前言轴承零件(套圈、滚动体)为 GCr15钢制件,含碳量在1%左右,含铬量为1.5%。在空气中加热发生氧化和脱碳。我厂自1964年以来采用了木炭保护气氛,虽有一定效果,但未根除零件的氧化和脱碳。为了改变这种落后面貌,厂、校结合设计制造出一台吸热式可控气氛发生器,于1976年7月份进行了热调试和试生产。试生产结果表明,用丙烷为原料的吸热式可控气氛通往大型的开口震底炉中作为保护
Preface Bearing components (ferrules, rolling elements) are GCr15 steel parts with a carbon content of about 1% and a chromium content of 1.5%. In the air heating occurs oxidation and decarbonization. I plant since 1964 using charcoal to protect the atmosphere, although a certain effect, but did not eradicate the oxidation and decarbonization parts. In order to change this backwardness, the factory and school jointly designed and manufactured a heat-absorbing and controlled atmosphere generator. In July 1976, it conducted thermal commissioning and trial production. Trial production results show that propane as the starting material of the endothermic controllable atmosphere leading to a large open heart-shaking furnace as a protection
