Steel making today and tomorrow Hybrit

Iron ore in the form of fines is normally processed in sintering plants into sinter, and in some cases in pelletizing plants to iron ore pellets. Iron ore sinter and pellets are then charged together with coke from the top of the blast furnaces. Pulverised coal, oxygen and hot blast air are injected through tuyeres in the lower part of the blast furnace. Molten iron (called hot metal) and slag are tapped regularly from the .

corrosion in cast iron in water treatment: graphitisation ...

Cast iron corrosion resistance is comparable to that of carbon steel or even better depending on the alloy content. In view of the high carbon content, graphite, which is cathodic compared with iron, forms in the alloy microstructure where it can be found as chips (grey iron) or nodules (ductile iron) depending on its composition and heat treatment.
