Development of a Thermal-analyser for Measuring Al-Si Alloy Modification Effect

This paper introduces the design of hardware and software of a thermal-analysis meter for measuring Al-Si alloy modification effect, and discusses its application. The main hardware includes a sample cup, a compensate case for cooling end, an isolated amplification circuit for thermocouple signal and a gathering data card. The software was compiled into blocks by using language C. It is shown from application results that it has very good capacity in anti-jamming and is reliable in judging the modification effect, so can be used for monitoring the modification treatment in production.
