摘　　要：根据传热学理论,在标准温升曲线条件下,以蛭石防火门为例,建立了防火门背火面温升简化预测模型。将防火门分为门扇和门框两部分,分别确定各部分的导热系数、热阻,通过对防火门背火面建立热平衡公式,建立温升预测模型。与实际测试结果的对比分析表明,预测模型结果误差较小。Based on heat transfer theory, and in the standard conditions of temperature curve, taking vermiculite fire door as an example, a temperature rise prediction model of fire door on the backs was built. The fire door was divided into door and doorframe, and the thermal conductivity and thermal resistance were decided separately. By heat balance equation on the backs of fire door, the temperature rise prediction model was built. It was shown by the contrast results between model and experi- ment that the error of the model is acceptable.
