Improving the Junction Between the Hot-Blast Main and the Bustle Pipe of a Blast Furnace

Abstract

Alternatives of hot-blast supply to the bustle pipe and the geometry of the tuyere stocks as one of the causes of nonuniform hot-blast distribution are discussed. Rational junctions between the hot-blast main and the bustle pipe and rational combinations of designs of junctions between the bustle pipe and the hot-bustle main and the blowpipe that minimize the nonuniformity of the hot-blast distribution are proposed.
