Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам чугуна, который может быть использован для изготовления деталей тепловых агрегатов, металлургического оборудования и других изделий, работающих в условиях повышенных термоциклических нагрузок.The invention relates to the field of ferrous metallurgy, and in particular to compositions of cast iron, which can be used for the manufacture of parts of thermal units, metallurgical equipment and other products operating under high thermal cyclic loads.
Известен чугун, содержащий, мас.%: углерод 2,5-4,0; кремний 0,5-3,5; марганец 0,2-1,5; хром 0-3,0; титан ≤2,0; бор ≤2,0; ванадий ≤2,0; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 2.5-4.0; silicon 0.5-3.5; manganese 0.2-1.5; chrome 0-3.0; titanium ≤2.0; boron ≤2.0; vanadium ≤2.0; iron - 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, хром, титан, бор, ванадий, железо, дополнительно включает барий, при следующем соотношении компонентов, мас.%: углерод 3,6-4,2; кремний 0,8-1,2; марганец 0,8-1,2; хром 0,3-0,8; титан 1,0-1,5; бор 0,01-0,03; ванадий 1,0-1,5; барий 0,001-0,002; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, chromium, titanium, boron, vanadium, iron, additionally includes barium, in the following ratio, wt.%: Carbon 3,6-4,2; silicon 0.8-1.2; manganese 0.8-1.2; chrome 0.3-0.8; titanium 1.0-1.5; boron 0.01-0.03; vanadium 1.0-1.5; barium 0.001-0.002; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение термостойкости чугуна достигается за счет комплексного влияния компонентов, входящих в его состав. Хром и бор стабилизируют карбиды. Ванадий упрочняет твердый раствор. Барий раскисляет чугун. Титан способствует измельчению зерна.Increasing the heat resistance of cast iron is achieved due to the complex effect of the components that make up its composition. Chrome and boron stabilize carbides. Vanadium strengthens the solid solution. Barium deoxidizes cast iron. Titanium helps to chop grain.
Чугун выплавляют в вагранках, дуплекс-процессом или в электропечах и отливают в горячие (400-500°С) металлические формы, обмазанные огнеупорной глиной. Отливки подвергают отжигу при температуре 900-980°С с последующим охлаждением с печью.Cast iron is smelted in cupola furnaces, by a duplex process or in electric furnaces, and cast into hot (400-500 ° C) metal molds coated with refractory clay. The castings are annealed at a temperature of 900-980 ° C, followed by cooling with a furnace.
