Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления тепловых агрегатов, печей, электрических плит.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of thermal units, furnaces, electric stoves.
Известен чугун, содержащий, мас.%: углерод 1,5-4,0; кремний 1,5-6,0; марганец 0-3,0; алюминий 0-2,0; титан 0-2,0; олово 0-2,5; хром 0-3,0; ниобий 0-5,0; молибден 0-5,0; кобальт 0-3,5; вольфрам 0-5,0; железо и примеси - остальное [1].Known cast iron, containing, wt.%: Carbon 1.5-4.0; silicon 1.5-6.0; manganese 0-3.0; aluminum 0-2.0; titanium 0-2.0; tin 0-2.5; chrome 0-3.0; niobium 0-5.0; molybdenum 0-5.0; cobalt 0-3.5; tungsten 0-5.0; iron and impurities - the rest [1].
Задачей изобретения является повышение термостойкости чугуна.The objective of the invention is to increase the heat resistance of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, алюминий, титан, олово, хром, ниобий, молибден, кобальт, вольфрам, железо, дополнительно содержит кадмий, цинк и бор, при следующем соотношении компонентов, мас.%: углерод 3,2-3,7; кремний 1,8-2,2; марганец 0,8-1,2; алюминий 0,1-0,3; титан 0,1-0,15; олово 0,001-0,003; хром 1,5-2,5; ниобий 0,2-0,4; молибден 0,7-1,1; кобальт 0,3-0,5; вольфрам 2,0-2,5; кадмий 0,01-0,03; цинк 0,03-0,09; бор 0,06-0,11; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, titanium, tin, chromium, niobium, molybdenum, cobalt, tungsten, iron, additionally contains cadmium, zinc and boron, in the following ratio, wt.%: carbon 3.2-3.7; silicon 1.8-2.2; manganese 0.8-1.2; aluminum 0.1-0.3; titanium 0.1-0.15; tin 0.001-0.003; chrome 1.5-2.5; niobium 0.2-0.4; molybdenum 0.7-1.1; cobalt 0.3-0.5; tungsten 2.0-2.5; cadmium 0.01-0.03; zinc 0.03-0.09; boron 0.06-0.11; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В чугуне выделения графита имеют пластинчатую форму благодаря присутствию титана, олова, алюминия, свинца. Кальций раскисляет чугун. Хром и бор стабилизируют карбиды. Ниобий упрочняет твердый раствор. Титан предотвращает появление отбеленных участков, а также образует карбонитриды, придающие мелкозернистость структуре чугуна. Совместное присутствие в составе чугуна хрома, молибдена, кобальта, вольфрама способствует образованию структуры мелкоигольчатого мартенсита и повышению сопротивления чугуна деформациям при высоких температурах.In cast iron, graphite emissions are lamellar due to the presence of titanium, tin, aluminum, and lead. Calcium deoxidizes cast iron. Chrome and boron stabilize carbides. Niobium strengthens the solid solution. Titanium prevents the appearance of bleached areas, and also forms carbonitrides, which give a fine-grained structure to cast iron. The joint presence of chromium, molybdenum, cobalt, and tungsten in the composition of cast iron contributes to the formation of the structure of fine-needle martensite and to an increase in the resistance of cast iron to deformations at high temperatures.
Чугун выплавляют в вагранках, дуплекс-процессом или в электропечах и отливают в песчаные формы. Температура расплава при заливке литейных форм должна быть не ниже 1330°С. Отливки подвергают отжигу при температуре 500-550°С для снятия внутренних напряжений.Cast iron is smelted in cupolas, a duplex process or in electric furnaces and cast in sand forms. The temperature of the melt when casting molds should be at least 1330 ° C. Castings are annealed at a temperature of 500-550 ° C to relieve internal stresses.
