Above side, the quantity of protective cover 4 described in the present embodiment is one, and above the feed side of the circular hole 341.High pressure water
It is sprayed by the nozzle 340, inclination sprays to the steel material 1, and oxide skin is shot down and rushes at 1 supplied materials direction of the steel material, together
When protective cover 4 is set in this direction, avoid the oxide skin splashing range of fragmentation, peeling larger, be convenient for oxide skin clast receipts
Collection, while 4 installation space of protective cover can be saved；The water spraying direction of nozzle 340 described in the present embodiment is moved with the steel material 1
The angle in direction is 45 degree, verified, and in the angle, fragmentation, the oxide skin splashing range of peeling are smaller, and to oxide skin
Elimination effect is preferable.
Embodiment 9
A kind of hot rolling fetus device of the present embodiment, basic structure is any with embodiment 2,4,5,7 and 8, different and improvement
Place is that the high-pressure injection time of the nozzle 340 is t=L/V, and wherein L is the length of steel material 1, and V is the speed of steel material 1,
That is the time of spraying water with high pressure of the nozzle 340 sets different spray water with high pressure the time according to the difference of L and V.V is conveyed with carrying roller
The setting transmission speed of device 2 is consistent, generally 1~2m/s, is 1.5m/s in the present embodiment, when 1 length of steel material is 1.5m, institute
The time of spraying water with high pressure for stating nozzle 340 is set as 1s, and according to verifying repeatedly, the effect that descales at this time is best.The present embodiment
A kind of hot rolling fetus device is reasonably sprayed water with high pressure the time using setting, on the one hand can drop low water usage cost, on the other hand subtract
Lack 33 energy consumption of booster pump, reduces electric cost.
Embodiment 10
A kind of hot rolling fetus device of the present embodiment, basic structure is any with embodiment 2,4,5,7 to 9, the nozzle 340
High-pressure injection pressure be 160~180MPa.It is verified, when the irrigation pressure of the nozzle 340 is less than 160MPa, steel material 1
Although the oxide skin on surface can be washed out, there can be residual, it can not be cleared；When the irrigation pressure of the nozzle 340 is more than
When 180MPa, since surge is larger, fragmentation, the oxide skin splashing range of peeling are larger, are unfavorable for oxide skin clast concentration
Recycling.The irrigation pressure of nozzle 340 described in the present embodiment is 170MPa, through verifying repeatedly, when the hydraulic pressure, is descaled and oxygen
It is best to change skin clast splashing range comprehensive assessment.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in also be the utility model one of embodiment, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
