摘　　要：以丁烷加空气为流态化渗碳气源，系统试验研究了流态化渗碳温度、气氛碳势、刚玉粒径及表观流态化速度等对碳传递系数的影响。利用单纯形方法回归建立了不同条件下流态化渗碳碳传递系数数学模型和综合影响因素数学模型，试验验证表明，该数学模型具有较高的拟合精度。Systematic experiments have been made to study the effective factors to carbon transfer coefficient including carburizing temperature,atmosphere carbon potential,Al 2O 3 particle diameter and surfacial fluidizing velocity based on the carburizing gas resource of butane and air in a fluidized bed furnace.A series of mathematics model and a compound mathematics model under different fluidizing condition were deduced by use of Dan Chun Xing method.Experiment results showed that carbon transfer coefficient mathematics model deduced in this paper had a high precision.
