Description
Изобретение относнтс к литейному производству , в частности к способам модифицировани чугуна.The invention relates to foundry, in particular, to methods for modifying cast iron.
Известен способ модифицировани чугуна, ио которому в чугун ввод т ферромарганец.There is a known method for modifying cast iron, to which ferromanganese is introduced into cast iron.
Введение ферромарганца в чугун способствует повышению плотности тонкостенных отливок из высокоуглеродистого и высококремиистого чугуиов, новыша их герметичность, но снижает пластичность. Кроме того, введение ферромарганца в чугун вызывает необходимость его перегрева.The introduction of ferromanganese into cast iron contributes to an increase in the density of thin-walled castings of high-carbon and high-grade chugui, and their tightness, but reduces ductility. In addition, the introduction of ferromanganese in the cast iron necessitates its overheating.
Дл повышени пластичности , снижени СКЛ01ПТОСТИ к отбеливанию предложено в качестве марганецсодержащей добавки в чугун вводить марганцевую руду в количестве 0,2-0,6% от веса металла.In order to increase plasticity, decrease SKL01POSTOST to bleaching, it was proposed to introduce manganese ore as an manganese additive in cast iron in an amount of 0.2-0.6% by weight of the metal.
Опробовали марганцевые руды различного сорта и установили, что в качестве модификатора могут быть исиользоваиы руды со следую1дими колебани ми пределов, вход щих в их состав компонептов (в вес. %):We tried various types of manganese ores and found that, as a modifier, can be used ores with the following variations in the limits of their composition (in wt.%):
20,0-53.0 6,0-38,0 2,0-11,0 1,0-3,0 Остальное20.0-53.0 6.0-38.0 2.0-11.0 1.0-3.0 Else
