Abstract
Description
Изобретение относится к области металлургии, в частности к составам модификаторов, используемых в производстве чугуна.The invention relates to the field of metallurgy, in particular to the compositions of modifiers used in the production of 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 чугуна, обработанного модификатором.The objective of the invention is to increase the strength of cast iron treated with a modifier.
Технический результат достигается тем, что модификатор для обработки чугуна, содержащий кремний, углерод, марганец, церий, бор и железо, дополнительно содержит молибден, кальций и цирконий при следующем соотношении компонентов, мас.%: кремний 5,0-7,0; углерод 2,0-3,0; марганец 0,5-1,5; церий 1,0-2,0; бор 0,5-1,0; молибден 10,0-15,0; кальций 0,3-0,5; цирконий 5,0-8,0; железо - остальное.The technical result is achieved by the fact that the modifier for cast iron processing, containing silicon, carbon, manganese, cerium, boron and iron, additionally contains molybdenum, calcium and zirconium in the following ratio of components, wt.%: Silicon 5.0-7.0; carbon 2.0-3.0; manganese 0.5-1.5; cerium 1.0-2.0; boron 0.5-1.0; molybdenum 10.0-15.0; calcium 0.3-0.5; zirconium 5.0-8.0; iron is the rest.
В таблице 1 приведены составы модификатора, в таблице 2 - прочность чугуна, обработанного модификатором (расход модификатора 2,0-2,5% от массы выплавляемого чугуна).Table 1 shows the composition of the modifier, in table 2 - the strength of cast iron treated with a modifier (modifier consumption of 2.0-2.5% by weight of cast iron).
Введенные в чугун компоненты, входящие в состав модификатора, проявляют себя следующим образом. Кремний способствует выделению графита. Бор стабилизирует карбиды. Молибден упрочняет твердый раствор. Цирконий способствует измельчению зерна. Церий и кальций выполняют функцию раскислителей.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. Molybdenum strengthens the solid solution. Zirconium contributes to grain refinement. Cerium and calcium act as deoxidizers.
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.
