Problems solved by technology

Due to any liner material, under the working conditions of pulverization, there is relatively serious wear and tear. When serious pits and grooves appear in the wear, the pulverization efficiency of the coal mill decreases, and the output of the coal mill is insufficient. Some Some manufacturers are using high-chromium cast iron linings, but high-chromium cast iron linings have high cost and are easy to break. This invention proposes a new solution to the above problems

Abstract

The invention relates to a preparation process of an alloy lining plate. The alloy lining plate comprises the following chemical elements including, by weight, 6.3%-6.7% of chromium, 1.3%-1.5% of carbon, 6.75%-8.32% of manganese, 0.25%-0.39% of silicon, 0.15%-0.5% of zirconium, 0.05%-0.17% of magnesium, 0.36%-0.55% of copper, 0.09%-0.18% of titanium, 0.04%-0.06% of rhenium, less than or equal to 0.06% of sulfonium, less than or equal to 0.06% of phosphorus and the balance Fe. The alloy lining plate prepared by the preparation process has good comprehensive performance, high hardness, wear resistance, high temperature resistance, good toughness and good impact resistance, and effectively solves some problems of lining plates in the prior art.

Description

technical field [0001] The invention relates to the technical field of lining plate preparation, in particular to a preparation process of an alloy lining plate. Background technique [0002] With the in-depth development of the national economy, new technologies, new equipment, and new materials have attracted more and more attention. According to the statistics of my country's metallurgy, building materials, electric power, agricultural machinery, coal and other five systems plus the incomplete statistics of machinery departments such as automobiles, tractors, and construction machinery, my country's annual consumption of metal wear-resistant materials is about 3 million tons or more. Wear-resistant parts, its wear resistance directly affects the operation rate of milling, pulverized coal quality, material consumption and production cost. Due to any liner material, under the working conditions of pulverization, there is relatively serious wear and tear. When serious pits a...
