Description
Technical field
The invention belongs to a kind of automatic measuring device in the metallurgical machinery equipment field, is the on-line measuring device that is used for strip production board shapes (glacing flatness) such as cold-strip steel, aluminium strip, copper strips.
Background technology
Because the competition of cold belt steel international market is more and more fierce, the user requires also more and more higher thereupon to the strip shape quality of cold-strip steel.Force domestic manufacturer to have to introduce external plate profile instrument at high price, with the high-grade cold-strip steel of production high added value.And produce high-grade band steel, and must detect the online plate shape condition of rolled strip in real time, for the control of plate shape provides plate shape information accurately, thereby reach the purpose of controlling belt plate shape, rolling high-quality belt steel product better.Yet plate shape online automatic detection is a very difficult problem.Be that disturbing factor is many because testing environment is abominable on the one hand; Be because flatness defect has the form of expression of multiple complexity on the other hand.Therefore developing the novel high accuracy plate profile instrument that commercial Application requires that satisfies, is prerequisite and the key that improves the cold-rolled strip steel shape quality.
In the world, the research work that relevant plate shape is detected is very active, and people constantly seek new detection principle and detection method, satisfy the plate profile instrument of industrial production needs with research and development.With regard to method for detecting shape, nearly all physical quantity that can reflect strip shape quality, all attempted being used for the research of method for detecting shape, its main target is to seek simple in structure, small investment, fabrication cycle is short, accuracy of detection can satisfy production requirement detection method, as tensometer method, telemetry, electromagnetic method, vibration measuring method, optical method, thickness measuring method, thermometry etc.Generally, plate profile instrument is divided into contact and contactless two kinds of forms.In general, the structure of contactless plate profile instrument is simple relatively, and sensor is nonrotational element, and is easy for installation, does not have friction with belt steel surface, therefore can not scratch the band steel; But its plate shape signal is non-direct signal, and signal is handled easy distortion, is subject to all multifactor influences such as thickness of slab fluctuation, variations in temperature, vibration.The structure relative complex of contact plate profile instrument, but signal detecting method is more direct, signal is handled also than being easier to fidelity, and certainty of measurement is very high, now reaches ± 0.5I unit (actual product has 8I can meet the demands).Therefore, the contact plate profile instrument obtains iron and steel enterprise and payes attention to more widely and certain commercial Application in the cold-rolled strip steel shape context of detection.
Abroad since the sixties in last century, carry out the development of detecting instrument of flatness with regard to dropping into considerable man power and material, especially for core component---the research of plate-shaped sensing roller of plate profile instrument, this has become the research focus and emphasis of current cold rolled sheet shape research field.For the contact plate profile instrument that uses on the cold belt steel milling train, at present application feature has the air bearing formula Vidimon plate profile instrument of segmentation piezomagnetic plate profile instrument, Britain DAVY company of Sweden ABB AB and the BFI plate profile instrument of German SUNDWIG company relatively preferably.
The plate-shaped sensing roller of the segmentation piezomagnetic plate profile instrument of ABB AB mainly is made up of roll body, pressure sensor, collars, collars is the steel loop through quenching, its thickness is generally less than 10mm, adopt hot charging between collars and the roll body, so that certain precompression is arranged, the tension force of band is passed to pressure head by collars.But the architectural feature of this measuring roll makes the grinding accuracy of each collars internal diameter be difficult to guarantee unanimity, just is difficult to also guarantee that collars is consistent with the precompression between the roll body.Therefore, this segmented measuring roll in use, even the machining accuracy of measuring roll is very high, also can be often because variation of temperature, cause that the precompression between collars and the roll body changes, collars is produced relative rotation with respect to roll body, cause the collars changing of the relative positions to scratch band.The industrial applicability of the segmentation contact plate profile instrument of this feasible band collars or sleeve is limited greatly, especially for hightension cold belt steel milling train, adopts the segmented plate profile instrument very easily to cause the band steel to scratch, and has a strong impact on the surface quality of being with steel.
