METHOD FOR PRODUCING PELLET AND METHOD FOR SMELTING NICKEL OXIDE ORE |
摘要 |
Provided is a method for producing a pellet capable of suppressing heat shock-induced crack occurrence, when nickel oxide ores are made into pellets and placed in a reducing furnace in a smelting process. In the method for producing a pellet from a nickel oxide ore, a nickel oxide ore, a binder and a carbonaceous reducing agent are mixed, the mixture is made into a lump, and then the resulting lump is subjected to a preheating treatment at a temperature of 350 °C to 600 °C. In this preheating treatment, the lump more preferably undergoes the preheating treatment at a temperature of 400 °C to 550 °C. |
