BLAST FURNACE INSTALLATION.

摘要

A blast furnace installation comprises a blast furnace and a chute transmission gearbox (20); the blast furnace comprising a top cone (12) with a top cone ring (24) arranged thereon for receiving a connection flange (28) of the chute transmission gearbox (20). The connection flange (28) is directly fixed onto the top cone ring (24) by fixing means (32) for establishing a firm connection between the top cone ring (24) and the connection flange (28). According to an aspect of the present invention, the connection flange (28) is fixed to the top cone ring (24) in three separated fixation regions (30, 30', 30''), each fixation region (30, 30', 30'') comprising one or more fixing means (32). According to a further aspect of the present invention, the blast furnace installation also comprises a flexible sealing element (36) arranged around the perimeter of the connection between the top cone ring (24) and the chute transmission gearbox (20).
