AusIron process

AusIron furnace is designed to produce about 500,000 t/a of hot metal when smelting typical iron concentrates and to generate about 100 MW electric power, of which onethird is consumed by the smelter. The hot metal capacity of the same AusIron furnace can be tripled when smelting hot prereduced iron concentrate.

Smelting Iron the Viking Way

Apr 07, 2016 · They are dug 40 – 50 cm into the ground. One of the challenges is of course to get the 1200 – 1300 o celcius, needed to smelt the iron from the bog ore. This is done by continually feeding the oven from the top with charcoal. This implies a process whereby any Vikings would need to first burn a cartload of charcoal, which takes about five days.

This smelting process melts out and separates iron from the original rock material. Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and carbon dioxide (CO 2). This iron is often known as "pig iron" or "hot metal" as it is a liquid ...

Smelting is the process in which one transforms ore (or Dwemer metal scraps) into ingots. Although related to Smithing, smelting does not improve the Smithing Skill. Smelters can be found in most large towns, as well as near many mine entrances. There are six different materials that can be smelted into Dwarven metal ingots, but looting all of them from Dwemer Ruins will .
