作为解决连铸用浸入式水口Al2O3黏附问题的手段,采用了无碳的Al2O3-SiO2系难黏附材质配置在浸入式水口的内孔。但从预热到浇注时间长时,或低温浇注时,钢水会凝固在水口的内表面。本文将研究低熔点硅的添加量,提高表面平滑度的材质,并评价其黏附效果的特性。在以往难黏附材料的 As a means to solve the problem of adhesion of the submerged entry nozzle Al2O3 for continuous casting, a carbon-free Al2O3-SiO2 hard-adhesion material is disposed in the inner hole of the submerged entry nozzle. However, from preheating to casting a long time, or low temperature pouring, the molten steel will be solidified in the nozzle’s inner surface. This article will study the addition of low-melting-point silicon, improve the surface smoothness of the material, and evaluate the adhesion properties. In the past it was hard to stick to the material
