Description
СОСТАВ БРИКЕТА ДЛЯ МОДИФИЦИРОВАНИЯ ЧУГУИАCOMPOSITION OF BRIQUETTES FOR MODIFICATION OF CHUGUIA
Известны составы брикетов дл обработки расплавленного чугуна с целью получени графита с шаровидной формой, включающие в себ металлический магний и железистую составл ющую в виде, например, металлической стружки.Briquette compositions are known for treating molten iron to obtain graphite with a spherical shape, including metallic magnesium and a ferrous component in the form of, for example, metal chips.
Предлагаемый состав отличаетс тем, что дл спокойного протекани процесса в качестве железосодержащей добавки введено губчатое железо, которое с одной стороны весьма чисто по примес м, в частности по такой вредной примеси, как сера, с другой же стороны пористо .The proposed composition is characterized by the fact that sponge iron was introduced as an iron-containing additive for a smooth process, which on the one hand is very pure in impurities, in particular in such a harmful impurity as sulfur, on the other hand porous.
При подаче в расплавленный чугун брикетов , состо щих из металлического магни и губчатого железа, вследствие пористости последнего происходит постепенное прогревание иWhen briquettes consisting of metallic magnesium and spongy iron are fed to the molten iron, the latter is gradually heated and
испарение металлического магни , который выдел етс в металл через поры, происходит повыщение процента его усвоени . Рекомендуетс вводить в смесь 4-40% металлического магни , предпочтительно 5-25%. Желательно примен ть брикеты, имеюнще плотность 2- 4 г/смз.Evaporation of metallic magnesium, which is released into the metal through the pores, increases the percentage of its absorption. It is recommended that 4-40% of metallic magnesium be introduced into the mixture, preferably 5-25%. It is advisable to use briquettes having a density of 2-4 g / cm3.
Предмет изобретени Subject invention
Состав брикета дл модифицировани чугуна , включающий магний и железосодержащую добавку, отличающийс тем, что, с целью спокойного протекани процесса, в его состав в качестве железосодержащей добавки введено губчатое железо.The composition of the briquette for modifying the cast iron, including magnesium and an iron-containing additive, is characterized in that sponge iron is introduced into its composition as an iron-containing additive in order to ensure a smooth process.
