Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace …

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. It provides a great opportunity for players to reap great profits by producing a large volume of iron bars (worth 226 each), which are used by low-to-mid level smiths.

In blast furnace smelting, the silicon content in molten iron is an important indicator of the temperature trend of the blast furnace. Due to the multi scale, non-linear, large time delay and strong coupling characteristics of the blast furnace smelting process, the control effect of silicon content in hot metal is often not ideal.
