1953年冬,苏联热处理专家捷哥洽廖夫,曾到我厂介绍快速加热法,使我厂的高锰铜铸件水韧处理的产量提高了一倍(该铸件是在反射炉加热的)。当时我们对这一先进经验的优点体会的不够,以为“快速加热在反射炉行,在盐炉不一定行”;“本来生产上问题不大,如果用快速加热出了毛病可坏了”。1955年第二季度,热处理变形和淬裂成了我们生产中的关键问题。6月下旬专家又到 The winter of 1953, the Soviet heat treatment expert Jie Geqia Liao Fu, I was introduced to the plant rapid heating method, so that my factory high manganese castings Duffering treatment yield doubled (the castings are heated in a reverberatory furnace). At that time, we did not realize the merits of this advanced experience. We thought that “rapid heating at the refiner’s furnace is not necessarily at the salt furnace.” “It was not a problem in production, and if it was heated rapidly, something went wrong.” In the second quarter of 1955, heat treatment deformation and quench cracking became the key issues in our production. Experts arrived in late June
