Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам сталей, используемых для изготовления деталей печей, двигателей, тепловых агрегатов.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels used for the manufacture of parts of furnaces, engines, thermal units.
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 жаростойкости 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 вольфрам, гафний, кобальт 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 0,15-0,2; ванадий 0,15-0,2; ниобий 0,15-0,2; кальций 0,005-0,01; вольфрам 0,4-0,6; гафний 0,15-0,2; кобальт 0,45-0,65; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, copper, vanadium, niobium, calcium, iron, additionally contains tungsten, hafnium, cobalt 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 0.15-0.2; vanadium 0.15-0.2; niobium 0.15-0.2; calcium 0.005-0.01; tungsten 0.4-0.6; hafnium 0.15-0.2; cobalt 0.45-0.65; iron is the rest.
В таблице приведены составы жаростойкой стали.The table shows the compositions of heat-resistant steel.
Хром, кобальт, вольфрам, гафний обеспечивают повышение жаростойкости стали. Медь способствует равномерному прогреву и охлаждению стали. Ванадий, ниобий, вольфрам, гафний препятствуют возникновению и развитию трещин при перепадах температур. Кальций раскисляет сталь.Chrome, cobalt, tungsten, hafnium provide increased heat resistance of steel. Copper contributes to uniform heating and cooling of steel. Vanadium, niobium, tungsten, hafnium prevent the occurrence and development of cracks at temperature extremes. Calcium deoxidizes steel.
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.
