机械工业部沈阳真空技术研究所研制的我国第一台VFH-100PT型真空加压气淬炉,已在沈阳市标准件工具厂正式投入生产使用.VFH-100PT型真空加压气淬炉是我国八十年代的最新炉型.该炉是采用单室结构,加压、气冷.最大的装机容量100公斤,淬火最高温度1300℃.工作压力10~(-1)～10~(-4)托,冷炉最低压力1×10~(-5)托.该炉的特点是,冷却速度快,淬透性好,在空炉运行时,由1300℃冷却到65℃,其时间不超过19分钟,特别是适应于大截面尺寸风冷钢淬火.直径100毫米的高速钢棒,可以淬硬到HRC63以上.比负压淬火(650～700托)
The first VFH-100PT vacuum gas quenching furnace developed by Shenyang Institute of Vacuum Technology, Ministry of Machinery Industry, has been put into production in Shenyang Standard Parts Tool Factory .VFH-100PT vacuum pressurized gas quenching furnace is our country The latest furnace of the 80s, the furnace is a single-chamber structure, pressurized, air-cooled. The maximum installed capacity of 100 kg, the maximum temperature quenching 1300 ° C. Working pressure 10 ~ (-1) ~ 10 ~ (-4) Support, the lowest pressure of the cold furnace 1 × 10 ~ (-5) Torr.The furnace is characterized by fast cooling, good hardenability, in the empty furnace operation, cooled from 1300 ℃ to 65 ℃, the time does not exceed 19 Min, especially suitable for large section size air-cooled steel quenching.High-speed steel rod diameter of 100 mm, can be hardened to HRC63 above than the negative pressure quenching (650 ~ 700 torr)
