In the whole smelting process the most important is the reduction of iron and slagging reaction. Although level 15 smithing is required to smith iron bars level 60 is strongly recommended so that you don t have to pay an entrance fee to the blast furnace.

Picture Blast Furnace Furnace History Of Steel

In furnace the charge is constantly moving slowing downward against the force flow of the very hot gases which bring about the evaporation of moisture from the charge at the top.

Smelting of iron in a blast furnace. The purpose of blast furnace smelting is to reduce iron from iron ore and remove impurities. In a blast furnace fuel ores and flux are continuously supplied through the top of the furnace while a hot blast of air sometimes with. It provides a great opportunity for players to reap great profits by producing a large volume of iron bars worth 137 each which are used by low to mid level smiths.

Iron smelting involves two main processes in the blast furnace. A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals generally pig iron but also others such as lead or copper. Blast refers to the combustion air being forced or supplied above atmospheric pressure.

1 the reduction of iron from it compounds and 2 its separation from its physical mixture with gangue materials.
