After the molten steel in the ladle is refined by continuous argon blowing through porous plugs, it will be sent to the continuous casting machine. The role of continuous casting is to continuously cast the refined molten steel to produce the final product of steelmaking: qualified steel ingots or billets.
The molten steel in the ladle is porous brick After refining is completed by continuous argon blowing, it will be sent to continuous casting. The role of continuous casting is to continuously cast the refined molten steel to produce the final product of steelmaking: qualified steel ingots or billets.
The molten steel produced from the converter is received by the ladle, and after argon refining through porous bricks, it will be cast into billets of the corresponding shape according to the steel plant's production process and requirements. The main equipment of the continuous casting section includes a turntable, intermediate vessel, crystallizer, cooling nozzle, flame cutter, etc.

The quality of steel ingots or billets is largely related to whether the continuous casting process is smooth. The steps of continuous casting are as follows: argon blowing porous brick After refining, the ladle is transported to the turntable. After the turntable rotates to the pouring position, the molten steel is poured into the intermediate vessel, and then the molten steel is distributed to each crystallizer through the nozzle. The crystallizer is one of the core equipment of the continuous casting machine, which is a forced water-cooled bottomless steel ingot mold that allows the molten steel to quickly take shape. The main function of the crystallizer vibration device is to make the crystallizer vibrate up and down, which is conducive to demolding. The straightening machine has the same function as the crystallizer vibration device. It can pull out the castings from the crystallizer, and after cooling and electromagnetic stirring, it is cut into slabs of a certain length.
