Abstract

1,203,876. Charging blast furnaces. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. 19 March, 1968 [20 March, 1967], No. 13312/68. Heading F4B. In blast furnace charging apparatus of the double bell type a rotatable distributing hopper 3 has its bottom closed by a small bell 10 which is covered with a protective conical member 9. Guiding means comprising spaced slide bars 4 resting on a framework 5, and a counterbalance device permit vertical travel of the hopper 3, the vertical travel being limited by stops 8 and 8a integral with the framework 5 which rests on a raceway 7. A suspension device 2 incorporating coaxial tubular members permits the two bells 10, 18 to be independently raised and lowered as required to effect charging of the furnace. In the raised position the periphery of the small bell 10 presses against an annular seal 15. A pipe 16 allows gas from the furnace to escape to recuperators, a further seal 17 being provided to prevent gas exiting via the top of the furnace direct to the atmosphere. The lower end of the protective cone 9 is slightly outwardly flared for deflecting the charge clear of the lower edges of the small bell 10.
