It was resulted that the dissolution rates of specimens with contents of sameCr_2O_3 but various Al_2O_3 are the same at the ratio Al_2O_3/MgO from 0 to 0.085% and increasesharply from 0.085 to 1.14% then smoothly over 1.14%. With the increasing of Al_2O_3 content inthe 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.
