1、64000DWT舵叶制作工艺一、舵叶装配（Theassembleofrudder）1、胎架制作(Fabricationofrudder)舵叶采用以侧板为胎架进行卧造，按图纸及样板尺寸制作胎架，并安装模板。胎架支柱必须与预埋件进行钢性连接，胎架必须标明FR0号肋位对合线和船体中心线，分段脱胎前必须将各种对合线移至舵叶上并清晰地打上洋冲。Usethesideplateofrudderasjig,thejigshouldbeassembledasthedrawingsandexample.Pillarsofthejigmustbec

4、on)因舵叶的顶面大而底面小，所以水平隔板的腹板与面板的交角不相垂直，同样垂直隔板的面板和腹板的交角也不相垂直，为了保证水平隔板和垂直隔板的面板连接光顺，不出现局部的凸起或凹陷，故在进行T型隔板装焊时，需进行预拼装，待水平和垂直隔板的面板调整光顺后，装其拆分开来，将面板和腹板进行临时加强后焊接。Forthetopandthebottomplateoftherudderarenotinthesamesize,theangleofthefaceandthewebofthehorizontalpartitionplateisnotv
