METHOD FOR CONTROLLING CHARGE OF SINTERING RAW MATERIAL

PROBLEM TO BE SOLVED: To provide a control method for charging sintering raw material, with which the upper layer thickness is controlled to the constant without giving influence on a segregation state of the sintering raw material charged on a sintering pallet. SOLUTION: In order to classify fine a...

Summary:PROBLEM TO BE SOLVED: To provide a control method for charging sintering raw material, with which the upper layer thickness is controlled to the constant without giving influence on a segregation state of the sintering raw material charged on a sintering pallet. SOLUTION: In order to classify fine and small granular sintering raw material 18 (containing coke) from the sintering raw material 17, an opening part 3 is arranged in a charging chute 7 and also, a first nozzle 15 for blowing gas from the upper part of the opening part 3, is arranged. The fine and small granular sintering raw material 18 is dropped from the opening part 3 by blowing the gas onto the sintering raw material 17 from this first nozzle 15, and the flow rate of the blowing gas is controlled so that the layer thickness of the fine and small granular sintering raw material 18 on the sintering pallet 10, i.e., the upper layer thickness 13u becomes the preset value.
