Answer: The blast furnace is described as a counter-current solid or gas reactor, where the descending column of burden materials [such as iron ore, additives/fluxes, and coke] reacts with the ascending hot gases. This process is said to be a continuous one with raw materials that are being regularly charged to the top of the iron, slag, and furnace being tapped from the bottom of the furnace
