Embodiment
With reference to accompanying drawing structure of the present utility model and feature, details are as follows.
Water cooling device before the Valve Steel finish rolling of an embodiment of the present utility model shown in reference picture 1, Fig. 2 and Fig. 3
Structural representation, during the Water cooling device 20 is arranged between milling train 10 and pre- finish rolling milling train 30, it includes nozzle
Section 21, water cooling conduit 22, water exit end 25, return pipe 204 and the backwater casing 24 being connected with return pipe 204；Described nozzle
Section 21 includes one group of nozzle, and it is connected by conduit 211 with water inlet pipe 202, there is provided the cooling water source in water cooling conduit 22, it is described
Water inlet pipe 202 pick up a muddy water, Pneumatic diaphragm valve 205 is set on water inlet pipe 202, and thermometal detector (not shown) is arranged at
In the rear end of milling train 10, before infrared temperature detector 40 is arranged on finish rolling milling train (not shown), the Water cooling device 20
Both ends are connected with airway tube 201,203, and it is generally metal hose, are connected with sealing gland magnetic valve 271, and water shutoff is played by air pressure
Effect, prevent and treat cooling procedure in hot water overflow wear water installations；The Pneumatic diaphragm valve 205, thermometal detector, infrared temperature
Detector 40, sealing gland magnetic valve 271 are connected with digital display controller 50；The end of the backwater casing 24 is provided with air seal set 27.
The operation principle of Water cooling device of the present utility model is：When rolling milling train 10 during round steel goes out, by installed in
