Abstract
PURPOSE:To control blasting conditions and clarging conditions of a blast furnace by using the shape of the meltzone in a furnace in accordance with the distribution states in the radial and circuitmferential directions of the ore weight/ coke weight ratio in the furnace determined directly with magnetic detectors. CONSTITUTION:In the shaft part of a blast furnace, >=1 piece of sensors are provided insertably into the charging materials in the furnace, and the distribution data in the radial and circumferential direction of the gaseous temp. and gaseous compositions in the furnace are determined. Thence, >=1 piece of magnetic detectors are provided insertably into the charging materials in the furnace incidentally to these sensors or separately therefrom, and the distribution data in the radial and circumferential directions of ore/coke are directly determined with these detectors. next, the infurnace conditions such as gaseous flow distributions, heat patterns, or reduction rates of are, etc. in the furnace are estimated by using these data, and at least either one blasting conditions such as the blast flow rate of tuyeres, auxiliary fuel blow rate, etc or charging conditions is changed by the results of said estimation. As a result, the blast furnace is operated stably and efficiently.
