Low Fuel Rate Operation of the Blast Furnace

Test Operation with 100% Agglomerated Ore

Abstract

No. 6 Blast Furnace at Chiba Works of Kawasaki Steel Corporation, Japan's first large blast furnace equipped with Bell-less charging equipment, started its operation. The Bell-less top charging techniques have been completed with fundamental experiments and operational experience in this blast furnace. In July, 1979, test operation using burden composed fully of agglomerated ore (sinter and pellets) was performed for further operational stabilization. As a result, No. 6 Blast Furnace set the record of 429kg/t in low fuel rate operation of the large blast furnace with Bell-less top.
