2010年8月8日,工业和信息化部对2010年18个工业行业淘汰落后产能企业名单予以公告。要求有关方面要采取有效措施,确保列入名单企业的落后产能在2010年9月底前关停。这次涉及落后产能淘汰的锌冶炼企业产能普遍为火法炼锌,工艺采用竖罐蒸馏以及马弗炉冶炼等落后工艺。《产业结构调整指导目录》等产业政策规定中强调用土制马弗炉、马槽炉、横罐、小竖罐等进行还原熔炼再以简易冷凝设施回收锌等落后方式炼锌或氧化锌的工艺需要立即淘汰。
On August 8, 2010, the Ministry of Industry and Information Technology made a public announcement on the list of enterprises that have eliminated backward production capacity in 18 industrial sectors in 2010. Require relevant parties to take effective measures to ensure that the backward production capacity of enterprises listed in the list by the end of September 2010 shut down. The zinc smelting enterprises involved in the elimination of backward production capacity generally produce pyrolyzed zinc, and the process adopts backward process such as vertical tank distillation and muffle furnace smelting. Industrial policies and regulations such as “Industrial Structure Adjustment Guidance Catalog” emphasize the use of indigenous muffle furnace, horse tank furnace, horizontal tank, small vertical tank and so on reduction and smelting and then simple recovery of zinc and other backward methods of zinc or zinc smelting process Need to be eliminated immediately.
