Especially for the violent mixing in HTM, refractory can also be im- pacted by molten metal (iron or steel), so it is very important to study and find out new refractory to meet the demand of HTM. Suitable refractory not only can stand the eroding of slag and liquid metal, but also can reduce the loss of electromagnetic energy. According to the experimental results, the influence of different refractory on electromagnetic force is unconspicuous, the refractory with Al,O,-base is better than that with MgO-base for standing the erosion by slag and iron. Al,O,-base refractory is more suitable for HTM process.展开更多
