摘要
研究了双锥混合器的混合时间、填充率、转速对W+C混合粉的碳量均匀程度和碳化钨粉的总碳、游离碳的影响。结果表明双锥混合器生产效率高、碳化钨粘结度低、化合碳也高,完全可以替代用球磨机配碳的传统工艺。制备好的W+C炉料必须选择合适的充填系数、转速和混合时间。
In this article , the influence of the the bipyramid blender mixing time ,the charge ratio,rotaing speed on the uniformity is studied of the mix of coarse W＋C and total carbon/free carbon of tungsten carbide .The result shows that the mix of W＋C prepared by the the bipyramid blender has high chemical carbon.less the Fe content . the bond strength of WC block is small and the proudtion efficiency is high.h can take over the conventional ball-blending process at all.To produce good mixture,it must apply apposite mixing time, rotaing speed or charge ratio.
