USE OF MAGNESIAN-DOLOMITE MIXTURES IN STEEL-MELTING FURNACE HEARTHS AND THE MECHANISM OF THEIR WEAR IN SERVICE. 1. STUDY OF JEHEARTH REFRACTORY MIXTURE

摘要

The results of mineralogical-petrographic analysis of Jehearth magnesian-dolomite refractory mixture used in the hearths of steel-melting furnaces are described. The variation regularities of its phase and chemical composition are identified and the mechanism of its wear in service at the metallurgical works in Russia is considered.
