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% of the port towing tank supplies, machine tools, internal combustion engines, etc. up to 70 ~ 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, etc., are casting. Casting a variety of classification methods: by its use of different metal materials into steel, cast iron, bronze pieces, cast aluminum, cast magnesium parts, pieces of cast zinc, cast titanium parts. And each class can be divided according to their chemical composition or casting microstructure further divided into different categories. Such as cast iron can be divided into gray iron castings, ductile iron castings, vermicular cast iron, malleable iron, alloy cast iron pieces; according to different methods for molding, casting can be divided into ordinary sand casting, metal casting, die casting centrifugal casting, continuous casting parts, castings, ceramic castings, castings ESR, bi-metal castings. Among the most common application of sand casting, casting about 80% of the total production. The aluminum, magnesium, zinc and other nonferrous castings, mostly casting.
