近年来,我国开发研制了许多种耐磨钢,在很多场合成功地替代了高锰钢,但对于像风扇磨冲击板这类对强度、韧性和安全系数要求很高的零部件,现有的耐磨钢仍不能满足要求。国产耐磨钢的综合性能不高,其冲击值太低,这与钢的组织的细微差别有关,而热处理工艺不当是造成钢组织细微差别的重要原因这一。本文着重对耐磨钢热处理工艺进行试验研究,目的是研制出一种低合金耐磨钢,用以替代在不能充分发挥加工硬化能力又对韧
In recent years, many kinds of wear resistant steels have been developed in our country, which successfully replace high manganese steels on many occasions. However, for parts with high requirements on strength, toughness and safety factor such as fan impingement boards, Wear-resistant steel still can not meet the requirements. The comprehensive performance of domestic wear-resistant steel is not high, the impact value is too low, which is related to the slight differences in the organization of steel, and improper heat treatment process is an important reason for the nuances of steel tissue. This article focuses on the wear-resistant steel heat treatment process for experimental research, the purpose is to develop a low-alloy wear-resistant steel, to replace the hard work can not give full play to the hardening ability of tough
