PROCESS FOR TREATING METALLIC STARTING MATERIALS FOR SMELTING PLANTS,PARTICULARLY IRON SPONGE PARTICLES |
摘要 |
For protecting iron sponge particles against reoxidation and/or corrosion a coating comprising CaO as well as iron or iron oxides as adhesion promotor is applied onto the iron sponge particles. Water is subsequently sprayed onto this coating whereupon a second coating of a mixture of dust-shaped CaO and a carbon carrier is applied. This second coating is subsequently humidified with a smaller amount of water than would be necessary for completely slaking the CaO contained within the second coating. |