The center of the plate-shaped sensing roller of the air bearing formula plate profile instrument of DAVY company is an axle, roller shell is being overlapped in the outside, between axle and axle sleeve, leave certain interval, fill in the gap with pressure-air, when strap tension changes, cause that the gap between axle and the axle sleeve changes, make the pressure of gases at high pressure produce transient changing, thereby can detect the tension variation of band.But this plate profile instrument is very harsh to the requirement of working environment, need clean especially air, otherwise the air duct of measuring roll is easily blocked, and cisco unity malfunction, safeguards and assembles extremely difficultly, influences effective rolling time, increases maintenance cost.Thereby the commercial Application of this plate profile instrument also is very restricted, and is difficult to be widely used and promote, and the plate shape that generally only is used for laboratory experiment or small tension receiving coil rolled products such as aluminium strip, copper strips is detected.
The load-sensing unit of the BFI plate shape measurement roller of Germany SUNDWIG company is along the even interlaced arrangement of roller circumference, when whole roller detects under the condition of rotating, laterally the each point batch (-type) is measured the transmission signal, thereby can not reflect the plate shape condition perpendicular to the band steel cross section of rolling direction truly.
The development of China plate shape automatic control technology is later, and in the long term, people only carry out plate shape with range estimation sensation and operating experience and regulate and control, and are difficult to guarantee product quality, the bigger band as thin as a wafer of flakiness ratio especially, and lumber recovery is lower.Along with the require increasingly stringent of user to the cold-strip steel quality, domestic cold rolled strip steel production enterprise introduces plate profile instrument from external high price successively, expectation is by introducing advanced shape detection device, increase substantially the strip shape quality and the high added value of cold-rolled steel strip products, and then enlarge the competitiveness in the international market of enterprise.But from the practical situations of domestic big-and-middle-sized iron and steel enterprise, the industrial promotion effect of external plate profile instrument is also not fully up to expectations.The one, mostly there is said structure design defect problem in the contact plate profile instrument of introducing, is difficult to reasonably be properly settled always, and this has become the thorny problem of the current development of plate profile instrument in the world; The 2nd, it is very expensive that external plate profile instrument is introduced price, and maintenance cost and spare part expense are very high, and medium and small steel production enterprise generally all is difficult to bear high introduction expense and maintenance cost.This has limited the external plate profile instrument wide popularization and application of middle-size and small-size iron and steel enterprise at home, and after iron and steel corporation spent high expense to introduce complete plate profile instrument, the effect of using was barely satisfactory, need not hesitate to discard again, causes unnecessary waste.Overseas enterprise is to the blockade of plate profile instrument core technology and maintain secrecy, influenced domestic plate profile instrument research progress to a certain extent, still, also stimulated and impelled the domestic scientific research institutions must be by autonomous innovation, the plate profile instrument of development of new practicality is broken external monopolization to the practical plate profile instrument technology of industry.
Domestic from the beginning of the eighties in last century, some scientific research institutions begin to attempt developing the plate profile instrument that satisfies the industrial production needs.The one, by continuing to optimize design plate-shaped sensing roller structure, expect that it can enlarge the industrial applicability of homemade plate profile instrument in the medium-term and long-term stable operation of industrial production; The 2nd, break the technical monopoly of external plate profile instrument company, significantly reduce the sky high cost of import plate profile instrument, save a large amount of foreign exchanges; The 3rd, be expected to promote on the whole the plate shape control level of China's cold-rolling mill, improve the added value and the technology content of China's cold-rolled steel strip products, improve the competitiveness in the international market of China cold-strip steel enterprise.But the plate profile instrument of current domestic development rarely has the application example report that can be able to stable operation in industrial production, still belongs to blank.
In sum, although developed polytype contact plate profile instrument at present both at home and abroad, really can successful Application in production practices, and it is few to deserve to be called the plate profile instrument of high accuracy, stable performance.On the whole, the stability of current domestic and international plate profile instrument, reliability and accuracy all have much room for improvement, therefore, seek rational plate profile instrument measuring roll structure and signal processing mode, it is the thorny difficult problem that development can be satisfied the plate profile instrument of commercial Application requirement, this has become the bottleneck problem that the restriction plate profile instrument is extensively promoted on rolling mill for cold rolled steel strip, also be simultaneously the breach that current each research institution in the world develops the practical plate profile instrument of more infant industry.

