Compressor is a general-purpose machine used to increase the pressure of various gases.
It is one of the large-scale and wide-ranging products in the machinery industry.
It has been widely used in many sectors of the national economy.
The cast iron parts in the compressor account for about 70%-80% of the total weight of the machine. With the needs of the country's modernization construction, compressors are developing in the direction of large-scale, high-pressure and serialization, which subsequently puts forward higher and more stringent requirements for iron castings in terms of technology, quality, reliability and economy.
The main cast iron parts of the compressor should have high strength, pressure resistance, wear resistance, heat resistance and other characteristics in casting, so the casting process requirements are very strict.
