Abstract

1351830 Replacing furnace charging bells NIPPON STEEL CORP 20 Dec 1971 [21 Dec 1970] 58993/71 Heading F4B In a blast furnace, the top structure is divided into sections I, II and III comprising a shoot and hopper, a small bell, its seating and a hopper and a large bell and its seating respectively, the top two sections are fitted with axles and wheels, which may be removable, so that these sections may be wheeled on to platforms 16 and 17 respectively to enable the lower section III comprising a large bell and its seating to be readily replaceable. The platforms 16, 17 extend at right angles to a crane gantry 9, and the wheels are removable or resiliently mounted to enable the sections of the structure to be sealed together. The top structure may be divided into two sections only, and only one platform provided. Since the sections of the top structure above the larger bell can be quickly moved to one side to enable the large bell to be replaced, the furnace down time is reduced.
