四方机车车辆制造工厂沧口分厂铸铁车间,有一座焖火窑,由于设备较旧,操作不得法,经常影响产品质量。后来,经过苏联专家亲自到窑上观察研究,提出了全面的操作注意事项;该厂冶金科并据此制订了一个焖火的工艺规程。这个工艺规程从去年第三季度开始实行以来,焖火后的废品质量已经有了很大提高。但是,焖火窑上的部分工作人员,却对这一工艺规程不重视。他们虽然都知道工艺规程的具体内容,也表示过要遵照执行;但实际做起来 In the cast iron workshop of the Sifang Locomotive and Rolling Vehicle Manufacturing Plant, there is a bonfire kiln. Since the equipment is relatively old, operation is not allowed and the quality of the product is often affected. Later, after the Soviet Union experts personally went to the kiln to observe and study, put forward a comprehensive operational precautions; the plant metallurgical department and accordingly developed a bonfire process specification. Since the third quarter of last year, this process regulation has been implemented, and the quality of waste products after the bonfire has greatly improved. However, some workers on the bonfire kiln did not attach importance to this process. Although they all know the specific content of the process regulations, they also said they have to follow the implementation; but actually do it.
