The characteristic of stirring equipment is used a shaking sieve to disperse the adding pure fe or fe203 powder and used a combined stirrer instead of a common paddle stirrer to improve the shear effect to mixing melts . the particularity of fabricating process is the step of holding stirring at a constant high temperature . both of which can improve the even distributing degree of reinforcement phase in pure al matrix 搅拌设备的特殊之处在于使用了振荡筛分散加入粉末和更换组合式搅拌器来提高对混合熔体的剪切效果，工艺的特别之处在于一定温度下的保温搅拌过程，这二者均能提高强化相在纯al基体中的均匀分布。
Abstract : based on the developing trend and need of road construction in china , the technol ogy and study situation of asphalt mixing plant and paver , cement mixing plant an d paver , stabilized soil mixing plant and mixer are introduced , then according to the application of road construction and maintenance machinery at home and abro ad , the developing trend in china is presented in detail 文摘:从当前中国公路建设的发展动态和需求出发，首先分别介绍并分析了国内外沥青混凝土搅拌设备和沥青混凝土摊铺机，水泥混凝土搅拌设备和水泥混凝土摊铺机，稳定土厂拌设备和稳定土拌和机的技术状况和研究方向，随后就国内外公路养护机械的应用状况，具体提出了我国今后在路面施工机械和养护机械方面所发展的趋势。
Based on the analytical result of stirring kinetics , the maximal affecting factors to the size and distribution homogeneous degree of intermetallic al3fe reinforcement phase in al matrix during the stage of heat preservation stirring are studied , and some important parameters of stirring equipment and stirring process are ascertained , and the stirring processing is optimized 根据搅拌动力学分析的结果，研究了搅拌过程中对金属间化合物al _ 3fe强化相尺寸大小和分布均匀度的影响的因素，确定了搅拌设备和搅拌过程的几个重要参数，并对搅拌工艺进行了优化设计。
