups of these and the second cast products or groups of second cast products are rolled alternately.
- the term change allows an irregular or regular change between slabs of one and the other type of steel.
- the second cast products rolled together with the thin slabs of the first process route in a rolling program can either be thin slabs themselves or so-called conventionally cast slabs that run into the common rolling mill after pre-rolling.
- thin slabs which are cast and cut in a second, parallel, process route to the first process route, these are preferably fed via a possibly second equalizing furnace and a ferry into a common equalizing furnace and then into the rolling mill.
- conventionally produced slabs i.e. Cast products with casting thicknesses of up to 250 mm are pre-rolled on a conventional hot wide strip mill in the reversing stand.
- the then cooled slabs are reheated from the cold state in a slab furnace after being transported to the installation in which the first process route takes place, and are integrated via a ferry into the compensation furnace of the first process route or the rolling mill in the sequence specified according to the rolling program.
- a pre-rolled slab is transported directly without cooling, so that it can then be integrated into the common rolling program. Homogenization of the temperature before integration is useful.
- This invention is not limited to the described possibilities for the incorporation of thin slabs or conventionally continuously cast pre-rolled slabs; the incorporation of any cast product, for example produced by strip casting, is conceivable, although the preliminary products produced in this way already have small initial thicknesses.
- Stainless steel when the first cast products from the first process line made of carbon lenstahlstahl are cast, or to insert at least second cast products made of carbon steel, if the cast products from the first process line are cast from stainless steel, to equip and with a rolling mill for a combined rolling program for cast products made of carbon steel and stainless steel and preferably with means for preparing the rolling mill for the subsequent rolled product of the other steel grade.
- a grinding and / or polishing device for the work rolls of at least one roll stand is provided for this purpose, which counteracts a rough roll surface during the rolling of the stainless steel products and / or during the pause between rolls.
- These are preferably arranged on all inlet stands, for example in the form of grinding devices which press against a work roll, on all roll stands of the rolling train.
- the rolling mill has a rinsing device which works in particular or to a greater extent during the rolling of the carbon steel products and / or in the subsequent rolling break and frees the rolling mill from the loose scale of the carbon steels.
- FIG. 3 schematically shows a plant for casting and rolling thin slabs with a casting strand for thin slabs and a process route for a conventionally cast product according to a second embodiment
- FIG. 4 schematically shows a plant for casting and rolling thin slabs with two casting strands and a common rolling train according to a third embodiment
- the first process route I comprising a rolling mill 3 with a casting machine 4 arranged upstream.
- the first casting machine 4 has a distributor 5 and a funnel-shaped thin slab casting mold (shown here schematically larger) for the casting of thin slabs 40-100 mm thick.
- the casting machine 4 itself is fed with stainless steel melt from pans 7, the steel melt being produced, for example, by means of a blast furnace converter route (denoted by 8) or by means of an electric steel furnace with downstream secondary metallurgy and being transported to the casting machine in the pans 7 (the transport step is labeled 9).
- the cast product in the form of the cast strand is bent from the vertical into the horizontal via rollers 10a, b and, in this embodiment, is separated by means of a first cross-cutting shear 11.
- the individual thin slabs then run into a first compensation furnace 12, for example a roller hearth furnace or walking beam furnace, in order to achieve a uniform thin slab temperature.
- a descaling device 13 the thin slabs are conveyed into the rolling mill in order to achieve the desired final dimension.
- the finishing mill 14 of the rolling mill here consists of six rolling stands (15a by way of example), each with two working (16a, b) and backup rolls (17a, b). This is followed by an outfeed roller table 18 with cooling devices 19 and a reel 20 for winding the strip into the coil.
- the system according to FIG. 1 shows a second cast product as cast strand 2 made of carbon steel in a second, parallel process route II.
- This process route consists exclusively of the compensating furnace 21 from the same structural units as the process route I described above, which is therefore not discussed in detail.
