本文研究了粉末轧制镍多孔带材纵向性能的均匀性。在粉末轧制过程中,由于辊面粘粉,粉末与辊面间的摩擦系数、咬入角和轧制压力,以及带材厚度和密度都不断增加。为此,在轧制过程中采用一种擦辊设备,以不断清除粘附在辊面上的粉末和控制摩擦系数和咬人角的增加。这样,就获得纵向厚度和密度均匀的多孔带材。 In this paper, the uniformity of longitudinal properties of powder rolled nickel porous strip was studied. During the powder rolling process, the thickness and density of the strip are continuously increased due to the powder sticking on the roll surface, the friction coefficient between the powder and the roll surface, the bite-in angle and the rolling pressure. For this reason, a type of wiping device is employed in the rolling process to continuously remove the powder adhering to the roll surface and to control the increase of the coefficient of friction and bite angle. In this way, a porous strip of uniform longitudinal and density density is obtained.
