33000kva nickel-iron furnace Various high temperature alloys,
iron-based and nickel-based alloys
Using the chemical reaction of nickel and iron at high
temperatures, nickel and iron ore are separated through a series of
smelting processes.
Nickel-iron smelting usually involves the following steps:
1. Ore pretreatment: the nickel iron ore is broken, and the ore is
pretreated to remove impurities and non-metallic components.
2. Ore reduction: The ore is reduced at high temperatures, usually
using coke or other reducing agents to reduce nickel and iron from
the ore. The chemical equation of the reaction can be expressed as
NiO + FeO + C → Ni + Fe + CO.
3. Smelting: The reduced nickel and iron and other additives (such
as limestone, coke, etc.) are put into a high-temperature furnace
for melting. In the smelting process, nickel and iron are gradually
separated to form nickel-iron alloys and iron slag.
4. Separation: by physical or chemical methods, the nickel-iron
alloy and iron slag are separated. Common separation methods
include magnetic separation, flotation, gravity separation and so
on.
5. Refining: The obtained nickel-iron alloy is refined to remove
impurities and impure substances and improve the purity of
nickel-iron alloy.
6. Metallurgical processing: the refined nickel-iron alloy is
processed into the required nickel-iron products.
In general, the principle of nickel-iron smelting is through the
reduction reaction and smelting process, the nickel and iron are
extracted from the ore, and separated into nickel-iron alloy and
iron slag, and then the nickel-iron alloy is refined and
metallurgical processing, to get the required product.
