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 для серого чугуна, содержащий, мас.%: кремний 70,0-80,0; кальций до 0,8; стронций 0,5-2,0; РЗМ до 0,8; железо - остальное [1].Known modifier for gray cast iron, containing, wt.%: Silicon 70.0-80.0; calcium up to 0.8; strontium 0.5-2.0; REM up to 0.8; iron - the rest [1].
Задача изобретения состоит в снижении расхода модификатора.The objective of the invention is to reduce the consumption of modifier.
Технический результат достигается тем, что модификатор для серого чугуна, содержащий кремний, кальций, стронций, РЗМ, железо, дополнительно включает алюминий и серебро при следующем соотношении компонентов, мас.%: кремний 60,0-65,0; кальций 1,0-1,5; стронций 1,0-1,5; РЗМ 1,0-1,5; алюминий 10,0-15,0; серебро 1,0-1,5; железо - остальное.The technical result is achieved by the fact that the modifier for gray cast iron containing silicon, calcium, strontium, rare-earth metals, iron, additionally includes aluminum and silver in the following ratio of components, wt.%: Silicon 60.0-65.0; calcium 1.0-1.5; strontium 1.0-1.5; REM 1.0-1.5; aluminum 10.0-15.0; silver 1.0-1.5; iron is the rest.
В таблице приведены составы модификатора для серого чугуна.The table shows the modifier compositions for gray cast iron.
Введенные в серый чугун компоненты, входящие в состав модификатора, проявляют себя следующим образом. Кремний способствует выделению графита, несколько повышает механические свойства чугуна. Кальций, алюминий и РЗМ раскисляют чугун. Серебро способствует получению мелкозернистой структуры сплава. Стронций уменьшает количество газовых включений в чугуне.The components included in the gray cast iron, which are part of the modifier, manifest themselves as follows. Silicon promotes the release of graphite, slightly increases the mechanical properties of cast iron. Calcium, aluminum and rare-earth metals deoxidize cast iron. Silver contributes to obtaining a fine-grained alloy structure. Strontium reduces the amount of gas inclusions in cast iron.
Серый чугун, например, следующего состава, мас.%: углерод 2,9; кремний 1,2; марганец 0,6; алюминий 0,005; ванадий 0,96; сера 0,18; фосфор 0,18; хром 0,08; железо - остальное, имеет прочность 530 МПа. Обработка его модификатором (при расходе 0,6-0,7% от массы чугуна) позволит повысить прочность сплава до 550-560 МПа.Gray cast iron, for example, of the following composition, wt.%: Carbon 2.9; silicon 1,2; manganese 0.6; aluminum 0.005; vanadium 0.96; sulfur 0.18; phosphorus 0.18; chromium 0.08; iron - the rest, has a strength of 530 MPa. Processing it with a modifier (at a rate of 0.6-0.7% by weight of cast iron) will increase the strength of the alloy to 550-560 MPa.
Модификатор вводят в расплав серого чугуна в желобе вагранки или в ковше. Оптимальное время выдержки модифицированного чугуна в ковше при массе жидкого расплава в нем до 0,5 т - 3-5 мин; 0,5-2 т - 5-8 мин; 5-8 т - 5-10 мин.The modifier is introduced into the molten gray iron in the cupola of the cupola or in the bucket. The optimal exposure time of modified cast iron in the ladle with a mass of liquid melt in it up to 0.5 t is 3-5 minutes; 0.5-2 t - 5-8 min; 5-8 t - 5-10 min.
