Abstract
Description
Изобретение относится к области черной металлургии, в частности, к составам сталей, используемых для изготовления деталей печей, тепловых агрегатов, труб.The invention relates to the field of ferrous metallurgy, in particular, to the compositions of steels used for the manufacture of parts of furnaces, thermal units, pipes.
Известна сталь, содержащая мас. %: углерод 0,08-0,2; кремний 0,1-1,0; марганец 0,6-0,8; хром 18,0-24,0; медь 0,8-3,5; ванадий 0,05-0,1;ниобий 0,1-0,35; кальций 0,01-0,07; железо - остальное [1].Known steel containing wt. %: carbon 0.08-0.2; silicon 0.1-1.0; manganese 0.6-0.8; chrome 18.0-24.0; copper 0.8-3.5; vanadium 0.05-0.1; niobium 0.1-0.35; calcium 0.01-0.07; iron - the rest [1].
Задача изобретения - повышение термостойкости стали.The objective of the invention is to increase the heat resistance of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, хром, медь, ванадий, ниобий, кальций, железо, дополнительно содержит бор, алюминий, кобальт, гафний при следующем соотношении компонентов, мас. %: углерод 0,1-0,2; кремний 0,5-1,0; марганец 0,8-1,2; хром 20,0-24,0; медь 0,4-0,6; ванадий 0,15-0,25; ниобий 0,2-0,4; кальций 0,005-0,01; бор 0,03-0,05; алюминий 0,15-0,25; кобальт 0,2-0,4; гафний 0,3-0,4; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, copper, vanadium, niobium, calcium, iron, additionally contains boron, aluminum, cobalt, hafnium in the following ratio of components, wt. %: carbon 0.1-0.2; silicon 0.5-1.0; manganese 0.8-1.2; chrome 20.0-24.0; copper 0.4-0.6; vanadium 0.15-0.25; niobium 0.2-0.4; calcium 0.005-0.01; boron 0.03-0.05; aluminum 0.15-0.25; cobalt 0.2-0.4; hafnium 0.3-0.4; iron is the rest.
В таблице приведены составы стали.
Хром, ниобий, ванадий, гафний, кобальт, медь обеспечивают повышение термостойкости стали. Бор способствует равномерному прогреву и охлаждению стальных изделий. Ванадий, ниобий, гафний, алюминий препятствуют возникновению и развитию трещин при перепадах температур. Хром тормозит рост окалины. Кальций раскисляет сталь. Кобальт способствует улучшению структуры сплава.Chrome, niobium, vanadium, hafnium, cobalt, copper provide an increase in the heat resistance of steel. Boron promotes uniform heating and cooling of steel products. Vanadium, niobium, hafnium, aluminum prevent the occurrence and development of cracks at temperature extremes. Chrome inhibits the growth of scale. Calcium deoxidizes steel. Cobalt improves the structure of the alloy.
Сталь может быть выплавлена в электропечах. Отливки подвергают нагреву до температуры 1100-1150°С и закалке в воде.Steel can be smelted in electric furnaces. The castings are heated to a temperature of 1100-1150 ° C and quenched in water.
