陶瓷制品在辊道窑的烧成过程的温度变化直接影响到出窑的产品质量。本文建立了陶瓷制品烧成过程的流体动力学和传热特性的理论模型，基于CFD商用软件Fluent的动网格技术进行了数值求解，得到了陶瓷制品烧成过程的动态热响应特性。研究表明：陶瓷制品在烧成带加热的初期，温度在不断升高，制品前部温度变化快于制品后部的温度变化。随着时间的推移，制品本身的温度差别越来越小。燃烧器喷出烟气的速度越大，制品被加热的速度越快，制品受热引起的温度不均匀性越小。

The temperature variation of ceramic firing process in roller hearth kiln has an important influence on product quality. The theoretical model is developed for predicting the lfuid dynamics and heat transfer characteristics of ceramic ifring process in the roller kiln, the software to be called Fluent of CFD is used to solve the control equations numerically based on dynamic mesh technique, dynamic thermal response of ceramic ware is obtained in the process of ifring. It is indicated that temperature of ceramic ware rises gradually in the initial heating period of ifring zone, the front temperature of ceramic ware is faster than the rear temperature. Temperature difference of ceramic ware becomes smaller and smaller as time goes by. The temperature of ceramic ware shows more quick variation with an increase of the velocity of lfue gas that is sprayed from the burner, temperature nonuniformity during heating is unconspicuous.
