Abstract
1354628 Tuyeres CENTRE DE RECHERCHES METALLURGIQUES-CENTRUM VOOR RESEARCH IN DE METALLURGIE 28 Nov 1972 [30 Nov 1971] 54947/72 Heading F4B A tuyere for a shaft furnace has a longitudinal section with an inner tube 5 of non metallic refractory housing a smooth constant diameter bore and an outer tube 4 of metal such as stainless or alloy steel, a nozzle part 2 having a convergent part 7 followed by a parallel sided outlet 8, and a terminal part including a collar 10 for securing to the outer furnace wall, an inlet 15 and an outlet 16 for cooling liquid and a coolant circulating system comprising four tubes 23, 24 embedded in the refractory inner tube, two diametrically opposite tubes 23 being connected to an inlet manifold 17 in the terminal part and the other tubes 24 returning coolant through a manifold 18 in the terminal part to the outlet 16. Extensions 25, 26 of the coolant pipes are arranged within the nozzle, which may be of copper, to ensure the circulation. The terminal part has an inner refracting part 11 forming a continuation of the bore, which may be integral with the inner tube, and a metallic frusto-conical part connecting it to the outer tube 4.
