个旧市有色金属加工厂,利用小反射炉(6.24米~2)熔炼铅锡混合矿生产焊锡,已有多年历史,实践证明,生产工艺成熟,技术可靠,流程简练。其主要工艺是:反射炉熔炼生产粗焊锡合金—精炼锅精炼浇铸成阳极—硅氟酸电解除杂—阴极片浇锭出厂。该焊锡产品质量高,1986年被评为部优产品,畅销国内外,取得了较佳经济效益。反射炉熔炼铅锡混合料,烟气量大,在炉内高温作业下,铅、锡、锌和其他低熔点的金属及化合物挥发率高,铅锡尘一般在6
Gejiu non-ferrous metals processing plants, the use of small reverberatory furnace (6.24 m ~ 2) smelting lead-tin mixed ore production of solder, has many years of history, proved that the production process is mature, reliable technology, process concise. The main process is: Refining furnace smelting crude solder alloy - Refining casting furnace refining anode - Silicofluoric acid electrolysis impurity - cathode tablets poured ingot factory. The solder products of high quality, in 1986 was named Buyou products, popular at home and abroad, and achieved better economic returns. Refined furnace smelting lead-tin mixture, a large amount of flue gas, high temperature operation in the furnace, lead, tin, zinc and other low melting point metals and compounds high volatility, lead tin dust is generally 6
