Abstract
Изобретение относитс к металлургии и может быть использовано при производстве тонкостенных чугунных труб центробежным способом или непрерьшной выт жкой. Цель изобретени повышение предела выносливости при изгибе и снижение брака отливок достигаетс тем, что чугун, содержащий углерод, кремний, марганец, цирконий, алюминий, редкоземельньй элемент и железо дополнительно содержит силикаты кальци и барий, а в качестве редкоземельного элемента церий при следующем соотношении компонентов, мас.%: С 2,9-3.6; Si 1,6-2,3; Мп 0,3-0,8; Zr 0,12-0,25; А1 0,05-0,20; Се 0,02-0,07; Ва 0,03- с 0,08; силикаты кальци 0,03-0,12; железо остальное. 2 табл.The invention relates to metallurgy and can be used in the manufacture of thin-walled cast-iron pipes by the centrifugal method or by continuous drawing. The aim of the invention is to increase the bending endurance limit and reduce cast rejects by the fact that cast iron containing carbon, silicon, manganese, zirconium, aluminum, a rare earth element and iron additionally contains calcium and barium silicates, and as a rare earth element cerium in the following ratio of components wt.%: C 2.9-3.6; Si 1.6-2.3; Mp 0.3-0.8; Zr 0.12-0.25; A1 0.05-0.20; Ce 0.02-0.07; Ba 0.03 - with 0.08; calcium silicates 0.03-0.12; iron else. 2 tab.
Description
Изобретение относитс к металлур гии, в частности к составам чугуна дл производства труб.The invention relates to metallurgy, in particular to cast iron compositions for the production of pipes.
Целью изобретени вл етс повышение предела выносливости при изгибе и снижение брака отливок.The aim of the invention is to increase the bending endurance limit and reduce cast rejects.
Свойства чугуна предлагаемого и известного составов приведены в табл.1 и 2.The properties of cast iron of the proposed and known compositions are given in table 1 and 2.
Как.сЛедуёт из табл.1 и 2, дополнительньй ввод в состав чугуна силикатов кальци и бари обеспечивает уменьшение брака отливок по газовым раковинам, 1плаковым засорам и т.п. Силикаты кальци обеспечивают раскисление и модифицирование жидкого чугуна, повышают его плотность Барий,позвол ет повысить содержание перлита в чугуне, стабилизирует его структуру по сечению отливки.Alone from Tables 1 and 2, the addition of calcium silicates and barium to the composition of cast iron ensures a reduction in the waste of castings in gas shells, 1 slag clogging, etc. Calcium silicates provide deoxidation and modification of liquid iron, increase its density, barium, increase the content of perlite in cast iron, stabilize its structure over the section of the casting.
Силикаты кальци присаживают в копильник вагранки. Силикобарий ввод т в ковш при выпуске чугуна из вагранки.Calcium silicates are seated in a cupola furnace. Silicobarium is introduced into the ladle when the iron is released from the cupola.
