Jul 01, 2011 There are many types of steel-slag, which are derived from the manufacture of different kinds of steel, the steelmaking conditions and slag dispatching process. Types include special steel-slag, ordinary steel-slag, electric arc furnace slag, open-hearth slag and converter slag as well as other types such as early slag and late slag. The dry process of cement manufacture is most often used, but some plants utilise the wet process, which avoids the necessity of drying the slag. In Germany the slag is used both in the manufacture of the Portland cement clinker by the dry process and for grinding subsequently with the clinker to form the Portland blastfurnace cement.

Read MorePortland cement manufacturing process can be divided into 6 steps raw material crushing, pre-homogenization, fine grinding, clinker production, cement grinding, cement packing, etc. In these processes, we need the assistance of different kinds of cement equipment, such as cement kilns, cement mills, and cement crushers. Sep 29, 2014 Most of the BF liquid slag gets granulated and is sold to cement manufacturers for the manufacture of BF slag cement. A small amount of BF slag gets air cooled. The air cooled BF slag is either dumped as landfills or used in road repairs within the steel plant. In either case the iron contamination of the slag is separated and sold for re-melting.

The process of cementitious cement production takes about three years and is expensive. The slag itself is used to make steel products, such as steel rails and steel pipes. A process for the production of Portland cement and white Portland cement using magnesium furnace slag, a waste product from the manufacture of magnesium metal, as a primary starting material. The furnace slag is blended with calcium oxide and silicon dioxide to form a feedstock which is heated to a temperature and for an amount of time sufficient to form clinker.
