主　　题：ferrochrome slag Cr\+\{6+\} green cement clinker 

摘      要：Ferrochrome slag is a kind of industrial waste containing Cr\+\{6+\} and is produced in the process of silico ferrochrome smelting. On the basis of analyzing the chemical composition and mineral composition of ferrochrome slag, this paper has put forward a technology of green portland cement clinker calcinated from ferrochrome slag. In the experiment, physical chemical changes of cement clinker in the burning process of ferrochrome slag were investigated. The effects of calcinating temperature and clinker cooling rate on the solubility value of Cr\+\{6+\} were analyzed. The results indicated that when the calcinating temperature is above 1450℃, and the cooling rate is beyond 120 ℃/min, Cr\+\{6+\} in cement clinker is almost insoluble.
