Background

The oxygen-enriched bottom blowing copper smelting technology is also called a water gap mountain copper smelting method (SKS method), is expanded based on the water gap mountain lead smelting method, and is another enhanced molten pool smelting new technology independently developed in China after the silver copper smelting method; patented in 1992, the technology was first applied to the annual 1 million ton cathode copper project in the great dragon smelter in vietnam in 2006, and was subsequently successfully applied to two smelters, eastern circle of america and henbang, one after the other. A qualitative and quantitative leap is achieved over a period of more than ten years. At present, 15 copper smelting enterprises in China adopt the technology to produce. The oxygen bottom-blowing lead smelting technology is continuously improved and promoted since the first production line is put into production in 2002, remarkable performances are achieved in the aspects of raw material adaptability, energy conservation, emission reduction, clean production and the like, and more than 40 production lines adopting the oxygen bottom-blowing lead smelting technology are available through more than ten years of market inspection. The oxygen-enriched bottom-blowing smelting industrial success application opens a new era of non-ferrous metal smelting or noble metal trapping smelting with copper and lead as carriers.

The furnace body is provided with a charging port, a smoke outlet, a slag tap, a matte (copper) tap and a detection hole, the bottom of the furnace body is provided with an oxygen lance, and the end wall fuel nozzle is used for blowing and heat preservation. The oxygen lance is a vital part of a bottom blowing smelting furnace, and the basic structure is in a multi-layer sleeve form. The inner pipe is filled with pulverized coal and carrier gas, and the middle part is filled with oxygen for supplementing heat and providing oxygen for reaction; the outer pipe is filled with nitrogen or compressed air for cooling and protecting the oxygen lance.

Because the bottom-blowing smelting furnace is a cylindrical rotary metallurgical furnace, the diameter of the bottom-blowing smelting furnace cannot be too large under the conditions of processing of rolling rings and gear rings and stress of carrier rollers, the maximum specification of the bottom-blowing smelting furnace put into production in the world is 5.8 x 30 meters at present, and the bottom-blowing smelting furnace is the shortest distance between a melt surface and a charging hole in the copper smelting and lead smelting industries using the formed scale at present. Therefore, the biggest short plate of the bottom-blowing smelting technology is that the strong stirring of the high-pressure gas to the melt through the oxygen lance inevitably causes part of high-temperature melt to splash upwards to the charging opening, the high-temperature melt or the materials in the mixed falling process of the high-temperature melt form bonding along the periphery under the charging opening, and the charging openings of the oxygen bottom-blowing smelting furnaces at home and abroad at present mostly adopt water-cooling structures for protecting the refractory materials at the periphery.
