Study on the Key Technologies of Direct Reduction for Rotary Hearth Furnace Dealing with carbon containing pellets

摘要

The current development of derect reduction technology for rotary hearth furnace (RHF) is introduced. It is essential to stable and continuous operation of the RHF carrying out the following technologies: the cold-pressing technology, design of the charging machine and discharging machine of the RHF, temperature, pressure and atmosphere in the furnace, and the antioxidation of the metallized pellets. The current develop situation of these technologies are fully discussed.
