萝北县减速机械厂试验大型号摆轮专用冷却液淬火新工艺获得成功。该厂从去年4月份起，经多次反复试验，精确选用冷却液的配比，使淬火时间、温度和理化性能完全达到国家标准，提高了减速机的承载能力和使用寿命，批量热加工成本由原来的400元下降到20元，仅此一项每年可为企节 Luobei County deceleration machinery factory test large-scale balance dedicated coolant quenching new technology to be successful. The plant from April last year, after repeated tests, the exact choice of coolant ratio, the quenching time, temperature and physical and chemical properties fully meet the national standard, increased reducer bearing capacity and service life, batch heat processing costs From the original 400 yuan down to 20 yuan, only one of the annual festival can be
