Abstract
1435888 Ore reducing furnaces VEREINIGTE OSTERREICHISCHE EISEN UND STAHLWERKE ALPINE MONTAN AG 21 Feb 1975 [22 Feb 1974] 7315/75 Heading F4B [Also in Division C7] Apparatus for reducing iron ore comprises a rotary kiln discharging into two hearth furnaces arranged in series, the three units being gastightly connected so that all exhaust gases are discharged through the kiln. In the particular embodiment described kiln 3 fired by burner 15 discharges into the first of two hearths (7, 8) formed in a common shell which is arranged to tilt about the axis of the kiln. The hearths are each provided with a tapping spout 18, and are separated by a weir 19 which is downwardly stepped on the side remote from the spout whereby by tilting in one direction slag or metal can be discharged, and by tilting in the other metal can be transferred from the first to the second hearth. The first hearth is heated by burners 9 or electrodes 17 to melt the charge, while in the second hearth slag-forming additions from hoppers 11, 13 are melted by electrodes 12 and the bath is then blown with oxygen from lance 14.
