Conventional traditional measurement method comprises two kinds: the first: rely on the displacement transducer of housing screw or hydraulic cylinder for reduction system device to carry out roller system drafts and measure; The second: rely on the displacement transducer of the hydraulic pressure adjustment unit device between screw and upper stressed frame to carry out roller system drafts and measure.
Above-mentioned two kinds of measuring methods are all measure drafts by indirect inspection; During indirect inspection, in the setting value of roll gap and measuring process, the numerical value of institute's use sensor is not same numerical value; Namely the gap values between rollers that indirect inspection is extrapolated does not conform to the actual conditions, and in aligning model, visualize is that drafts is different.
For 11 roller straighteners, in varied situations, under the precondition of given strip width, thickness, yield strength, excessively lengthening coefficient, according to aligning model, provide different drafts; Observe when different drafts, the situation of change of straightening force, the 3rd roller moment of torsion, remnant curvature:
Table 1-1, during slab aligning, when different drafts, the situation of change of straightening force, the 3rd roller moment of torsion:
As can be seen from table 1-1, the impact of minor variations on straightening force of drafts is larger; The minor variations of drafts is very large on the impact of the 3rd roller moment of torsion, thus threatens the safety of spindle.
Table 1-2, when optimizing aligning, when different drafts, the situation of change of remnant curvature:
As can be seen from table 1-2, the minor variations of drafts, plays very important effect to remnant curvature.
Therefore by conventional traditional measurement method, certain error is all there is not due to the numerical value of institute's use sensor in the setting value of roll gap and side amount process in the drafts measured for same numerical value, cause the slight error of drafts, thus cause the change of straightener straightening force, the remnant curvature change etc. of sheet material; Affect the production of whole straightener.
Roller system of straightening machine drafts direct measuring method of the present invention has following outstanding advantage relative to traditional measurement method: roller system of straightening machine drafts direct measuring method first of the present invention can realize the direct measurement to straightening roll press quantity.Avoid loaded down with trivial details calculating.Simultaneously measurement result is only subject to the impact of measure error, and do not affect by the alignment error of equipment the drafts precision therefore obtained higher, accuracy is higher.Thus avoid the parameters of the slight error of drafts to straightener to impact.
Secondly roller system of straightening machine drafts direct measuring method of the present invention, by calculating theoretical drafts, by theoretical drafts h
3and adjustment height h
1calculate amount of measurement error Δ h
4.By amount of measurement error Δ h
4to measurement drafts h
2result revise, make measurement result more accurate.
Last roller system of straightening machine drafts direct measuring method of the present invention belongs to a kind of method directly measuring drafts, is non-obvious relative to traditional measuring method, and not deriving by traditional measuring method draws; Simultaneously because the traditional measurement method of routine is indirect measurement method, therefore roller system of straightening machine drafts direct measuring method neither the technological means of those skilled in the art's routine.
In order to the corrosion preventing position measurement element 2 to be subject to water, iron scale in the process measured, further, on position measuring cell 2, protective sleeve 3 is installed in step.Protected by protective sleeve 3 pairs of position measuring cells 2, the pollutant avoided in external environment causes corrosion to position measuring cell 2, it also avoid external environment simultaneously and causes interference to measurement result.Therefore can service life of extended position measuring cell 2 by arranging protective sleeve 3, effectively can ensure certainty of measurement simultaneously.
