Stretch-resistant metal casting

Abstract

The invention provides a stretch-resistant metal casting, and particularly relates to the field of metal castings. The casting is prepared from 90-110 parts of iron, 0.5-1.5 parts of polonium, 1-3 parts of iridium, 1-2 parts of osmium, 1-2 parts of palladium, 1-10 parts of molybdenum, 1-5 parts of manganese, 1-5 parts of zirconium, 1-2 parts of yttrium, 1-3 parts of silicon, 1-5 parts of copper, 1-4 parts of scandium, 1-2 parts of chromium, 1-2 parts of tellurium, 1-3 parts of nickel and other unavoidable trace impurities. The stretch-resistant property is good, the service life of the castingis prolonged, the production efficiency is improved, and the production safety is ensured.

Description

technical field [0001] The invention belongs to a stretch-resistant metal casting, and in particular relates to the field of metal castings. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , the obtained objects have a certain shape, size and performance; there are many classification methods for castings: according to the different metal materials used, they are divided into steel castings, iron castings, copper castings, aluminum castings, magnesium castings, Zinc castings, titanium castings, etc. Each type of casting can be further divided into different types according to its chemical composition or metallographic structure. For example, iron castings can be divided into gray iron castings, ductile iron castings, vermi...

AI Technical Summary

Problems solved by technology

For example, iron castings can be divided into gray iron castings, ductile iron castings, vermicular graphite iron castings, malleable iron castings, alloy iron castings, etc.; according to different casting methods, castings can be divided into ordinary sand castings, metal castings, die castings , centrifugal castings, continuous castings, investment castings, ceramic castings, electroslag remelting castings, bimetallic castings, etc.; the tensile properties of metal castings are very important, which is related to the safety and efficiency of production, but the existing metal The tensile strength of castings still needs to be further improved;
