On the basis of laboratory experiments on the foaminess of arc-covering slag and the coexistence theory of the slag structure, the optimum composition. of the arc-covering slag for ladle furnace are determined. A series of foaming reagent prescriptions have been developed and applied for the patent of P. R. China. The industrial experiment of the arc-covering refining slag has been made with several hundred heats, and good technico-economic indexes have been obtained.
