The influences of additives such as dolomite and soda,roasting time and process temperature on the roasting effect of chromium concentrate were studied.

Determination of major and minor components in chrome ore by X-ray fluorescence spectrometry;

Using the chrome ores from India and Tibet,middle/high-grade magnesia and fused magnesia as raw materials,the 50?mm×40?mm cylindrical specimens were compacted under 200?MPa and sintered at 1?700～1?750?℃.

It briefly probes into the meltability of chrome ore,electrical conductivity at high temperature,reductib ility as well as viscosity to provide some basis for rational proportioning ratio n of chrome ore in smelting HC FeCr.

Determination of Multielement in Chromite and Chromic Slag by Flame Atomic Absorption Spectrometric Method;

Effect of Cr powder addition on reaction and sintering between magnesia and chromite powders

The reduction of chromite is discussed theoretically.

The dissolution behavior of compact chromium ore with definite shape in CaO-SiO_2-MgO-Al_2O_3 slag system was studied, and the effect of different slag compositions on the dissolution amount and rate of chromium ore in slag was investigated.

To reveal in depth the smelting/reduction mechanism of chromium ore in converter,the dissolution rate of natural chromium ore in definite shape in CaO-SiO2-MgO-Al2O3 slag system was determined,and a kinetic model for its dissolution process was developed on macrokinetics theory.

Aiming at the thermodynamic problems in the process of chromium ore smelting reduction and direct alloying for stainless steel,the theoretical analysis and calculations have been carried out by thermodynamic diagram and isothermal equation.
