摘要

Pohang No. 1 Blast Furnace is the oldest and smallest blast furnace in POSCO, which started its third campaign in 1993 and is operating steadily. This paper introduces recovering cooling capability of the old blast furnace to extend the campaign and the increasing cost-competitiveness of the small blast furnace by low-grade coke operation. For recovering cooling capability, a cooling water induction device was developed outside the shell and prevented damage to the body refractories by increasing body press-in hole. Pohang No. 1 Blast Furnace also succeeded in reducing the cost difference with large blast furnace through the low-grade coke operation.
