Carry out water-spraying control.
The cross section of the copper pipe of the quencher is in minor arc arc-shaped.
The axial centre of the water injector is equipped with the connecting hole being fixedly connected with quencher；The bottom end of the water injector
Around the annular watering trough of connecting hole setting on face；The water injector is equipped with the water inlet for being connected to annular watering trough inner top
Hole.
The inlet opening is arranged on the side wall of water injector.
The internal diameter and outer diameter of the annular watering trough of the water injector are gradually incremented by from the bottom to top.
The whole circular in cross-section of the quencher.
Using above-mentioned technical proposal, the utility model has below the utility model has the advantages that (1) the utility model uses copper pipe
It with magnetizer as quencher, solves faradic short-circuiting effect, workpiece can be greatly speeded up provided with water injector
