In 2018, the annual output of electrolytic copper in China was 9.029 million tons, an increase of 8.0% year on year, accounting for more than one third of the global total output, most of which were made by pyrometallurgy. Industrial furnace insulation board manufacturers believe that at present, about 80% of the global primary copper output is produced by pyrometallurgy, and about 20% is produced by hydrometallurgy. So far, pyrometallurgy has been the main copper smelting process, and industrial furnaces play a vital role.

The thermal insulation board manufacturer of industrial furnace believes that the technological process of copper smelting by fire mainly includes matte smelting (matte or matte), matte converting (crude copper), fire refining (refined copper) and electrolytic refining (pure copper). The difference between the industrial furnaces used in the whole process is mainly the smelting of copper matte, and the subsequent smelting and refining are roughly the same. China's copper production process not only includes all copper processes in the world, but also has its own good processes, such as silver copper smelting process, oxygen low blow smelting furnace, etc.

The insulation board manufacturer of industrial furnace believes that matte smelting can be divided into flash smelting and bath smelting. Flash smelting mainly includes the Otikun universal flash furnace, which was born in 1949, and the Canadian Inco flash smelting. The flash furnace can produce 300000 to 400000 tons of copper per year. The furnace body is composed of reaction tower, sedimentation tank and rising flue. The equipment can be divided into five parts: furnace steel structure fabrication, reactor tower installation, furnace cooling device installation, electrode device installation and auxiliary equipment installation.

The insulation board manufacturers of industrial furnaces believe that the furnaces used for melting pool mainly include Aisa method, Osmet method (Australia), Noranda method (Canada), silver method, etc. According to different air inlet modes, it can be divided into top blowing, side blowing and low blowing furnaces.

Isaac and Osmet, they are very close. The furnace is mainly composed of furnace body, spray gun, spray gun base, lifting device, rear burner, etc. The furnace body is 510m and the annual output of a single furnace can reach 200000 tons. It is a top blowing furnace.

Noranda process is a rotary horizontal cylindrical furnace, with steel shell lined with chrome magnesia bricks and a daily processing charge of 3000 tons. It belongs to side-blown furnace.

The insulation board manufacturer of industrial furnace believes that the Osmet furnace is formed on the basis of the original Siro smelting method and Essar smelting method and through the development of many application technologies. There is strong stirring and mixing between the melt, charge and gas in the molten pool, which greatly strengthens the heat transfer, mass transfer and chemical reaction rate. A sleeve is added to the outer layer of the spray gun, so that the secondary combustion air required in the furnace can be directly injected into the furnace shell from the spray gun, so that the metal vapor and unburned carbon particles above the molten pool can be fully burned and absorbed by the violently stirred melt, which greatly improves the thermal efficiency of the intracranial reaction and also greatly improves the nature of the flue gas.

The thermal insulation plate manufacturer of industrial furnace believes that the rotary anode furnace is mostly used for copper pyrorefining, and its process is to further remove sulfur and impurities from crude copper and cast it into anode plate to meet the needs of electrolytic refining. The furnace body is similar to the converter, which is mainly composed of the furnace shell, four supporting rollers supporting the furnace shell, large gears and transmission devices. The installation is mainly composed of several parts, such as the rotary device and supporting roller device, the furnace body, the furnace door opening and closing device, and the lubrication system installation and commissioning. The furnace body of formed products is about 4.312m. The processing capacity of the furnace is 100 tons, 200 tons, 300 tons, 400 tons, etc.
