摘　　要：为考察连续降温法在灰渣黏温特性测定中应用的可行性,用甘肃HT煤,研究了连续降温法与阶梯降温法测定结果的异同,以及不同降温速率对连续降温法测定结果的影响。结果表明,连续降温法和阶梯降温法测得的HT煤灰黏温特性在渣型上存在明显差异;且随着降温速率的增大,同一温度下连续降温法测得的黏度减小,黏温曲线整体呈向左移动的趋势,当降温速率大于5℃/min时,HT煤灰呈"玻璃体渣"特征。In order to investigate the application feasibility of continuous cooling method in slag viscosity measurment, Gansu coal HT was selected to study the measurement result difference between continuous cooling method and step cooling method, and influence of different cooling rate on the measurement result of continuous cooling method. The results showed that, there existed difference on slag type between the two cooling method, and with the increasing of cooling rate, the viscosity-temperature curve appeared the left moving trend,when cooling rate aboved 5 ℃/min ,slag HT presented＂ glassed slag＂.
