高锰钢是世界上应用最早的高合金钢之一。至今已有九十多年的历史了。由于该种钢以耐磨著称,故又名耐磨钢。广泛应用在冶金、矿山、化工、建筑等工业部门的破碎机械和易磨损件方面。高锰钢的热处理是决定最大限度发挥其性能的重要工序。在现行的高锰钢热处理工艺中,绝大多数工厂考虑到该种钢的导热性能差,热膨胀系数大,为了减小裂纹倾向,规定在低温时缓慢加热,在650℃保温1～
High manganese steel is one of the earliest high alloy steel in the world. It has been more than 90 years old. As the kind of steel known for wear-resistant, it is also known as wear-resistant steel. Widely used in metallurgy, mining, chemical, construction and other industrial sectors of the broken machinery and easy to wear parts. Heat treatment of high manganese steel is to determine the maximum performance of its important processes. In the current high manganese steel heat treatment process, the vast majority of the plant taking into account the poor thermal conductivity of steel, thermal expansion coefficient, in order to reduce the tendency of cracks, the provisions of slow heating at low temperatures, at 650 ℃ insulation 1 ~
