With cooling channels' such as cooling grooves, cooling groove holes or cooling holes. [Prior art] The continuous casting ingot mold used for the conventional construction method of steel ingots (vorbl0cken) or steel plates before continuous casting from steel, is a csp (compact strip production) in the form of a plate ingot mold. Side walls, these side walls are composed of _ support and -in & (it is on the support, contact with the molten iron). Refrigerant channels which are parallel to each other are preferably provided on the side of the inner plate facing the support wall, and they can be designed in the form of slot openings facing the support wall. In the case of a CSP ingot mold of an actual structure, the relationship between the heat transfer effect and the height of the ingot mold, especially in the area above and below the tank level surface, may change within a certain limit. For example, S, the temperature of the mold wall gradually decreases above the liquid level surface. However, if the thermal transition effect in the area of the tank level surface and / or the area above ^ is reduced and the temperature of the ingot mold increases, this has the following advantages:-First, because the ingot mold is hot in the area of the tank level surface, Therefore, the foundry powder dissolves faster; '——As the foundry powder dissolves faster, the lubricating effect between the strip and the ingot mold is improved, and as a result, the surface quality of the strip is better. — First, due to better lubrication, the temperature of the surface of the ingot mold below the tank level surface is 200400093, which lowers the thermal stress and reduces the tendency to form cracks, so the service life of the ingot mold is prolonged; The upper ingot mold area is hotter, reducing stress in the area below its plane. This can also reduce the occurrence of cracks and extend the service life of the rotary die. By measuring on the continuous casting ingot mold, it can be known that 'the area between 20 ~ 80ππη below the tank liquid level has a maximum heat flux distribution, and from this area, along the casting direction and inverse Along the casting direction, the shape of the distribution curve is a shovel curve. Here, the area with a high heat flux density is about 120 mm. The correlative graph of the temperature distribution of the molten iron in the ingots corresponds to the curvature of a reclining parabola, while in the region of higher flow density. The German patent DE 38 40 448 C2 mentions a continuous casting ingot mold, especially a plate ingot mold, the side walls of which are each composed of a support wall and an inner plate, the inner plate is fixed on the support wall and is in contact with the molten iron, On the side of the inner plate that supports the soil inward, opposite refrigerant channels are provided. They are designed in the form of slot holes that open toward the support wall. The width of the slot holes is smaller than the width of the ribs between the slot holes. The slot depth is greater than the rib width. District Renzhou patent EP 0 551 311 B1 mentions a liquid-cooled, adjustable-width plate ingot mold, which is used for continuous casting of steel strips in a steel plate format (especially for those thicker than M 1GG_). In this sharp mold, the wide side plate and the narrow side: the direction of the extension of the plate is designed to make the cross-section of the strip larger, narrow, and the plate is set to be substantially parallel to each other along the height range of the ingot mold, and the wide side plate is at least The area where the width of the small steel plate is taken is designed to be concave, so that when viewed in cross section, the chord height (swell height) of these 200400093 kinds of arc mold wall (Scheitelh0he) is relative to that on the casting side of the mold. An inscribed rectangle extends up to 12mm south of the steel plate per 1000mm width, and the shape of the wide side plate at the strip exit end of the ingot mold corresponds to the strip format to be produced. The wide side plate is designed as a flat surface within the adjustment range of the narrow side plate, and a slot-type channel is provided in the side facing away from this shaping side. European patent EP 0968 779 A1 mentions the design of a wide side of a steel plate ingot mold, which has a cast plate, the cast plate has an inner surface and an outer surface that is opposed to the inner surface, wherein the wide side has an upper partial area and a lower portion A partial region, wherein at least the upper partial region has a middle region and two side regions provided on its side. Claimed in this document. The inner surface of the cast plate is provided with a groove having an undercut W (Hinterschmeidung, English: undercut) to form a cooling channel, and the groove is covered by a filler in a form-joint manner, and the filler is placed in the undercut. US-Patent 5, 207, 266 refers to a water-cooled copper rotary mold 'it contains a copper plate' with a rear-facing frame fixed on it, forming a cooling channel ', wherein the main channel is on a fixed pin ( Bolt) area is wider than in other areas. The ingot mold contains a larger channel design, and the area of the fixing pin is between the channel on the right and