我厂是用立式半连续浇铸方式生产变形铝合金坯,对于小直径的锭坯来说这方式存在如下缺点:①因直径小不能用浮简自动控制液流,氧化物易于混入锭内,影响质量;②因立式浇铸机行程短铸锭长度只有2—3米,这样相对切头尾料多,工作量大;③浇铸时生产率低,劳动强度大。我厂工人决心改革工艺,为国家节约人力物力。在批林批孔运动的推动下,同志们认真学习了毛主席的“自力更生,艰苦奋斗”的教导及党的“多快好省地建设社会主义”的方
I plant is the production of semi-continuous vertical casting deformation of aluminum alloy billet, for the small diameter billet this method has the following disadvantages: ① small diameter can not be used to automatically control the flow of floating Jane, the oxide is easy to mix into the ingot, Affect the quality; ② due to vertical casting machine trip length is only short 2-3 meters, so the relative cutting tail more, the workload; ③ low productivity when casting, labor-intensive. I plant workers determined to reform the process for the country to save manpower and resources. With the motivation of the “pro-xin-dong” campaign, comrades have conscientiously studied Chairman Mao’s teachings of “self-reliance and hard work” and the party’s principle of “building socialism more efficiently and economically”
