铝包钢芯线的清洁生产

Clean production of aluminum clad steel core wire

针对原铝包钢芯线钢丝生产存在铅、废酸、废水污染,以及成本高、生产效率低等问题,对生产设备及工艺进行改造。采用压力模压力涂覆润滑工艺、新型电加热管式马弗炉、水浴淬火工艺装备、砂带磨削法去除氧化皮等措施,结果表明,改造前后两个月热处理工序总成本降低6.06万元,吨耗降低37.9元;包覆工序增加砂带磨削后,成本从506.02万元增加到537.86万元,避免了铅、废酸、废水污染,满足国家绿色环保要求。

Aiming at problem of lead, waste acid, waster water pollution existing in production of original aluminum clad steel core wire and cost high, production efficiency low and so on, production equipment and process is renovated, the measurement such as adopting pressure die pressure coating lubrication process, new electric heating tube type muffle fur- nace, water bath quenching equipment, abrasive belt grinding to remove the scale etc, results show that two months before and after renovation, heat treatment procedure total cost decreases 60.6 thousand yuan, consumption decreases 37.9 yuan per ton. After coating procedure adding abrasive belt grinding, cost increases from 5. 060 2 million yuan to 5. 378 6 million yuan, Lead, waste acid, waste water pollution is avoided, which meet national requirement of green environment protection.
