Surface temperature increasing : The temperature along with the casting direction and vertical casting direction gradient descent . The stress strain in side is significantly reduced. In addition, the application of air-blade has a great role in inhibiting crack.
Characteristics of Air-blade casting Billets：
1、Significantly refine the alloy micro-structure；
2、Inhibiting crack ;
the macro segregation of alloy element;
4、Purify the alloy micro-structure；
5、Improve the surface quality
