<p><P>PROBLEM TO BE SOLVED: To continuously produce a blended raw material having constant components and properties as a raw material for a metal reducing furnace, in a process of blending dust with slurry containing an oxidized metal powder and a carbon powder with a wet process, even when the components and the properties of each raw material change with time. <P>SOLUTION: This wet blending method comprises selecting at least n+1 sorts of raw materials with respect to n pieces of indices expressing the properties of a raw pellet; determining the ratio of blending them through grasping the values of the corresponding n pieces of indices in each raw material; blending each raw material into the blending ratio in a raw material mixing tank; and then supplying it to a uniformizing tank. The supplying method comprises dewatering the mixed raw material produced with the above method into a dewatered product with a dewatering device, and producing the raw pellet by forming the dewatered product with a forming apparatus; and supplying it to the reducing furnace. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
