Cast Iron Parts
Cast iron parts are metal products cast from molten iron. The material is mostly gray cast iron alloy with a carbon content of 2.5% to 4%. They are mainly used in handicrafts (such as ornaments, bells and tripods) and industrial fields (such as automotive parts, electrical hardware, valves). Its casting processes include sand casting, shell casting, die casting and centrifugal casting, etc. Among them, sand casting has become the mainstream due to its low cost and strong adaptability, while centrifugal casting can reduce porosity defects.
The quality of cast iron parts is divided into three dimensions: appearance, internal quality and service performance. Defects include pores, cracks, slag inclusions, etc. They are often repaired by argon arc welding or cold welding. Surface treatment can be carried out through an automated polishing process to remove oxide scale and burrs, enhancing brightness and rust resistance. The price is influenced by factors such as the complexity of the process, annual demand and transportation costs [1]. In 2012, among the regional output in China, Hebei Province had the highest proportion (19.18%), followed by Jiangsu and Henan. The output of Shanxi, Chongqing and other places showed a downward trend.
The quality of cast iron parts has a significant impact on the performance of mechanical products. For instance, the wear resistance and dimensional stability of machine tool castings directly affect the precision retention life of the machine tool. The accuracy of the dimensions, profiles and surface roughness of the impellers, casings and inner cavities of hydraulic components of various types of pumps directly affect the working efficiency, energy consumption and the development of cavitation of pumps and hydraulic systems. The strength and resistance to sudden cooling and heating of cast copper parts such as the cylinder block, cylinder head, cylinder liner, piston rings and exhaust pipe of internal combustion engines directly affect the working life of the engine.
