以前,我厂铸铁车间使用的收集炉渣用的垃圾包是整体铸造的,这种垃圾包使用起来颇不方便,而且,炉清在包底“冻结”后难以自行脱落,需人工敲击包底才能使其脱落,这样,势必会影响包子的使用寿命和使用效率。后来,我们改进了垃圾包结构,采用无底式分体铸造、组合装配的方法制成了如图所示的垃圾包。 In the past, the rubbish bag used for collecting slag in our factory’s cast iron workshop was cast as a whole. This kind of rubbish bag was quite inconvenient to use. Moreover, it was difficult for the furnace to fall off by itself after it was frozen. In order to make it fall off, so, is bound to affect the service life and efficiency of the buns. Later, we improved the structure of the trash bag, using bottomless split casting, combined assembly method as shown in the trash bag.
