生产任务翻番以后,毛坯的供应量大大的增加了,于是气割工作也增大了很多。但由于市上电石(乙炔)供应的困难,气割工作受到很大的影响。在这种情况下,我厂鍛工工段徐、楊两位师傅开动脑筋,研究成功用柏油、木屑和肥皂粉干餾后所得的气体来代替乙炔,从而解决了乙炔供应不足的問題。干餾过程干餾所用的設备如附图所示。工作时将預先敲成小块(約1/2″)的柏油(建筑道路用的普通柏油)12公斤、木屑(任何木屑均可)4公斤、肥皂粉0.5公斤混合均匀,从加料口加入爐中。每加料一层必須用鉄棒摏紧(料装得多,气
Doubled the production task, the rough supply has greatly increased, so gas cutting work has also increased a lot. However, due to the difficulty of supply of calcium carbide (acetylene) in the city, the work of gas cutting has been greatly affected. Under such circumstances, Xu and Yang, two of our factory’s forging workers, brains to solve the problem of insufficient supply of acetylene by successfully replacing the acetylene gas with the gas obtained after the distillation of asphalt, sawdust and soap powder. Dry distillation process equipment used in the dry distillation as shown in the figure. 12 kilograms of asphalt (common asphalt for construction roads), 4 kilos of sawdust (any sawdust may be used) and 0.5 kilograms of soap powder are mixed in advance into the furnace from the feeding port In. Each layer must be fed with a stick tightened (material loading much, gas
