In order to make sure whether the Cr2O3would change to Cr6+during the service, 4wt % Cr2O3was added to the calcium aluminate cement bonded Al2O3-SiC-C castables for blast furnace main trough, then the phase evolution was analyzed through thermodynamic calculation done by Factsage 6.1 under air atmosphere, which is close to its real work conditions. Calculations results show that Cr2O3was reduced to Cr3C2with low air amount, with amount of air increase, Cr3C2transformed to Cr4C and Cr5Si3successively, and turned to Cr2O3at last with much more air, and no compound including Cr6+was founded.

In the process of centrifugal dry granulation of blast furnace slag, the thickness of the liquid film at the outlet of the rotor will have a significant impact on the degree of crushing of the slag after leaving the rotor and the size of the solid particles formed. Therefore, this paper uses the VOF method to analyse the flow of molten slag inside the cup. The results have shown that the slag flow has a significant effect on the thickness of the liquid film and the linear relationship is obvious; the thickness of the liquid film decreases with the increase of the diameter of the rotary cup and the rotation speed, and the negative correlation with the diameter of the cup is more obvious; Secondly, as the depth of the cup increases, the thickness of the liquid film decreases first and then increases. The inclination angle of the cup wall has little effect on the thickness of the liquid film.

The physical and chemical processes in the raceway zone of the COREX melter–gasifier express are similar to those inside the blast furnace. Based on the research achievements on blast furnaces, the unsteady numerical simulation of a gas-solid two-phase in the raceway was carried out by using computational fluid software. The formation process of the raceway in the COREX melter–gasifier was simulated. The shape and size of the raceway were obtained. Then, the effect of gas flow on the depth and height of the raceway was analyzed in this paper.
