Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам сталей, используемых для изготовления инструмента горячего деформирования, деталей тепловых агрегатов.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels used for the manufacture of hot deformation tools, parts of thermal units.
Известна сталь, содержащая мас.%: углерод 0,2-0,3; марганец 0,25-0,6; кремний 0,6-1,2; хром 4,5-5,5; кальций 0,001-0,01; титан 0,01-0,1; иттрий 0,001-0,01; железо - остальное [1].Known steel containing wt.%: Carbon 0.2-0.3; manganese 0.25-0.6; silicon 0.6-1.2; chrome 4.5-5.5; calcium 0.001-0.01; titanium 0.01-0.1; yttrium 0.001-0.01; 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, марганец, кремний, хром, кальций, титан, иттрий, железо, дополнительно содержит серебро и вольфрам при следующем соотношении компонентов, мас. %: углерод 0,2-0,3; марганец 3,5-3,8; кремний 0,8-1,2; хром 4,5-5,5; кальций 0,001-0,002; титан 0,01-0,02; иттрий 2,6-3,0; серебро 2,2-2,6; вольфрам 3,0-3,6; железо - остальное.The technical result is achieved in that the steel containing carbon, manganese, silicon, chromium, calcium, titanium, yttrium, iron, additionally contains silver and tungsten in the following ratio of components, wt. %: carbon 0.2-0.3; manganese 3.5-3.8; silicon 0.8-1.2; chrome 4.5-5.5; calcium 0.001-0.002; titanium 0.01-0.02; yttrium 2.6-3.0; silver 2.2-2.6; tungsten 3.0-3.6; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
Термостойкость (количество циклов нагрев → охлаждение, при изменении температур от 20 до 850°С) составит ~150 теплосмен.Heat resistance (the number of heating → cooling cycles, when the temperature changes from 20 to 850 ° C) will be ~ 150 heat changes.
Повышение термостойкости стали достигается за счет комплексного влияния компонентов, входящих в ее состав. Хром обеспечивает повышение жаростойкости и термостойкости стали. Серебро способствует равномерному прогреву и охлаждению стальных изделий. Вольфрам повышает прочность стали, препятствует возникновению и развитию трещин при перепадах температур. Кальций и иттрий раскисляют сталь, титан способствует улучшению структуры сплава.Improving the heat resistance of steel is achieved due to the complex effect of the components that make up its composition. Chromium provides increased heat resistance and heat resistance of steel. Silver contributes to uniform heating and cooling of steel products. Tungsten increases the strength of steel, prevents the occurrence and development of cracks at temperature extremes. Calcium and yttrium deoxidize steel, titanium helps to improve 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.
