无产阶级文化大革命前,我厂反射炉的收尘设备,系采用人工震打方式,劳动条件很差,严重危害职工的健康;同时,技术经济指标也很落后,收尘效率只有92.5%左右,过滤速度也不过是12(米/时)。过去也曾对这台设备进行过改造,但未能彻底解决问题。1969年以来,我们组织了以老工人为主体的“三结合”攻关小组,广泛发动群众讨论,参考国内外收尘资料,从本厂实际情
Before the Great Proletarian Cultural Revolution, the dust collection equipment of the reflex furnace of our factory adopted artificial shaking method, and the working conditions were very poor, seriously endangering the health of workers. At the same time, the technical and economic indicators were also very backward with the efficiency of collecting dust being only about 92.5% Filtering speed is no more than 12 (m / h). In the past this equipment has been transformed, but failed to completely solve the problem. Since 1969, we organized a “three-combination” research team with old workers as the main body, extensively mobilized the masses to discuss and took reference from the dust collection materials both at home and abroad.
