Description
Изобретение относится к области металлургии, в частности к составам сплавов для легирования антифрикционных чугунов.The invention relates to the field of metallurgy, in particular to alloy compositions for alloying antifriction cast irons.
Известен сплав для легирования антифрикционных чугунов, содержащий, мас.%: РЗМ 15,0-20,0; углерод 0,5-0,8; кремний 5,0-10,0; алюминий 0,5-4,0; хром 15,0-20,0; никель 35,0-45,0; магний 0,5-1,0; железо - остальное [1].Known alloy for alloying antifriction cast irons, containing, wt.%: REM 15.0-20.0; carbon 0.5-0.8; silicon 5.0-10.0; aluminum 0.5-4.0; chrome 15.0-20.0; nickel 35.0-45.0; magnesium 0.5-1.0; iron - the rest [1].
Задача изобретения состоит в повышении износостойкости чугуна, обработанного сплавом.The objective of the invention is to increase the wear resistance of alloy cast iron.
Технический результат достигается тем, что сплав для легирования антифрикционных чугунов, содержащий РЗМ, углерод, кремний, алюминий, хром, никель, магний, железо, дополнительно включает цирконий и медь при следующем соотношении компонентов, мас.%: РЗМ 12,0-18,0; углерод 0,5-1,5; кремний 5,0-10,0; алюминий 0,5-1,5; хром 12,0-18,0; никель 30,0-35,0; магний 0,5-1,0; цирконий 12,0-18,0; медь 5,0-10,0; железо - остальное.The technical result is achieved in that the alloy for alloying anti-friction cast irons containing REM, carbon, silicon, aluminum, chromium, nickel, magnesium, iron, additionally includes zirconium and copper in the following ratio of components, wt.%: REM 12.0-18, 0; carbon 0.5-1.5; silicon 5.0-10.0; aluminum 0.5-1.5; chrome 12.0-18.0; nickel 30.0-35.0; magnesium 0.5-1.0; zirconium 12.0-18.0; copper 5.0-10.0; iron is the rest.
В табл.1 приведены составы сплава для легирования, в табл.2 - износ чугуна, обработанного сплавом (при расходе сплава 2%).Table 1 shows the alloy compositions for alloying, and in Table 2 shows the wear of cast iron treated with the alloy (at an alloy consumption of 2%).
Введенные в серый чугун компоненты, входящие в состав лигатуры, проявляют себя следующим образом. Кремний способствует выделению графита. Хром и никель повышают прочность и твердость чугуна. Медь способствует увеличению пластичности сплава. Алюминий, магний и РЗМ раскисляют чугун, способствуют получению мелкозернистой структуры. Цирконий упрочняет границы зерен.The components included in the gray cast iron, which are part of the ligature, manifest themselves as follows. Silicon promotes the release of graphite. Chrome and nickel increase the strength and hardness of cast iron. Copper helps to increase the ductility of the alloy. Aluminum, magnesium and rare-earth metals deoxidize cast iron, contribute to obtaining a fine-grained structure. Zirconium strengthens grain boundaries.
Сплав для легирования вводят в ковш в нагретом до температуры 200-250°С состоянии. Температура чугуна при введении сплава 1360-1380°С. Оптимальное время выдержки чугуна в ковше 5-8 мин.The alloy for alloying is introduced into the bucket in a state heated to a temperature of 200-250 ° C. The temperature of cast iron with the introduction of the alloy 1360-1380 ° C. The optimum exposure time of cast iron in the ladle is 5-8 minutes.
