The liquid is between the gas and the solid. A lot of experimental data shows that it is closer to a solid, especially when it is near the melting point. Casting liquid metal into the cast, filled with the design of the cavity, it involves the flow of liquid metal in the mold, this process has a great impact on the quality of castings. The filling process can lead to various types of defects such as cold septa, underfill, inclusions, air holes, metal beans, sand inclusions, and sand defects. The process performance of liquid alloys refers to the properties required to meet a certain production process requirements. The process properties exhibited by liquid alloys in the casting production process are often referred to as casting properties. Castability is the ability to express high quality castings by alloy casting. . Casting performance is a very important process performance, has a significant impact on the quality of castings, casting process and casting structure. Casting performance has a great impact on the quality of castings, of which fluidity and shrinkage have the greatest impact, used to measure the quality of castings. Therefore, grasping the nature of liquid metal and filling capacity are conducive to determining a reasonable casting process parameters.
