Изобретение относитс к литейному производству , в частности, к модифицированию чугуна .The invention relates to foundry, in particular, to the modification of cast iron.
Дл модифицировани чугунов, с целью сокращени ци.кла те1рмичес1кой обработки и предотвращени выделени свободного углерода в период первичной кристаллизации, а также повышени механических свойств, широкое применение получила обработка его висмутом, например, в составе комплексного модификатора , представл ющего собой механическую смесь, состо щую «з алюмини , бора и металлического висмута при следующем соотнок ении компонентов (в %)In order to modify cast irons, in order to reduce the heat cycle of the thermal treatment and to prevent the release of free carbon during the initial crystallization, as well as to improve the mechanical properties, its treatment with bismuth has been widely used, for example, as part of a complex modifier consisting of a mechanical mixture "From aluminum, boron and metallic bismuth with the following ratio of components (in%)

В0,001-0,006V0.001-0,006
Bi0,001-0,02Bi0.001-0.02
от веса жидкого металла.by weight of liquid metal.
Обработка таким комплексным модификатором имеет существенный недостаток: в процессе модифицировани чугуна имеет место большой угар (до 70%) дорогосто щего и дефицитного висмута. Это объ сн етс гем, что температура выпущенного из электропечи чугуна приближаетс к температуре парообразовани чистого вИОмута (1560°С).The treatment with such a complex modifier has a significant drawback: in the process of modifying the cast iron, there is a large waste (up to 70%) of expensive and scarce bismuth. This is explained by the heme that the temperature of the cast iron released from the electric furnace approaches the temperature of vaporization of the pure oil (1560 ° C).
Целью изобретени вл етс устранение указанного недостатка, дл чего висмут ввод т в металл в виде сплава с марганцем, который может быть получен, например, путем сплавлени высокопроцентного ферромарганца или марганца (90-99%) и металлического висмута (1 -10%).The aim of the invention is to eliminate this drawback, for which bismuth is introduced into the metal as an alloy with manganese, which can be obtained, for example, by fusing high-percentage ferromanganese or manganese (90-99%) and metallic bismuth (1-10%).
Испытани показали, что введение висмута в виде сплава с марганцем в качестве модификатора позволило уменьшить угар висмута до 30%, а, следовательно, « его расходTests have shown that the introduction of bismuth in the form of an alloy with manganese as a modifier made it possible to reduce the loss of bismuth to 30%, and, consequently, "its consumption
Марганцево-висмутовый сплав может вводитьс в металл в комплексе с различными модификаторами, в частности с алюминием и бором при следующем соотнощении компонентов (в %):The manganese-bismuth alloy can be introduced into the metal in a complex with various modifiers, in particular with aluminum and boron, at the following ratio of components (in%):

Предмет изобретени Subject invention
Способ обработки чугуна висмутом путем введени последнего в расплав, отличающийс тем, что, с целью увеличени процента усвоени висмута, его ввод т в чугун в виде сплава с марганцем.The method of treating pig iron with bismuth by introducing the latter into the melt, characterized in that, in order to increase the percentage of bismuth uptake, it is introduced into the iron as an alloy with manganese.
