摘　　要：对自制的设备进行控制系统的改装,使得轧制参数便于调整。进行水雾化铁粉轧制试验,确定了随机轧制时带材相对密度和粉末松装相对密度及厚度的关系,分析了初始辊缝大小和摩擦系数对带材性能的影响。试验表明,对于150mm轧辊,当初始辊缝为0.475mm时,可轧制出最厚为1.22mm带材。The existing equipment＇s control systems were refitted in order to conveniently adjust rolling parameters. Water-atomized iron powder rolling experiments were carried out,whereby strip density relating to apparent density and thickness of powder was established,furthermore ,the effect of roll-seam size and friction coefficient on strip performance was analyzed. Experiments results indicate that there exists an optimum initial roll-seam size of 0.475mm to obtain maximum strip thickness of 1.22mm under rolling wheel size of 150mm.
