Casting historic application. Ancient people used to make castings and some life appliances. In modern times, mainly used for rough casting machine parts, precision castings, and some can also be used directly as machine parts. Casting mechanical products occupy a large proportion, such as tractors, the casting weight of about 50 to 70% by weight of the machine, agricultural machinery accounted for 40 to 70 percent, machine tools, internal combustion engines, such as the 70 to 90%. All kinds of castings, casting machinery used in the most varieties, the most complex shapes, the amount is also the largest, accounting for about 60% of total production of castings. Followed by the ingot mold and metallurgical engineering pipeline, as well as some of the tools of life. Casting is also closely related to daily life. For example, often use the door handles, locks, radiators, down the water pipes, pots, gas hob, iron and other ports towing tank, are casting. Casting quality has a great impact on the performance of mechanical products. For example, wear resistance and dimensional stability of the port slot machine casting streamers supply, directly affect the accuracy of the machine to maintain life; accuracy and surface of various types of pump impeller, housing and hydraulic cavity size, profile rough degree, directly affect the efficiency of the pump and the hydraulic system, the development of energy consumption and cavitation, and so on; the strength of the internal combustion engine block, cylinder head, cylinder, piston rings, exhaust pipes and other castings and resistance to spalling resistance, direct impact the working life of the engine.
