北京航空工艺研究所经过两年的努力,前不久完成了WZL-3型真空钎焊、气淬电炉的研制任务,经所科技委鉴定后,已交付原航天部23所使用。 WZL-3的研制成功,表明我国钎焊及热处理用高真空电炉的设计与制造技术又迈进了一步。它具有以下特点: 1.加热器分三组,分区调节和控制温度,均温区大,均温区温差小; 2.充气、强制循环冷却的气淬系统设计合理,不影响
Beijing Institute of Aeronautics Technology after two years of hard work, recently completed the WZL-3-type vacuum brazing, gas quenching furnace research mission, the Commission identified by the Science and Technology Commission, has been delivered to the original space department 23 used. The successful development of WZL-3 shows that China’s brazing and heat treatment with high vacuum furnace design and manufacturing technology has taken another step forward. It has the following characteristics: 1. Heater divided into three groups, sub-district regulation and control of temperature, the average temperature range, temperature range is small; 2. Inflatable, forced circulation cooling gas quenching system designed, does not affect
