我厂是采用密闭鼓风炉炼铅锌的大型有色冶炼厂,鼓风炉主体部分引用了英国ISP技术专利图低。原设计规模为年产铅锌金属5万吨,电银25吨,硫酸11.6万吨。自1975年试生产后至1984年底止,十年共产电铅11.6万吨,精锌21.4万吨,硫酸48.5万吨,电银209.13吨,产品品种由原设计的7种逐步发展增加至16种,上交国家税利12916万元。我厂的建设恰逢十年动乱,技术引进也仅是买了200多张图纸,设计、施工与设备制造
Our factory is a large-scale non-ferrous smelter using lead-zinc in a closed blast furnace. The main part of the blast furnace is quoted by the UK as a low-profile ISP technology patent. The original design scale for the annual output of lead-zinc metal 50,000 tons, 25 tons of silver, sulfuric acid 116,000 tons. Since the trial production in 1975 to the end of 1984, a total of 116,000 tons of lead per day, 214,000 tons of refined zinc, 485,000 tons of sulfuric acid and 209.13 tons of electric silver were produced over the past 10 years. The product variety has been increased from seven kinds of gradual development of the original design to 16 species , Handed over the national tax profit 129160000 yuan. The construction of our factory coincides with the turmoil of ten years and the introduction of technology has only bought over 200 drawings, designs, construction and equipment manufacturing
