Iron making is a process that isolates and extracts iron from iron ores.  Cokes from dry distilled coking coal and the sintered ore baked in appropriate size are transported together to the blast furnace, where they are melted.

Steel making is a core process that determines the quality of steel products.  The melted iron that passed through the pig iron pre-treatment is blown in the combined blowing furnace.  Then it passes through cutting-edge refining facilities, such as vacuum degasser, power injection, and ladle furnace, finally coming out as steel with desired composition.
