Abstract
Regardless of the type of raw material, it easily controls the segregation of raw materials that accumulate in the blast furnace. [Solution] The raw material segregation control device 10 controls the segregation of raw material 203 within the furnace top bunker 20 as it is loaded into the furnace top bunker 20. The raw material segregation control device 10 includes a raw material property measuring device 12 that measures the property values of the raw material 203 being transported to the furnace top bunker 20, and a control device 11 that controls the inclination angle of a segregation control plate 30, which is rotatable around a horizontal axis, from the horizontal plane based on the property values of the raw material 203 measured by the raw material property measuring device 12.
