高铝电工钢不同于普通钢,在连铸过程中,钢液中的铝和保护渣中的SiO2发生反应,致使结晶器保护渣的特性发生很大变化,并导致漏钢等连铸事故,造成产量下降。日本品川耐火材料公司开发出高铝电工钢用新型结晶器保护渣。该保护渣可保持稳定的熔渣层厚度,消除了漏钢事故。此外,连铸浇次由1个浇次增加到多个浇次,促进了连铸产量的提高。
High aluminum electrical steel is different from ordinary steel, in the continuous casting process, the molten aluminum and SiO2 in the slag reaction, resulting in a great change in mold powder properties and lead to continuous casting and other accidents, Cause the output to drop. Japan’s Shinagawa Refractories Company developed a new high-alumina electrical steel mold powder. The flux can maintain a stable slag layer thickness, eliminating the steel leakage accident. In addition, casting pouring times by a pouring increase to a number of pouring, and promote continuous casting output.
