本发明提供一种大长径比钼坩埚旋压用钼板的轧制方法，首先根据所需钼板坯尺寸选取合适的模具进行装粉，然后将装粉的模具进行压型制得板坯，再将压型后的板坯进行烧结，通过交叉轧制的方法对烧结后的板坯进行大变形量的轧制，使其内部组织之间的结合力提高，通过交叉轧制可以得到各向同性的细小纤维组织，且纵横向组织相互交错搭接，组织更为均匀，能有效的避免各向受力不均匀时产生的缺陷，为后续旋压提供有利的条件，本发明采用冷等静压、烧结和大变形量的交叉轧制方法对钼原料板坯进行加工，使其满足大长径比钼坩埚的旋压要求，对大长径比钼坩埚的生产具有重要的意义。

The present invention provides a rolling method of molybdenum plate for molybdenum crucible spinning with large aspect ratio. Firstly, a suitable mold is selected for powder filling according to the required size of molybdenum slab, and then the powdered mold is pressed to obtain a slab. , And then the pressed slab is sintered, and the sintered slab is rolled with a large amount of deformation through the cross-rolling method, so that the bonding force between the internal structures is improved, and the cross-rolling can obtain each The fine fibrous tissue of the same sex, and the vertical and horizontal tissues are interlaced with each other, the tissue is more uniform, which can effectively avoid the defects generated when the force is uneven in all directions, and provide favorable conditions for the subsequent spinning. The present invention adopts cold etc. The method of static pressing, sintering and large deformation cross rolling process the molybdenum raw material slab to meet the spinning requirements of molybdenum crucible with large aspect ratio, which is of great significance to the production of molybdenum crucible with large aspect ratio.
