Technical field
The present invention relates to high speed wire rod finishing block, relate in particular to high speed wire rod finishing block centering method.
Background technology
Wire rod is one of important rolled products, and it occupies the status of particular importance in national economy, because delivering goods with coil form, therefore be called again wire rod.The feature of wire rod is thin and grow, so dimensional accuracy and evenly control is very important in section and length in the operation of rolling.
According to the requirement of production technology, generally a set of milling train is divided into several tandem rolling units, between each unit without continuous rolling relationship.Generally be divided into roughing unit, intermediate mill and mm finishing mill unit etc.The maximum mill speed of rod-rolling mill is called high-speed rod-rolling mill during higher than 40m/s, is characterized in: at a high speed, single line, without turning round, Minimal Tension, combining structure, tungsten carbide tool collars and automation.
The Main Function of roughing is to make stock obtain preliminary compression and extension, obtains that temperature is suitable, section configuration is correct, size is qualified, surface is good, and broken end rule, length are applicable to the rolled piece of technological requirement; In roll and the effect of pre-finish rolling is the cross dimensions that continues reduction rolled piece, for mm finishing mill unit provides the section configuration of all needs of mill product wire rod correct, size accurately and along total length cross dimensions evenly, without material in the middle of inherence and blemish; Mm finishing mill unit adopts nothing at a high speed to turn round unit, between finishing mill and Laying head, reducing sizing mill is set, and rolled piece shuts out by the cooling reducing sizing mill that enters of water cooling plant and is rolled from finishing mill, then enters Laying head.
Wherein the accuracy of alignment at mm finishing mill unit center, for unit operation stability, is piled the minimizing of steel fault, and wire quality is controlled extremely important.Whole mm finishing mill unit length reaches 60 meters, and traditional optical alignment measurement method seems that for so large measurement length precision is low, inefficiency, cannot meet the requirement of fast mill.
Summary of the invention
The present invention is intended to solve the defect of traditional optical alignment measurement method, and a kind of center-aligning method of high-speed wire stock finishing mill is provided.Method of the present invention realizes (whole piece finishing line) quick high accuracy laser alignment measurement within the scope of 60 meters.
The present invention is achieved in that
, it comprises:
(1) demarcate intermediate base on schedule: according to original installation reference line, before and after reducing sizing mill, two of center reference points are set respectively, two datum marks overlap with equipment mounting center line;
(2) arrangement of transmitter: it comprises generating laser fixing tool, to guarantee that generating laser laser center and whole piece roll line centre deviation are controlled at grade, and finely tunes as setting up one and approximate with rolling center parallel laser line, creates conditions;
(3) foundation of laser quasi straight line: first select the datum mark as measuring basis, take original reference for installation or online apparatus characteristic point is benchmark, adopt the central point of permanent plant as benchmark, on datum mark, place respectively laser pickoff, adopt near-end deviation adjusting transmitter displacement, the method of far-end deviation adjusting transmitter angle, progressively adjusts the direction of laser rays, guarantees that laser beam overlaps with datum line;
(4) measurement of position: set up desirable rolling centerline by (1)-(3) step, now laser pickoff is placed in and on different measuring points, carries out a demarcation for position centre deviation, each Point Measurement 2 times, the average of measurement result is as final result.
Described center-aligning method of high-speed wire stock finishing mill, it also comprises:
(5) coordinate system conversion: after the three-dimensional spatial information collection of all measurement points position completes, according to the needs of device analysis again selected reference, by Coordinate Conversion obtains the coordinate under new coordinate system a little.
Described center-aligning method of high-speed wire stock finishing mill, described two datum marks all overlap on height direction, left and right directions with equipment mounting center line.
Described center-aligning method of high-speed wire stock finishing mill, the permanent plant as benchmark in described (3) comprises finishing mill collar and slewing rollers.
Described center-aligning method of high-speed wire stock finishing mill, in described (4), measures on 0 ° and 180 ° of both directions the double measurement of each some position.
Described center-aligning method of high-speed wire stock finishing mill, in described (2), described generating laser fixing tool comprises in firm banking that the transmitter connecting portion that is all connected is consistent with rolling mill guiding with shape and frock body with four connecting through holes.
The present invention is high accuracy alignment measurement within the scope of whole piece finishing line rapidly, for improving product quality, provides sound assurance, and meanwhile, operating efficiency of the present invention obviously improves compared with conventional method, greatly reduces equipment downtime.
The specific embodiment
, it comprises:
(1) demarcate intermediate base on schedule: according to original installation reference line, before and after reducing sizing mill, two of center reference points are set respectively, two datum marks overlap with equipment mounting center line;
