Abstract
1440221 Shaft furnace GEORG FISCHER AG 28 June 1973 [28 June 1972] 30928/73 Heading F4B A gas-fired or oil-fired shaft furnace for melting and superheating a metallic charge has a shaft portion 12, a refractory insert 2 within a hearth 5 and burner nozzles 7. The hearth comprises a bottom 8 and an annular wall 30, 34. The insert supports charge material 4 and deflects burner gases 3 into the charge 4. The charge melts in the zone between the insert surface 10 and wall 30 and is superheated lower in the hearth. Molten charge material is removed through an outlet aperture 9. The insert has a conical grooved surface and may be of one-piece or multi-piece construction. The surface grooves may be straight or arcuate. To accelerate melting there may be additional burner nozzles 21 or apertures through which burner lances can be inserted.
