Design of a Hydrogen Content on-line Measurement System in the Process of Steel Heat Treatment

Abstract

Abstract-This paper describes a hydrogen content on-line measurement system in the process of steel heat treatment based on the theory of hydrogen concentration cell. This System design includes two main measurement units and a MCU for calculation and output. The method of measurement data processing is discussed in this paper, and an algorithm of temperature value calibration is also proposed. Final test shows that the instrument has features of portability, continuity and real time capability, which make it has a potential future in the hydrogen content measurement in metallurgical enterprises.
