Abstract

1,198,157. Cupola melting of iron. C.K. HEE. June 6, 1969 [June 13, 1968], No. 28069/68. Heading C7D. [Also in Divisions F3-4] A cupola furnace 1 is provided with lower cold combustion air main inlets 7 and above them, supplementary hot combustion air inlets 9. Heated air and combustion products, from one or more oil or coke fired auxiliary furnaces (Fig. 3 not shown) are tangentially supplied through lines 10 to refractory lined annular mixing chamber 8 surrounding the furnace 1, to pass into it through the inlets 9. Shaped refractory blocks 17 lining the chamber 8 ensure a uniform hot air distribution around the furnace periphery. Coke charged to the furnace is combusted by the cold air supply from main inlets 7, the heated supplementary air maintaining a high temperature fusion zone above the main combustion air inlet level. Slag and molten metal are tapped through outlets 6, 4 respectively. The hot air supplied is about 50% by volume of that of the cold air, and is heated to 900-1000‹ C. The power air supply may be enriched with or replaced by oxygen.
