六 产品零件的试生产 经过试制,完成了三个模拟试块的解剖、加工、检查等工作,取得了无冒口铸造的经验。在此基础上,我们编制了产品零件轴承座工艺。 轴承座是汽轮机上的重要零件之一,它有前后之分。前后轴承座与前后汽缸联接,是安装汽轮机转子的床体,技术要求很高。几种典型零件工艺简介如下: 1.浇注系统:浇注系统的设计是无冒口铸造的关键。我们用阿暂公式计算阻流截 Trial production of six product parts After trial production, the three simulated test blocks were completed, such as anatomy, processing and inspection, and gained experience of no riser casting. On this basis, we have prepared the product parts bearing technology. The bearing seat is one of the important parts on the steam turbine, which has front and rear points. The front and rear housings are connected with the front and rear cylinders, which are used to install the steam turbine rotor bed. The technical requirements are high. Process description of several typical parts are as follows: 1. Gating system: pouring system design is the key to casting without risers. We use A temporary formula to calculate the flow blocking
