Abstract:

In this article,the impact of spinel additives amount on properties of corundum spinel brick is studied based on raw materials of white corundum, tabular corundum,spinel and alumina powder.By comparing the properties of the test samples, such as apparent porosity, bulk density,cold crushing strength,modulus of rapture under high temperature,thermal shock resistance and LF slag corrosion resistance,the result shows that all the properties of corundum spinel brick are excellent when the spinel additives remain between 10% to 20%.
