Learn About The Function Of Foundry-Grade Pig Iron

Pig iron is an essential element for the manufacturing of steel and grey iron casting. Despite the base material being the same, different types of pig iron specialize in different applications.

This is due to the different properties of the pig iron that make them different from one another. The basic grade pig iron is used particularly for the formation of steel making. But, the other type known as the foundry grade specializes in the manufacturing of grey iron castings.

What role does a foundry-grade pig iron play in the formation of grey iron castings?

There is a particular reason why the basic grade is not used for the formation of grey iron castings. Mostly this has to do with the properties of the pig iron. The work of foundry-grade pig iron in India is to remelt the castings into cast iron products.

Besides this, there are also other uses for this grade of pig iron. Let's take a look at it.

 Pig iron manufacturers use the foundry grade in the manufacturing of grey iron castings due to their high silicon content. This content is derived from raw material along with the addition of ferry-alloy additions.

 It also consists of elements like vanadium, lead, and titanium that are used to melt things that are of a high proportion of the lower grade. In return, it lowers the cost of scrap. Such changes in the physical and chemical composition of the grade allow it to be a prime component of the grey iron castings.

 Using foundry-grade pig iron in India supports the making of cast iron due to its melting ability and controlling the composition of the final casting. Besides this, it is also found to reduce the price of the heat treatment of casting which cost a lot.

 The pig iron manufacturers use this grade in cast iron which is used for making machines tools and parts and also in general engineering. The high amount of iron ore in the pig iron helps in the formation of the pearlite which supports the finishing of the castings.

 Another big advantage of using this grade is that it supports the formation of graphite formation which not only reduces primary chills but also improves the machinability of the thin-walled castings.

These were some of the vital reasons why foundry grade is in such high demand for the formation of grey iron castings.
