摘　　要：以某型高压加热器水室的球形封头制造工艺为例,针对封头压制过程中存在的难点问题,通过技术改进和创新研究,在满足相关标准要求的前提下,对压制封头时增厚在封头内外表面的余量,适当地进行了分配,降低了制造成本,提高了压制封头的技术水平和质量。Taking the manufacturing process of the spherical head in a certain type of high pressure heater water chamber as an example, for the difficult problems in the process of head forming, through technical improvement and innovation research, in the premise of satisfying the requirements of relevant standards, the margin of head inner and outer surface is thicken during the pressing to reduce the manufacturing cost and improve the technical level and quality of the Dressed head.
