SKS lead smelting method, Ltd. is a Hunan Nonferrous metal SKS Group independently developed a new type of patent rights lead smelting process. The Shuikoushan smelting lead method belongs to the molten pool smelting category. When the material is put into the furnace and the heating, melting, oxidation, slagging and smashing processes are completed at the same time, it has a high mass transfer and heat transfer function; the difference is that it The Shuikoushan melting furnace is a unique and simple equipment with superior metallurgical dynamics. The charge is added from the top of the smelting furnace, and the bottom is fed with oxygen-enriched air to stir the molten pool. The smelting process is completed in the molten pool to produce crude lead, high lead slag and flue gas, respectively, from the lead discharge port and the slag discharge port. The exhaust vent is discharged. SKS closed melting furnace is a horizontal elongated cylindrical converter, magnesium chrome steel shell lined with brick, the furnace body has gear rotatable with the feed port, exhaust port, the slag discharge port, the discharge port of lead, the bottom The oxygen lance is installed, the oxygen lance and its set of bricks can be replaced, and the end wall fuel burner is used for opening and heat preservation. The Shuikoushan lead-smelting method is a continuous molten pool smelting and blowing process. It is a mixture of 6-7% lead-containing material and flux, which is continuously and uniformly added to the bottom of the oxygen lance equipped with a jet lance. In the blowing furnace, the materials are dried, melted, oxidized and slag-forming, and the lead-lead process is completed to realize separation of slag lead, and crude lead, flue gas and smelting slag are produced. Produce flue gas with high concentration of SO2, stable composition and flow rate, and acidification after purification. The main reaction equation is as follows: Oxidation slagging reaction: 2FeS + 3O2 + SiO2 = 2FeO•SiO2 + 2SO2 2ZnS + 3O2 = 2ZnO + 2SO2 2PbS + 3O2 + SiO2 = 2PbO•SiO2 + 2SO2 2PbS + 3O2 = 2Pb + 2SO2 2Pb + O2 = 2PbO PbS + 2O2 = PbSO4 Lead-lead reaction: PbS +O2 = Pb + SO2 2PbS +O2 = 2PbO + 2SO2 PbS +2PbO = 3Pb + SO2 Since its establishment, the company has always insisted onSurvive by quality and develop by reputation Snack Food Production Line,Snack Food Production Line Fresh Potato Chips Production Line,Snack Food Production Line Banana Chips Production Line,Snack Food Production Line Snack Bar Production Line Jump Machinery (Shanghai) Limited , https://www.shanghaimachineres.com
