The goal is to increase the yield due to the stabilization of the properties and structure of the resulting castings. The magnesium-containing wire is introduced into the melt of the metal receiver, the cyclic portion of gray iron is poured into the metal receiver, and the iron is forced out of it into the mold. The wire is introduced at a rate dependent on the consumption of magnesium, the mass of magnesium in the wire, and the time between feed cycles of the pig iron. As a result, the metal is saturated with magnesium to an initially predetermined level, which makes it possible to increase the uniformity of the magnesium content in the castings and to achieve the same strength properties. 1 tab.
Description
Изобретение относитс к металлургии , в частности к литейному производству , и касаетс конвейерного производства заготовок из чугуна.The invention relates to metallurgy, in particular to foundry, and relates to the conveyor production of pig iron.
Цель изобретени - повьшение выхода годного за счет стабилизации свойств и структуры получаемых отливок .The purpose of the invention is to increase the yield due to the stabilization of the properties and structure of the obtained castings.
Сущность предлагаемого способа заключаетс в следующем.The essence of the proposed method is as follows.
Между миксером с металлом, например .магнитодинамическим насосом (МДН) и конвейером с литейными формами, размещают металлоприемник. Из ОДН заполн ют металлоприемник заданным количеством серого чугуна. В расплав металлоприемника ввод т магнийсодержащую проволоку до получений в чугуне заданного содержани магни . Затем порцию серого чугуна из МДН заливают в металлоприемник, вытесн из него магниевый чугун в литейную форму. После этого в металлоприемник ввод т порошковую проволоку в течение времени и со скоростью, которые обеспечивают насыщение металла магнием до первона чально заданного уровн . Снова из МДН заливают в металлоприемник серый чугун, вытесн магниевый в форму.Between the mixer with the metal, for example. Magnetodynamic pump (MDN) and the conveyor with the molds, place the metal receivers. Of the ODNs, the metal receiver is filled with a predetermined amount of gray iron. The magnesium-containing wire is injected into the molten metal receiver until the specified magnesium content is obtained in the iron. Then a portion of gray iron from MDN is poured into the metal receiver, and the magnesium cast iron is forced out of it into the mold. After that, the flux-cored wire is introduced into the metal receiver over time and at a rate that ensures the saturation of the metal with magnesium to the initially specified level. Again, gray cast iron was poured from the MDN into the metal receiver, and magnesium was forced into the mold.

рование шаровидного графита в нем, выбирают в зависимости от массы обрабатываемого чугуна, содержани в расплаве серы, газов, температуры металла, степени угара магни , скорости охлаждени и других факторов.The use of nodular graphite in it is chosen depending on the weight of the pig iron being treated, the content of sulfur in the melt, gases, the metal temperature, the degree of magnesium fusion, the cooling rate, and other factors.
При обработке чугуна магниевой проволокой масса введенного в расплав магни определ етс содержанием магни в проволоке, временем и скоростью ее ввода, т.е. , кг. Выбрав врем между заливкой двух форм С , зна содержание магни в проволоке и определив по известной завй- синост Q, наход т When the cast iron is processed with magnesium wire, the mass of magnesium introduced into the melt is determined by the magnesium content in the wire, the time and speed of its introduction , kg Choosing the time between the pouring of two forms C, knowing the content of magnesium in the wire and determining from a known quantity Q, we find

Повьшение выхода годного по пред- лагаемому способу достигаетс за счет стабилизации прочностных свойств и структуры получаемых отливок на прот жении всего цикла лить .The yield increase according to the proposed method is achieved by stabilizing the strength properties and structure of the castings obtained throughout the entire casting cycle.
Как следует из таблицы, предлагаемый способ позвол ет повысить выход годного за счет повышени однородности содержани магни в отливках и однородности прочностных свойств.As follows from the table, the proposed method allows to increase the yield by increasing the uniformity of the magnesium content in the castings and the uniformity of the strength properties.
