In August 2013, Salzgitter Flachstahl (SZFG), Germany, had awarded the Paul Wurth Group with a turnkey order for the construction of a pulverised coal injection (PCI) plant for Blast Furnaces ‘A’ and ‘B’ at their Salzgitter integrated steel plant. The plant started operation in spring 2015 and helps now to reduce the cost of ironmaking operations.
The plant features two coal grinding and drying plants of 50tons per hour capacity each. The injection plants are designed to reach a capacity of 200kg of pulverised coal per ton of hot metal. With the first coal having been injected into the BF ‘B’ in March 2015 and the readiness for operation achieved in April 2015, the respective contractual milestones have been accomplished.
