    LEGO IDEAS - Product Ideas - Blast Furnace

    At the base of the furnace are two exits. The slightly higher located one is to extract the waste product, the slag. This flows into a slag ladle for further transport. Slag is often used for driveways. The lower located exit is used for the molten iron which flows to the torpedo wagon. It is then transported to an iron mill for further processing.

    Blast Furnace Slag | National Slag Association

    Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.

    Blast Furnace - HarbisonWalker International

    The blast furnace process has been the primary method for producing iron for many decades. The blast furnace is a refractory-lined circular shaft 100 to 200 feet high, with an internal diameter between 20 and 45 feet. The refractory wall lining typically measures two feet or more in thickness and contains more than 2,500 tons of refractories.

    Once the temperature and chemistry are correct, the steel is tapped out into a preheated ladle by tilting the furnace. For plain-carbon steel furnaces, as soon as slag is detected during tapping, the furnace is rapidly tilted back towards the deslagging side, minimizing slag carryover into the ladle.
