Abstract
The utility model relates to a kind of gauge length device for dotting of on-line proving finishing elongation percentage, the device is located between the slewing rollers before the horizontal top roller of continuous annealing line unit and polishing machine entrance, including bracket, idler wheel, handle, pedestal, frame bottom and pedestal are movably hinged, cradle top is connected with idler wheel, handle is fixed on idler wheel center, and the idler wheel is equipped with calibration salient point.Advantage is: overall structure is simple, is easy to manufacture, easy to use, improves the accuracy of continuity unit (hot galvanizing line, continuous annealing line) polishing machine elongation percentage calibration, while reducing because of shutdown loss caused by demarcating polishing machine.Between slewing rollers before the present apparatus to be located to the horizontal top roller of continuous annealing line unit and polishing machine entrance, it can be ensured that idler wheel is close on the steel plate, the calibration of a stroke be carried out using calibration salient point using handle by the accuracy of detection, simple to operate.
Description
Technical field
The utility model relates to a kind of gauge length device for dotting of on-line proving finishing elongation percentage.
Background technique
Galvanizing unit polishing machine is on-line continuous equipment, compared with cold rolling line single stand skin pass mill machine, using static demarcating
Mode demarcate elongation percentage detected value and can not obtain exact value；Galvanizing unit polishing machine elongation percentage calibration difficult point, that is, polishing machine be
Non- single devices connect zinc pot and Lu Qu before, behind connect straightening and passivation section, the gauge length L before finishing1It static can not beat
Point and measurement, the practical elongation percentage of finishing is chronically at the state that can not demarcate verification, can only be subject to the real value of on-line checking,
Cause due to the online elongation percentage detection inaccuracy of finishing, roll-force control deviation influences final products performance, performance is caused not conform to
Change the original sentence to degradation product.
In order to guarantee the accuracy for measuring and detecting, it is necessary to assure the strip of calibration is annealed condition, unit speed
Must be identical or close as normal process speed, while in order to avoid the stretching of strip in zinc pot and furnace area is to gauge length L1Shadow
It rings, gauge length L1Get ready and must be carried out in the inlet close to polishing machine in non-shutdown or reduction of speed in the state of.The above is difficult
Point determines the calibration of galvanizing unit polishing machine elongation percentage, can not use the scaling method of cold rolling producing line single stand skin pass mill machine, palpus
It makes and dedicated gets gauge length L ready online1Tool.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a kind of marks of on-line proving finishing elongation percentage
Away from device for dotting, meet the requirement of polishing machine on-line proving elongation percentage, caused by accuracy is demarcated in raising, while reduction is because of calibration
Shutdown loss.
To achieve the above object, the utility model is achieved through the following technical solutions:
A kind of gauge length device for dotting of on-line proving finishing elongation percentage, the device are located at the horizontal top roller of continuous annealing line unit and light
Between slewing rollers before complete machine entrance, including bracket, idler wheel, handle, pedestal, frame bottom and pedestal are movably hinged, top of support
Portion is connected with idler wheel, and handle is fixed on idler wheel center, and the idler wheel is equipped with calibration salient point.
The pedestal is bolted between the slewing rollers before the horizontal top roller of continuous annealing line unit and polishing machine entrance.
The frame bottom is connect with pedestal by pin shaft.
Compared with prior art, the utility model has the beneficial effects that
The gauge length device for dotting overall structure of on-line proving finishing elongation percentage is simple, is easy to manufacture, easy to use, improves
The accuracy of continuity unit (hot galvanizing line, continuous annealing line) polishing machine elongation percentage calibration, while reducing because calibration polishing machine is made
At shutdown loss.Between slewing rollers before the present apparatus to be located to the horizontal top roller of continuous annealing line unit and polishing machine entrance, it can be ensured that
Idler wheel is close on the steel plate, the calibration of a stroke, operation letter be carried out using calibration salient point using handle by the accuracy of detection
Folk prescription is just.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the side view of the utility model.
In figure: 1- pedestal 2- bracket 3- idler wheel 4- handle 5- demarcates salient point 6- pin shaft 7- frame.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification, it should be noted that the utility model
Implement embodiment not limited to the following.
See that Fig. 1, Fig. 2, a kind of gauge length device for dotting of on-line proving finishing elongation percentage, the device are located at continuous annealing line unit water
Between slewing rollers before flat-top roller and polishing machine entrance, including bracket 2, idler wheel 3, handle 4, pedestal 1,2 bottom of bracket and pedestal 1
It is movably hinged, idler wheel 3 is connected at the top of bracket 2, handle 4 is fixed on 3 center of idler wheel, and the idler wheel 3 is equipped with calibration salient point
5。
Pedestal 1 is bolted between the slewing rollers before the horizontal top roller of continuous annealing line unit and polishing machine entrance, best
It is to be fixed on the frame 7 of rod.Wherein, 2 bottom of bracket can be connect with pedestal 1 by pin shaft 6.
The basic theory of polishing machine elongation percentage calibration measures the length L of known gauge length on strip first1, then measurement passes through
Gauge length L after crossing polishing machine rolling2, strip practical elongation percentage E=(L when can calculate finishing2-L1)/L1* 100%,
The elongation percentage E shown with polishing machine on-line checking2It compares, you can get it, and elongation percentage detects whether that accurate and deviation is
How much.
In use, the present apparatus is fixed at rear cold section of deviation rectification roller frame 7, when strip passes through, operator's hand handle hand
4, idler wheel 3 is pressed on strip, calibration salient point 5 extrudes fixed cycle (3 circumference of idler wheel, a present apparatus in dynamic belt steel surface
Using 1001mm) mark, as gauge length point, the period is L1.Continuous straight line is drawn in belt steel surface with marking pen simultaneously,
To facilitate personnel and tail portion inspection desk personnel at polishing machine that can find that the arrival of calibration mark is recorded and measured in time, survey
Magnitude is L2。
