一 问题的提出 我厂缸套铸造使用一座2吨/小时热风两排大间距冲天炉。离心铸造机17台。班产毛坯在1400只左右,供三条机加工生产线用毛坯。由于企业上能力,又新增了一条机加工生产 线。所以毛坯产量满足不了生产线的需要。为了四条机加工生产线正常运转。毛坯产量要增加到班产2000只以上,只能从冲天炉开炉时间由原来的8小时,延长到16小时,离心铸造采用两个班次。
A question put forward I cast a cylinder using a 2 t / h hot air two rows of large cupola. Centrifugal casting machine 17. Class production of about 1,400 rough for three production lines with rough machining. Due to the company’s ability, but also added a machining line. Therefore, the production of rough can not meet the needs of the production line. In order to four machine processing production line normal operation. Blank production to increase to more than 2000 production class, only from the cupola furnace open time from the original 8 hours, extended to 16 hours, centrifugal casting using two shifts.
