Description

Изобретение относится к области черной металлургии, в частности к составам сплавов на основе железа, которые могут быть использованы в средненагруженных муфтах сцепления, тормозах и других устройствах.The invention relates to the field of ferrous metallurgy, in particular to compositions of alloys based on iron, which can be used in medium-loaded clutches, brakes and other devices.

Известен сплав на основе железа следующего состава, мас.%: углерод 3,0-3,3; кремний 1,3-1,7; марганец 0,8-1,2; хром ≤0,3; никель ≤0,5; сера ≤0,15; фосфор ≤0,3; железо - остальное [1].A known alloy based on iron of the following composition, wt.%: Carbon 3.0-3.3; silicon 1.3-1.7; manganese 0.8-1.2; chrome ≤0.3; nickel ≤0.5; sulfur ≤0.15; phosphorus ≤0.3; iron - the rest [1].

Задача изобретения состоит в повышении твердости сплава.The objective of the invention is to increase the hardness of the alloy.

Технический результат достигается тем, что сплав на основе железа, включающий углерод, кремний, марганец, хром, никель, фосфор, железо, дополнительно содержит гафний и бор при следующем соотношении компонентов, мас.%: углерод 5,0-5,5; кремний 1,3-1,7; марганец 0,8-1,2; хром 0,1-0,2; никель 0,6-1,0; фосфор 0,1-0,3; гафний 4,4-5,0; бор 0,7-1,1; железо - остальное.The technical result is achieved in that the alloy based on iron, including carbon, silicon, manganese, chromium, nickel, phosphorus, iron, additionally contains hafnium and boron in the following ratio of components, wt.%: Carbon 5,0-5,5; silicon 1.3-1.7; manganese 0.8-1.2; chrome 0.1-0.2; nickel 0.6-1.0; phosphorus 0.1-0.3; hafnium 4.4-5.0; boron 0.7-1.1; iron is the rest.

В таблице приведены составы сплава на основе железа.The table shows the compositions of the alloy based on iron.

Марганец, хром, фосфор, бор, гафний повышают твердость сплава. Никель улучшает металлическую основу сплава.Manganese, chromium, phosphorus, boron, hafnium increase the hardness of the alloy. Nickel improves the metal base of the alloy.

Сплав 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.The alloy 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.
