1. Adapt to a wide range. Casting is almost free from the cast size, thickness and shape of the complexity of the restrictions, throwing a wall with a thickness of up to 0.3 ~ 1000mm, length from several millimeters to 10 meters, the quality from a few grams to more than 300t. Most suitable for production of complex shape, especially the inner cavity of complex elements, such as a complex field, valve, cylinder rotor, propeller.
2. Casting material can be widely used in almost any material can be blended into the molten alloy can be used for casting. Such as steel, cast iron fly all types of aluminum alloys, copper, added aluminum, aluminum alloy castings of iron and the bowl. For less brittle plastic alloy, casting in the forming process is possible only in the industrial production of commonly used cast iron, cast by more than 70% of the total production.
3. Does a certain size precision castings. Under normal circumstances, than conventional forging, welding, forming part of the exact size.
4. Low costs, the economy, energy, material consumption and costs less than other metal forming methods.
Casting Used to the total weight of the total 40% to 80%, while manufacturing costs represent only 25% of the total cost of the device to 30% 0 low cost, because:
1. The production is flexible, mechanized mass production can be organized.
2. Is it worth it to use the old metal waste and renewable resources.
3. Compared with the forging of its small power consumption.
4. The precision of a certain size, so that allowance, shorten processing time and metal. Casting machines industry is rough and the main suppliers of parts, in the national economy is an extremely important place. Casting in the mechanical industry, the proportion of large goods, such as internal combustion engines are a key part of the casting that 70% to 90%, the casting quality of the vehicles represent 19% to 23%, machinery, tractors, hydraulic pumps, valves and overall quality of the casting machines 65% to 80% of agricultural machinery castings. The quality accounted for 40% to 70% of mining and metallurgy, energy, aerospace and marine heavy, large equipment difficult in both accounts for a large part of the cast and play an important role.
casting, also known as the "lost wax casting, usually in several layers of wax and coated with the material, let it dry and harden, the wax melts, that the tank, then after baking, it pours, obtained by casting, because casting obtained high accuracy and surface, the so-called "Casting". casting method can produce the type of alloy carbon steel, alloy steel, heat-resistant alloys, stainless steel, aluminum accurate, permanent magnet alloy, bearing alloys, copper alloys, aluminum, titanium and iron, and so forth.
Castings are generally more complicated shapes, castings may be expelled from the smallest hole diameter of 0.5 mm, minimum wall thickness of 0.3 mm casting. In the production of some of the original can be combined with more components, by changing parts of the structure, intended to direct the general part cast out of the casting, to reduce processing time and consumption of metallic materials, so that the structure is more reasonable.
Castings are mostly zero scores of cattle weight, heavy castings casting method of production is a little trickier, but the production of casting weight cattle were around 800 people.
Casting process, it is simply made of refractory materials in an easily melted Ke Xing model at the top a number of special coatings Ceng De refractory paint after drying and curing Zheng Xing Cheng a Ti Kehou type, and then steam or hot water from the melting model of a shell and then placed in a shell sand pit, filled with dry sand in the molding around it, and finally thrown into the smoking-room high-temperature baking, shape or coating after baking, then pouring the molten metal to be cast.
High dimensional accuracy of castings, usually up to CT4 ~ 6, of course, as the process of casting process complex factors that influence the size of the precision casting for more materials, such as shrinkage, melting and deformation mode of the coating in an amount cooling the heat in the process of changing the line alloy solidification shrinkage and deformation during the casting process, so the size of the usual precision castings are higher, but we still need to improve their consistency.
Suppression of cell surface melting mode, complete the type of high pressure, therefore, melting of the surface of the mold is relatively high. In addition, special coatings and adhesives high temperature refractory coating made of the fireproof coating scales in their wallets and made contact directly with the molten metal surface finishing high bay. As a result, investment castings castings ranging in size from an average height, usually Ra.1.6 ~ 3.2μm.
Casting of the biggest advantages is that because the castings have a high dimensional accuracy and the smoothness of the surface, it can reduce machining, only in part by requiring the allowance may be a little longer, and even the cast just stay grinding, polishing margin, can be used without treatment. This shows that the use of the casting method can save a lot of equipment, machine tools and processing time, substantial savings of metal materials.
Another method of casting of the advantages is that it can throw a lot of complex alloy castings, in particular, can be made at a high temperature alloy castings. Such as engine blades jet, slim profile and cooling outside the cavity, the treatment process almost impossible. In the production of the casting process can be done not only to mass production, ensure consistency of the casting and machining in order to avoid the knife on the pattern of other concentrations.
