Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован в энергетическом машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used in power engineering.
Известен чугун следующего состава, мас. %: углерод 1,7-3,8; кремний 0,01-2,5; марганец 0,01-1,0; молибден 0,01-2,0; медь 0-0,2; тантал 0,001-0,1; бериллий 0,01 -0,2; железо - остальное [1].Known cast iron of the following composition, wt. %: carbon 1.7-3.8; silicon 0.01-2.5; manganese 0.01-1.0; molybdenum 0.01-2.0; copper 0-0.2; tantalum 0.001-0.1; beryllium 0.01 -0.2; iron - the rest [1].
Задача изобретения состоит в повышении термостойкости чугуна.The objective of the invention is to increase the heat resistance of cast iron.
Технический результат достигается тем, что в чугуне, содержащем углерод, кремний, марганец, молибден, медь, тантал, бериллий, железо, компоненты находятся при следующем соотношении, мас. %: углерод 3,0-3,6; кремний 3,0-3,6; марганец 1,4-1,6; молибден 1,6-2,0; медь 2,3-2,9; тантал 0,12-0,18; бериллий 0,003-0,005; железо - остальное.The technical result is achieved by the fact that in cast iron containing carbon, silicon, manganese, molybdenum, copper, tantalum, beryllium, iron, the components are in the following ratio, wt. %: carbon 3.0-3.6; silicon 3.0-3.6; manganese 1.4-1.6; molybdenum 1.6-2.0; copper 2.3-2.9; tantalum 0.12-0.18; beryllium 0.003-0.005; iron is the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
В составе чугуна компоненты проявляют себя следующим образом. Молибден, медь и тантал упрочняют сплав. Молибден препятствует возникновению трещин при перепадах температур. Медь способствует равномерному прогреву и охлаждению отливок. Бериллий придает мелкозернистость структуре чугуна.In the composition of cast iron, the components manifest themselves as follows. Molybdenum, copper and tantalum strengthen the alloy. Molybdenum prevents cracking during temperature changes. Copper promotes uniform heating and cooling of castings. Beryllium gives a fine grain structure to cast iron.
Чугун выплавляют в электропечах и отливают в формы. Отливки подвергают отжигу при температуре 720-740°С с последующим охлаждением на воздухе.Cast iron is smelted in electric furnaces and cast into molds. The castings are annealed at a temperature of 720-740 ° C, followed by cooling in air.
