Continuous casting machine-what is it

The production process of continuously casting high-temperature molten steel into billet with certain section shape and certain size is called continuous cast steel.

The equipment required to complete this process is called continuous casting complete set of equipment. The electro-hydraulic integration of steel pouring equipment, caster body equipment, cutting area equipment, dummy bar collection and transportation equipment constitutes the core equipment of continuous cast steel, which is traditionally called continuous caster.

What is continuous caster?

Continuous casting machine production process. The high-temperature molten steel is continuously poured into one or a group of water-cooled copper crystallizers, and the molten steel is gradually solidified into a blank shell along the periphery of the crystallizer. After the steel liquid level rises to a certain height and the blank shell solidifies to a certain thickness, the tension leveler pulls out the blank, and the slab is cooled by water spraying in the secondary cooling area to completely solidify the slab, which is cut to a fixed length by the cutting device according to the requirements of steel rolling. This process of directly pouring high-temperature molten steel into billet is called continuous casting. Its appearance has fundamentally changed the one-off rolling process of steel ingots, which has dominated for a century. Because it simplifies the production process, improves the production efficiency and metal yield, saves energy consumption, greatly reduces the production cost and has good billet quality, it has developed rapidly. In today's steelmaking enterprises, whether it is long process steelmaking or short process steelmaking, the allocation of continuous caster is almost inevitable.

Continuous casting machine's classification

Continuous casters can be classified in many forms. According to the structural shape, the continuous caster can be divided into vertical continuous caster, vertical bending continuous caster, arc continuous caster with straight section, arc continuous caster, multi radius elliptical continuous caster and horizontal continuous caster. With the development of continuous casting technology, the research of wheel caster, especially thin slab caster, has been carried out.

According to the size and shape of the section cast by the continuous caster, the continuous caster can be divided into slab caster, billet caster, bloom caster, round billet caster, special-shaped section caster and thin slab caster. The square billet caster also includes the rectangular billet caster. Generally, the casting section or equivalent section area is greater than 200 × 200mm billet is called bloom, and the section or equivalent section area is less than 160 × A 160mm billet is called a small square billet, and a rectangular billet with a width thickness ratio greater than 3 is called a slab.

It can be divided into single flow, double flow or multi flow continuous caster according to the number of billet flows that can be cast by the continuous caster under the same ladle.
