PROCESS FOR MAKING IMPROVED HIGH ALUMINA REFRACTORY CEMENT CONTAINING MG-AL SPINEL FROM DOLOMITE.

摘要

The present invention relates to the process for developing high alumina refractory cement comprising spinel phase and the said spinel phase comprises magnesia and alumina from dolomite and calcined alumina source. The said process comprises steps like selection of viable compositions comprising suitable percentages of dolomite containing cementing phases, preparation of refractory cement samples from said compositions for treating of cementing properties, characterization and optimization of different phases of refractory cement based on X-ray diffraction properties and identification and formation of high alumina refractory cement comprising 30 to 35 % spinel phase.
