轧辊双频淬火机用斜喷淬火环的研制与应用

RESEARCH ON THE QUENCHING RING USED IN DOUBLE FREQUENCY QUENCHING MACHINE

在轧辊双频淬火机上 ,设计了淬火环轴向和圆周方向均成一定角度的新型斜喷淬火环代替原来的平喷淬火环 ,不仅使轧辊的淬火环裂率得到有效控制 ,而且轧辊的有效淬硬层从 1 2mm提高到 1 5mm ,经济效益十分显著。

The plain spray ring used in double frequency roll was replaced by a new quenching ring with the spray holes deflected a certain angle to its axial and circumference orientation.The effective hardened layer on the roll was raised from 12 mm to 15 mm,and the circular crack rate was controlled also,the economical benefit was excellent.
