Abstract
1. Способ производства ванадиевого шлака и легированной ванадием стали, включающий передел ванадиевого чугуна в кислородном конвертере на ванадиевый шлак и полупродукт, предусматривающий заливку ванадиевого чугуна в конвертер, продувку его кислородом и подачу охладителей, передел полупродукта на сталь, предусматривающий завалку в конвертер охладителей, заливку полупродукта, зажигание и продувку плавки кислородом, порционную присадку шлакообразующих по ходу продувки, выпуск металла в ковш, его науглероживание, раскисление, легирование и доводку, отличающийся тем, что в качестве охладителей используют гранулированный ванадиевый чугун с фракцией 5-15 мм и окалину, причем их суммарный расход составляет 90-235 кг/т чугуна. ! 2. Способ по п.1, отличающийся тем, что на первой стадии процесса в качестве охладителей присаживают 20-200 кг/т чугуна - гранулированный ванадиевый чугун и 70-0 кг/т чугуна - окалины, а на второй стадии процесса в качестве охладителей присаживают 20-60 кг/т металла - гранулированный ванадиевый чугун. 1. A method for the production of vanadium slag and vanadium alloyed steel, comprising redistributing vanadium cast iron in an oxygen converter into vanadium slag and a semi-product, comprising pouring vanadium cast iron into a converter, purging it with oxygen and supplying coolers, redistributing the semi-product into steel, filling in cooler converter, intermediate product, ignition and purge of smelting with oxygen, batch additive of slag-forming agents during the purge, release of metal into the ladle, its carburization, deoxidation, alloying e and refinement, characterized in that as the coolers use granulated vanadium cast iron with a fraction of 5-15 mm and scale, and their total consumption is 90-235 kg / t of cast iron. ! 2. The method according to claim 1, characterized in that in the first stage of the process, 20-200 kg / t of pig iron — granulated vanadium cast iron and 70-0 kg / t of pig iron — are scaled as coolers, and in the second stage of the process as coolers 20-60 kg / t of metal are planted - granulated vanadium cast iron.
