Description
Изобретение относится к области металлургии, в частности к составам легирующих сплавов серого чугуна.The invention relates to the field of metallurgy, in particular to compositions of alloying alloys of gray cast iron.
Известен сплав для легирования чугуна, содержащий, мас.%: хром 25,0-50,0; кремний 20,0-30,0; алюминий 5,0-10,0; марганец 1,0-2,0; углерод 0,5-3,0; теллур 1,0-5,0; железо - остальное [1].Known alloy for alloying cast iron, containing, wt.%: Chromium 25.0-50.0; silicon 20.0-30.0; aluminum 5.0-10.0; manganese 1.0-2.0; carbon 0.5-3.0; tellurium 1.0-5.0; iron - the rest [1].
Задачей изобретения является повышение прочности чугуна.The objective of the invention is to increase the strength of cast iron.
Технический результат достигается тем, что сплав для легирования серого чугуна, содержащий хром, кремний, алюминий, марганец, железо, дополнительно включает ниобий, цирконий и бор при следующем соотношении компонентов, мас.%: хром 20,0-30,0; кремний 5,0-10,0; алюминий 5,0-10,0; марганец 1,0-2,0; ниобий 10,0-20,0; цирконий 10,0-20,0; бор 1,0-2,0; железо - остальное.The technical result is achieved in that the alloy for alloying gray cast iron containing chromium, silicon, aluminum, manganese, iron, additionally includes niobium, zirconium and boron in the following ratio of components, wt.%: Chromium 20.0-30.0; silicon 5.0-10.0; aluminum 5.0-10.0; manganese 1.0-2.0; niobium 10.0-20.0; zirconium 10.0-20.0; boron 1.0-2.0; iron is the rest.
В табл.1 приведены составы сплава для легирования чугуна, в табл.2 - характеристика прочности чугуна (при расходе сплава 1,5%).Table 1 shows the alloy compositions for alloying cast iron, and in Table 2, the strength characteristics of cast iron (at an alloy consumption of 1.5%).
Введенные в серый чугун компоненты, входящие в состав лигатуры, проявляют себя следующим образом. Кремний способствует выделению графита. Хром, марганец и бор стабилизируют карбиды. Алюминий раскисляет чугун. Ниобий упрочняет твердый раствор, препятствует образованию трещин. Цирконий способствует получению мелкозернистой структуры серого чугуна.The components included in the gray cast iron, which are part of the ligature, manifest themselves as follows. Silicon promotes the release of graphite. Chromium, manganese and boron stabilize carbides. Aluminum deoxidizes cast iron. Niobium strengthens the solid solution, prevents the formation of cracks. Zirconium helps to produce a fine-grained structure of gray cast iron.
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.