Fig. 1 is an embodiment disclosed by the invention.The measuring roll 2 of plate profile instrument is installed on cold-rolling mill and exports former guide roller position.In transmission side bearing block 1 position, measuring roll 2 can link by shaft coupling and motor, utilizes frequency converter to realize the stepless speed regulation of plate-shaped sensing roller 2, so that be complementary with strip speed, transmission device perhaps is not installed, is realized the passive rotation of measuring roll by the band steel.In fore side bearing block 3 positions, measuring roll 2 connects segmentation fountain collecting ring 4, realizes the transmission of original plate shape signal.In fountain collecting ring 4 top cover plate and bottoms, connect the oil inlet pipe 6 and the oil return pipe 7 of automatic flushing device 8 respectively, realize the automatic cleaning of fountain collecting ring 4, lubricated and refrigerating function.Fountain collecting ring 4 outer ends connect photoelectric encoder 5 and (are commonly called as code-disc, model is chosen as ZKT-D120H30-102.4BM-C10-30E), be used to calculate, judge and transmit the rotational speed signal of measuring roll 2, connect signal processing system 11 by the quick connector 9 of code-disc.By outer connector 10 of the collecting ring on segmentation fountain collecting ring 4 tops and cable, plate-shaped sensing roller 2 detected plate shape signals are passed to DSP signal processing system 11 in real time, and then send software processing system 12 to, finally externally show on the equipment 13, printing, memory plane shape signal.
Elastomer 16 is embedded on the main roll body 17, and a plurality of (as 12) screw fixing operation side shaft head 14 and transmission side spindle nose 18 (see figure 2)s are adopted in main roll body 17 two ends.At two U type grooves of fore side spindle nose 14 outsides symmetry processing, stairstepping through hole of center processing, two U type groove places respectively process an inclined hole and are communicated with the centre bore of fore side spindle nose (14).In U type groove position, utilize arc gland 15 to realize that sealing connects.And in U type groove inside, the former limit of holding wire that the elastomer 16 that every road on the main roll body 17 (or every passage) symmetry is installed passes is with being in series, the anti-phase series connection of secondary, form differential circuit, this connection can obtain the signal output of higher sensitivity, and can eliminate the influence of precompression, can also reduce because the adverse effect that variations in temperature and centrifugal action etc. produce output signal to output signal.Circuit passes inclined hole and the spindle nose endoporus in the fore side spindle nose 14, is welded on the quick connector stitch.A center processing stairstepping through hole (macropore Φ 50, aperture Φ 8) of transmission side spindle nose 18, the unanimity of realization measuring roll inner and outer air pressure.
With the mode of piezomagnetic sensor 19 with interference fit, be pressed in the endoporus of elastomer block 20, form elastomer 16 (see figure 3)s.In order to increase the elastic characteristic of elastomer block 20, opening an axial rectangular through-hole near its outer surface, described rectangular through-hole is processed as circular arc (as Φ 4) near the place, two right angles of outer surface, place, two right angles rounding off in addition, in oblong aperture of the middle part of described rectangular through-hole processing, its width is slightly larger than the width of rectangular through-hole.Utilize the elastic characteristic of elastomer block 20, sensor 19 is applied certain pretightning force.The high temperature resistant wire of piezomagnetic sensor 19 then passes from the space, both sides of elastomer block 20 endoporus, and the lead-in wire that prevents the piezomagnetic sensor 19 in the measuring roll 2 of high speed rotating vibration takes place or reverses, and influences the signals collecting precision or causes dropout.Elastic cushion block 23 needs to guarantee that the arcwall face external diameter is consistent with main roll body 17 internal diameters, so that closely contact with main roll body 17 inner surfaces; In order to increase the elastic characteristic of elastic cushion block 23,, make it better near main roll body 17 inner surfaces at elastic cushion block 23 centers processing through hole.By two O RunddichtringOs 21, two M8 trip bolts and spring pad 22 and two elastic cushion blocks 23, the elastomer that piezomagnetic sensor 19 and elastomer block 20 are combined into is embedded in the rectangular channel on the main roll body 17, fastening is an integral body, thereby can effectively avoid traditional plate profile instrument of sleeve or collars being installed because thermal expansion scratches the defective of belt steel surface.Wherein the circumferencial direction of elastomer block 20 and main roll body 17 generally need remain with minim gap (as 0.01mm), and the localized heat stress when preventing main roll body 17 heat expansions causes main roll body 17 rectangular channels outside and elastomer block 20 contact positions heat fatigue to occur and destroys.
