Slab continuous caster

The continuous casting machines provided by SMG GROUP are designed to meet customer requirements and the conditions of their existing production lines.

Continuous casting is a process that lies between steelmaking and rolling. During continuous casting, molten steel at high temperature is continuously poured into one or a set of water-cooled molds, where it gradually solidifies around the mold to form a shell on the billet. When the liquid steel level rises to a certain height and the billet has solidified to a specified thickness, a straightening machine pulls the billet out, and water is sprayed in the secondary cooling zone to ensure complete solidification. According to rolling requirements, a cutting device then cuts the billet into specified lengths.

Continuous casting machines can be classified into various types based on their structure and process. Common types include vertical continuous casters, curved continuous casters, and horizontal continuous casters. Vertical continuous casters are among the most widely used; they have a simple structure and are suitable for producing thicker slabs. Curved continuous casters can produce wide slabs and are ideal for specialized applications. Horizontal continuous casters are well-suited for producing slabs with stringent surface quality requirements. These different types of continuous casting machines are extensively employed in the steel and non-ferrous metals industries, meeting diverse material and specification needs.

Slab continuous casting is a continuous steelmaking and ironmaking technology whose primary product is slab. Slabs are defined as having a width-to-thickness ratio greater than 3. Continuous-cast rolled steel slabs are mainly used for rolling flat sheet products (thick plates, medium plates, thin plates, and coils). Typically, the dimensions of slabs produced by continuous casting machines range from 150–250 mm in thickness and 1000–1800 mm in width; smaller slabs may measure 600 mm in width and 120 mm in thickness. Slabs with a thickness of less than 100 mm are referred to as thin slabs.
