[0002] Pig iron casting is a metal processing technology that uses the plasticity of pig iron (an iron-carbon alloy with a high carbon content) to pour it into a pre-designed mold in a molten state, and then obtain a metal product of the desired shape and size after it cools and solidifies. During the casting process, the performance and quality of the casting can be affected by adjusting the chemical composition of the pig iron, controlling the casting temperature and time, and other factors.

[0003] The cooling methods commonly used in pig iron casting include natural cooling, water cooling and air cooling. Among them, water cooling is to put the cast casting into cold water to quickly cool it to room temperature.
