离心铸铝时,铝液在离心力和重力作用下注入转子槽中.铸铝模的浇帽分流口的尺寸及个数直接关系到铸铝的质量。若分流口偏小,则进入铁心槽的铝液流较细,易造成缩孔、断条等。若分流口过大,则铝液流截面较大,引起排空气困难,造成气孔,同时影响浇帽使用寿命。据在生产实践中探索,得出如何确定分流口尺寸及个数的一些方法,供参考。
Centrifugal cast aluminum, aluminum liquid in the centrifugal force and gravity into the rotor slot.Aluminum mold casting cap shunt size and the number of directly related to the quality of cast aluminum. If the diversion port is too small, then into the iron core slot aluminum flow thinner, easy to cause shrinkage, broken bars and so on. If the diversion mouth is too large, then the aluminum flow cross-section larger, causing the exhaust air difficulties, resulting in pores, while affecting the life of the cap. According to the production practice to explore, draw how to determine the size and number of diversion port for reference.
