Pig iron powder

Pig iron powder means that the pig iron is ground into a powder, while pig iron is a ferroalloy with a carbon content of more than 2%.
The pig iron powder is obtained by reducing iron oxide at high temperature under hydrogen gas. The reducing power is particularly strong and the properties are very lively. It is often referred to as "Flintstone". Ordinary iron powder is a single iron powder.

As the pig iron powder is a very active iron powder, because of its strong reducibility, it is prone to oxidation reaction, even burning in the air will burn slightly, because of its characteristics, it is often used to weld rails, Chemical reduction, prevention of oxidative deterioration, etc.
