Slakken kunnen op verschillende manieren worden geclassificeerd

Slag can be classified using different methods. Based on the ratio M of alkaline oxide (CaO+MgO) to acidic oxide, slag can be divided into alkaline slag (M>1), neutrale slakken (M=1) en zure slakken (M<1); According to the type of smelting pig iron, it can be divided into cast iron slag (slag discharged during the smelting of cast iron), steelmaking pig iron slag (slag discharged during the smelting of pig iron for steelmaking), and special pig iron slag (slag discharged during the smelting of pig iron with iron ore containing other metals, such as manganese slag and magnesium slag); According to the cooling method, physical properties, and appearance, it can be divided into slow cooling slag (block like, powder like) and rapid cooling slag (granular, fibrous, porous, and pumice like).
