粉末轧机

In this thesis , the fabrication technique of the high silicon - iron strips near to 6 . 5wt . % si by the direct powder rolling ( dpr ) technique were studied . the reaction mechanism between the iron and silicon powders was clarified
本论文详细的研究了利用粉末轧制法制备高硅铁硅合金带材(约含6 . 5wt .硅)的制备工艺过程，解释了铁硅粉在热处理过程中的反应机理，通过控制合理的加工制备参数，最终制备得到了高硅铁硅合金带材，并对其磁性能进行了表征。
Abstract : 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
文摘: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。
