Further be that the purging water ejiction opening that purges (operating) water nozzle is the flat fan structure.
Further be to purge purging water that the water transfer pipeline carries and be pressure and be the water source commonly used on the hot-rolling line of 0.3 ~ 1.2MPa.
Further be, also comprise along roll mandrel to the flipper guide cover plate that is provided with at least one spray orifice and blow device collector at least one flipper guide cover plate that purges (operating) water nozzle is installed, the purging water input of blow device collector is communicated with the output that purges the water transfer pipeline on the flipper guide cover plate, purging (operating) water nozzle on the flipper guide cover plate on the blow device collector is positioned at the spray orifice on the flipper guide cover plate, and the output axis of described purging (operating) water nozzle is 40 °~60 ° angle with the moving direction that is rolled product.
Further be on the purging water input of purging water transfer pipeline solenoid electric valve to be installed.
Further be on the purging water transfer pipeline of solenoid electric valve output, flow control valve to be installed also.
The beneficial effects of the utility model are: the surperficial blow device that adopts structure described in the utility model, owing to being installed to milling train, blow device collector on the water beam that a plurality of purging (operating) water nozzles will be installed defends on the plate, and adopt water as the blowing medium of this surface blow device, like this, just effectively eliminate and purge noise, need in advance air to be compressed as blowing medium unlike the employing air before purging, thereby effectively reduce the purging cost, splashing in the purge flows away with purging water, avoided the generation of secondary sputtered phenomenon.Simultaneously, blow device collector on the water beam of surperficial blow device is installed to milling train defends on the plate, simplified the mounting structure of blow device, be convenient to safeguard, operate very simple, the convenience that all becomes.
Description of drawings
Fig. 1 is the structural representation of the utility model hot-rolled product surface blow device;
Fig. 2 is the A-A cutaway view of Fig. 1.
Be labeled as among the figure: blow device collector 2, purging water transfer pipeline 3, spray orifice 4, milling train are defended plate 5, are rolled product 6, are purged blow device collector 9, solenoid electric valve 10, flow control valve 11 on water ejiction opening 7, flipper guide cover plate 8, the flipper guide cover plate on purging (operating) water nozzle 1, the water beam.
The specific embodiment
Be that a kind of purging noise of providing of the utility model is little, cost is low as shown in Figure 1 and Figure 2, can not produce the two hot-rolled products surface blow devices that splash in the purge.Described surperficial blow device comprises blow device collector 2 on the water beam that a plurality of purging (operating) water nozzles 1 are installed, purge water transfer pipeline 3 and defend plate 5 along roll mandrel to the milling train that is provided with a plurality of spray orifices 4, being arranged on milling train, to defend the quantity of the purging (operating) water nozzle 1 of installing on the blow device collector 2 on the quantity of the spray orifice 4 on the plate 5 and the water beam suitable, the input of blow device collector 2 is communicated with on the output that purges water transfer pipeline 3 and the water beam, purging (operating) water nozzle 1 on the water beam on the blow device collector 2 is positioned at the spray orifice 4 that milling train is defended plate 5, and the ejection axis of described purging (operating) water nozzle 1 is 40 °~60 ° angle with the moving direction that is rolled product 6.Adopt the surperficial blow device of described structure, owing to being installed to milling train, blow device collector 2 on the water beam that a plurality of purging (operating) water nozzles 1 will be installed defends on the plate 5, and adopt water as the blowing medium of this surface blow device, like this, just effectively eliminated the purging noise, no longer need in advance air to be compressed as blowing medium as the employing air before the purging, thereby effectively reduce the purging cost.Be 40 °~60 ° angle owing to purge the ejection axis of (operating) water nozzle 1 with the moving direction that is rolled product 6, like this, splashing in the purge just can effectively flow away with purging water, can not enter roller gap, avoided the generation of secondary sputtered phenomenon.Simultaneously, blow device collector 2 on the water beam of surperficial blow device is installed to milling train defends on the plate 5, simplified the mounting structure of blow device, make maintenance, operation all become very simple, convenient.Simultaneously, adopt water as blowing medium, can also avoid " foreign matter " to produce " sintering " at high temperature, under at a high speed and be attached to and rolled on product or the rolling mill guiding device, further improve and purge effect.
In the above-mentioned embodiment, in order to make the whole width that when spraying, just can cover the product that is purged as the purging water of blowing medium, can reduce to greatest extent again simultaneously purging (operating) water nozzle 1 along the layout quantity that is rolled product 6 widths, the purging water ejiction opening 7 that purges (operating) water nozzle 1 is the flat fan structure.Like this, it is much bigger just can be than the purging (operating) water nozzle that adopts circular configuration the time that each purges the purging width of the purging water of (operating) water nozzle 1 ejection, both guaranteed to purge water and when ejection, can cover the whole width that is rolled product 6, and can reduce to greatest extent again purging (operating) water nozzle 1 along the layout quantity that is rolled product 6 widths simultaneously..In order to improve the purging effect, but increase that can be not excessive purges cost, purges purging water that water transfer pipeline 3 carries and be pressure and be the water source commonly used on the hot-rolling line of 0.3 ~ 1.2MPa; On the purging water input of purging water transfer pipeline 3 solenoid electric valve 10 is installed; On the purging water transfer pipeline 3 of solenoid electric valve 10 outputs, flow control valve 11 is installed also.Simultaneously, purging the water transfer pipeline 3 described solenoid electric valve 10 of installation and flow control valves 11, can also play head time-delay control and the adjustable effect of flow, thereby the problems such as " noses " of effective controlled rolling crossing process guarantees rolling and steady quality.
For fear of the dead angle occurring purging, in conjunction with also having the design feature of flipper guide cover plate 8 on the milling train, surperficial blow device of the present utility model also comprises along roll mandrel to the flipper guide cover plate 8 that is provided with at least one spray orifice 4 and blow device collector 9 at least one flipper guide cover plate that purges (operating) water nozzle 1 is installed, the purging water input of blow device collector 9 is communicated with the output that purges water transfer pipeline 3 on the flipper guide cover plate, purging (operating) water nozzle 1 on the flipper guide cover plate on the blow device collector 9 is positioned at the spray orifice 4 on the flipper guide cover plate 8, and the output axis of described purging (operating) water nozzle 1 is 40 °~60 ° angle with the moving direction that is rolled product 6.
