Thermal parameters measurement and application of TA1 industrial pure titanium

  • 摘要: 为了实现纯钛板坯在钢铁工业加热炉中的加热过程自动化控制,测量了TA1工业纯钛在21.6 ~975 ℃的密度、比热、热扩散系数等参数,计算了导热系数,分析了这些参数的变化规律,得到纯钛的晶格结构转变温度约为885 ℃,并在此基础上开发了TA1钛坯加热自动控制模型,实现了在钢铁工业加热炉中高质量加热钛坯。工业试验结果表明,模型计算温度与钛坯出炉实测温度相差在9 ℃之内,表明该热物性参数及加热控制模型准确、可靠,满足工业化生产的要求。
