Focus on refractory production
The tundish type magnesia air curtain wall adopts magnesium banknote as the main raw material, and the admixture is added. It is formed by machine molding and fired at 1600C high temperature.
The structural feature is that a plurality of through pores are formed by firing at a high temperature by an appropriate particle grading and an action of an admixture, thereby forming a diffused gas permeable method. In use, the gas passes through the air curtain retaining wall to form a bubble curtain, which can increase the floating opportunity of impurities, reduce the dead volume of the molten steel in the tundish, and has a significant effect on reducing minute inclusions in the molten steel.
