Description
Technical field
The utility model relates to thickness measurement technique, particularly detects the measurement mechanism that the thin gauge sheet metal transverse gage distributes.
Background technology
It is one of important indicator of judging thin plate plate shape that the section thickness of flat cold-rolled sheet distributes, and to rolling the measurement of back band steel at the typical position of width thickness, is that the production technology personnel judge the important criterion of rolling back strip shape quality quality especially.
Usually for the technology of production scene being improved or being improved, the band steel transverse gage under some current rolling mill practice of understanding that must be detailed distributes the cold rolling technology personnel, provides criterion accurately for formulating corresponding corrective measure.Based on this, production technology personnel are badly in need of a kind ofly carrying out measurer for thickness accurately to the thickness distribution of band steel horizontal section.Because the average thickness values of flat cold-rolled sheet is very little, usually between 0.1mm～1.0mm, and the thickness difference of the horizontal section of steel plate remains on the following level of 20um usually, especially at the comparatively contiguous position of strip width direction, for example the distance band a certain side of steel (as active side or fore side) limit portion 15mm place thickness and poor with the thickness at lateral extent strip edge portion 100mm place, its difference are usually in the level of ± 10um.For accurately obtaining this thickness difference level, the certainty of measurement level of measurement mechanism must remain on ± 1.0um.High-level certainty of measurement like this requires measurement mechanism is required very strict.For the thickness scanning in the cross section that obtains the cold conditions thin gauge sheet metal distributes, the main both at home and abroad at present two class metering systems that adopt, a kind of is contact type measurement, the contact of touch sensor is directly contacted with the upper and lower surface of measuring object, and apply certain contact pressure, obtain the one-tenth-value thickness 1/10 in space by computing; Another kind is a non-contact measurement, promptly adopt modes such as ultrasonic wave, current vortex and laser to realize non-contact thickness measuring to thin gauge sheet metal, for the measuring object of thickness at 0.1mm～1.0mm, usually select the laser measurement mode for use, promptly utilize laser measuring head to carry out motion scan, realize the section thickness of steel plate is measured in band steel cross section.
Yet the certainty of measurement of this dual mode still is difficult to satisfy the certainty of measurement demand of the cross sectional thickness difference of thin gauge sheet metal, it is directly related that for example the certainty of measurement of contact is contacted the factor such as case hardness, roughness of stress level, measuring object, is difficult to realize the measurement of required precision; And the mobile laser scanning survey, then because the slight vibrations of laser head cause scanning result always to have a certain amount of deviation in the moving process, this departure is usually more than 2um, so its precision still is difficult to meet the demands.
At this specification requirement, by consulting relevant technical patent both at home and abroad as can be known: Chinese patent CN1356186, CN1031758, CN2349537, CN1800776 and CN2206945 disclose a series of devices that utilize laser that the tabular target in the motion is carried out online detection, its design concept is very advanced, yet be limited to the maximum certainty of measurement of current laser measuring head and to the capturing ability of kinetic measurement object, limited the certainty of measurement under the motion state greatly, can't reach ± precision level of 1.0um; Simultaneously, the dynamic laser measurement mechanism of design such as domestic patent CN2494972, its measuring object has bigger physical dimension difference usually, and movement velocity is lower, so can obtain relative accuracy preferably.Yet, for the thick difference measurements in the cross section of flat cold-rolled sheet, the but suitable survey tool of neither one still.
