Description
Изобретение относитс к области изыскани чугунов, примен емых дл ответственных деталей двигателей, например головки цилиндров .The invention relates to the field of exploration of cast irons used for critical engine parts, such as cylinder heads.
Известен чугун, содержащий углерод, кремний , марганец, серу и железо.Known cast iron containing carbon, silicon, manganese, sulfur and iron.
Чугун предлагаемого состава имеет значительно повышенную термическую стойкость 60-80 циклов (нагрев до 600°С и охлаждени в воду до по влени первой трещины).Cast iron of the proposed composition has a significantly increased thermal resistance of 60-80 cycles (heating to 600 ° C and cooling in water until the appearance of the first crack).
Твердость чугуна находитс в пределах НВ 187-229.The hardness of the iron is within HB 187-229.
Дл повышени термостойкости в чугун ввод т медь, при следующем содержании компонентов , %:To increase the heat resistance, copper is introduced into the iron, with the following content of components,%:
3,4-3,65 1,6-1,9 0,85-1,05 0,15-0,25 0,06-0,2 до 0,12 до 0,12 до 0,12 остальное3.4-3.65 1.6-1.9 0.85-1.05 0.15-0.25 0.06-0.2 to 0.12 to 0.12 to 0.12 the rest
Указанна композици чугуна обеспечивает формирование равномерно распределенного крупнопластинчатого среднезавихренного графита , расчлен ющего металлическую основу на отдельные элементы и образующего своеобразные термокомпенсационные щвы. Чугун обладает высокой жидкотекучестью, хорошей заполн емостью формы и малой склонностью к образованию усадочных дефектов.The above composition of cast iron provides for the formation of a uniformly distributed large-plate medium-fluxed graphite, which breaks down the metal base into separate elements and forms a kind of thermal compensating grooves. Cast iron has a high fluidity, good filling capacity of the form and a small tendency to the formation of shrinkage defects.
