The production process of continuously casting high-temperature molten steel into a slab with a certain cross-sectional shape and a certain size is called continuous steel casting. The equipment required to complete this process is called continuous casting equipment.

After more than 30 years of efforts, continuous cast steel has gradually replaced ingot mold casting. Continuous casting slabs with thickness of 150 ~ 250mm are widely used in various countries to produce plates. In the 1980s, continuous casting technology has made a breakthrough. At present, the continuous casting technology that can pour thinner slabs and higher pouring speed to make the production capacity have economic scale is developed
