根据回转窑内物料颗粒的运动特点,推导了颗粒团在贴壁运动过程中的非稳态导热系数及界面处的接触传热系数,进而得出了物料与封盖窑壁间的换热系数;结合已有研究成果,建立了回转窑的传热数学模型。计算表明,未考虑物料与窑壁间歇接触对回转窑传热过程的强化效应时,物料温度偏低;温度越高,强化效应对物料温度的影响越大;考虑物料与窑壁间歇接触对回转窑传热过程的强化效应,有利于提高回转窑煅烧熟料的质量和热效率。

The energy consumption of crushing is directly affected by the mechanical properties of cement materials. This research provides a theoretical proof for the mechanism of the stress relaxation of cement clinkers under high temperature. Compression stress relaxation under various high temperatures is discussed using a specially developed load cell, which can measure stress and displacement under high temperatures inside an autoclave. The cell shows that stress relaxation dramatically increases and that the remaining stress rapidly decreases with an increase in temperature. Mechanical experiments are conducted under various temperatures during the cooling process to study the changes in the grinding resistance of the cement clinker with temperature. The effects of high temperature on the load-displacement curve, compressive strength, and elastic modulus of cement clinkers are systematically studied. Results show that the hardening phenomenon of the clinker becomes apparent with a decrease in temperature and that post-peak behaviors manifest characteristics of the transformation from plasticity to brittleness. The elastic modulus and compressive strength of cement clinkers increase with a decrease in temperature. The elastic modulus increases greatly when the temperature is lower than 1000 °C. The compressive strength of clinkers increases by 73.4% when the temperature drops from 1100 to 800 °C.
