Изобретение относитс к металлургии и, в частности, к разливке стали и сплавов.This invention relates to metallurgy and, in particular, to casting steel and alloys.
Известен шлак дл разливки стали и сплавов, содержащий окислы натри и кали двуокись титана, кремнезем и фтористыйKnown slag for casting steel and alloys containing oxides of sodium and potassium titanium dioxide, silica and fluoride.
натрий.sodium.
Известный шлак с низкой температурой плавлени (5ОО-800 С) при минимальном дымовыделении хорошо поглошает и раствор ет в себе образующиес окислы железа, алюмини , хрома и др.The known slag with a low melting point (5OO-800 C) with a minimum smoke emission absorbs well and dissolves in itself the formed oxides of iron, aluminum, chromium, etc.
Однако в слитках, отлитых под слоем этого шлака,- наблюдаетс тенденци перехода бора из шлака в металл, что дл н&которых марок сталей нежелательно.However, in ingots cast under a layer of this slag, a tendency is observed for the transition of boron from slag to metal, which is undesirable for n &
Цель изобретение-снижение температуры плавлени , уменьшение дымовыделени и улучшени качества поверхности слитковдостигаетс тем, что компоненты шлака saты в следующем соотношении (вес.%):The purpose of the invention is to reduce the melting temperature, reduce the smoke emission and improve the quality of the ingot surface is achieved by the fact that the slag components are in the following ratio (wt.%):
Окись натри -окись кали 1О-45 Двуокись титана5-25Sodium oxide - potassium oxide 1О-45 Titanium dioxide 5-25
Кремнезем25-50Silica 25-50
Фтористый натрий3-15Sodium fluoride 3-15
Предлагаемый шлак выплавл ют к дуговых печах с углеродистой (глафитовой) футеровкой или водоохлаждаемым металлическим тиглем, в Печах сопротивлени , в пламенных печах, нааример, используемых при производстве стекла.The proposed slag is smelted to arc furnaces with carbonaceous (glafit) lining or a water-cooled metal crucible, in resistance furnaces, in fiery furnaces, used in glass production.
В дроб енQM виде или отдельными кусками шлак ввод т в изложницу или кристаллизатор до или в процессе разливки из расчета 2-6 кг на 1 т металла.Slag is introduced into the QM fraction in the form or individual pieces into the mold or mold before or during casting at the rate of 2-6 kg per 1 ton of metal.
При разливке сталей шлак быстро расплавл етс - теплом 11|еталла с образованием жидкого сло , дымо.)выдёление при разливке практически отсутствует, слитки имеют глакую бездефектную поверхность.When casting steel, slag quickly melts - with heat 11 | metal with the formation of a liquid layer, smoke.) There is practically no ejection during casting, ingots have a non-defective surface.
Шлак можно примен ть при сифонной и верховой разливке стали и сплавов в изложницы , а также при непрерывной и полунепрерывной разливке.Slag can be used in siphon and top casting of steel and alloys into molds, as well as in continuous and semi-continuous casting.
