在批林批孔运动的推动下,为适应轴承工业飞跃发展的大好形势,在厂党委领导下及兄弟单位支持下,发扬自力更生的精神,自己动手建造了一条履带式淬火清洗回火自动线。该线具有连读生产、产量高、质量稳定、机械化水平较高的特点,是轴承工业热处理工序比较好的设备。这条自动线是在学习兄弟单位同类型设备的基础上结合本厂特点加以改进建成的。在电路供电部分,采用了可控硅无触点开关代替了磁吸开关,因而没有使用磁吸开关时往往因电压不稳定而出现故障多、噪音大的不良现象。其它同型设备淬火加热炉中三个
Under the impetus of the pro-Lin bidding exercise, in order to meet the excellent situation of the rapid development of the bearing industry, under the leadership of the factory party committees and the support of the fraternal units, the Company advocated the spirit of self-reliance and established a self-made track-type quenching and tempering automatic line. The line has a continuous read production, high yield, stable quality, high level of mechanization, bearing the industrial heat treatment process is better equipment. This automatic line is based on the same type of equipment learning brothers units combined with the characteristics of our factory to be improved built. In the circuit power supply part, the use of SCR non-contact switch instead of the magnetic switch, so do not use the magnetic switch is often due to voltage instability and more failures, noise, bad phenomenon.
