  • Iron and Steel Slag Statistics and Information

     · Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron the blast furnace is charged with iron ore fluxing agents usually limestone and dolomite and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides silica and alumina. From this and the added fluxing agents molten slag and

  • Hand Forged Solid Wrought Iron Master Blacksmith

    Wrought iron is so named because it is worked from a bloom of porous iron mixed with slag and other impurities. The word "wrought" is an archaic past tense form of the verb to work. As irregular past-tense forms in English have historically been phased out over long periods of time wrought became worked. Wrought iron literally means worked iron.
