METHOD FOR MAKING STEEL IN A CONVERTER

FIELD: ferrous metallurgy, steel making. SUBSTANCE: 0.2 to 2.0 l of kerosene per ton of scrap is sprayed in scoop filled with the scrap before scrap entering converter. Once the kerosene has burnt, filling cast iron into the converter is carried out. Scrap spraying by kerosene leads to snow and ice...

Beschreibung
Zusammenfassung:	FIELD: ferrous metallurgy, steel making. SUBSTANCE: 0.2 to 2.0 l of kerosene per ton of scrap is sprayed in scoop filled with the scrap before scrap entering converter. Once the kerosene has burnt, filling cast iron into the converter is carried out. Scrap spraying by kerosene leads to snow and ice separation from the scrap, that prevents exhausts from the converter. EFFECT: increased output of the steel at the expense of prevention of exhausts from the converter resulted from moisture in the form of snow and ice. 1 tbl Изобретение относится к черной металлургии, конкретно к способам производства стали в сталеплавильных агрегатах, например кислородных конверторах. Цель изобретения - увеличение выхода стали за счет предотвращения выбросов из конвертора при попадании влаги в виде снега и льда. Перед завалкой лома в конвертор лом в совке опрыскивают керосином в количестве 0,2 - 2,0 л на 1 т лома, при этом заливку чугуна в конвертор производят после сгорания керосина. Опрыскивание керосином лома приводит к отслаиванию снега и льда от лома, что предотвращает выбросы из конвертора. 1 табл.
