DISINTEGRATING SLAG STABILISATION METHOD Russian patent published in 2015 - IPC C21C5/06 

FIELD: technological processes.

SUBSTANCE: group of inventions relates to versions of a processing method of steel-making slag for its stabilisation. During the processing, to the composition of the steel-making slag there added is colemanite in the form of a natural mineral with a fraction of 3-90 mm in the amount of 0.5-1.5% of the weight of the processed slag during out-of-furnace treatment at the removal of slag from the ladle prior to steel degassing or in the ladle at its removal after pouring of steel treated on a ladle-furnace unit, or at treatment of steel in the ladle on the ladle-furnace unit.

EFFECT: reduction of the temperature and viscosity of the treated slag, uniform distribution of colemanite in the volume of the treated slag, reduction of duration of the slag formation and elimination of the impact of decomposition products on the environment.
