Abstract
The invention provides a method for calibrating the opening degree of a vertical roll of a rolling mill, which measures the length L of a thin wire by winding the thin wire around two flat-head lantern rings of the vertical roll1(ii) a Then measuring the length L of the thin wire by winding the thin wire on a single vertical roller flat head lantern ring2(ii) a Respectively measuring the distance L between the rolling center line and the edge of the vertical roll bearing box at two sides3And L4(ii) a By the formula (L)1－L2）/2、（L1－L2+2×L3－2×L4) /4 and (L)1－L2－2×L3+2×L4) And/4, respectively obtaining the total opening degree and the opening degrees of the left vertical roll and the right vertical roll. The invention can conveniently, quickly and accurately mark the opening degree of the vertical roll, thereby providing accurate foundation conditions for controlling the width of the steel plate and centering the strip billet, saving the measurement and maintenance time, and improving the working efficiency and the precision of the rolled steel plate. Meanwhile, the potential safety hazard can be eliminated, and personal injury accidents are avoided.
Description
Technical field
The invention belongs to equipment calibration technology field, relate in particular to a kind of scaling method for rolling mill for hot rolled planks and strips edger roll opening degree.
Background technology
Edger roll is that hot-rolled sheet strip steel milling train carries out the main mechanical of side rolling to Strip, and width control and made-up belt centering aspect are played a very important role.Therefore,, when overhauling rear or edger roll fault, all need the opening degree (being roll gap) of opposite roller again to demarcate at every turn.
At present, the common method that measurement edger roll opening degree value is taked is:
1, after stopping rolling, survey crew stands on the transition backplate of edger roll, measures edger roll center line apart from active side vertical rolls face distance L
wS, apart from transmission side vertical rolls face distance L
dS.
2, every side add vertical rolls footpath d half as calibration value, that is: L
wS+ d/2, L
dS+ d/2.
3, demarcate.
Adopt said method, although seem simple, have following drawback:
The one, dangerous while demarcating operation.Because edger roll is arranged between De-scaling box and milling train, working space is narrow and small, and without safety guide rail, the survey crew edger roll of can only leaning to one side to enter, supports and could stand reluctantly by two legs, and it is very inconvenient to measure.The 2nd, measure efficiency low, Measuring Time is long.The 3rd, in the normal operation of rolling of milling train, edger roll breaks down needs timing signal, and the temperature in edger roll region is very high, and survey crew cannot enter edger roll and measure, and causes edger roll opening degree to demarcate inaccurate, affects the precision that width of plate slab is controlled.
Summary of the invention
The present invention aims to provide a kind of simple and convenient, safe and practical, can be fast, accurate calibration goes out edger roll opening degree, thus save time, increase work efficiency and the vertical roll of rolling opening degree scaling method of width control accuracy.
For this reason, the solution that the present invention takes is:
A vertical roll of rolling opening degree scaling method, is characterized in that, concrete grammar and step are:
1, survey crew stands in edger roll side, with a fine rule, is wound around two edger roll homalocephalus collar places, measures afterwards the length L that fine rule is wound around
1;
2, with fine rule, be wound around the single edger roll homalocephalus collar again, measure afterwards the length L that fine rule is wound around
2;
3, the distance of measuring respectively rolling center line-spacing both sides vertical roll bearing box edge with board foot, obtains L
3and L
4;
4, demarcate: demarcating on picture, the total opening degree calibrating between two edger rolls is:
Total opening degree=(L
1-L
2)/2
The opening degree of left edger roll is:
（L
1－L
2?+2×L
3－2×L
4）/4；
The opening degree of right edger roll is:
（L
1－L
2?－2×L
3+2×L
4）/4。
Beneficial effect of the present invention is:
Adopt the present invention's scheme, can calibrate easily and fast, exactly the opening degree of edger roll opening degree (gap values between rollers) and left and right edger roll, and find out the difference between the edger roll opening degree of left and right, thereby for the centering of steel plate width control and made-up belt provides accurately basic condition, both can save and measure and the repair time, the precision that can increase work efficiency and roll again rear steel plate., can eliminate safe hidden trouble meanwhile, avoid personal injury accident.
Accompanying drawing explanation
Fig. 1 is L
1measuring method schematic diagram.
Fig. 2 is vertical roll of rolling opening degree scaling method schematic diagram.
In figure: edger roll flat head sleeve 1, the edger roll homalocephalus collar 2, fine rule 3, right edger roll 4, left edger roll 5.
The specific embodiment
1580mm milling train take below as example, and the invention will be further described.
First, on edger roll control interface, edger roll opening degree is opened to 1200mm.
Survey crew stands in edger roll side, is wound around the edger roll homalocephalus collar 2 places of two edger roll flat head sleeves 1 with a fine rule 3, measures afterwards the length L that fine rule 3 is wound around
1=2800 mm.
With fine rule, be wound around the single edger roll homalocephalus collar 2 again, measure afterwards the length L that fine rule is wound around
2=500 mm.
Then, with board foot, measure the distance L of the left edger roll of rolling center line-spacing 5 bearing housing edges
3=800 mm; Measure again the distance L of the right edger roll of rolling center line-spacing 4 bearing housing edges
4=798 mm.
The total opening degree of calculating edger roll i.e. distance between two edger roll centers is: total opening degree=(L
1-L
2)/2=(2800-500)/2=1150 mm.
Demarcate: demarcating on picture, is that left edger roll 5 axis are apart from the distance calibration between rolling centerline by the opening degree of left edger roll 5:
（L
1－L
2?+2L
3－2L
4）/4=（2800－500+2×800－2×798）/4=576（mm）。
The opening degree of right edger roll 4 is that right edger roll 4 axis are apart from the distance calibration between rolling centerline:
（L
1－L
2－2L
3+2L
4）/4=（2800－500－2×800+2×798）/4=574（mm）。
Obviously, the opening degree of left edger roll 5 than the opening degree of right edger roll 4 large 2 mm.
