solid billet

Pipe produced a solid billet that is heated and rotated under pressure.

由实心坯制成的管子,该实心坯在压力下加热和旋转.

With the enlargement of the columnar crystals ′ spacing interval, the positive and negative segregation extents generated by the periodic bending deformation at the liquid-solid interface of billet are enlarged.

固液界面发生周期性弯曲变形所引起的正偏析与负偏析的程度，随枝晶间距的增大而增加；

Therefore, the monitoring and control of the solid-phase volume fraction is a very important process in the thixotropic casting process, which has a direct impact on the shaping performance of semi-solid billet.

因此，固相体积分数的测控是半固态触变铸造过程中一个非常重要的环节，它直接影响着半固态坯料的成形性能。

The solid billet could also be used with a spider die, porthole die or bridge die.

固体钢坯也可用于模具的蜘蛛, 舷窗死亡或桥梁死亡.
