Abstract
The invention relates to an online continuous roller hole pattern misplacement detection instrument and method. The online continuous roller hole pattern misplacement detection instrument comprises an upper hole pattern template and a lower hole pattern template which are provided with part cambered surfaces corresponding to continuous roller hole patterns and jointly form the continuous roller hole patterns. The instrument is characterized in that contact faces of the upper hole pattern template and the lower hole pattern template adopt a form that a slider is matched with a slideway, a zero position mark is arranged at the center of one of the hole pattern templates, the other hole pattern template is provided with a reference graduated ruler mark corresponding to the zero position mark, and multiple through holes convenient for hand-holding are distributed in faces of the upper hole pattern template and the lower hole pattern template. The instrument is simple in structure, reliable in use and simple to operate; hole pattern misplacement is adjusted and eliminated according to measured misplacement numeric value, so that the problem that existing continuous roller hole pattern misplacement is less prone to being timely found and dealt is solved, wall thickness accuracy of continuously rolled steel pipes is improved greatly, defective product rate is lowered remarkably, and production cost is saved.
Description
Technical field
The present invention relates to hot rolled seamless steel tube technology, particularly a kind of online tandem rolling roller pass dislocation detector and detection method.Be applicable to hot rolled seamless steel tube factory two roller tandem rolling tube unit pass dislocation and detect adjustment.
Background technology
Two roller tandem rolling tube units such as MPM continuous rolling-tube unit uses extensively in China, MPM continuous rolling-tube unit has Hengyang 89 tandem rolling in China, Baosteel 140 tandem rolling, Tianjin 250MPM, packet header 180MPM, Anshan iron and steel plant 159MPM, Lyceum carrys out this 250MPM and 159MPM, the tens cover units such as the imperial 180MPM of ink, high with automatization level as retained mandrel tandem rolling roller pipe unit, output is high, wall thickness accuracy height is famous, but along with passage of time, memorial archway slide plate, locating piece weares and teares, the ageing equipment problems such as the large and bearing block bore hole wearing and tearing in roll bearing gap, online tandem rolling roller axial location is caused to change, thus cause pass to misplace (see Fig. 3).Because tandem rolling roller pass is formed by connecting by multistage arc, roll gap place chamfering is large, only be difficult to find with people's naked eyes, so just cause roll gap place wall thickness on one side, wall is thin on one side, and this change has heredity, though have certain improvement through the wall thickness of frame rolling below but still above-mentioned defect can not be eliminated completely, if it is even more serious that pass dislocation occurs in finishing stand problem, mandrel mill-made shell wall thickness there will be one thick, , a thin phenomenon, mandrel mill-made shell wall thickness extreme difference increases, wall thickness accuracy reduces, fished pipe wall thickness accuracy is caused not meet standard-required, thus percent defective improves, production cost increases.According to the applicant understood, the effective pass for two roller tandem rolling tube units dislocation checkout gear and method is not also had at present.
Summary of the invention
The object of the invention is to provide that a kind of structure is simple, the online tandem rolling roller pass dislocation detector of service-strong and detection method, according to the adjustment of measurement dislocation numerical value, eliminate pass dislocation, fundamentally solve the dislocation of existing tandem rolling roller pass not easily by the problem of Timeliness coverage process, simple to operate, greatly improve mandrel mill-rolled steel pipe wall thickness accuracy, significantly to reduce the number of rejects and seconds rate, save production cost.
Technical scheme of the present invention is:
A kind of online tandem rolling roller pass dislocation detector, comprise upper and lower pass template, upper and lower pass template has the part cambered surface corresponding with tandem rolling roller pass respectively and both form tandem rolling roller pass jointly, it is characterized in that: the contact surface of upper and lower pass template adopts the fit form of slide block and slideway, the pass center of a pass template is provided with zero mark, the corresponding zero mark of another pass template is provided with reference to scale markings, the plate face of upper and lower pass template is distributed with the multiple through holes being convenient to hold.
Above-mentioned online tandem rolling roller pass dislocation detector, the described unit with reference to scale markings is 1mm.
Apply an online tandem rolling roller pass dislocation detection method for above-mentioned detector, it is characterized in that, comprise the steps:
1), by tandem rolling roller to be measured load rack locking successively, adjacent rack does not first fill roller;
2), upper and lower pass template is assembled into one, staff is in adjacent rack position, point and put into tandem rolling roller pass to be measured through the pass template of holding with a firm grip of the through hole on upper and lower pass template, adjustment tandem rolling roller position makes the cambered surface of tandem rolling roller pass and upper and lower pass template fit, under tandem rolling roller effect, upper and lower pass template generation relative sliding;
3), check that zero mark is with reference to the displacement in scale markings and reading numerical values, namely this numerical value be pass axile displacement numerical value.
The invention has the beneficial effects as follows: the pass dislocation detector of the application is simple and practical, detection method is simple and reliable, the pass of the application dislocation detector is put into online tandem mill pass, pass dislocation numerical value is read by referring to scale markings, then operator can directly be adjusted tandem mill locating piece position according to dislocation numerical value or be adjusted by shimming, solve tandem rolling roller pass problem of misalignment, thus improve Continuous Seamless Tube Mill wall thickness accuracy, holding tube wall thickness is even, save a large amount of postorder adjustment work, that detects dislocation carries out simultaneously in time, also reduce percent defective, save production cost.
