Specific embodiment
The embodiment of the present invention solves existing skill by providing a kind of detection method of precision rolling working roll cooling nozzles failure
Be difficult in art detection precision rolling working roll cooling nozzles whether the technical problem of normal work, can quickly judge that precision rolling working roll is cooled down
Nozzle whether normal work, it is ensured that finishing rolling step stabilization carry out.
Referring to Fig. 2, precision rolling working roll 1 is made up of upper precision rolling working roll and lower precision rolling working roll, and slab 6 is arranged on finish rolling
Between working roll and lower precision rolling working roll.The cooling nozzles of precision rolling working roll 1 include entrance top nozzle 2, entrance under nozzle 4, go out
Mouth top nozzle 3 and the lower nozzle 5 of outlet, cooling nozzles are used for cooling finish rolling working roll 1.
Referring to Fig. 1 and Fig. 2, a kind of detection method of precision rolling working roll cooling nozzles failure is the embodiment of the invention provides,
The method includes：
Step 10, the surface setting coating in precision rolling working roll 1, under the region and entrance top nozzle, entrance of coating covering
Nozzle, outlet top nozzle and the jeting area under outlet during nozzle normal work on precision rolling working roll surface are corresponded.Wherein,
Before the surface of precision rolling working roll 1 sets coating, the surface of precision rolling working roll 1 is decontaminated and dried process, ensure that painting
Adsorption effect between layer and precision rolling working roll 1.When the surface of precision rolling working roll 1 sets coating, control precision rolling working roll 1
Temperature be 0~50 DEG C, prevent the temperature of precision rolling working roll 1 it is too high cause coating solidify it is too fast.The thickness control of coating be 0.5~
1.5mm, coating uniform distribution, it is ensured that the marking on coating is high-visible.Wherein, nozzle 4, outlet under entrance top nozzle 2, entrance
Jeting area under top nozzle 3 and outlet during 5 normal work of nozzle on precision rolling working roll 1 determines according to multiple historical data.
Step 20, when coating surface air-dry and coating integrally be in soft condition when, precision rolling working roll 1 is assembled to finish rolling
In machine.Wherein, the shape invariance of coating is kept after the surface of coating air-dries, setting is served to coating.Keep coating be in integrally
The purpose that precision rolling working roll is assembled during soft condition is to ensure that cooling nozzles, in water spray, can impact formation print on coating
Note.
, to precision rolling working roll spray cooling water, cooling water impacts on coating and forms the marking for step 30, unlatching cooling nozzles.
In step 30, while opening the lower nozzle 5 of nozzle 4 under entrance top nozzle 2, entrance, outlet top nozzle 3 and outlet to precision rolling working roll
Water spray, the water of each nozzle is consistent with the water quantity holding of the corresponding nozzle in finishing stands during water spray, the time control of water spray
