Cast iron flat casting overview
What is the casting of cast iron plates? A cast iron plate is a casting made from metal smelting. Specifically, the red hot gray iron liquid is poured into a casting formed by solidification in a model made of sand.
Flat casting is a special process for metal processing. Most castings are gross and need to be machined to become a qualified cast iron plate. Some castings can be applied directly as finished products or parts when they meet the size and surface roughness requirements. Therefore, the quality of flat castings is the basis for further processing.
Cast iron plates are cast because they can produce complex shapes, especially for parts with complex internal cavities, box-type cast iron plates, cast iron square boxes, etc.
Casting production has wide adaptability and great process flexibility. Metal materials commonly used in the industry can be used for casting, and the weight of the casting can range from a few kilograms to several hundred tons.
Disadvantages of flat casting: Loose casting structure, coarse grain, easy to produce shrinkage, shrinkage, porosity and other defects inside, therefore, the mechanical properties of cast iron flat castings, especially the impact toughness is lower than the forgings of the same material.
The quality of cast flat castings is not stable enough.
