Ladle is the main thermal equipment for loading molten steel. In the process of loading and transporting molten steel, due to the heat loss at the mouth of the ladle, many steel plants have chosen to increase the ladle roof to reduce the heat loss in recent years. There are many types of unshaped refractory materials for ladle lids, but the refractory castables used for ladle lids that can improve the use effect of ladle lids need to choose suitable castables according to the actual use environment.
The castable for ladle roof can choose high-aluminum mullite castable or low-cement steel fiber castable. High-aluminum mullite castable is to choose high-quality high-alumina bauxite as refractory aggregate, and add appropriate refractory powder according to the formula. The low-cement steel fiber refractory castable is a kind of refractory castable added with steel fiber. Steel fiber can improve the wear resistance and flexural performance of the castable. The low cement content can effectively improve the overall high temperature resistance of the castable. As the lining of the ladle roof, it can effectively resist the corrosion of molten steel gas and molten slag.
The ladle delta castable can be directly poured into the ladle roof mold during use. The high-alumina mullite castable has excellent high temperature performance, high compressive and flexural strength, and good volume stability. Because high alumina bauxite has good heat vibration performance, as the main raw material of the refractory castable for the ladle roof, can increase the service life and use times of the ladle, reduce the maintenance frequency of the ladle roof, effectively increase the turnover speed of the ladle, speed up the steelmaking production rhythm, and ensure the quality of molten steel. And production anterograde played an important role.
