The invention relates to a device and method for preventing thin galvanized sheet from sticking to the roll. upper and lower guide plates. The device can make the galvanized sheet pass through the front guide plate to reach the work roll smoothly, and use the air jet assembly to spray the galvanized sheet to form an air cushion between the galvanized sheet and the work roll, which can effectively prevent the galvanized sheet from adhering to the work roll , In particular, it can avoid sticking rolls of thin galvanized sheets with a thickness of 0.7mm or less.
Description
Technical field
The present invention relates to a kind of devices and methods therefor that prevents zinc-plated roll banding.
Background technology
Zinc-plated unit is to coil of strip continuous zinc coating the time; At first utilize Abrollhaspel that coil of strip is carried out uncoiling, with shears the coil of strip head and tail is sheared then, shear back coil of strip head and weld through welding machine with a last coil of strip tail again; Thereby the assurance whole production line is moved continuously; After cleaning section, get into galvanizing furnace annealing again, send it in the zinc pot, form iron-zinc alloy on the surface.Yet; After surface of steel plate forms iron-zinc alloy, again behind equipment such as polishing machine and stretching straightener, steel plate shearing; Coil into the finished product volume by reeling machine again through roller platform, outlet turning, clamping and conveying roller; Wherein, the effect of outlet turning, clamping and conveying roller is when wearing steel plate or get rid of the steel plate tail, to clamp steel plate, and walking is led to steel plate.
Outlet turning, clamping and conveying roller of the prior art comprises working roll and the pressure roller that is arranged on this working roll top; And be installed in deflector roll before the working roll forward; And at the working roll rear portion upper guide plate and bottom guide are installed, wherein working roll and pressure roller roll surface all are lining urethane material.Because the outlet turning, clamping and conveying roller after clamping steel plate, can make steel plate produce slight deformation, urethane can produce certain viscosity under certain environment simultaneously; So, when the process of the steel plate galvanized below 0.7mm outlet turning, clamping and conveying roller, " gluing " roller phenomenon very easily takes place; Be that steel plate galvanized sticks to roll surface and do not separate; Cause the steel plate head can not smoothly transit on the bottom guide, the steel plate head can not get into the reel jaw smoothly, thereby the steel-fastening fault takes place.Because zinc-plated unit is a tinuous production, if the long disorderly closedown in any one position can both cause the shutdown of whole piece unit, the generation of steel-fastening fault can directly cause the shutdown of whole unit; Simultaneously, because the lehre of this unit is in the non-oxidation burner hearth, to be designed to burner flame directly burn, the phenomenon that causes steel plate to be blown extremely easily after the shutdown, thus cause the fault extension; In addition, zinc-plated unit is after parking, when beginning the production of cycling start again; Because steel billet temperature is lower in the lehre, the band steel does not also reach annealing temperature in the follow-up entering stove, causes the steel sheet zinc coating that soaks at the zinc pot to thicken; Its surface has formed cadmia, rolled tin; Such steel plate is at the deflector roll of the surperficial line with rubber of process, when rectifying a deviation roller, tensioning roller, and the cadmia rolled tin can embed in the roller line with rubber layer, and pair of rollers has than macrolesion.
Summary of the invention
Task of the present invention provides the device that prevents the galvanized sheet roll banding that a kind of mode of utilizing blowing gas solves galvanized sheet roll banding problem.
Another task of the present invention provides a kind of method that prevents the galvanized sheet roll banding.
The device that prevents flash plating zine plate roll banding proposed by the invention comprise be installed in the working roll front portion by the front guide of stent support be installed in the jet assembly of this front guide bottom, and the upper guide plate and the bottom guide that are installed in the working roll rear portion.Said jet assembly comprises spray beam, and the gas inlet pipe of band reversing valve is installed at the two ends of this spray beam, and this spray beam is provided with the jet hole towards the working roll upper end.
Said front guide is mounted obliquely within on the support from the steel plate direction of travel.The upper end of said bottom guide is provided with towards the crooked bend of working roll direction.
Utilize said apparatus to prevent the method for galvanized sheet roll banding, may further comprise the steps:, start the top jet gas of jet assembly, so that form air cushion between the last end face of steel plate and working roll to working roll when the thickness of steel plate during less than 0.7mm.
The device that prevents the galvanized sheet roll banding proposed by the invention adopts front guide to substitute existing preceding deflector roll, makes galvanized sheet arrive working roll through front guide reposefully, phenomenons such as vibration and end sinking can not occur, also helps simultaneously jet assembly is installed; Jet assembly just is made up of spray beam and the gas inlet pipe that has reversing valve; Utilize this jet assembly winding-up galvanized sheet simple in structure; Make between galvanized sheet and the working roll and form air cushion; Can avoid galvanized sheet to stick on the working roll effectively, particularly can avoid thickness is the flash plating zine plate roll banding below the 0.7mm.This device can enlarge the production range of zinc-plated unit, reduces the number of times of zinc-plated unit disorderly closedown, thereby can reduce rejection number, enhances productivity.
Description of drawings:
Accompanying drawing 1 is the surface structure synoptic diagram of an embodiment of the device that prevents the galvanized sheet roll banding proposed by the invention;
Accompanying drawing 3 is enlarged views of spray beam in the accompanying drawing 2.
Embodiment:
Referring to Fig. 1, this figure provides the surface structure synoptic diagram of an embodiment of the device that prevents the galvanized sheet roll banding proposed by the invention.This device comprises and is installed in working roll 4 forward supports 1 and the front guide 2 that is installed in support 1 upper top, and jet assembly 3, upper guide plate 5 and bottom guide 6 at the roller rear portion of working roll 4.For steel plate 7 can successfully be got in the reel jaw (not providing among the figure) of crimping machine 8; Be provided with towards the crooked bend 61 of working roll direction in the upper end of bottom guide 6; This bend 61 can make the upper end of bottom guide 6 near working roll 4, thereby makes steel plate 7 get into crimping machine through bottom guide 6.
Referring to Fig. 2 and Fig. 3, these two accompanying drawings provide the surface structure synoptic diagram of 3 one embodiment of jet assembly.Jet assembly 3 comprises the spray beam of being processed by steel pipe 31; Be separately installed with a gas inlet pipe 32 at the two ends of this spray beam 31; And reversing valve 33 and throttling valve 34 are installed on each root gas inlet pipe 32, and wherein, reversing valve 33 can adopt the bi-bit bi-pass reversing valve; Because bi-bit bi-pass reversing valve 33 all belongs to prior art with throttling valve 34, so do not provide concrete structure among the figure.Spray beam 31 is provided with a row or two row's jet holes 35 in the direction towards working roll 4 upper ends, and the diameter of spray beam 31 both sides jet holes 35 is greater than the diameter of middle part jet hole 35.
Zinc-plated unit is when giving steel plate zinc-plated; At first confirm the thickness of steel plate; If the thickness of steel plate less than 0.7mm, is opened two bi-bit bi-pass reversing valves 33 and throttling valve 34, by the top jet gas of the jet hole on the spray beam 31 35 towards working roll 4; So that form air cushion between the last end face of steel plate and working roll 4, can prevent the galvanized sheet roll banding effectively.
