Abstract
Description
Изобретение относится к области металлургии и касается составов сплавов, которые могут быть использованы для изготовления колосников, охлаждающих рам печей, дистанционных гребенок паровых котлов, зубьев и гребков колчеданных печей.The invention relates to the field of metallurgy and relates to alloy compositions that can be used for the manufacture of grates, cooling frames of furnaces, remote combs of steam boilers, teeth and strokes of pyrite furnaces.
Известен жаростойкий сплав, содержащий, маc. %: алюминий 10,0-32,0; углерод 0,001-0,01; хром 0,05-6,0; медь 0,1-3,0; кальций 0,001-0,01; никель 0,05-5,0; бор 0,0003-0,03; кремний ≤ 3,0; железо - остальное [1].A heat-resistant alloy containing, by weight, is known. %: aluminum 10.0-32.0; carbon 0.001-0.01; chromium 0.05-6.0; copper 0.1-3.0; calcium 0.001-0.01; nickel 0.05-5.0; boron 0.0003-0.03; silicon ≤ 3.0; iron - the rest [1].
Задача изобретения состоит в повышении жаростойкости сплава.The objective of the invention is to increase the heat resistance of the alloy.
Технический результат достигается тем, что жаростойкий сплав, содержащий алюминий, углерод, хром, медь, кальций, никель, бор, кремний, железо, дополнительно включает неодим, причем компоненты находятся при следующем соотношении, маc. %: алюминий 28,0-30,0; углерод 0,03-0,05; хром 3,0-5,0; медь 0,03-0,05; кальций 0,0005-0,001; никель 7,0-10,0; бор 0,05-0,1; кремний 0,2-0,3; неодим 0,2-0,3; железо - остальное.The technical result is achieved in that the heat-resistant alloy containing aluminum, carbon, chromium, copper, calcium, nickel, boron, silicon, iron, additionally includes neodymium, and the components are in the following ratio, wt. %: aluminum 28.0-30.0; carbon 0.03-0.05; chrome 3.0-5.0; copper 0.03-0.05; calcium 0.0005-0.001; nickel 7.0-10.0; boron 0.05-0.1; silicon 0.2-0.3; neodymium 0.2-0.3; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе сплава компоненты проявляют себя следующим образом. Хром, неодим, никель, кремний и алюминий препятствуют окислению сплава, обеспечивают повышение жаростойкости. Неодим и кальций раскисляют сплав. Никель улучшает металлическую основу сплава. Медь способствует измельчению зерна. Медь и никель препятствуют образованию и развитию трещин при перепадах температур.In the composition of the alloy, the components manifest themselves as follows. Chrome, neodymium, nickel, silicon and aluminum interfere with the oxidation of the alloy and provide an increase in heat resistance. Neodymium and calcium deoxidize the alloy. Nickel improves the metal base of the alloy. Copper contributes to the grinding of grain. Copper and nickel prevent the formation and development of cracks at temperature extremes.
Жаростойкий сплав выплавляют в электропечах. Отливки подвергают низкотемпературному отжигу при 620-680°С, причем длительность выдержки при отжиге составляет 1 час на 25 мм сечения отливки с последующим охлаждением с печью до 350-370 °С, далее - на воздухе.Heat-resistant alloy is smelted in electric furnaces. The castings are subjected to low-temperature annealing at 620-680 ° C, and the exposure time during annealing is 1 hour per 25 mm of the casting cross-section, followed by cooling with the furnace to 350-370 ° C, then in air.
