1978年,一种被称作欧诺(Ohno)连续铸造法(以下简称OCC法)的新工艺问世了.这种方法的优点是,生产出的铸料无杂质的宏观偏析、无气孔和无晶界. 由这种铸造法生产的任何金属和合金,都可成为性能高、质量好的新材料,即OCC法能生产出先进的工业材料(简称AIM). OCC法适用于纯镁线材或板材的水平铸造.由这种方法生产的铸料几乎全是单向凝固组织.铸料具有极好的加工性能(如轧 A new process known as Ohno Continuous Casting (OCC) was introduced in 1978. The advantage of this method is that the produced castings have no macro-segregation, no porosity and no inclusions Grain boundary .All metals and alloys produced by this casting method can become new materials of high performance and good quality, that is, OCC method can produce advanced industrial materials (AIM for short) .The OCC method is suitable for pure magnesium wire or Horizontal casting of plates The castings produced by this method are almost all unidirectional solidified castings with excellent processability
