Abstract Scope The roller hearth furnace(RHF)is applied in high nickel cathode roasting process.Base on CFD analysis and operating data, the temperature and atmosphere inside furnace is not even in heat-up zone and holding zone. In order to improve homogenous and efficiency, oxygen lace and atmosphere control system was developed. The roasting process is examined and optimized by tests in RHF with different lance positions and oxygen injections. It can be concluded that the oxygen injections significantly enhance the reactions on the high nickel material. It is possible to draw a reaction picture inside the furnace, and one realizes that the reaction is the strongest at the beginning, and in the course of which the internal reactions increase. These subsequent reactions can also be influenced and optimized via the lances. The results prove the roasting process have space for further upgrade and reduce cost by utilize energy for heat up.
