Our History AHMSAAdvised by the American Rolling Mill they decide to locate it in Monclova Coahuila for its proximity to deposits of coal and iron ore basic raw materials 1942 Altos Hornos de México was constituted in July of that year as a company with state and private capital Since 1941 equipment had been acquired in the USA including a blast furnace that was abandoned in Saint Louis Missouri The
Why Use Coke for Blast Furnace Ironmaking not Use Coal · In blast furnace ironmaking coal is not as strong as coke and crushing will cause a decrease in the permeability of the blast furnace The calorific value and carbon content of some anthracite coals are higher than coke but there are more harmful impurities such as phosphorus and sulfur in coal As the combustion enters molten iron the quality of subsequent steel will be affected
Pulverized Coal Injection in a Blast Furnace IspatGuru· Pulverized coal injection PCI is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace BF Pulverized coal is an important auxiliary fuel used in the BF ironmaking PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable It can result in substantial improvement in the
