Internal quality, chemical composition, physical properties, mechanical properties, etc

Cast iron parts are collectively referred to as cast iron parts made from molten iron. Due to various factors, defects such as pores, pinholes, slag inclusions, cracks, and pits often occur.

Including appearance quality, intrinsic quality, and usage quality. Appearance quality refers to the surface roughness, surface defects, dimensional deviation, shape deviation, and weight deviation of castings; Mainly refers to the microstructure of castings, as well as the presence of pores, cracks, inclusions, segregation, and other conditions inside the castings; The quality of use refers to the long-term working ability of cast iron components under different conditions. Due to various factors, cast iron castings often exhibit defects such as pores, pinholes, slag inclusions, cracks, and pits. Common repair equipment includes argon arc welding machines, resistance welding machines, cold welding machines, etc. For casting defects with low quality and appearance requirements, welding machines with high heat generation and fast speed such as argon arc welding machines can be used to repair them.

The quality of cast iron parts has a significant impact on the performance of mechanical products. For example, the dimensional stability of machine tool castings directly affects the accuracy and lifespan of the machine tool; The size, accuracy of profile, and surface roughness of impellers, casings, and hydraulic components of various pumps directly affect the efficiency, energy consumption, and development of cavitation in pumps and hydraulic systems; The strength of cast copper components such as the cylinder block, cylinder head, cylinder liner, piston ring, and exhaust pipe of an internal combustion engine directly affects the working life of the engine.
