K E43 Steel Plate

Consider the Shape and Size of the Steel Plate

 

Shape Matching

 

For the production of flat - shaped steel plates, a slab - type mold is usually chosen. The inner cavity of the slab - type mold is rectangular, enabling the molten steel to solidify into a plate - shaped shell within it. This shape matches the final shape of the flat - plate steel, which is beneficial for subsequent processing operations such as rolling. For example, when manufacturing automotive body steel plates, using a slab - type mold can ensure that the molten steel solidifies into a billet suitable for further processing into a flat shape.

 

If square - or rectangular - cross - section special - purpose steel plates (such as square steel billets for building structures) are to be produced, a billet - type mold is a more appropriate choice. The inner cavity of the billet - type mold is generally square or a nearly - square rectangle, allowing the molten steel to solidify into the corresponding square - shaped shell and ensuring the shape accuracy and quality of the product.

 

Size Adaptation

 

The size of the mold (such as the dimensions in the length, width, and thickness directions) needs to be determined according to the target size of the steel plate. In the width direction, the inner - cavity width of the mold should be slightly larger than the target width of the steel plate to ensure that the molten steel can be smoothly filled during the continuous - casting process. At the same time, the shrinkage during the solidification of the molten steel should be considered. For example, when producing a steel plate with a width of 1000mm, the inner - cavity width of the mold may be designed to be around 1010 - 1020mm.

 

 

Combined with Continuous - Casting Process Parameters

 

Casting - Speed Adaptation

 

Different casting speeds have an impact on the selection of the mold. If the casting speed is relatively high, a mold capable of withstanding high - speed casting conditions is required. Such a mold usually has a good cooling system and structural strength to ensure that the shell can solidify uniformly and will not be torn during the rapid - casting process. For example, in some high - efficiency continuous - casting production lines, the casting speed may reach 2 - 3m/minute. At this time, a specially - designed high - performance mold needs to be used, with a more rational layout of cooling pipes that can quickly dissipate heat and ensure the solidification quality of the shell.

 

When the casting speed is relatively slow, the cooling - efficiency requirement for the mold is relatively low. However, attention should be paid to preventing solidification defects caused by the molten steel staying in the mold for too long. In such a case, a mold with a relatively simple structure but good heat - preservation performance can be selected to maintain an appropriate solidification state of the molten steel in the mold.

 

Cooling - Method Matching

 

Select an appropriate mold according to its cooling method (such as water - cooling, air - mist - cooling, etc.). The water - cooled mold is a relatively common type, which takes away heat through circulating cooling water. When producing thick - specification steel plates, due to the need for greater cooling intensity, a water - cooled mold may be more suitable because it can provide stable and relatively high - cooling efficiency. For example, for steel plates with a thickness exceeding 20mm, a water - cooled mold can effectively control the solidification speed of the molten steel.

 

 

Consider the Characteristics of the Steel Grade

 

Thermal - Conductivity Factor

 

For steel grades with low thermal conductivity, the cooling speed of the mold can be appropriately slowed down. For example, the thermal conductivity of high - alloy steel is relatively low. When selecting a mold, a mold with a relatively slow - cooling speed can be considered, or the cooling parameters can be adjusted to prevent problems such as stress concentration caused by an excessive temperature difference between the surface and the interior of the shell.

Solidification Characteristics of the Steel Grade

 

Some steel grades have special solidification characteristics, such as mushy solidification or lamellar solidification. For steel grades with mushy solidification, a mold capable of adapting to this solidification mode needs to be selected. This kind of mold may need to have a special inner - cavity shape or vibration mode to promote the uniform solidification of the molten steel. For example, during the solidification process of some stainless steels containing high chromium, it is in a mushy state. At this time, the selected mold should be able to ensure that the molten steel can smoothly form a shell in this special solidification state and avoid defects such as shrinkage cavities.

 

For steel grades with lamellar solidification, the cooling of the mold should ensure the stability of lamellar solidification. For example, some low - carbon steels solidify in a lamellar manner. The cooling system of the mold should enable the molten steel to solidify according to the law of lamellar solidification and prevent defects between layers.
