Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован, например, для изготовления подшипников скольжения.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used, for example, for the manufacture of plain bearings.
Известен чугун следующего состава, мас.%: углерод 3,5-4,0; кремний 2,5-3,5; марганец 8,0-12,0; олово 0,5-1,0; медь 0,2-0,7; железо остальное.Known cast iron of the following composition, wt.%: Carbon 3,5-4,0; silicon 2.5-3.5; manganese 8.0-12.0; tin 0.5-1.0; copper 0.2-0.7; iron the rest.
Задача изобретения состоит в повышении твердости чугуна.The objective of the invention is to increase the hardness of cast iron.
Технический результат достигается тем, что чугун, включающий углерод, кремний, марганец, олово, медь, железо, дополнительно содержит самарий, молибден, бор при следующем соотношении компонентов, мас.%: углерод 3,5-4,0; кремний 2,5-3,5; марганец 16,0-18,0; олово 0,5-1,0; медь 0,2-0,7; самарий 0,05-0,1; молибден 0,5-0,7; бор 1,6-2,0; железо остальное.The technical result is achieved by the fact that cast iron, including carbon, silicon, manganese, tin, copper, iron, additionally contains samarium, molybdenum, boron in the following ratio of components, wt.%: Carbon 3,5-4,0; silicon 2.5-3.5; manganese 16.0-18.0; tin 0.5-1.0; copper 0.2-0.7; samarium 0.05-0.1; molybdenum 0.5-0.7; boron 1.6-2.0; iron the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Твердость чугуна в литом состоянии составит -280 НВ для всех приведенных в таблице составов.The hardness of cast iron will be -280 HB for all the compositions listed in the table.
В составе чугуна компоненты проявляют себя следующим образом. Бор и олово увеличивают твердость чугуна. Самарий раскисляет сплав. Молибден, марганец и медь повышают прочность и износостойкость сплава, препятствуют возникновению трещин в изделиях.In the composition of cast iron, the components manifest themselves as follows. Boron and tin increase the hardness of cast iron. Samaria deoxidizes the alloy. Molybdenum, manganese and copper increase the strength and wear resistance of the alloy, prevent the occurrence of cracks in the products.
Чугун выплавляют в электропечах и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Для снятия внутренних напряжений отливки отжигают при температуре 550°С.Cast iron is smelted in electric furnaces and cast into hot (400-450 ° C) metal molds coated with refractory clay. To relieve internal stresses, castings are annealed at a temperature of 550 ° C.
