Introduction of continuous casting equipment
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 a complete set of continuous casting equipment. The electro-hydraulic integration of steel casting equipment, continuous casting machine body equipment, cutting area equipment, ingot bar collection and conveying equipment constitutes the core part of continuous steel casting equipment, which is customarily called continuous casting machine.
Main equipment combination: vibrating table, crystallizer, tension leveler, flexible (rigid) starter bar traction, roller path, conveying track, push steel storage, Siemens frequency conversion electric control, pump station, etc., reasonable design, low investment, and effective It is fast, saves materials and the building area of the plant, and is an ideal supporting equipment for small and medium-sized steel plants.
The arc continuous caster adopts multi-roller transmission, disperse the tension, and adopts continuous straightening, so as to minimize the deformation rate of the cast billet surface and between the two phases. It is beneficial to improve the quality of the cast slab and prolong the service life of the equipment. The steel tube of the mold of the continuous casting machine is arc-shaped, and the inner wall is treated with hard chromium to increase the service life. After the molten steel is encrusted in the mold, it is adjusted by one or two sections of cooling water and receives spray cooling along the arc-shaped track. Then enter the straightening machine, cut to length after full curing.

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