Research and Design of Multifunctional Intelligent Melted Iron Analyzer

A multifunctional intelligent melted iron analyzer is researched and designed. This device combined the function of thermal analysis for quality analysis of melted iron and ultrasonic measuring for nodularity. By thermal analysis, equation of linear regression wasused and the percentage composition of carbon, silicon and phosphorus etc. were obtained. In addition, thermal analysis was used to predict gray iron inoculation result, structure and performance. Therefore, ultrasonic measuring was adopted to be applied in this study to survey the nodularity of spheroidal graphite iron. In order to protect the analyzer far away from boiling melted iron, wireless temperature collection was adopted. The system is composed of PC104, single chip SPCE061 and other peripheral circuits. Designed temperature collection and ultrasonic measuring module, the software of data analysis and management is programmed by VB6.0 based on PC104 and windows operation system. After running for more than one year, the analyzer goes very well in the foundry.
