克鲁索-罗华公司发展了一种制造蒸汽发生器封头的新方法。这种方法的特点主要是在于使用一个轧出或锻出的单件厚板圆盘,先行模锻成球面形状,然后用专用工具冲出接管。这样得出的产品就可以兼而具有先前两种工艺方法即整铸法(例如铸造封头)和锻造法(例如组合封头)的优点。它可以不用任何焊接。克鲁索公司的锻造厂为了发展这种工艺方法,曾制定和执行了一个重大的试验研究计划,其中包括了:-按照缩小的比例制造几个零件-和富兰马汤公司共同定出封头的最佳设计-按比例1:1进行冲孔试验-在试件上作非破坏性和破坏性检查。在取得十分令人满意的结果之后,克鲁索-罗华公司就用这种方法着手制造八个封头。其中有两个已经向富兰马汤公司交货。我们认为也可以利用这种方法来生产类似形状的零件。
Crusoe - Rover company has developed a new method of manufacturing steam generator head. The main feature of this method is the use of a single piece of rolled or forged heavy plate, forged into a spherical shape and then punched out with special tools. The product thus obtained combines the advantages of the two previous process methods, namely the casting method (for example, casting the head) and the forging method (for example, the sealing method). It can be used without any welding. Crusoe’s forging plant In order to develop this process, a major pilot research program has been developed and implemented that includes: - Several parts manufactured according to a reduced ratio - Co-settled with Flanomac Best head design - Punching test at a 1: 1 ratio - Non-destructive and destructive inspection on the test piece. With very satisfactory results, Crusoe-Rohua embarked on the process of creating eight closures. Two of these have already been delivered to Flanomac. We think this approach can also be used to produce similarly shaped parts.
