Abstract
The use of complex injection in converters permits intensification of oxygen injection and steel output and also reduction in the injection time, the oxidation of the intermediate product, the carbon content in the metal after injection, and the total iron content in the slag. In addition, the consumption of reducing agents and ferroalloys is reduced for all steel and the range of steel with carbon and phosphorus content is expanded.
