Embodiment Construction

[0010] Mn13Cr2 wear-resistant alloy material is to add 2% Cr to Mn13 wear-resistant alloy material, and its processing technology is as follows:

[0011] 1. Smelting

[0012] Add 13kg of manganese with a net content of 100kg of scrap iron and steel, and when heated to 1000-1400°C in an intermediate frequency electric furnace to melt into a liquid state, add 2% of chromium with a net content of 4mm particles, 0.2% of scrap copper and 0.7% of silicon;

[0013] 2. Preheating and quenching

[0014] After the above raw materials are melted into a liquid state, pour them into a sand cavity of 15 mesh quartz sand at 1300°C for casting, take them out after 20 minutes, put them into a mixture of 70% water + 30% water glass, and quench at 800-1000°C After 1 hour, the product required for the Mn13Cr2 wear-resistant alloy material is ready for demoulding. Such as grinding balls of mills, liners, tooth plates of crushers, hammer heads, flow parts of slurry pumps, rake teeth of loaders an...

Abstract

The invention discloses a Mn13Cr2 wear-resistant alloy material, belonging to the field of metal materials. Based on Mn13 wear-resistant alloy material, 2% of Cr is added into the Mn13 wear-resistantalloy material; the Mn13Cr2 wear-resistant alloy material prepared by the method is low in price and manufacturing cost, and greatly improves the hardness and the toughness, and the service life of the cast product is prolonged by 4-5 months.

Description

technical field [0001] The invention relates to a Mn13Cr2 wear-resistant alloy material, which belongs to the field of metal materials. Background technique [0002] After more than 40 years of development of domestic wear-resistant materials, the technology and equipment are gradually approaching the international level. At present, there are various types of products, and the materials include: high, medium and low chromium alloy iron, white cast iron, metal composite materials, etc. Casting methods: sand casting, metal mold casting, semi-automatic, automatic casting, etc. Smelting methods: intermediate frequency furnace, power frequency furnace, cupola, electric arc furnace, duplex method smelting, etc. But the variety is single, and the wear life is not ideal. Contents of the invention [0003] The purpose of the present invention is to make up for the shortage of wear-resistant alloy steel materials and provide a high-efficiency, energy-saving and low-consumption p...
