Crystallizer of square billet continuous casting machine

Abstract

The invention discloses a crystallizer of a square billet continuous casting machine. Fins are arranged between the outer wall of a square billet forming pipe and the inner wall of a diversion water sleeve to divide an annular cooling water channel of the diversion water sleeve into a plurality of cooling water flowing channel bodies; the fins are evenly distributed between the outer wall of the square billet forming pipe and the inner wall of the diversion water sleeve and arranged in the middle of the square billet forming pipe, and accordingly an upper cavity and a lower cavity are formed in the upper end and the lower end of the square billet forming pipe; and the ends, connected to a water inlet and a water outlet respectively, of a water inlet pipe containing a hose section and a water outlet pipe containing a hose section vibrate with the crystallizer, and the other ends, connected to a supporting frame of the crystallizer, of the water inlet pipe and the water outlet pipe do not vibrate. According to the crystallizer of the square billet continuous casting machine, the mass of a vibration part of the crystallizer can be decreased, the driving power is decreased, energy saving and consumption reduction are achieved, and meanwhile the billet casting quality is improved.

Description

technical field [0001] The invention relates to a crystallizer, in particular to a billet continuous casting machine crystallizer, which belongs to the technical field of billet smelting equipment. Background technique [0002] In the field of iron and steel smelting, continuous casting machines are used to cast molten steel output from converters or electric furnaces into fixed shapes. The converter or electric furnace pours the molten steel into the mold of the continuous casting machine, and the mold casts it into billets such as slabs or billets, and the billets are drawn to the roller table by the dummy bar to cool and form. The crystallizer is the billet forming equipment in the continuous casting equipment, and it is called the heart of the continuous casting machine. Its function is to forcefully cool the high-temperature molten steel continuously injected into its cavity through the cooling wall, export its heat, and make the molten steel gradually solidify into th...

AI Technical Summary

Problems solved by technology

The existing billet crystallizer generally has uneven heat conduction in the process of use, which leads to a high incidence of defects such as surface cracks, slag inclusions, scarring, and diamond deformation of the billet, and the quality of the billet is unstable, and the drive required for vibration Disadvantages such as high power of the equipment
