INFLUENCE OF THE UP-THRUST ON BLAST FURNACE OPERATION

Liu Yuncai (Shoudu Iron & Steel Co.)  
A new concept in the force system of burden column in blast furnace, the up-thrust(UT), has been ra(?)sed in this paper. Its formation, variation and influences on BF operation and on iron and slag drainage are detailed. Source of UT is taken from the buoyancy to deadman partially immerged in the liqud. In BFs of intermittently taping type, the UT increases when iron and slag accumulates in hearth, and this may induce columm compression, higher blast pressure, lower blast volume, ron flow from slag hole and leakage of water jacket of slag hole. In order to stabilize UT, different drainage methods: continuous iron taping without upper slag, or intermitlent with controlled upper slag rate, are suggested, and the number of iron holes must be designed adequatly.
