对热分析技术的特点进行了分析,提出了一种对铸造合金熔体成分及性能进行综合检测和预报的新的热分析技术.该技术可根据所测得的温度特征值及所回归的数学模型,预测灰铸铁和球铁的主要成分和性能.为了实现对所建数学模型的动态修正和更新,设计引用了对热分析模型自适应性分析软件模块.通过对冷却曲线形状的分析,实现对特征值的误判和预测值偏差的解释,将传统热分折技术从单纯的定量拓宽到了定量和定性相结合.在自动校正技术的基础上,设计开发了能对铸铁成分进行检测并预报其性能的微机热分析仪硬件电路系统和软件系统.

The characteristics of thermal analysis technology are analyzed, and a new thermal analysis technology for comprehensive detection and prediction of melt composition and properties of cast alloy is proposed. This technique can predict the main components and properties of gray cast iron and ductile iron according to the measured temperature characteristic values and the regressed mathematical model. In order to realize the dynamic correction and update of the built mathematical model, the design refers to the adaptive analysis software module of the thermal analysis model. Through the analysis of the shape of the cooling curve, the misjudgment of the eigenvalues and the interpretation of the deviation of the predicted values are realized, and the traditional thermal folding technique is broadened from simple quantification to a combination of quantitative and qualitative. Based on the automatic correction technology, a microcomputer thermal analyzer hardware circuit system and software system that can detect the cast iron composition and predict its performance are designed and developed.
