我们生产的~(3″)阀门的阀体模型材料是铜合金的,很苯重,仅一块双面阀体型板就重达30多斤,造型之后,连同沙箱就有100多斤,每天一个工人定额三、四十箱,劳动强度大,工人同志强烈要求改变这种落后的面貌。厂党支部根据群众建议,决定自力更生制造金属铝模型。我厂机械加工薄弱,生产周期长,废品率高,往往六、七十个毛坯,才能加工出一付型板,—度成为生产上的拦路虎。
The valve body model material of ~ (3 ") valve that we produce is copper alloy, it is benzene weight, only one double-sided valve plate weighs over 30 kilos. After modeling, it has 100 kilos per day A worker quota of three or forty boxes, labor-intensive, workers strongly urged the comrades to change this backwardness.According to the recommendations of the masses, the factory branch decided to rely on their own efforts to create metal aluminum model.Our factory machining weak, long production cycle, the rejection rate High, often six or seventy blanks, in order to produce a payboard, - degrees become a stumbling block to production.
