<p>According to the present invention, extreme very fine light is required to be used due to depletion of high-grade ore which is used as mineral for manufacturing conventional sintered ore. However, if a large quantity of extreme very fine ore is charged to a flow reducing furnace, the present invention is to resolve a problem of forming a stagnation layer in the internal of the flow reducing furnace by the interaction between very fine ore and weakening the flow of a pipe connecting a charging tube for connecting a flow path in a charging hopper and a multi-stage flow path.</p> |
