Abstract
Description
Изобретение относится к области металлургии, а именно к составам лигатуры, которая может быть использована при выплавке углеродистой стали.The invention relates to the field of metallurgy, and in particular to compositions of the ligature, which can be used in the smelting of carbon steel.
Известна лигатура, содержащая, мас.%: кремний 17,0-34,0; марганец 50,0-75,0, бор 0,1-3,0; азот 0,03-3,0; железо остальное [1]. Расход такой лигатуры 1,2% от массы стали.Known ligature, containing, wt.%: Silicon 17.0-34.0; manganese 50.0-75.0, boron 0.1-3.0; nitrogen 0.03-3.0; iron the rest [1]. The consumption of such a ligature is 1.2% by weight of steel.
Задачей изобретения является снижение расхода лигатуры.The objective of the invention is to reduce the consumption of ligatures.
Технический результат достигается тем, что лигатура для углеродистой стали, содержащая кремний, марганец, бор, железо, дополнительно содержит вольфрам и медь при следующем соотношении компонентов, мас.%: кремний 20,0-30,0; марганец 35,0-40,0; бор 1,0-1,5; вольфрам 10,0-15,0; медь 10,0-15,0; железо остальное.The technical result is achieved by the fact that the ligature for carbon steel containing silicon, manganese, boron, iron, additionally contains tungsten and copper in the following ratio of components, wt.%: Silicon 20.0-30.0; manganese 35.0-40.0; boron 1.0-1.5; tungsten 10.0-15.0; copper 10.0-15.0; iron the rest.
В таблице приведены составы лигатуры для углеродистой стали.The table shows the ligature compositions for carbon steel.
Введение лигатуры в количестве 0,9-1% повышает прочность углеродистой стали до 10%. Кремний способствует уменьшению усадки сплава, несколько увеличивает прочность. Марганец способствует повышению прочности стали, снижая ее пластичность и вязкость. Бор стабилизирует карбиды. Медь препятствует образованию трещин, увеличивает жидкотекучесть сплава. Медь и вольфрам способствуют повышению прочности и твердости углеродистой стали.The introduction of ligatures in an amount of 0.9-1% increases the strength of carbon steel up to 10%. Silicon helps reduce shrinkage of the alloy, slightly increases strength. Manganese helps to increase the strength of steel, reducing its ductility and toughness. Boron stabilizes carbides. Copper prevents the formation of cracks, increases the fluidity of the alloy. Copper and tungsten increase the strength and hardness of carbon steel.
Лигатура может быть выплавлена, например, в индукционных электропечах (ИСТ-0,06, ИСТ-0,16 и др.). Основное сырье для выплавки: ферромарганец (ФМн75, ФМн78); силикомарганец (СМн26), ферробор (ФБ1, ФБ2, ФБ3); ферровольфрам (В1); медь (М3, М4).Ligature can be melted, for example, in induction furnaces (IST-0.06, IST-0.16, etc.). The main raw materials for smelting: ferromanganese (FMn75, FMn78); silicomanganese (СМн26), ferroboron (ФБ1, ФБ2, ФБ3); ferro-tungsten (B1); copper (M3, M4).
Лигатуру (в нагретом до 150-170°C состоянии) вводят в печь за 15-20 минут до выпуска стали.The ligature (in a state heated to 150-170 ° C) is introduced into the furnace 15-20 minutes before the steel is released.
