一、前言 葫芦岛锌厂目前锌的生产能力已达33万t/y,其中蒸锌21万t/y、电解锌13万t/y。葫芦岛锌厂现有鲁奇式沸腾炉9座,炉床总面积310M~2。承担着蒸锌和电锌所需焙烧矿供给任务。长期以来沸腾炉焙烧强度为6.5～7.0t/m~2·d。酸化炉为5.5～6.0t/m~2·d.由于酸化炉面积不足,为满足电解锌生产每年需要外购大量酸化矿。外购矿质量不稳定且价格较贵,直接影响生产和经济效益。近几年来,工厂围绕提高酸化炉焙烧强度做了大
I. Introduction Huludao Zinc Plant currently produces 330,000 t / y of zinc, including 210,000 t / y of zinc and 130,000 t / y of electrolytic zinc. Huludao Zinc Plant existing Lurgi boiling furnace 9, a total hearth area 310M ~ 2. Undertake the task of roasting ore supply required for steamed zinc and zinc. Long-term roaster boiling intensity of 6.5 ~ 7.0t / m ~ 2 · d. The acidifier is 5.5 ~ 6.0t / m ~ 2 · d. Due to the lack of acidifier area, a large number of acidified ores need to be purchased each year for the production of electrolytic zinc. The quality of the purchased ore is unstable and the price is relatively expensive, which directly affects the production and economic benefits. In recent years, the factory has made great efforts to improve the roasting strength of acidification furnace
