Side-blown furnaces are important metallurgical equipment. Their core purpose is to intensify the smelting and reduction of materials by blowing oxygen-enriched air or fuel into the molten pool through side lances. With its strong molten pool agitation and rapid heat and mass transfer, it plays a crucial role in non-ferrous metal pyrometallurgical processes and comprehensive resource utilization.
In lead smelting, side-blown furnaces are commonly used to process liquid high-lead slag. They produce crude lead through reduction reactions and effectively capture precious metals, offering significant energy-saving and environmental advantages compared to traditional processes.
In copper smelting, oxygen-enriched side-blown smelting technology can directly process copper concentrate to produce copper matte, with high heat utilization and easy furnace control.
Furthermore, this technology has been extended to nickel smelting, used to process high-magnesium nickel raw materials and various tailings, improving raw material adaptability and smelting efficiency.
Another major application of side-blown furnaces is resource recovery and hazardous waste treatment. It effectively processes zinc leaching slag, recovering various valuable metals such as zinc, silver, lead, and copper, solving the problem of traditional processes being unable to handle such materials.
In the recycled lead industry, oxygen-enriched side-blown furnaces can be used to process lead paste generated from the dismantling of waste lead-acid batteries, achieving low-temperature continuous smelting with a high lead recovery rate, and the flue gas is easily used for acid production.
Furthermore, this technology has shown potential in processing complex tin materials, enabling efficient reduction and recovery of tin.
Overall, side-blown furnaces, with their strong material adaptability, low energy consumption, and good environmental performance, have become one of the core pieces of equipment in modern non-ferrous metal smelting and solid waste resource utilization.
