对铸铁某些热分析数学模型精度及适用范围的分析

Analysis on the Accuracy and the Scope of Application of Mathematical Models of Thermal Analysis for Iron Melt

从液态铸铁的化学成分、冷却速度及添加的合金元素等对冷却曲线特征温度的影响出发，着重介绍了铸铁炉前热分析方法的理论基础及某些数学模型的适用范围。

In this paper, taking account of the effects of composition, cooling rate and alloying elements on the characteristic temperature of cooling curve for liquid cast iron, the theory of the thermoanalysis method for cast iron produced from cupola and its scope of application for some mathematical models have been presented emphatically.
