Abstract
Description
Изобретение относится к металлургии, в частности к производству чугунов, используемых в машиностроении, станкостроении и других отраслях промышленности. The invention relates to metallurgy, in particular to the production of cast irons used in mechanical engineering, machine tool industry and other industries.
Известны чугуны, содержащие углерод, кремний, марганец и другие компоненты (1). Cast iron containing carbon, silicon, manganese and other components are known (1).
Известен также чугун, содержащий следующие компоненты, мас. % : углерод 2,9-3,3; кремний 1,6-1,9; марганец 0,6-0,9; олово 0,08-0,12; титан 0,12-0,15; железо - остальное (2). Also known is cast iron containing the following components, wt. %: carbon 2.9-3.3; silicon 1.6-1.9; manganese 0.6-0.9; tin 0.08-0.12; titanium 0.12-0.15; iron - the rest (2).
Целью изобретения является повышение литейных свойств чугуна. The aim of the invention is to improve the casting properties of cast iron.
Цель достигается тем, что в состав чугуна дополнительно вводят фосфор и азот, при следующем соотношении компонентов, мас. % : углерод 2,9-3,3; кремний 1,6-1,9; марганец 0,6-0,9; титан 0,3-0,4; фосфор 0,05-0,1; азот 0,07-0,1; железо остальное. The goal is achieved by the fact that phosphorus and nitrogen are additionally introduced into the composition of cast iron, in the following ratio of components, wt. %: carbon 2.9-3.3; silicon 1.6-1.9; manganese 0.6-0.9; titanium 0.3-0.4; phosphorus 0.05-0.1; nitrogen 0.07-0.1; iron the rest.
В таблице приведены составы предложенного чугуна. The table shows the compositions of the proposed cast iron.
Введение в состав чугуна азота способствует повышению жидкотекучести металла. Увеличение содержания титана предотвращает выделение азота в виде пузырьков при затвердевании чугуна, благодаря чему литье получается практически однородным и не содержащим пустот. Присутствие фосфора в указанном количестве повышает жидкотекучесть чугуна, так как фосфор образует легкоплавкую эвтектику (950оС), состоящую из аустенита и фосфида железа.The introduction of nitrogen in the composition of cast iron increases the fluidity of the metal. The increase in titanium content prevents the release of nitrogen in the form of bubbles during the solidification of cast iron, so that the casting is almost uniform and does not contain voids. The presence of phosphorus in a specified amount improves castability of cast iron, so as phosphorus forms a low melting eutectic (950 ° C), consisting of austenite and iron phosphide.
Жидкотекучесть предложенного чугуна составляет 940-950 мм. Объем усадочной раковины 0,05-0,1% для всех составов. The fluidity of the proposed cast iron is 940-950 mm. The volume of the shrink shell is 0.05-0.1% for all compositions.
Кроме повышенных литейных свойств чугун обладает высокой прочностью, твердостью, износостойкостью. In addition to increased casting properties, cast iron has high strength, hardness, and wear resistance.
