Description
Изобретение относится к области металлургии, в частности к составам чугуна», который может быть использован для изготовления частей топок, деталей цементных печей, конфорок газовых и электроплит.The invention relates to the field of metallurgy, in particular to compositions of cast iron ", which can be used for the manufacture of parts of furnaces, parts of cement furnaces, gas burners and electric stoves.
Известен чугун, содержащий, мас.%: углерод 1,7-3,8; кремний 0,01-2,5; марганец 0,01-1,0; алюминий 0,01-1,0; никель 0,01-5,0; ванадий 0,001-1,0; медь 0-0,2; кобальт 0,01-5,0; бериллий 0,01-0,2; железо - остальное [1].Known cast iron, containing, wt.%: Carbon 1.7-3.8; silicon 0.01-2.5; manganese 0.01-1.0; aluminum 0.01-1.0; nickel 0.01-5.0; vanadium 0.001-1.0; copper 0-0.2; cobalt 0.01-5.0; beryllium 0.01-0.2; iron - the rest [1].
Задачей изобретения является повышение термостойкости и окалиностойкости чугунаThe objective of the invention is to increase the heat resistance and scale resistance of cast iron
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, алюминий, никель, ванадий, медь, кобальт, бериллий, железо, дополнительно включает РЗМ и рений, при следующем соотношении компонентов, мас.%: углерод 2,7-3,3, кремний 1,7-2,3; марганец 2,0-3,0; алюминий 2,0-2,5, никель 3,0-3,5; ванадий 1,0-1,5; медь 0,6-1,2; кобальт 0,6-1,2; бериллий 0,001-0,002; РЗМ 0,1-0,2; рений 0,6-1,2; железо - остальное.The technical result is achieved by the fact that cast iron containing carbon, silicon, manganese, aluminum, nickel, vanadium, copper, cobalt, beryllium, iron, additionally includes rare-earth metals and rhenium, with the following ratio of components, wt.%: Carbon 2.7-3 3, silicon 1.7-2.3; manganese 2.0-3.0; aluminum 2.0-2.5; nickel 3.0-3.5; vanadium 1.0-1.5; copper 0.6-1.2; cobalt 0.6-1.2; beryllium 0.001-0.002; REM 0.1-0.2; rhenium 0.6-1.2; iron is the rest.

В составе чугуна компоненты проявляют себя следующим образом. Медь способствует графитизации, появлению перлита, повышает прочность и пластичность сплава. Ванадий повышает вязкость и пластичность чугуна, улучшает его структуру. Кобальт и никель увеличивают твердость и прочность сплава. Рений увеличивает твердость и работоспособность чугуна при высоких температурах, ухудшает свариваемость. Алюминий тормозит рост окалины. РЗМ раскисляют чугун. Бериллий способствует измельчению зерна.In the composition of cast iron, the components manifest themselves as follows. Copper promotes graphitization, the appearance of perlite, increases the strength and ductility of the alloy. Vanadium increases the viscosity and ductility of cast iron, improves its structure. Cobalt and nickel increase the hardness and strength of the alloy. Rhenium increases the hardness and performance of cast iron at high temperatures, worsens weldability. Aluminum inhibits the growth of scale. REM deoxidizes cast iron. Beryllium helps to chop grain.
Чугун выплавляют в электропечах и отливают формы. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and molds are cast. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
