Blast furnace slag can be obtained in four different ways: (1) Air-CooledBlastFurnace Slag: The liquid crucible is flooded onto the slag bed and slowly cooled at ambient temperature to form hard block crystals, which can then be crushed and sieved to obtain products of different particle sizes. (2) Expanded and Foamed Blast Furnace Slag (ExpandedorFoamedBlastFurnaceSlag): If the molten blast furnace crucible is cooled by the addition of controlled water, air or steam, the cooling and solidification process will accelerate, producing a lightweight expanded or foamed product. Puffed blast furnace slag differs from slow cooling slag in its relatively high porosity and low bulk density. (3) Pelletized Blast Furnaces Slag: If the molten blast furnace is cooled and solidified in water and air in a rotating drum, a non-solid blast furnace slag ball can be obtained. By controlling this process, the flooding can be fully crystallized, suitable for use as an aggregate, or the slag can be formed into a glassy state, thereby being suitable as a cement raw material. The faster the cooling rate, the more the glass phase, the less the crystalline phase. (4) Granulated BlastFumace Slag: If the molten water is rapidly cooled and solidified, most of the slag becomes amorphous with little or no crystalline state. This process produces sand slag particles. The physical structure of the slag particles and the grading of the granulated slag depend on their chemical composition, temperature and water quenching time, and production method. If the granulated blast furnace slag is ground to the size of the cement particles, its hydraulic property is very suitable as an Additive for cement.
