Description
(54) СПОСОБ ПОЛУЧЕНИЯ АЛЮМИНИЕВОГО ЧУГУНА(54) METHOD OF OBTAINING ALUMINUM CAST IRON
1one
Изобретение относитс к литейному производству , в частности к способу получени алюминиевого чугуна.The invention relates to foundry, in particular, to a method for producing aluminum cast iron.
Известен способ получени алюминиевого чугуна путем расплавлени исходного чуГуна и смещени его с алюминием под шлаком .A method of producing aluminum cast iron is known by melting the original pig iron and displacing it with aluminum under the slag.
Однако получаемый алюминиевый чугун имеет невысокие мехшшческие свойства и жидкотекучесть. Угар алюмини высокий и составл ет 50%,However, the resulting aluminum cast iron has low mechanical properties and fluidity. Aluminum fences are high and 50%
Цель изобретени - повышение качества металла и. уменьшение угара алюмини - достигаетс тем, что в чугун вместе с алюминием ввод т литий в количестве О,1-0,5% от веса чугуна при 128О-135О С,The purpose of the invention is to improve the quality of the metal and. reduction of aluminum burns - is achieved by the fact that lithium in the amount of O is introduced into the cast iron together with aluminum, 1-0.5% of the weight of cast iron at 128 ° -135 ° C,
При разливке алюминиевого чугуна литий горит на струе чугуна, предохран тем самым алюминий от окислени . Образующиес при окислении лити соединени удалшотс в шлак.When casting aluminum iron, lithium burns on a jet of iron, thereby protecting aluminum from oxidation. The compounds formed during the oxidation of lithium are removed into slag.
Литий может быть введен в расплав в чистом виде или в виде сплавов его с алюминием при температуре чугуна не выше 1370°С.Lithium can be introduced into the melt in pure form or in the form of its alloys with aluminum at a cast iron temperature not higher than 1370 ° C.
