What are the typical continuous casting and rolling processes? What are their characteristics? Typical continuous casting and rolling processes include CSP process, ISP process, FTSC process and controlled rolling process. CSP process features: The funnel-shaped crystallizer is adopted, so that the submerged nozzle can be easily inserted into the crystallizer, and a slab with a thickness of 50mm can be cast. It has the advantages of short process, simple and stable production, good product quality and strong market competitiveness. ISP process features: parallel crystallizer and liquid core reduction technology are adopted to reduce rolling force, and the selection range of process parameters is large, and the setting of process parameters ensures the stability and high flexibility of the process; FTSC process features: This process has three-point descaling, H2 crystallizer, dynamic soft reduction device, automatic control system of molten pool, fully hydraulic width automatic control rolling mill, roller kiln heating furnace and other technologies. It has considerable flexibility, with a wide range of cast steel, wide adjustable range of slab thickness and width, direct rolling and flexible operation. It is easy to adjust when there is a fault. Control process features: The temperature change in the continuous casting process of billet is calculated by using flat crystallizer, rotary descaler, ultra-low head arc caster and secondary cooling system, so as to determine the cooling mode, reduce bulging, control the thickness of billet shell, improve the surface quality, and produce hot-rolled coil of peritectic steel with LSR system. It has the advantages of high productivity and low product price.
