equipment production of iron from iron ore in finland
Production - voestalpine Stahl Donawitz GmbH
2022-2-6 · In nature, iron occurs as ore. In mining, the ore is extracted from the rock and processed. To make iron from the ore, it is reduced and melted in a blast furnace with coke at over 1300°C. The resulting pig iron contains more than 2% carbon and cannot be used for products in this form.

DRI production | International Iron Metallics Association
DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

Pig Iron Manufacturing Process - 911metallurgist
2017-3-20 · Pig Iron. In the electric-furnace production of pig steel from ore, carbon in the product can be kept below 2.2 per cent., and regulated to an extent by the amount of carbon charged, without resulting in excessive loss of iron in the slag or in the production of a pig steel very high in impurities, if a fair grade of ore is used.
