摘要
在工业生产条件下测量了连续铸管铸铁结晶器中间环面的温度分布。温度分布有两个峰值,第一个位于液面附近,温度最高,是由于凝固收缩造成;第二个与铸铁石墨化膨胀有关。分析了结晶器的热流,建立了二维稳定态效学模型。根据测量结果和二维稳定态反同题方法计算了结晶器的温度场和热流,并提出了改善结晶器寿命和连续铸管生产的措施。
Temperature distribution of the middle annular face of the mould in continuous casting pipe processing has been measured in industrial production condition. The temperature distribution has two peaks. The first peak is due to solidification shrinkage, and the second peak is related to the graphitizing expansion during solidification of cast iron pipe. Mould heat flow has been analyzed. A 2-dimensional steady state mathematical model has been developed for mould thermal behavior. Based on the measured temperature and by using a 2-dimensional steady state inverse problem method, temperature field and heat flow of mould have been calculated. According to the measured and calculated results, the means for improving service life of mould and production of continuous casting iron pipe has been suggested.
