一、序言我厂75年接受新产品钙硫易切钢的试验任务,由于工艺手段没有解决,任务一直没有完成。78年我们着重研究和制作了喷射冶金的心脏——喷粉罐,并进行一系列空载试验工作。79年在150公斤感应炉上进行参数试验中喷吹钙硫易切钢获得成功。同时喷吹了炮钢、舰艇钢、轴承钢和渗碳轴承钢等。效果显著,钢中含氧量一般都比原来下降2倍,有的
First, the preface Our factory in 75 years to accept the new test of calcium and sulfur free cutting steel test tasks, due to technical means not resolved, the task has not been completed. During the 78 years, we focused on researching and manufacturing the heart of jet metallurgy - dusking jars and conducting a series of no-load tests. 79 years in the 150 kg induction furnace parameters of the test injection of calcium and sulfur free cutting steel was successful. At the same time blowing the gun steel, ship steel, bearing steel and carburizing bearing steel. The effect is obvious, the oxygen content of steel is generally 2 times lower than the original, and some
