What role does pig iron play in Dongguan casting?

Pig iron is also commonly known as gray iron. Dongguan cast iron has good performance due to its soft and slippery graphite, good cutting performance, and good wear resistance. However, its tensile strength is not enough and cannot be forged, so it can only be used to make various castings, such as Dongguan casts various machine tool bases, iron pipes, etc.

The quality control of Dongguan casting pig iron often stays at the level of chemical composition, which is the basic raw material of Dongguan casting.

Dongguan is a large-scale mechanized foundry production enterprise. With the continuous progress of my country's machinery manufacturing industry, the quality requirements for pig iron are getting higher and higher. We not only require the chemical composition of the pig iron to be suitable, but also require the appearance quality, slag amount and density.

Part of the cast iron in Dongguan is produced by small blast furnaces. At the same time, there are many factors that affect the quality of pig iron, because there is no unified standard for the cast iron machines used in production, and there is no standardized system in the use process.
