我厂采用瓦房店市石油化工厂生产的超速淬火油,其技术指标参见第62页广告。从一段时间试用情况看,证明该油冷却性能良好,可以代替水—油双液淬火,对碳素工具钢、低合金工具钢、碳素结构钢及Gcr15钢制中、小型零件的淬火,均能达到技术要求,尤其适合于形状复杂、淬火易变形开裂的零件。现将使用情况简介如下: (1)我厂对T8A、45钢制形状复杂、易变形、开裂的中、小型零件,以往通常采用水—油双液淬火,工件在水中停留的时间不易控制,加上操作者的熟练程度各异,从而常出现淬火废品。采用超速淬火油淬火后,对小型零件不需提高淬火加热温度,在
I plant using Wafangdian Petrochemical Factory production of ultra-quenching oil, the technical indicators see page 62 ads. From a trial period of time to see that the oil cooling performance is good, you can instead of water - oil dual-liquid quenching, carbon tool steel, low alloy tool steel, carbon steel and Gcr15 steel small and medium parts of the quenching, are Can meet the technical requirements, especially for complex shape, easy to deform cracking cracking parts. Now the use of briefings are as follows: (1) I plant on T8A, 45 steel complex shape, deformation, cracking of small and medium parts, the past usually used water - oil dual liquid quenching, the workpiece in the water is not easy to control the time spent, Coupled with the operators of different proficiency, which often appear quenched waste. After quenching oil quenching, the need for small parts without quenching heating temperature, at
