Experimental Research for Refractories Used in High-Turbulent-Mixer (HTM)-Reactor

The high turbulent mixer (HTM) process is benefit for improving the quality of iron and steel, but the refractory of the reactor is easy to be eroded by slag and liquid metal at high temperature. Especially for the violent mixing in HTM, refractory can also be impacted 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 Al₂O₃-base is better than that with MgO-base for standing the erosion by slag and iron. Al₂O₃-base refractory is more suitable for HTM process.
