Abstract

Изобретение относится к металлургии, в частности к подготовке шихтовых материалов для производства ферросплавов. Технический результат - упрощение способа, повышение безопасности при производстве брикетов, обеспечение утилизации мелких фракций отходов в виде пыли, улавливаемой в системе газоочистки при производстве высокоуглеродистого феррохрома и при производстве ферросилиция. Указанный результат достигается тем, что в способе получения брикетов для производства феррохрома, включающем подготовку путем перемешивания порошкообразного материала и связующего, содержащего цемент, прессование брикетов и их сушку, согласно изобретению, в качестве порошкообразного материала используют хромосодержащую пыль, а в связующее добавляют микрокремнезем, при следующем соотношении компонентов, мас.%: хромосодержащая пыль фракции менее 5 мм: 85-90; микрокремнезем: 3-8; цемент: остальное, прессование брикетов осуществляют при давлении не менее 5 МПа, а сушку ведут при температуре 20-40°С. Используют хромосодержащую пыль, улавливаемую в системе газоочистки при производстве высокоуглеродистого феррохрома, и микрокремнезем в виде пыли газоочистки, получаемой при производстве ферросилиция.The invention relates to metallurgy, in particular to the preparation of charge materials for the production of ferroalloys. The technical result is a simplification of the method, increasing safety in the production of briquettes, ensuring the utilization of small fractions of waste in the form of dust captured in the gas cleaning system in the production of high carbon ferrochrome and in the production of ferrosilicon. This result is achieved in that the method for producing briquettes for the production of ferrochrome, including preparation by mixing powdered material and a binder containing cement, pressing briquettes and drying them, according to the invention, uses powdered chromium dust as a powdered material the following ratio of components, wt.%: chrome dust fraction less than 5 mm: 85-90; silica fume: 3-8; cement: the rest, pressing briquettes is carried out at a pressure of at least 5 MPa, and drying is carried out at a temperature of 20-40 ° C. Chromium-containing dust trapped in the gas cleaning system during the production of high-carbon ferrochrome is used, and microsilica in the form of gas cleaning dust obtained during the production of ferrosilicon.
