Abstract:Free CaO will exist in BOF slag whose basicity is bigger than 2. FCaO is the main component affecting the volume expansion ratio of BOF slag. In present study, different ratio of BF slags are added into smelting BOF slag. The microstructures of the slag product are analyzed with SEM method, meanwhile the stability of BOF slag before and after the reaction are measured and compared with steam test method. Results show that when adding BF slag into melting BOF slag,the stability of the slag can be increased obviously, and the cooling way affects the structure of the product but it has a little effect on the expansion ratio of slag.This method gives evidence for application of BOF slag.
