Abstract:Since the 350-ton tilting furnace was built and put into operation in August 2003 in Guixi Smelter of Jiangxi Copper, due to the increasingly rise of complex raw materials and the change of production technology, the production is restricted. After accumulating a great deal of experience in production practice, according to the influence of complex raw material proportioning and operation cycle,the influencing factors are analyzed. Through practice and operation, the operation efficiency of tilting furnace is greatly improved, the unit consumption of heavy oil is reduced, and the effect of energy-saving, emission-reducing, cost-reducing and efficiency-increasing is achieved, it is helpful to the sustainable development of "green smelting" of the factory.
