Abstract
Описується спосіб і блок для прямого плавлення металовмісного матеріалу. Винахід спрямовано на введення в ході процесу твердих сировинних матеріалів, які включають металовмісний матеріал і вуглецевий матеріал, в місткість прямого плавлення у відносно малу ділянку в шарі металу у ванні розплаву в місткості для суттєвого піднімання розплавленого матеріалу і газу з шару металу у ділянку в місткості, яка розташована над ванною розплаву. Зокрема, винахід вводить тверді сировинні матеріали з достатньою кількістю руху і/або швидкістю через пару протилежних наконечників, які орієнтовані в місткості і встановлені для формування перехресних факелів матеріалу, що вводиться у ванну розплаву.
