HOT BLAST MAIN CONSTRUCTIONS INCLUDING A JUNCTION

摘要

A junction in a hot blast main construction is formed between first and a second horizontal, circular hot blast mains. Each main has a steel jacket and inside the steel jacket refractory brickwork bounding a passage for the hot blast through the main. To achieve a simple construction, at said junction the steel jackets of circular cross-section of are coupled directly to each other without interposition of any intermediate jacket pieces and at the top side of both the first and second mains the brickwork is constituted by shaped bricks which are suspended from the steel jackets.