the left (excluding the screwed part of the bolt). A branch channel is provided between the main channel and the enlarged channel, and at least the branch channel and the branch area of the main channel have a larger water area area than the main channel and the enlarged channel. In order to form a crack-free strip shell quickly, surely, and especially uniformly, it is advisable to start from the area under the crescent (Meniskus) 200400093 until the exit opening of the rotary die for intensive cooling or heat conduction. from. For this reason, the conventional rotary mold can make the following possible measures: Adjust the faster cold water speed,-reduce the cold water temperature, and use the ribs in the cooling channel to increase the heat exchange area. The various modifications described above have been applied to practically various designs of ingot molds for continuous casting equipment. The contact plate of the ingot mold (which is generally composed of a copper alloy) is in direct contact with the liquid and solidified metal (hot metal) Γ ". The contact plate (also called "copper plate") is a wear (expendable) part and is fixed to a carrier (mostly made of steel). This reusable (W1ederverwerten) carrier board component is called a "water tank". The ingot mold itself acts as a crystallizer. In other words, a lot of energy is extracted from the molten iron to form a bearing strip shell, and the strip shell is continuously pulled away from the ingot mold. . Here, the first strip is formed on the so-called crescent at the height of the mlstand in the ingot mold. "Crescent" means the zone of early occurrence of strip shells, in which the contact surface of the ingot mold, solid and molten casting aids, and the strip shell of molten iron meet. The casting aids used are foundry powder and oil. They are lubricated by separating gold 4 (hot metal) and copper from each other and controlling local transfer (Figure 8). The first strip volume formed on the crescent is passed through the ingot mold in a "pull / again" manner. Due to the 200400093 degree temperature gradient between the molten iron and the refrigerant, a local energy flow is caused in the direction of the cooling channel. The thermal energy contained in it is dissipated by this cooling channel (they are flowed through by refrigerant—mostly water). The strip shell thickness also increases correspondingly. The cooling channels formed in the die structure can be made entirely inside the copper plate or inside the water tank element. Learners also have their hybrid construction types. In addition, there are also widely used modification methods, in which the filling member is arranged between the water tank and the copper plate, which can cause an appropriate cooling channel. For reasons of manufacturing technology, cooling channels with rectangular or circular cross sections are widely used. The corner area can be rounded into a smooth shape. However, the U-shaped, L-shaped, and τ-shaped design of the contact surfaces can also be made by using appropriate fillers. Typical cooling channel devices follow the casting direction individually or in groups for s, from top to bottom, and most are at equal intervals from the contact surface with the molten iron. The purpose of this design is to achieve the most uniform cooling effect through the contact surface of the ingot mold, which can only be achieved conditionally in the area of the fixed position. Often, cooling channels with different cross-sectional areas and different geometric shapes are combined adjacently, and the uniformity of the cooling effect along the casting width range is further optimized (Figure 10). "All these types of construction have one thing in common, namely that the geometry of a single cooling slot remains the same in shape and cross-sectional area along its length. This practice 'makes cooling channels available for cooling in the length of the cooling channels. Face j: keep not t. With this quantity balance along an imaginary flow line, it is clear that the flow velocity along the length of this cooling channel remains the same. In this regard, there is only one special type of cooling channel hole, The "central displacement pin" can be put into the cooling channel hole from top to bottom. Since the length of the displacement pin is generally shorter than the length of the hole itself, the cross-section becomes smaller in the cooling channel, which accelerates the refrigerant in this transition area. In this way, in the area where the cross section becomes narrow, the refrigerant flows faster, and the cooling effect is correspondingly enhanced. However, with this measure, the effective cooling surface of the cooling channel has not been touched. The conventional structural design of the cooling channels so far has pursued as uniform cooling as possible, and the heat load distribution of the uneven sentence actually existing on the ingot template in #

According to the required multidimensional (multidimensional) considerations, the unevenness in heat load distribution can be divided into two types: unevenness parallel to the casting direction, and unevenness perpendicular to the casting direction. In the cooling material towel, the heat transfers (transfers) from the molten iron along the casting direction.

