本发明提供了一种超大规格高性能钨合金管及其制备方法。通过对混合原料组分及其配比、冷等静压成型条件、预烧结、旋转烧结、真空热处理的条件的优化改进和合理布局，开发出更适合超大规格钨合金薄璧件的工艺制备方法及工艺过程，通过二步烧结法和旋转烧结法，有效改善大型制件在烧结过程中易产生的收缩不均、损坏等问题。

The invention relates to a large-size high performance tungsten alloy tube and preparation method. By optimizing the alloy composition, improving the cold isostatic pressing, pre-sintering, rotary sintering and vacuum heat treatment processes, a preparation method which more suitable for ultra-large tungsten alloy thin parts are developed. Two-step sintering method and rotary sintering method are used to effectively improve the uneven shrinkage and damage of large parts during sintering.
