Evaluation of spent pot lining (SPL) as an alternative carbonaceous material in ironmaking processes

Evaluation of spent pot lining (SPL) as an alternative carbonaceous material in ironmaking processes

Integrated ironmaking plants equipped with blast furnaces utilize several types of carbonaceous materials for hot metal production. Among them, coal is used for cokemaking and PCI, being the most expensive raw material for primary iron production. Due to high costs, ironmaking plants are constantly...
