Abstract

FIELD: ferrous metallurgy; methods for production of low-phosphorus low-iron charge slag for smelting of ferroalloys based on vanadium, chromium and manganese. SUBSTANCE: introduced additionally into melted charge is material containing oxide of same metal at mass ratio of charge metal and oxide components of (0.15-0.4):1. When metal component of charge is used in form of crumbs of ferromanganese (Mn 65%, P 0.35%, C 8%) and oxide component in form of slime of blast furnace production of ferromanganese (FeO 6.5%; Mn 21.7%; PO0.35%, C 11.8) charge slag is obtained which contains Mn 45.9-52.3%, FeO 0.7-0.85%, PO0.062-0.075%. This slag is useful in production of manganese-containing alloys satisfying the requirements of the ferroalloys standards in force. EFFECT: increased yield of charge slag enriched with oxide of leading element and its higher degree of enrichment.

Изобретение относится к области черной металлургии, конкретнее к способам получения низкофосфористого маложелезистого передельного шлака для выплавки ферросплавов на основе ванадия, хрома и марганца. Цель - увеличение выхода передельного шлака, обогащенного оксидом ведущего элемента, и повышение степени его обогащения. Способ включает загрузку и проплавление в вагранке шихты из материала, содержащего металл четвертого ряда Периодической системы элементов Д.И.Менделеева, в состав проплавляемой шихты дополнительно вводят материал, содержащий оксид одноименного металла, при массовом соотношении металлической и оксидной составляющих шихты (0,15 - 0,4):1. При использовании металлической составляющей шихты в виде крошки ферромарганца (65% Mn, 0,35% P, 8% C) и оксидной составляющей в виде шлама доменного производства ферромарганца (6,5% FeO, 21,7% MnO, 0,35% P2O5, 11,8% C) получают передельный шлак, содержащий 45,9 - 52,3% MnO, 0,7 - 0,85% FeO, 0,062 - 0,075% P2O5. Этот шлак пригоден для получения марганецсодержащих сплавов, удовлетворящих требованиям действующих стандартов на ферросплавы.The invention relates to the field of ferrous metallurgy, and more particularly to methods for producing low-phosphorous low-iron smelting slag for smelting ferroalloys based on vanadium, chromium and manganese. The goal is to increase the yield of tailings slag enriched with oxide of the lead element, and increase its degree of enrichment. The method includes loading and melting in a cupola of a charge of a material containing metal of the fourth row of the Periodic Table of D.I. 0.4): 1. When using the metal component of the charge in the form of crushed ferromanganese (65% Mn, 0.35% P, 8% C) and the oxide component in the form of a slurry of blast furnace production of ferromanganese (6.5% FeO, 21.7% MnO, 0.35% P 2 O 5 , 11.8% C) a slag is obtained containing 45.9 - 52.3% MnO, 0.7 - 0.85% FeO, 0.062 - 0.075% P 2 O 5 . This slag is suitable for producing manganese-containing alloys that meet the requirements of current standards for ferroalloys.
