Why The Maximum Use Temperature Of The Heat-resistant Customized Casting Is Limited? How To Increase It Service Life?

Nov 30, 2017

The heat-resistant customized casting has good resistance to elevated temperatures, but the maximum use temperature will also be limited. There are many factors limiting this temperature.

First, the maximum use temperature has a great relationship with the chemical cost of the heat-resistant customized casting, which is shown in the influence of high temperature strength, oxidation resistance and corrosion resistance of the heat-resistant customized casting. This corresponds to a relatively direct impact on its maximum use temperature.

Another aspect is the effect of the heat-resistant customized casting size. When working in a high temperature environment, the casting will bear its own weight and deform. At the same time, the relationship between the size and oxidation rate should be considered. In addition to these, the working environment of the castings is also a major factor. In the same ambient medium substance, the temperature is not the same, it will have different results, and may also lead to damage to the surface of the casting.

If the heat-resistant customized casting wants to have a longer service life, it requires different types of equipment and accessories, and has a high temperature tempering before operation.

To ensure the service life of the heat-resistant customized casting, pay attention to ensuring the uniformity of the heat-resistant customized castings, and not accumulate the castings in a certain position, which will lead to uneven heat dissipation of the heat resistant castings during the heating process, resulting in deformation and cracking of the furnace plates. The choice of material should pay attention to preventing this kind of phenomenon, help to extend the service life of the work piece.http://www.pump-casting.com/
