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。
Butane and air were used as the fluidized carburizing gas source. The influences of fluidized carburizing temperature, carbon potential, corundum particle size and apparent fluidization velocity on the carbon transfer coefficient were systematically studied. The mathematical model of the fluidized carburizing carbon transfer coefficient and the mathematical model of the comprehensive influencing factors under different conditions were established by using the simplex method regression. The experimental verification shows that the mathematical model has high fitting accuracy.
