process to convert steel slag into fertilizers

  • Slag As A FertilizerChestofBooks

    •The slag from the Thomas-Gilchrist process for making steel has long been supposed to have valuable properties as a manure. In the Bessemer converter there is a lining of lime which in the process of manufacturing the steel takes up a large percentage of phosphorus in the form of phosphoric acid.

  • Bessemer processWikipedia

    The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.

  • PRODUCING STEEL THROUGH THE MODERN CONVERTER PROCESS

    This part of the process is monitored very carefully until the percentage of carbon is reduced to the correct level according to the type of steel required. The waste (called slag) floats to the top and is poured off before the molten steel is poured. The molten steel is poured into moulds forming blooms .

    Converter slag is produced during the conversion of pig iron into steel in a basic oxygen furnace. For this reason it is also called BOF-Slag or LD-slag after the Linz-Donawitz process (1)(2). On average 126 kg converter slag is produced per ton of steel (3) with worldwide steel production of

  • Converting (metallurgy)Wikipedia

    Converting is a type of metallurgical smelting that includes several processes the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag as in the case of copper and nickel converting. A now-uncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.
