Function of the continuous casting spare parts of the crystallizer
1. At the highest possible pull speed, to ensure the thickness of the lens blank shell, to prevent leakage, the thickness of the casting billet should be uniform.
2. The solidification of steel water in the lens has a significant impact on the casting surface quality and the normal production of the casting machine, so there are many requirements.
3. In order to solidify the steel water quickly, the inner wall of the lens shall have good thermal conductivity and water cooling conditions.In order not to unbond the solidified primary blank shell to the inner wall of the crystal device and have less friction, the lens shall be reciprocated with lubricant during pouring.
4. The billet is correct and to be rigid to avoid the deformation of the grator.

In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
