AI Technical Summary

Technical Problem

Existing equipment for measuring the temperature of molten metal pools is difficult to provide reliable temperature measurements over a wide range of applications, and it consumes a lot of cored wire and has poor response time.

Method used

The cored wire is constructed using a first metal tube with a yield strength of at least 140N and a filler layer material with a density of 0.3-1.1g/cm3. The filler layer material contains low-ash organic materials to control its decomposition behavior in the molten metal pool.

Benefits of technology

It improves the reliability and accuracy of temperature measurement, reduces the consumption of cored wire, shortens the response time, and is suitable for a wider range of applications.
