A blast furnace is an aggregate in which cast iron smelting is determined by the interaction of a column of charge materials moving from top to bottom and an gas counter flow stream.
The nature of the gases movement over the cross section of the furnace shaft depends on:
- quality of charge materials;
- distribution of charge materials on the top;
- method of gas supply and removal.