- the first process route as an integration unit for the thin slabs from the second process route II, comprises a ferry 22 which can be inserted transversely into a section 22a of the first compensation furnace 12 which can be moved to the other side.
- a common rolling program is run in the rolling mill 3, an example of such a rolling program being shown in FIG. 2.
- the respective steel grade is plotted on the number of strips.
- the rolling program begins with the rolling of a stainless steel cast product, followed by a cast product made of carbon steel etc.
- the sixth to eighth slabs are then made of carbon steel, the 12th to 16th as a group made of stainless steel.
- Figure 2 serves only as an example of a possible common rolling program.
- the stainless steel rolling results in rougher roll surfaces that would have a disruptive effect on the subsequent rolling of carbon steel, such as, for example, by rolling in scale and rougher strip surfaces.
- the rolling mill therefore has grinding and / or polishing machines which are arranged on each of the roll stands.
- An example of such a device, which acts on the upper and lower work roll, is identified by 23.
- an edge heater 24 is provided is arranged in front of the descaling device 13. For example, it is an induction heater or gas-fired heater.
- Devices for lubricating the roll gap to reduce the friction between the work rolls are also provided, shown here by way of example at 25. These are in particular only arranged on the inlet side of the roll stand.
- wear-resistant rollers such as work rollers, which are manufactured using the powder metallurgical H1P (high-isostatic pressing) process or high-speed steel (HSS).
- H1P powder metallurgical H1P (high-isostatic pressing) process or high-speed steel (HSS).
- H1P high-isostatic pressing
- HSS high-speed steel
- the surface inspection is preferably aligned with scale rolling and strip roughness.
- the loose scale that is formed during the rolling of carbon steels, which could be pressed into the surface of a subsequently rolled stainless steel strip, is removed in the strip side guides by means of a flushing device (designated 27 by way of example).
- a flushing device designated 27 by way of example.
- This preferably works in such a way that the wipers (not shown) of the flushing device are temporarily pivoted away and during this time the flushing medium is applied to the roller surface and between the stands at high pressure by means of appropriate high-pressure nozzles (not shown) in order to flush out any scale or grinding particles ,
- the strip quality can of course also be improved by the use and controlled control of profile actuators for shifting work rolls and setting a roll bend. It is proposed the sequence of the entry of a first thin slab, a group of first thin slabs, ie from the first process route I, a second cast product or a group of second cast products into the rolling mill and the duration of the common rolling program, ie the period between the change of the To determine work rolls, computer-based on a process model. On the basis of this process model, the use and the period of the grinding and polishing devices or the rinsing devices for removing the scale of the carbon steels and the other devices which are intended to improve the strip surface are also controlled. Such a control unit is designated schematically at 28. In addition, the permissible jumps in the width of the cast products to be rolled in succession can be taken into account in this rolling program in accordance with mixed rolling. Overall, such a process model enables the rolling quality to be optimized as a function of the desired product quality.
- the second casting products (2) integrated into process route I are cast using a conventional casting machine 30 with thicknesses of up to 250 mm and, after cooling and reheating in an oven 31 in a roughing mill 32, to a thickness as far as necessary rolled down that they can be integrated into the common rolling mill of process route I.
- the conventional process of continuous casting and roughing is only shown schematically here.
- the individual slabs are transported in the cold or possibly still warm state to a slab furnace 21 in the vicinity of the first process route I, where they are heated or homogenized to corresponding rolling temperatures and introduced into the compensating furnace 12 by a ferry 22.
- FIG. 4 schematically shows a third embodiment of the plant with which a common rolling program is carried out.
- the integration unit is a ferry 220 which carries both the cross-divided first and the second cast products (100, 200) from the two equalizing furnaces (120, 210) and thus process routes I and II come into a common rolling mill 300.
- stainless steels can be produced more economically than according to the prior art, because free capacities of existing plants can be used or not used.
- heavy-duty systems which are primarily used to manufacture carbon steels, can be supplemented with other types of steel or other cast products.
