expression for slag milling peocess

the slag-metal reactions in steelmaking process. Many slag models have been proposed to express the ther-modynamicproperties of silicate melts. Someof the modelswere successful for the mathematical expression of slag-metal reactions in a restricted range of slag composition, but the samemodelswere inadequate for the data from other sources

    Feb 15, 2017 Slag milling indicates the superior efficiency of high-energy milling, which allows a maximum slag finesse of 1.79 m 2 /g after 3 h of milling. Major structural changes occur during the first 3 h of high energy milling while conventional milling does not induce any remarkable trend
