%X Simulative study for erosion of refractory in VOD or AOD steel refining was car- ried out by the method of rotating cylindrical magnesite-chrome specimen immersed in a synthe- tic molten slag. It was resulted that the dissolution rates of specimens with contents of same Cr_2O_3 but various Al_2O_3 are the same at the ratio Al_2O_3/MgO from 0 to 0.085% and increase sharply from 0.085 to 1.14% then smoothly over 1.14%. With the increasing of Al_2O_3 content in the slags, the dissolution rates of specimens decrease, and their decrement meet each other at 25% Al_2O_3 in slags. The microcopic observation and EPMA were also made of the eroded specimens.
