It is generally recognized that two key factors for enhanced blast furnace operations are maximum furnace productivity (thm/m3 centre dot day) and maximum pulverized coal injection (PCI) rates. In order to meet these operational coals, the furnace coke must have the following characteristics: High strength after reaction (CSR) High cold strength (stability, M40, 140, etc.) Large mean size, and Consistent coke quality Sun Coke Company, through 40 years of continual and ongoing technology development, has successfully developed its heat recovery cokemaking technology. This technology inherently produces furnace coke that meets the criteria listed above.
