Abstract
Description
Изобретение относится к области металлургии, в частности к производству чугунов, используемых для изготовления отливок, работающих в условиях повышенных температур, например, деталей тепловых агрегатов, а также металлургического оборудования. The invention relates to the field of metallurgy, in particular to the production of cast irons used for the manufacture of castings operating at elevated temperatures, for example, parts of thermal units, as well as metallurgical equipment.
Известен чугун, содержащий углерод, кремний, марганец и другие компоненты (1). Known cast iron containing carbon, silicon, manganese and other components (1).
Известен также чугун, содержащий следующие компоненты, мас. % : углерод 1,5-2,4; кремний 5,0-7,0; марганец 0,1-0,6; хром 0,1-0,3; железо - остальное (2). Жаростойкость такого чугуна, определяемая уменьшением веса при 1000оС составляет 13,6-17,4 г/м2 ч.Also known is cast iron containing the following components, wt. %: carbon 1.5-2.4; silicon 5.0-7.0; manganese 0.1-0.6; chrome 0.1-0.3; iron - the rest (2). The heat resistance of such cast iron, determined by the decrease in weight at 1000 about C is 13.6-17.4 g / m 2 hours
Целью изобретения является повышение жаростойкости чугуна. The aim of the invention is to increase the heat resistance of cast iron.
Цель достигается тем, что в состав чугуна дополнительно вводят вольфрам и тантал, при следующем соотношении компонентов, мас. % : углерод 2,0-2,4; кремний 6,0-7,0; марганец 0,1-0,6; хром 2,0-3,0; вольфрам 1,0-2,0; тантал 0,3-0,5; железо остальное. The goal is achieved by the fact that tungsten and tantalum are additionally introduced into the composition of cast iron, in the following ratio of components, wt. %: carbon 2.0-2.4; silicon 6.0-7.0; manganese 0.1-0.6; chrome 2.0-3.0; tungsten 1.0-2.0; tantalum 0.3-0.5; iron the rest.
В таблице приведены составы предложенного чугуна. The table shows the compositions of the proposed cast iron.
Жаростойкость такого чугуна, определяемая уменьшением веса при 1000оС, составляет 6-9 г/м2 ч для всех составов.The heat resistance of such cast iron, determined by the reduction in weight at 1000 about C, is 6-9 g / m 2 h for all compositions.
