印尼公主港3×350MW电厂由3个机组组成,主厂房钢结构全部采用高强螺栓连接,高强螺栓数量达50万套,因此制作精度要求较高。为了保证构件的制作精度,在制作前对作业人员进行认真详细的技术交底,在制作过程中对构件的几何尺寸进行严格控制,对制孔等关键工序采用数控钻孔、套模钻孔等先进制孔工艺。并对构件进行整体预拼装,检验制孔的精度;在作业过程中严格执行制作工艺流程,控制每一道工序的制作质量,层层把关,严格执行自检、互检和专检制度。经过以上控制措施,构件整体预拼装质量满足设计要求,效果良好。
Indonesia’s Puerto Princesa 3 × 350MW power plant consists of three units, all the main plant steel structure using high-strength bolts, high-strength bolts up to 500,000 units, so the production of high precision. In order to ensure the accuracy of component production, the operators should be carefully and technically submitted before the production. The geometrical dimensions of the components should be strictly controlled in the production process. CNC drilling, Hole making process. And the overall pre-assembled components to test the accuracy of the hole; in the process of strict implementation of the production process, control the quality of production of each process, check at all levels, strictly enforce the self-test, mutual inspection and special inspection system. After the above control measures, the quality of preassembled components as a whole to meet the design requirements, the effect is good.
