The relationship between precision casting and intermediate frequency induction furnace is as follows:
If induction furnace is the main equipment of foundry workshop, the stability, reliability and safety of the work are the guarantee of the normal and stable work of the casting production line. At present, induction smelting furnace has been developed rapidly, and gradually replaced cupola.
In addition to melting in the atmosphere, induction furnaces can be melted in the atmosphere of vacuum and argon Shan helium to meet the special quality of the precision casting? requirements. In addition to the smelting principle, the following characteristics are also compared with other smelting furnaces:
(1) using electromagnetic induction to direct the material heating, high thermal efficiency.
(2) Due to the lack of use of air in the smelting, the elements burn less what AH impurity mixing also less to some precision foundry factory
(3) Simple operation, composition adjustment, adding trace elements and temperature control is easy, precision casting.
(4) is the melting furnace around or sent to the precision casting factory? Heat emitting less, soot occurrence is low what AH work environment improvement, is conducive to environmental protection is good, is fine casting
(5) Small footprint.
(6) High current density professional production of precision casting parts suitable for high temperature smelting yes, precision foundry
(7) Easy to realize automatic control, in particular, can be controlled by computer.
(8) If the magnetic field to the melting precision casting function? The metal has the magnetic stirring action, is advantageous to the constituent uniformity and the dross, the liquid metal composition and the temperature are all more homogeneous.
Top A: The high quality of the lost wax precision casting
Silica Sol Casting Special Fast dry silica Sol is mainly aimed at the precision casting into shell slow, production cycle of long, late Qing shell difficult shortcomings developed a product, the product without changing the casting process parameters, can shorten the shell time to the original 1 3 1 4. It can increase the strength of room temperature and reduce the residual strength, so that the difficult problem of the shell in the late casting is effectively solved. It is suitable for castings with strict requirements of strength and surface finish.
The precision casting of lost wax method is superior to that of ordinary precision casting:
Lost wax precision Casting is now called precision precision casting, is a small cutting or no cutting precision casting process, is a precision casting industry in a good technology, its application is very extensive. It is not only applicable to various types, the precision casting of all kinds of alloy, and the casting dimension precision, the surface quality is higher than other precision casting methods, and even other precision casting methods are difficult to cast, the complex, high temperature, not easy to process castings, can be used precision precision casting casting.
1) A wide range of adaptation. Casting method is almost not limited by the size of castings, thickness and complexity of the shape, the most suitable for the production of complex shapes, especially the complex internal cavity parts, such as complex box, valve body, impeller, engine cylinder body, propeller and so on.
2 The casting method can be used in a wide range of materials, almost anyone can be melted into liquid alloy materials can be used for casting. such as cast steel, cast iron fly all kinds of aluminum alloy, copper alloy, continuous alloy, ferroalloy and alloy bowl castings.
3 Casting has a certain size accuracy. In general, it is more accurate than ordinary forgings and welding parts.
4 low cost, good comprehensive economic performance, energy, material consumption and cost for other metal forming methods.
