Nickel pig iron (NPI) is a low grade ferronickel invented in China as a cheaper alternative to pure nickel for the production of stainless steel [citation needed]. The production process of nickel pig iron utilizes lateritic nickel ores instead of pure nickel sold on the world market.

2010年11月17日 · Growth in nickel pig iron output, which can be cheaper to produce than traditional nickel metal, is undermining primary nickel prices and threatens to tip the global nickel market into...

Nickel pig iron is smelted mainly in submerged arc furnaces and blast furnaces. Generally, submerged arc furnaces produce high-grade nickel pig iron, and blast furnaces produce low-grade nickel pig iron. Nickel pig iron is an important source of nickel raw material for stainless steel.

Nickel pig iron (NPI) production is a new promising process, although it was firstly developed about 50 years ago but it has not been commercially used until some Chinese pig iron producers changed their production methods into NPI production.

2024年6月11日 · The Indonesian government is conducting a comprehensive evaluation regarding the termination of permits for the RKEF smelters which make products in the form of ferronickel and nickel pig iron, a...

2013年4月1日 · Nickel (Ni) pig iron is a ferro-nickel pig iron containing 3 % to 13 % of Ni. It is a low grade ferro-nickel invented in China as a cheaper alternative to pure Ni for the production of stainless steel.

This is the nickel pig iron (NPI) with 2.5–5.5% Ni that comes from laterite smelting in the blast furnace (B/F). Eventually, the advantages of the R/K-E/F process led to its dispersion in China and Indonesia and resulted in an NPI production with 3–12% Ni.

Nickel pig iron containing chrome and nickel is used for stainless steel production. The use of NPI gives the possibility of reducing consumption of FeNi and FeCr in the process of stainless steel production.

2024年2月8日 · It is expected that the national nickel pig iron production in February 2024 will be around 26100 nickel tons, with a month on month decrease of 8.13% in metal production compared to January. According to SMM research, it is currently approaching the Spring Festival period, and some companies are in the shutdown stage.

More recently, the nickel sector has seen structural change driven by the emergence and consolidation of nickel pig iron (NPI) production, first in China, then in Indonesia, followed by the establishment of stainless steel (SS) production facilities in Indonesia to take advantage of …
