Blast furnace equipment and blast furnace operation method

摘要

A swivel chute for charging raw materials from the top of the blast furnace to the inside of the furnace, which provides a blast furnace facility having a measuring means for accurately and quickly grasping the surface profile of the contents inside the furnace, and the swivel chute for loading the raw material into the furnace A profile measuring device for measuring the surface profile of the charged object and a tilt angle control device for controlling the tilt angle of the swivel chute are provided, and the profile measuring device is installed at the top of the furnace and inside the furnace. A radio range finder that measures the distance to the surface of the blast furnace, and the entire area inside the furnace with respect to the distance to the surface of the blast furnace obtained by scanning the detection wave of the range finder in the circumferential direction of the blast furnace. A calculator that derives a surface profile of the charged object based on the distance data over the range, and commands the tilt angle control device to change the tilt angle of the swivel chute during the swivel based on the obtained surface profile. A calculator that commands the speed control device to change the turning speed of the turning chute inside, and a calculator that commands the speed control device to change the supply speed of the charge to be supplied to the turning chute during turning. Have any one or more.
