​What are the factors involved in temperature measurement in casting?

In the production of precision casting manufacturers, the process flow must be very clear. As an important parameter in the casting process, temperature control is particularly important. However, in the actual production process, it is difficult to measure the extremely high precision casting temperature. Even if the numerical value is not obtained, there is also a large error. What causes this? See how the foundry explains it?

In the process of precision casting manufacturers, the temperature of metal materials will have a great impact. Not only the external shape and size of the casting will change, but also the internal quality and performance of the product will be affected. It can be seen that temperature is important in the casting process. We must properly measure and control the temperature to ensure the quality and productivity of castings.

However, due to the influence of various factors, there will be a large error value in the casting temperature measurement. After analysis, it was found that the main reasons are as follows, maybe not all:

1. When metal materials are cast, various aspects change, such as composition, wavelength, temperature, etc.;

2. The gas generated during the precision casting process will act on the metal material, causing its thermal radiation to change;

3. Problems with the measuring instrument, such as its measurement signal becoming weaker;

4. The impact of pollutants, etc.
