What are the differences between nickel pig iron and laterite nickel ore?
Laterite nickel oxide ore belongs to, at present, mainly from Indonesia, Philippines, is the main raw material of nickel pig iron smelting. According to the general domestic nickel iron alloy factory needs imports, mainly focus on the nickel content in more than 1.8% of the ore, also imports of nickel in the middle of 1.3--1.7, iron in 20---40, used for smelting nickel iron in taste there are domestic factory imports of nickel; in 1, 50 in iron ore, iron ore is mainly used to mix into reducing the cost. Ore is mainly used for smelting nickel pig iron (fire), also used for smelting nickel ore imports of ice (wet method).
Nickel pig iron smelting semi-finished products, are required by the steel plant, used for the production of stainless steel raw materials.Laterite nickel ore is a nickel oxide ore, which has no lower smelting grade and can produce nickel iron by using laterite nickel ore, and also can produce nickel metal by using laterite nickel ore.
According to the general iron nickel pig iron nickel content is different, can be divided into high grade nickel (10 and above) in nickel grade (4--9 months). Low grade nickel smelting nickel cast iron is mainly used in ore furnace and blast furnace smelting furnace, the general high grade nickel, low grade nickel iron blast furnace nickel. Pig iron is mainly for steel (Baosteel, Pohang) to use stainless steel smelting, such as 300 series, 200 series stainless steel.
