A Direct Method to Monitor Circumferential Imbalance in Burden Distribution for Blast Furnace

Abstract

This note describes a method to determine an imbalance in burden distribution by quantifying the ratio of coke and ferrous burden across the circumference of the blast furnace. Real-time signals of hopper weight, the tilt angle of the rotary chute, the rotation angle of the rotary chute, and the gate opening from bell less top system of the blast furnace is used as input data for this method. The imbalance in burden distribution can be seen as non-uniformity in the distribution of coke and ferrous burden across the circumference of the furnace. Few possible remedies to rectify the root cause of non-uniformity in burden distribution are discussed based on observations from an analysis of real-time signals from the bell less top system.
