“…The melting point (release) of the final slag is 1590-1650 (1730-1750) ° C, that is, it meets one of the basic requirements for the properties of the slag. However, such slags have high melting temperatures and a narrow range of liquid-mobile states, which is the main cause of metal losses with slag [4][5][6]. At the same time, a significant amount of chromium is lost in the form of beads.…”

The study of the effect of the properties of high-carbon ferrochrome slags on the creation of favorable conditions for the deposition of metal beads with the introduction of the following fluxing additives in an amount of 3-10%: slag produced by refined ferrochrome (stale and stabilized), cryolite, fluorite, feldspar, colemanite, fused borate ore, aluminum slag of aluminum production. The influence of the type and quantity of fluxing materials on the viscosity and crystallization temperature of high-carbon ferrochrome slags has been studied. It is noted that the use of all types of fluxing materials under study leads to a decrease in the crystallization temperatures of the processed slag. It can be seen from the results of metallographic and phase analyses that the best values for the degree of coagulation and deposition of metal crowns were achieved with the introduction of aluminum slag, colemanite and borate ore.
