Abstract

Описаний спосіб запуску процесу плавлення металовмісного матеріалу. Спосіб включає використання теплового потоку водоохолоджуваних елементів в нижніх частинах плавильної посудини для забезпечення індикації температури ванни розплаву під час щонайменше ранньої стадії способу запуску і регулювання швидкостей впорскування кисневмісного газу та/або вуглецевого матеріалу в плавильну посудину для регулювання температури ванни розплаву під час запуску для запобігання перевищенню критичних рівнів теплового потоку і зупинки способу запуску.
