Blast Furnace Slag

Ground-granulated blast furnace slag is used as a raw material for cement production! Coking plant. Coke, which consists mainly of carbon, not only supplies the necessary heat by burning but also serves in a special way as a reducing agent so that the iron can be removed from the ores! The chemical processes are discussed in more detail in the chapter on blast furnace processes.

Slag Cement

The bosh is the hottest part of the furnace because of its close proximity to the reaction between air and coke. Molten iron accumulates in the hearth, which has a taphole to draw off the molten iron and, higher up, a slag hole to remove the mixture of impurities and flux.The hearth and bosh are thick-walled structures lined with carbon-type refractory blocks, while the stack is lined with ...
