Use of magnesian-dolomite mixtures in steel-melting furnace hearths and the mechanism of their wear in service. 1. Study of Ankerharth refractories

The results of mineralogical-petrographic analysis of Ankerharth magnesian-dolomite refractory mixtures used in the hearths of steel-melting furnaces are described. The regularities of changes in their phase and chemical compositions are identified and the mechanism of their wear in service at the Omutninskii Metallurgical Works is considered.
