The role of continuous casting mold

The mold is a key component of the continuous casting machine. Its role is:

(1) At the highest possible pulling speed, ensure the thickness of the mold shell to prevent leakage.

(2) The peripheral thickness of the cast slab must be uniform.

The solidification behavior of molten steel in the mold has a significant impact on the surface quality of the cast slab and the normal production of the casting machine. Therefore, the following requirements are imposed on the crystallizer:

(1) In order to quickly solidify molten steel, the mold wall should have good thermal conductivity and water cooling conditions.

(2) In order to make the solidified primary green shell not adhere to the inner wall of the mold, the friction force is small, the mold should reciprocate up and down and add lubricant during the pouring process.

(3) In order to make the shape of the billet correct and avoid the deformation of the mold to affect the drawing, the mold should have sufficient rigidity.

(4) The structure of the crystallizer should be simple and the weight should be light.

The mold is lined with copper and copper alloy with very good thermal conductivity, and the outer jacket is covered with water for cooling. Its structure is divided into three parts: copper inner wall, outer jacket and sink.
