摘要
复合包套由金属套与隔热片组成，运用复合包套模锻可获得理想的锻造温度，降低变形抗力，细化晶粒；消除锻造裂纹，改善锻件性能，提高模具寿命。西南铝加工厂运用复合包套模锻新工艺首次在国内实现了大型难变形金属精密锻件的生产。
A new technology of die forming, with a metallic jacket intercalated heat insulating sheet to envelope the hot metallic work piece and keep its temperature to be decreased only a little, has been developed and used to produce large work pieces. The results showed that this technology could obtain ideal forging temperature, reduce forging loads, fine crystal grains, eliminate forging cracks, improve the properties of the forged work piece and lengthen the service life of the mould. For the first time, some large precise forged work pieces of unmanageable metals are produced in China.
