Technical field
The utility model belong to be installed in milling train or with the Workpiece surface treatment equipment technical field that rolling mill for metal is used in conjunction, relate to a kind of steel band descale liquid removing device.
Background technology
Cold-rolled strip be with hot rolled strip or or hot-rolled coil for raw material, carry out repeatedly rolling through milling train and form.There is the oxide skin formed during hot rolling on hot-rolled band surface, must remove before the rolling, otherwise can affect end product quality.Traditional descale technique is pickling, but pickling can waste a large amount of acid, and originally can the oxide skin of recycling cannot reclaim owing to being dissolved in acid, causes great waste, also pollutes the environment simultaneously.Removing acid mist, administering in the work of sewage, spend a large amount of manpower and materials again.
Therefore, the oxide skin on high-pressure water shot flow device removal steel band is used now.As shown in Figure 1, the removal steel band oxide skin equipment used now, comprising uncoiler 1, guide-in roller 2, outlet roller 8, winder 11, being arranged on distortion roller 6 and hydraulic cylinder 7 for supportting curved steel band after guide-in roller 2, the water jet device 5 be connected with water pump 4.The nozzle of water jet device points to steel band and the lateral surface being out of shape roller contact site.The below of whole equipment is provided with slag-draining device 13, and the water through deslagging enters water purification installation 9 and water tank 3.Between the nearest distortion rod of water jet device and downstream or outlet roller, be provided with air knife 12, air knife is connected with air pump 10, and air knife points to the lateral surface of steel band or distortion rod contact portion.
Air knife 12 is before steel band enters next distortion rod or outlet roller, and the liquid being mixed with the oxide skin under peeling off that may be out of shape on roller contact surface with second washes out, and prevents from being out of shape roller or outlet roller oxide skin pressure viscosity on steel band, causes secondary pollution.But the liquid on horizontally disposed steel band can not be removed very clean by air knife.
Utility model content
The utility model, in order to solve above-mentioned problems of the prior art, provides a kind of steel band descale liquid removing device be arranged between outlet roller and winder.
The utility model for addressing this problem taked technical scheme is:
A kind of steel band descale liquid removing device, is included in the first tilting roller, the first vertical roller, air jet system, the second vertical roller and the second tilting roller that set gradually between outlet roller and winder; Air jet system has the main body rack of symmetrical configuration, main body rack is formed with banded gas passage along axis, the bilateral symmetry ground of gas passage is formed with multiple air supply opening and fumarole, the openend of fumarole is communicated with gas passage, each fumarole is communicated with corresponding air supply opening, and air supply opening is connected with compressed air source by air feed pipe arrangement.
The equal opening in top and bottom of described gas passage, formation gas access, upper end, lower end forms gas liquid outlet.
The upper end of described main body rack is provided with connecting portion, main body rack be fixed on by connecting portion remove steel band oxide skin equipment housing or bracing frame on.
The advantage that the utility model has and good effect are:
Steel band descale liquid removing device of the present utility model, steel band is made to transfer vertical setting to by being horizontally disposed with, again by the gas passage in the middle of air jet system, the fumarole arranged from top to down sprays gas downwards, liquid on steel band is gone out from lower end, thus before steel band rolling, removes the liquid that steel band retains completely.

Detailed description of the invention
Referring to the drawings and specific embodiments, steel band descale liquid removing device of the present utility model is described in detail.Specific embodiment described below is only preferred forms of the present utility model, and can not be interpreted as restriction of the present utility model.
Fig. 1 is the structural representation of existing removal steel band oxide skin equipment; Also be the equipment of the removal steel band oxide skin that liquid removing device of the present utility model is applied, as shown in Figure 1, remove steel band oxide skin equipment, comprise uncoiler 1, guide-in roller 2, outlet roller 8, winder 11, be arranged on distortion roller 6 and hydraulic cylinder 7 for supportting curved steel band after guide-in roller 2, the water jet device 5 be connected with water pump 4.The nozzle of water jet device 5 points to steel band and the lateral surface being out of shape roller contact site.The below of whole equipment is provided with slag-draining device 13, and the water through deslagging enters water purification installation 9 and water tank 3.Between the nearest distortion rod of water jet device and downstream or outlet roller, be provided with air knife 12, air knife is connected with air pump 10, and air knife points to the lateral surface of steel band or distortion rod contact portion.
During work, steel band is when guide-in roller 2, the oxide skin of surface attachment can there occurs bending, oxide skin and steel band have had certain being separated, and define two kinds of gaps, be called the first gap and the second gap, the first gap is the gap of opening towards steel band direction of advance, and the second gap is that opening is towards the gap contrary with steel band direction of advance.When the first gap runs to the upstream end of distortion roller, the opening in the first gap is just towards nozzle, and because nozzle is motion, the first gap can be chipped by the High-Pressure Water of its ejection, and oxide skin is come off.In like manner, when the second gap runs to the output of distortion roller, the second gap also can be washed open by current, and oxide skin comes off, thus realizes operating the scale removal of one side steel band.Steel band, again after outlet roller 8, exports winder 11 to.
Fig. 2 is the structural representation of steel band descale liquid removing device of the present utility model.As shown in Figure 2, steel band descale liquid removing device of the present utility model, is arranged between outlet roller 8 and winder 11, is disposed with the vertical roller 16 of the first tilting roller 15, first, the vertical roller 18 of air jet system 17, second and the second tilting roller 19.
Fig. 3 is the sectional side elevation of air jet system of the present utility model.As shown in Figure 3, air jet system 17 has the main body rack 24 of symmetrical configuration, main body rack 24 is formed with banded gas passage 21 along axis, the bilateral symmetry ground of gas passage 21 is formed with multiple air supply opening 23 and fumarole 22, the openend of fumarole 22 is communicated with gas passage 21, each fumarole 22 is communicated with corresponding air supply opening 23, and air supply opening 23 is connected with compressed air source by air feed pipe arrangement.The upper end of main body rack 24 is provided with connecting portion 14, main body rack 24 be fixed on by connecting portion 14 remove steel band oxide skin equipment housing or bracing frame on.
The equal opening in top and bottom of gas passage 21, make to form negative pressure in gas passage because fumarole 22 sprays gas downwards, therefore the opening of its upper end is gas access, and the opening of lower end is gas liquid outlet.
Steel band 20, through the first tilting roller 15 and the first vertical roller 16, transfers vertical placement to by horizontal positioned, then through the gas passage 21 of the main body rack central authorities of air jet system.Now, the fumarole 22 of steel band 20 both sides is aimed at steel strip surface and is oliquely downward sprayed gas, is gone out by the gas liquid outlet of the liquid that steel band retains from lower end, can remove the liquid that steel band retains completely.Then steel band goes back to horizontal positioned through the second vertical roller 17 and the second tilting roller 15 by vertically placing again.
