the modeling design of gray cast iron parts. Irregular cross-section of casting parts (sudden thick and thin or sudden convexity of casting), too small inner rounded corners, and failure to set reinforcement bars will cause poor local design of gray cast iron parts, so that a little carelessness in handling will cause fracture of casting parts.

How to effectively avoid the fracture of gray cast iron parts?

1, the modeling design of gray cast iron parts. Irregular cross-section of casting parts (sudden thick and thin or sudden convexity of casting), too small inner rounded corners, and failure to set reinforcement bars will cause poor local design of gray cast iron parts, so that a little carelessness in handling will cause fracture of casting parts.

2、Design of pouring system. In the production process of gray cast iron parts, if the pouring system is poorly designed, it may cause the solidification speed of the casting parts to be difficult to reach the standard, which will lead to stress in the casting parts and produce deformation and fracture at the thin section of the casting parts.

3, the impact of casting materials. The metal composition of the gray cast iron parts is an important reason for the fracture of the casting parts. Certain metals are extremely sensitive to the cross-section and cooling rate, the use of such metals can easily cause the fracture of the casting parts.

4, other reasons. The main reason for the fracture of gray cast iron parts is still in the operation of the staff. Casting workers in the handling of gray cast iron parts from a high fall, in the cleaning work so that the castings collide with each other, casting parts in the pad tied too tightly, and other operational negligence, will accelerate the fracture of the casting parts.
