    Basics Of Slag Production Article On The Slag Industry

    Oct 27, 2011 In tonnage terms, blast furnace slag is at present the main type followed by slags from the Basic Oxygen Steelmaking (BOS) and Electric Arc Furnace (EAF) processes. Various other processes such as external desulphurisation of steel may generate significant amounts of slag at some plants but overall they are only a small proportion of the total.

    The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in integrated steel plants using a version of the basic oxygen process or in specialty steel plants (mini-mills) using an electric arc furnace process.

  • Production and Properties of Basic Slag International

    Production And Properties Of Basic Slag International

    Basic slag is a by-product of the steel industry. In the steelmaking process the impurities in the crude iron are oxidised and together with lime form the slag. This slag which contains the phosphorus in the form of silicophosphates is ground to a fine powder. Traditionally ball or tube mills are used, but recently in this country a new Aerofall mill has been installed, in which the slag is mainly self-grinding.
