当前国内外炼锡工业对含硫砷较高的锡精矿炼前焙烧均采用多膛焙烧炉或回转窑设备,而沸腾焙烧锡精矿尚未见到有关实践的报导。我厂于1965年在与昆明冶金研究所、广西冶金研究所共同进行的小型沸腾焙烧锡精矿试验基础上,建成床面积为1.77平方米的沸腾炉,取代原多膛炉,进行工业生产。 At present, the domestic and foreign tin-making industries use multiple-bake roaster or rotary kiln equipment for pre-smelting tin concentrate with higher arsenic and arsenic content, and boiling roasting tin concentrate has not yet been reported on practice. Based on the small-scale roasting tin concentrate test jointly conducted by Kunming Institute of Metallurgy and Guangxi Institute of Metallurgy in 1965, our factory built a boiling furnace with a bed area of ​​1.77 m2 to replace the original multi-hearth furnace for industrial production.
