Description
Technical field
The utility model relates to the pickle line processor equipment before a kind of straightener, is applicable to steel plate, belt surface processing.
Background technology
On present domestic cut deal and the hot rolling line, the slab overwhelming majority is directly to enter straightener, and surface of steel plate can influence leveling effect and plate surface quality so often with iron scale (being commonly called as " squama ") at this moment, smoothing roll easy to wear influences service life simultaneously.The slab or the steel plate that enter straightener often have the nose situation, also can influence nipping and the leveling effect of head of straightener, and increase the straightener burden.
Therefore set up pickle line processor before the straightener, remove iron scale, improve leveling effect and plate surface quality.Usually de-scaling all is specifically to be implemented by last lower collector pipe and the hydraulic spray thereof established in the De-scaling box, and the scale removal effect quality directly has influence on product quality.For better satisfying market demand, nearly all hot rolled steel plate enterprise all can use the blank of several different section thickness to organize production.Because the slab lower surface carries the fixedly roller-way top roll face of slab to contact all the time with in the De-scaling box, distance between therefore following descaling header and nozzle and slab lower surface remains unchanged, but last descaling header and nozzle can often change along with the different of slab thickness with the spacing of slab upper surface.
At present, what the descaling mill that has adopted is that motor or fluid motor-driven elevator structure are controlled the upper header lifting, and the employing that has is that Driven by Hydraulic Cylinder connecting rod or swing arm drive upper header realization lifting.Electrodynamic type is because the often influence of lifting and de-scaling water vapour corrosion, and some descaling mill just uses after a period of time can't lifting.The hydraulic up-down structure that has adopts locks the different lifting travels that hydraulic cylinder locks upper header, but frequent appearance locking centering is ineffective or failure causes fault; The hydraulic up-down structure that has adopts the Driven by Hydraulic Cylinder swing arm to drive upper header and realizes different lifting travels, but the nozzle spray angle that is installed on upper header is changing along with different lifting travels, thereby scale removal effect is affected, this structure only can be applied to except the dissepimentarium varied in thickness is little, lifting travel is little descaling mill, as hot continuous rolling etc.; The hydraulic up-down structure that has adopt the hydraulic-driven connecting rod drive upper header and top nozzle, along with the circular swing motion of connecting rod realizes different lifting travels, though the de-scaling of top nozzle height and de-scaling angle remain unchanged, scale removal effect are not impacted, but the spray site position, front and back of top nozzle changes, this need propose the particular design requirement to front and back surrounding devices structure, simultaneously this structure also is limited to the de-scaling lifting travel and changes little descaling mill, as hot continuous rolling etc.
At present, be to adopt chain to block de-scaling water before and after the descaling mill, the limitation of blocking because of chain, there are a large amount of de-scaling water to spill from descaling mill often.Carry out de-scaling if there is the strip of nose to enter descaling mill, the de-scaling that causes because of nose highly changes, causes scale removal effect to be affected.
The utility model content
The purpose of this utility model is to provide a kind of pickle line processor that can carry out the slab head of warpage before straight peen, the adjustable for height straightener of upper header.
To achieve these goals, by the following technical solutions: the pickle line processor before a kind of straightener, comprise descaling header and pinch roll, it is characterized in that: described pinch upper roll departs from rolling direction up and down nip rolls, form arranged off-centre, inlet guard and flange stripper guide are contained on the backplate crossbeam, the backplate crossbeam is contained on the pinch upper roll bearing block, last descaling header is contained on the flange stripper guide, the hydraulic cylinder vertical-lift of band displacement transducer is adopted in the lifting of last descaling header and top pinch roll, and descaling header is all the time with the pinch upper roll vertical lift in the realization.
Top pinch roll adopts motor or fluid motor-driven, between top pinch roll roller and motor, clutch is set, be provided with the cooling water of open and close controlling at top pinch roll, when pinch roll began to pinch, throw-out-of clutch drove, the top pinch roll cooling water control is closed, this moment top pinch roll to become idler roller servo-actuated with pinching, bide one's time when pinch roll finishes to pinch and is in to wait, clutch on-off drives the top pinch roll rotation, the top pinch roll cooling water control is opened, and top pinch roll opens to aperture position.
Described pickle line processor outlet arranges adjustable for height jet collector.
The utility model can carry out straight peen to the slab head of warpage; The upper header adjustable height, it is convenient that simple in structure, installation is controlled, even if under the situation of different slab thicknesses, still with the jetting height of the best and optimum angle injection de-scaling, therefore bring into play its optimum hitting power, thereby guarantee to reach best scale removal effect to the different-thickness slab; Clutch separation when pinch upper roll pinches, it is idler roller, clutch engages when crossing steel, its rotation of driven by motor; Jet nozzle is used in outlet instead, can seal the water under high pressure and the iron scale that splash, and steel slab surface is residual moisture not also, and adjustable height, is suitable for the slab of different-thickness.
1, before straightener, slab is carried out de-scaling, prevent that iron scale is pressed into slab in the aligning process, can improve plate surface quality, protect smoothing roll simultaneously, prolong smoothing roll service life, improve leveling effect.
2, pinch under roll arranged off-centre on the entrance pinch roll, pinch upper roll is offset a segment distance to rolling direction, slab is fulcrum with the pinch under roll, when pinch upper roll is depressed, can realize slab warpage head is carried out the function of straight peen, reduce the nose of de-scaling steel plate, can improve scale removal effect, and reduce straightener and sting to enter risk, reduce the straightener burden.
3, going up descaling header is installed on the pinch upper roll backplate, backplate links to each other with the pinch upper roll bearing block, and collector, backplate, nip rolls assemble integrated, and upper header is all the time with vertical " stepless " lifting of pinch upper roll, guarantee de-scaling strike height and hitting power well, thereby guaranteed scale removal effect.The pinch upper roll backplate is namely protected pinch upper roll, also prevents that as the collector water fender water under high pressure from splashing simultaneously, protection upper header nozzle.
4, pinch upper roll increases a motor or hydraulic motor, and motor or hydraulic motor link to each other with pinch upper roll by clutch, when needs pinch mode of operation, and clutch separation, this moment, pinch upper roll was idler roller; When having served as steel, pinch upper roll rises to highest point, and clutch is in engagement state; motor or hydraulic motor drive pinch upper roll and rotate, and can guarantee that the body of roll is heated evenly, and the cool water shower cooling evenly; thereby protect nip rolls better, keep optimum Working, increase the service life.
5, entrance water shutoff: when entrance pinch roll pinches slab, stoped water to overflow descaling mill, played the effect of water shutoff.
6, outlet water shutoff: descaling mill outlet arranges adjustable for height jet collector, to stop water and the iron scale that falls after rise that splashes overflows the descaling mill outlet, reaches better scale removal effect.Because the slab thickness change frequency is not high, can adopt artificial hoisting way, or by the leading screw up-down mode.
