Abstract
Description
Изобретение относится к области металлургии, в частности к составам модификаторов, используемых в производстве серого чугуна.The invention relates to the field of metallurgy, in particular to the compositions of modifiers used in the production of gray cast iron.
Известен модификатор, содержащий, мас.%: кремний 6,5-12,0; углерод 2,0-3,0; марганец 0,1-1,0; церий 0,2-2,0; бор 0,1-1,0; железо - остальное [1].Known modifier containing, wt.%: Silicon 6.5-12.0; carbon 2.0-3.0; manganese 0.1-1.0; cerium 0.2-2.0; boron 0.1-1.0; iron - the rest [1].
Задача изобретения состоит в повышении прочности серого чугуна, обработанного модификатором.The objective of the invention is to increase the strength of gray cast iron treated with a modifier.
Технический результат достигается тем, что модификатор для обработки серого чугуна, содержащий кремний, углерод, марганец, церий, бор, железо, дополнительно включает азот и никель, при следующем соотношении компонентов, мас.%: кремний 10,0-12,0; углерод 2,0-3,0; марганец 0,5-1,0; церий 3,0-4,0; бор 2,0-3,0; азот 0,002-0,003; никель 18,0-20,0; железо - остальное.The technical result is achieved in that the modifier for processing gray cast iron, containing silicon, carbon, manganese, cerium, boron, iron, additionally includes nitrogen and nickel, in the following ratio, wt.%: Silicon 10.0-12.0; carbon 2.0-3.0; manganese 0.5-1.0; cerium 3.0-4.0; boron 2.0-3.0; nitrogen 0.002-0.003; nickel 18.0-20.0; iron is the rest.
В таблице 1 приведены составы модификатора, в таблице 2 - прочность серого чугуна, обработанного модификатором (расход модификатора 1,8-2,0% от массы выплавляемого чугуна).Table 1 shows the modifier compositions, table 2 shows the strength of gray cast iron treated with a modifier (modifier consumption 1.8–2.0% of the mass of cast iron).
Введенные в чугун компоненты, входящие в состав модификатора, проявляют себя следующим образом. Кремний способствует выделению графита. Бор стабилизирует карбиды. Никель упрочняет твердый раствор. Церий выполняет функцию раскислителя. Азот обеспечивает мелкозернистость структуры чугуна.The components included in the cast iron, which are part of the modifier, manifest themselves as follows. Silicon promotes the release of graphite. Boron stabilizes carbides. Nickel hardens the solid solution. Cerium acts as a deoxidizing agent. Nitrogen provides a fine grain structure of cast iron.
Модификатор в нагретом не ниже 120°С состоянии вводят в расплав чугуна в ковше. Оптимальное время выдержки модифицированного чугуна в ковше 5-8 мин.The modifier in a heated condition not lower than 120 ° C is introduced into the molten iron in the ladle. The optimum exposure time of modified cast iron in the ladle is 5-8 minutes.
