DEVELOPMENT OF MONITORING SYSTEM FOR LUMP AND COHESIVE ZONES IN THE BLAST FURNACE.

Abstract

At No. 2 blast furnace of Sakai Works, an effort is being made to develop and apply new types of sensors (magnetometer, and gas flow meter) and probes (shaft diameter probe, shaft wall probe, etc. ) for accurate measurement of gas flow distribution and burden behavior in the lumpy zone. Mathematical models for estimation of the state of the lumpy zone and the outer profile of the cohesive zone in the furnace have been developed.
