Coking coal cost surge worst for Chinese mills. In China, the surge in coking coal costs appeared to worsen, with the raw material making up between 50%70% of the input costs to produce hot metal, according to a recent market survey by Platts. A source at a steel mill in Shandong told Platts that the mill's estimated cost of coking coal had ...

Fig 1 Typical flow sheet of pulverized coal injection in blast furnace. The process of coal injection. The PCI process is based on the simple concept of carrying the finely ground (pulverized) dried coal by a conveying gas (normally nitrogen) to the BF where it is distributed to different tuyeres and injected through a lance in the blow pipe.

to depend on coal quality. PCI rates of 200 kg/t HM are just like that practicable, earning you a little fortune of 180 kg coke/tHM plus the carbon footprint involved. What is more, stateoftheart technology by Küttner enables you to markedly increase PCI rates and benefit from lower raw material costs and higher productivity.

ABSTRACT Partial substitution of pulverized coal (PCI) by renewable biocarbon for blast furnace injection is a practical approach to reduce GHGs in the steel production sector. For using biocarbon as feedstock, it is critical to measure its grindability to understand its milling behavior compared to that of typical PCI coal, and thus help decide on adjusting grinding process of existing ...

Grindability Index around 80. As these coals are very easy to mill, there will be savings from reduced mill power consumption for a given coal throughput. Low volatile coal also allows the mill capacity to be increased up to 40% above that of a 50 Hardgrove Grindability Index coal, thus allowing the steelworks to increase

Before injection, coal is ground to a fine powder of around 80% < 75 μm (termed PCI pulverised coal injection) or to a granular powder of around 95% < mm (termed GCI granular coal injection). PCI is the dominant system favoured by Asian and most European steel mills but GCI has been in successful operation in British and USA mills.