All other parameters are set to be strange, Then, if I ', the pre-work: the heat flow has its maximum value at the surface of the casting fluid y 11 200400093, and so it continuously decreases in the direction of casting. Integrate along the entire length of the cooling passage to derive the average heat flow. Due to the mul tipie dimensionality of heat conduction—there is no heat above the level surface of the prayer, the theoretically sharp shape of the heat flux density is smooth, and the position of the maximum value moves in the casting direction (section (Figure 9) The operation measurement of the local heat flux density in ° ° shows that relative to the average heat flux, the local value in the area of the casting liquid level surface is 1.5 to 3 times higher. On the contrary, the value at the foot of the die is as low as Its 0.3 ~ 0.6 times. The position of the maximum value depends on the equipment and program parameters, and it is located 20 to 70 mm below the original casting liquid level. The absolute value of the average heat flux is affected by the casting powder on the one hand, but also by the casting speed on the other. Therefore, in this document, the flat heat flow density is 10 MW // m 2 at a casting speed of 0.9 m / min, and 2.0 MW // m 2 at a casting speed of 3.0 m / min, at 5 3'OMW / m2 at a casting speed of 5 m / min. Using the above factors, at least 5 levels can be used to estimate the expected local heat flux. Due to the uneven distribution of the heat flux density in the casting direction, the main thermal wear on the ingot template occurs almost without exception in the area of the casting level surface. This wear is manifested in the form of rifts, fissures, deformations, and possibly even Abplatzung. In the width direction, the load of the ingot template is completely different. The inhomogeneity is mostly due to the molten iron flow formed in the money mold. These processes are closely related to the geometric design of the molten iron supply pipe (TauGhausguB), the geometry of the contact surface, and other program values. The process of fixing the position at the location of the foundry plane and the establishment of 4 non-ma mouths (instationary) resulted in the formation of this new average Γ (mostly different depending on the equipment). This kind of unevenness is evenly distributed :::: 10 into an uneven heat distribution. The main damage is not… formed along the width of the ingot mold, but occurs at a specific location. This article is aimed at the above-mentioned advanced technology. The purpose is to use a special geometric design of the heat transfer surface area of the cold channel, so that the cold material of this ▽ P channel has a decisive heat transfer effect. It can match the local heat flow density of the contact surface of the hot metal of the key mold. The purpose of thinking is to use the characteristics of the first main invention of the scope of patent application to achieve 0 people. His influence on the heat transfer and cooling effect of the invention (for example, for the cold material of the channel) can be seen in the towel. Patent The range subordinate items are placed here. For example, to affect the local cooling effect of changing a channel, its shape, cross-sectional area, periphery, nature of the boundary surface, directionality, and the way of setting relative to the contact surface can be locally changed. In addition, for example, the effective heat exchange area on the bottom or side walls of the channel can be increased or decreased. For example, 'by forming grooves (Riefen) on the bottom or side of the cooling channel, the surface area can be greatly increased by almost two times, so that at the same refrigerant flow rate, it results in a higher heat flux density and a much more dense cooling effect. And, there is a significant advantage · The temperature of the ingot mold is greatly reduced, so in addition to the less material load on the ingot mold, the water pressure of the cooling water can also be reduced. Here, for example, a comparative temperature calculation yields the following values: The smooth surface of the heat exchange surface at the bottom of the cold part 13 200400093 173 ° C to water temperature 507t to strip temperature 131 ° C to The temperature of water according to the present invention has a large surface area of 462 ° C.

The method to reduce heat transfer on the tank level surface is to insert the box in the cooling hole above the tank level surface, and cover the hole above the tank level surface, above the tank level surface. A charge made of a material with a lower thermal conductivity is placed. At the same time, the stress in the ingot groove is reduced due to a hot area of the ingot mold above the level surface of the groove, and thus the occurrence of cracks in the strip is reduced, while the availability of the ingot mold is improved (Verftigbarkeit, English · availability) 0 Here, it is particularly appropriate to take the following measures: by making changes along the height range of the ingot mold to match the uneven distribution of its heat flow density, the heat of the heat transfer surface area of the cooling channel is conducted away. … 200400093 In this way, in this ingot mold, the temperature trend along the height range of the ingot mold can be evened out ', and the material of the strip shell that is being produced can be prevented from being subject to greater stress and cracks.
