AP1000核电常规岛焊接低压转子轴头的研制

R & D of Welded Low-pressure Rotor Head for AP1000 Nuclear Power Conventional Island

为攻克核电常规岛大锻件制造技术难题,通过对AP1000核电常规岛焊接低压转子的典型部件——电机端轴头进行分析,研究制定了该产品的冶炼、锻造和热处理工艺方案,并立项开展了1:1产品试验件的生产。在试制过程中,克服了制造难点,最终生产出符合规范要求的试验件产品。

In order to settle the technical problems involving the manufacturing of large forgings for conventional island of nuclear power, with the analyses of the shaft nose at the motor end- a typical component of welded LP rotor in conventional island of AP1000 nuclear power, a technological plan for smelting, forging and heat treatment was developed and formulated for the product with a project for 1：1 test piece production. In the trial process, the manufacturing difficulties were overcome and finally the produced test piece could meet with all specifications.
