摘　　要：本文通过“带材尾端反推法”计算出粉末轧制工艺中粉末堆料高度对粉末轧制带材厚度、密度的影响， 并得出保证带材厚度、密度均匀的临界堆料高度； 同时指出了松装密度对临界堆料高度的影响。The effect of powder feed height on the thickness and density of powder rolled strip was calculated by using 'deduction from ends of strip”.The critical feed height ensuring uniform thickness and density of strip has been obtained.The effect of apparent density on the critical feed height is given as well.

关 键 词：粉末轧制 堆料高度 带材厚度 带材密度
