Coal Grinding System In Blast Furnace

Injection of coal and waste plastics in blast furnaces

Injection of coal and waste plastics in blast furnaces 5 commonly carried out with only a few ironmaking plants in Japan and Europe currently injecting plastics The first attempts at WPI were made at the Bremen Steel Works in 1994 with commercial injection starting a year later The first integrated system for injecting plastic wastes was at NKK s now JFE Steel Keihin Works East Japan
