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 Winding single vertical roller flat by using fine wireThin line length L measured by head collar2(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 the equipment calibration technology field, relate in particular to a kind of scaling method that is used for rolling mill for hot rolled planks and strips edger roll opening degree.
Background technology
Edger roll is that the hot-rolled sheet strip steel milling train carries out the rolling main mechanical in side to the strip steel, and width control and made-up belt centering aspect are played crucial effect.Therefore, when each maintenance back or edger roll fault, all need the opening degree (being roll gap) of opposite roller to demarcate again.
At present, measuring the common method that edger roll opening degree value taked is:
1, after stopping rolling, survey crew stands on the transition backplate of edger roll, measures the edger roll center line apart from active side edger roll roll surface distance L
WS, apart from transmission side edger roll roll surface distance L
DS
2, every side add edger roll roller footpath d half as calibration value, that is: L
WS+ d/2, L
DS+ d/2.
3, demarcate.
Adopt said method,, have following drawback though seem simple:
The one, dangerous when demarcating operation.Because edger roll is arranged between De-scaling box and the milling train, working space is narrow and small, and no safety guide rail, the survey crew edger roll of can only leaning to one side to get into leans on two legs to support and could stand reluctantly, and it is very inconvenient to measure.The 2nd, efficiency of measurement is low, and 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 zone is very high, and survey crew can't get into edger roll and measure, and it is inaccurate to cause the edger roll opening degree to demarcate, and influences the precision of width of plate slab control.
Summary of the invention
The present invention aims to provide a kind of simple and convenient, and is safe and practical, can fast, accurately calibrate the edger roll opening degree, thereby save time, the milling train edger roll opening degree scaling method with the width control accuracy of increasing work efficiency.
For this reason, the solution that the present invention taked is:
A kind of milling train edger roll opening degree scaling method is characterized in that concrete grammar and step are:
1, survey crew stands in edger roll next door, with two edger roll homalocephalus collar places of a fine rule winding, and the length L of measuring fine rule afterwards and being twined
1
2, twine the single edger roll homalocephalus collar with fine rule again, the length L of measuring fine rule afterwards and being twined
2
3, measure the distance of rolling centerline edger roll bearing housing edge with board foot respectively, obtain L apart from both sides
3And L
4
4, demarcate: demarcating on the picture, the total opening degree that calibrates between two edger rolls is:
Total opening degree=(L
1-L
2)/2
The opening degree of left side 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 the opening degree of edger roll opening degree (gap values between rollers) and left and right sides edger roll easily and fast, exactly; And find out the difference between the edger roll opening degree of the left and right sides; 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, can increase work efficiency and roll the precision of back steel plate again.Simultaneously, can eliminate safe hidden trouble, avoid personal injury accident.
Description of drawings
Fig. 1 is L
1The measuring method sketch map.
Fig. 2 is a milling train edger roll opening degree scaling method sketch map.
Among the figure: edger roll homalocephalus cover 1, the edger roll homalocephalus collar 2, fine rule 3, right edger roll 4, left edger roll 5.
The specific embodiment
Be example with the 1580mm milling train below, the present invention is described further.
At first, on edger roll control picture, the edger roll opening degree is opened to 1200mm.
Survey crew stands in the edger roll next door, and the edger roll homalocephalus collar 2 places with a fine rule 3 twines two edger roll homalocephalus covers 1 measure the length L that fine rule 3 is twined afterwards
1=2800 mm.
Twine the single edger roll homalocephalus collar 2 with fine rule again, the length L of measuring fine rule afterwards and being twined
2=500 mm.
Then, measure the distance L of rolling centerline with board foot apart from left edger roll 5 bearing housing edges
3=800 mm; Measure the distance L of rolling centerline again apart from right edger roll 4 bearing housing edges
4=798 mm.
The total opening degree of calculating edger roll is that the distance between two edger roll centers is: total opening degree=(L
1-L
2)/2=(2800-500)/2=1150 mm.
Demarcate: demarcating on the picture, is that left edger roll 5 axis are demarcated apart from the distance between the rolling centerline and are with 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 demarcation between the 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 big 2 mm.
