Abstract
Description
Изобретение относится к области черной металлургии, в частности, к составам чугуна, который может быть использован в машиностроении, станкостроении.The invention relates to the field of ferrous metallurgy, in particular, to compositions of cast iron, which can be used in mechanical engineering, machine tool industry.
Известен чугун следующего состава, мас. %: углерод 2,8-3,6; кремний 0,9-3,0; марганец 0,3-1,0; медь 0,8-1,2; олово 0,06-0,14; железо - остальное [1].Known cast iron of the following composition, wt. %: carbon 2.8-3.6; silicon 0.9-3.0; manganese 0.3-1.0; copper 0.8-1.2; tin 0.06-0.14; iron - the rest [1].
Задачей изобретения является повышение 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, медь, олово, железо, дополнительно содержит никель, празеодим, эрбий, бор, при следующем соотношении компонентов, мас. %: углерод 4,2-4,4; кремний 1,0-1,6; марганец 0,5-0,9; медь 1,4-1,8; олово 0,06-0,14; никель 1,0-1,4; празеодим 0,15-0,25; эрбий 0,15-0,25; бор 0,13-0,17; железо - остальное.The technical result is achieved by the fact that cast iron, including carbon, silicon, manganese, copper, tin, iron, additionally contains nickel, praseodymium, erbium, boron, in the following ratio of components, wt. %: carbon 4.2-4.4; silicon 1.0-1.6; manganese 0.5-0.9; copper 1.4-1.8; tin 0.06-0.14; nickel 1.0-1.4; praseodymium 0.15-0.25; erbium 0.15-0.25; boron 0.13-0.17; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Никель, бор, эрбий, празеодим, олово повышают твердость чугуна. Празеодим, эрбий раскисляют сплав, способствуют образованию шаровидных выделений графита, имеющих плавные очертания и не ослабляющих металлическую основу чугуна.In the composition of cast iron, the components manifest themselves as follows. Nickel, boron, erbium, praseodymium, tin increase the hardness of cast iron. Praseodymium, erbium deoxidize the alloy, contribute to the formation of spherical emissions of graphite, which have smooth outlines and do not weaken the metal base of cast iron.
Чугун выплавляют в электропечах и отливают в металлические формы, обмазанные огнеупорной глиной. Отливки отжигают при температуре 700-720°С.Cast iron is smelted in electric furnaces and cast into metal molds coated with refractory clay. Castings are annealed at a temperature of 700-720 ° C.
