What Are The Factors Of Temperature Measurement in Casting?

In production, it is necessary to be very clear about the process flow of precision casting parts, and as an important parameter in the casting process, the control of temperature is particularly important. However, in the actual production process, it is difficult to measure the very precise casting temperature, and the value is obtained, which also has a large error. What causes this? See how the foundry explains it?

In the process, the temperature of the metal material 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 the temperature is the main character in the casting process, and we must properly measure and control the temperature to ensure the quality and productivity of the casting.

However, due to the influence of various factors, the casting temperature measurement will have a large error value, after analysis found that the main reasons are the following points, perhaps not all:

1, metal materials in the casting, all aspects have changed, such as composition, wavelength, temperature, etc.;

2, the gas generated in the process of precision casting will act on the metal material, making its thermal radiation change;

3, the problem of the measuring instrument, such as its measurement signal becomes weak;

4, the impact of pollutants and so on.
