Blast Furnace with 6000 m3 Internal Capacity

POSCO expanded the internal capacity of Blast Furnace No. 1 from 3800 to 6000 m3 by mobilizing all different innovative engineering methods through the project. It is the world’s largest in scale that exceeds Chinese Shagang Group’s Blast Furnace No. 1 (5800 m3), which was previously the biggest. There are 21 large scale blast furnaces with a capacity of over 5000 m3 each worldwide. With the upgrading project, the annual steel production at Gwangyang Blast Furnace No. 1 increased from 3,28 Mt/a to 5,65 Mt/a. This is a volume enough to produce 5,65 million passenger cars yearly. Gwangyang Blast Furnace No. 1 has transformed into a blast furnace facility armed with eco-friendly functions, which not only preemptively prevents generation of steam but also enhances the energy recovery ratio and saves electricity consumption. Amid concern over excessive production due to a slump in the steel industry in recent months, POSCO plans to use molten iron generated at Gwangyang Blast Furnace No. 1 to produce high added-value products and replace scrap iron.
