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 …

Hybrid method [edit | edit source]. It is possible to combine the smelting of gold ore with mithril, adamantite, or runite ore.This method takes advantage of the coal bag to create time-efficient trips for players who wish to reduce the cost of goldsmithing at the blast furnace without greatly reducing experience per hour, or for players wishing to add …

In the West, blast furnaces came into more common use in the Middle Ages - particularly once cast-iron cannons became a part of warfare. The invention of the steam engine allowed Britain to produce vast quantities of iron from its blast furnaces in the 18th century, which in turn allowed railways to spread across the British empire – …

The Blast furnace performs a similar function to the Smelter, although it can't smelt the ores that the Smelter can. The Blast furnace is used to process certain raw materials into Metal using Coal as fuel. Materials that can be smelted are: Black metal scrap Flametal ore The Blast furnace uses approximately 1 Coal every 15 seconds as fuel. It takes 30 …

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.

Now, ironworkers could achieve temperatures hot enough to blow way past the melting point of iron (1,538ºC / 2,800ºF). This meant that, instead of a solid reduced-iron bloom, liquid iron would run from the bottom of the blast furnace, which could be poured into casts, creating the first cast iron.

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.

A blast furnace is a steel cylinder lined with refractory. It operates continuously until the lining wears out, which takes many years to occur. The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400º to 2100ºF. Molten iron is produced in a blast furnace by the following steps: 1.
