Converter smelting of steel with preliminary scrap heating to reduce hot-metal consumption

Abstract

The consumption of hot metal in slag preparation and slag-coating application in the converter may be reduced by scrap heating. The thermal equivalents of the coke additions and coke consumption in smelting to ensure the required metal temperature at tipping are determined. The basic principles for converter technology with preliminary scrap heating are developed, and experimental data are obtained regarding the efficiency with which the carbon-bearing fuel (coke) is used, so as to improve the thermal balance of the converter process and the final characteristics of steel production.
