                                  真空热处理技术是近些年发展起来的一种新型的热处理技术,它所具备的特点

                                   低压铸造   的优点表现在以下几个方面: 
                                  1.液体金属充型比较平稳; 
                                  2.铸件成形性好,有利于形成轮廓清晰、表面光洁的铸件,对于大型薄壁铸件的成形   为有利; 
                                  3.铸件组织致密,机械性能高; 
                                  4.提高了金属液的工艺收得率,一般情况下不需要冒口,使金属液的收得率大大提高,收得率一般可达90%。 
                                  此外,劳动条件好;设备简单,易实现机械化和自动化,也是低压铸造的突出优点。
