Abstract

1385549 Charging bells for blast furnaces ISC SMELTING Ltd 12 March 1973 [25 May 1972] 24780/72 Heading F4B Bell and hopper charging gear for a blast furnace comprises at least two pairs of aligned vertical vanes 3 and 5, vanes 3 being attached to the bell 4 and vanes 5 to the lower frustoconical section of the hopper 1, the vertical height of the vanes 3 being greater than the distance of the bell travel. There may be three pairs of vanes disposed at 120 degrees to one another or four pairs disposed at 90 degrees to one another and the clearance between facing edges of each pair of vanes is less than one inch at operating temperatures preventing undue tilting of the bell.
