摘要： A device (20) for replacing a blast furnace runner allows the runner (14) to be transported between an upper, tapping floor level (16) and a lower, service level (42). This handling device (20) comprises an inclinable bridge (26) that can support the runner (14) in an operational position in front of a taphole (12) of the blast furnace (10). This bridge (26) can be inclined so as to form an inclined plane along which the runner (14) can be raised or lowered. Thus, the runner (14) is transported along an inclined plane from the upper, tapping floor level (16) to the lower, service level (42) and vice-versa. ® KIPO & WIPO 2007
