Furnace permeability was expected to limit the ability to reduce coke rate any further. In addition, the relative cost of coal would be significantly lower than the cost of coke it replaced. This lead to the decision late in 1991 to install pulverized coal injection (PCI) equipment for all of Inland`s blast furnaces.

After the two oil crises, all of the 42 blast furnaces operating in Japan stopped injecting heavy oil by August 1982, and pulverized coal injection (PCI), which was first introduced at the No. 1 Blast Furnace of Nippon Steel''s Oita Works in June 1981, spread rapidly. By 1998, PCI was applied to all of the blast furnaces in the country,
