Preparation method of wear-resistant alloy cast iron

Abstract

The invention discloses a preparation method of an abrasion-resistant alloy cast iron. The preparation method is composed of the following components in percentage by weight: 2.7-3.5% of carbon, 0.5-1.2% of silicon, 0.5-1.5% of copper, 0.6-1.5% of manganese, 20-28% of chromium, 0.5-1% of molybdenum, 1-2.8% of nickel, 0.05-0.3% of boron and the balance of iron. The cast iron has excellent abrasion resistance, and also has impact resistance; the preparation method is simple in process and low in number of devices adopted, and thus convenient to popularize.

Description

technical field [0001] The patent of the invention relates to a wear-resistant alloy cast iron, in particular to a preparation method of a novel wear-resistant alloy cast iron material. Background technique [0002] Wear-resistant alloys are mainly used in mining machinery and equipment, and are key components in the manufacture of ore grinding and pulverization. At present, hammer heads and other accessories on domestic ore processing machinery and equipment are made of high manganese steel. The hammer head made of high manganese steel Good impact toughness but poor wear resistance, short service life, fast wear, short replacement cycle, increased labor intensity of workers, and easy sand fall, sand leakage, affecting the surrounding environment, seriously affecting the continuous operation of mechanical equipment And output benefit, the existing wear-resistant materials in the use process of mining machinery have the disadvantages of non-wear resistance, high use cost, lar...
