Features of gray iron casting
The basic characteristics of gray iron casting are: high clay content, low water content, low coal powder addition. Therefore, attention should be paid to sand preparation. In addition to the basic features of gray iron casting, today we will introduce the performance and heat treatment technology of gray iron casting.
Performance of gray iron casting
1. It has good casting and cutting machinability, and its smelting is convenient and the melting temperature is low.
2. Has good thermal conductivity, grey iron castings produced by internal combustion engine cylinder block, cylinder head, can rapidly around a lot of heat, good thermal conductivity is lower than at high temperature in the working of mechanical and electrical equipment is very important.
3. Good damping property, which can effectively absorb the energy of machine vibration and thus play a damping role, is also a very important performance of gray iron casting.
4. Flake graphite plays the role of cutting on the substrate, so that the gray iron casting as structural metal material is not sensitive to cutting.
5. Good lubrication performance, and good abrasion reduction performance when making sliding friction parts on mechanical and electrical equipment of gray iron casting.
