摘要

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。

Abstract: To control the heating process of industrial pure titanium slab (TA1) automatically, the parameters such as density, specific heat capacity, thermal diffusivity and thermal conductivity in the range of 21.6～975 ℃ were measured or calculated. The variation trends of the parameters were analyzed, and the phase-transition temperature of the pure titanium was determined at 885 ℃. Based on the obtained experimental results, an automatic combustion control (ACC) model of the heating process of the TA1 slab was developed. Industrial applications show that the difference in the average tapping temperature of the TA1 slab is within 9 ℃ between the calculated temperature by the developed model and the measured temperature. It indicates that the thermal parameters and the ACC model are accurate and reliable, meeting the industrial production requirements.
