Abstract
The invention discloses a method for multiplexing a box-shaped hole-pattern roller, which comprises the following steps of: measuring the wearing capacity; correcting hole patterns; manufacturing a template; modifying a turning tool; performing installation and debugging; and performing upper and lower passes of balance calculations to determine the corrections of upper and lower roller groove bottoms and side wall inclined planes and adjust roll gap values. The method breaks through the traditional operating method of 'the fixation of the hole patterns, the template and the turning tool', and is used for maintaining the whole process from the new opening of a roller to the discarding of the roller, and combining the wear condition of the roller to dynamically control the hole patterns. The multiplexing of each time corrects the hole patterns according to the wearing capacity, and the sizes of the template and the turning tool are correspondingly changed along with the multiplexing of each time to adjust the roll gap values at the same time. The method ensures that the hole patterns of each pass are used normally, bars are straightened not to fall steel, no cold finished steel bars are generated, the lumber recovery is improved, the notch depth can be reduced, the turning time is increased, and the service life of the roller is prolonged.
Description
[technical field]
The present invention relates to be used for the method that the concave roll reparation of steel rolling is reused, be applicable to box pass blooming mill row and the arc under casing shape pass finishing mill line of billet size greater than 100 sides.
[background technology]
Roll Pass confirms that new open rolling roller technical process is when new open rolling roller design: up and down the passage EQUILIBRIUM CALCULATION FOR PROCESS, draw pass figure, join rod figure, make model, make lathe tool, turning roll, last Installation and Debugging.Roll rolls the hole side-walls concentrated wear must take place after using, and roll need be changed to repair and could continue to reuse.Traditional multiplexing method is: utilize intrinsic pass, model and lathe tool, turning roll cylindrical is repaired pass, is called the operational method of " pass model lathe tool three is fixing ", keeps the overall process that new open rolling roller is scrapped to roll.Because it is big to roll the sidewall inclined-plane wearing and tearing in hole; In order to reduce cylindrical turning amount (conference of turning amount is quickened roll and scrapped), generally all adopt the lathe tool move left and right to repair pass, pass bottom land after the reparation and opening are all greater than initial spl; The front and back passage can't be carried out EQUILIBRIUM CALCULATION FOR PROCESS; Cause no side pressure rolling, bar shaped is out of control, cold increase.The worker is in order to reduce down steel in adjustment, tightens up the import guide device, makes rolled piece produce serious scratch.
[summary of the invention]
The present invention proposes a kind of method for multiplexing box-shaped hole-pattern roller, is intended to overcome the deficiency that traditional multiplexing method exists.
Technical scheme of the present invention is: a kind of method for multiplexing box-shaped hole-pattern roller is characterized in that comprising the steps:
1) measures wear extent;
2) revise pass, comprise the correction and adjustment gap values between rollers of confirming up-down rollers bottom land and sidewall inclined-plane through passage EQUILIBRIUM CALCULATION FOR PROCESS up and down;
3) make model;
4) revise lathe tool;
5) turning roll;
6) Installation and Debugging.
As further, when confirming up-down rollers bottom land correction, the monolateral correction of up-down rollers is at least greater than 1 millimeter of wear extent, and maximum is no more than 1.5 times of wear extent; When confirming sidewall inclined-plane correction, the correction on one-sided inclined-plane is at least greater than 0.5 millimeter of wear extent, and maximum is no more than 1.5 times of wear extent, and gradient increases 1.5-2%.
As further; During the adjustment gap values between rollers; Set gap values between rollers upper limit gap values between rollers, middle limit gap values between rollers and lower limit gap values between rollers, upper limit gap values between rollers is minimum pass profile height about 1/3rd of this roll configuration, and middle limit gap values between rollers is 3/4ths of a upper limit gap values between rollers; The lower limit gap values between rollers is 1/2nd of a upper limit gap values between rollers, during each multiplexing roll then from big to small successively circulation take one of them gap values between rollers in turn.
The present invention breaks through the operational method of traditional " pass model lathe tool three is fixing ", is applied to keep the overall process that new open rolling roller is scrapped to roll, and its characteristics are embodied in the design concept of introducing new open rolling roller, in conjunction with the roll wear situation, and dynamic control pass.Multiplexingly each time all revise pass according to check for wear, model and lathe tool size change thereupon, adjust gap values between rollers simultaneously, can make roll that the effect of repairing sth. old and make it as good as new is arranged.Repaired roller uses amended model and lathe tool, the definite up-down rollers bottom land and the correction processing on sidewall inclined-plane according to passage EQUILIBRIUM CALCULATION FOR PROCESS up and down, and it is normal to guarantee that each passage pass uses, and the straight and upright steel that do not fall of bar shaped does not produce cold, improves lumber recovery.Every multiplexingly once need design again once, though more loaded down with trivial details than traditional multiplexing method, can reduce cutting groove depth, increase the roll turning number of times, prolongation roll service life.
[specific embodiment]
Do further detail explanation below in conjunction with embodiments of the invention.
With roll configuration of 100 sides is example, and new open rolling roller is according to traditional design method, according to draw pass figure, join rod figure, model designs and produces, lathe tool design and fabrication, turning roll, the flow process of adjustment is installed, come into operation until qualified products.
Through using after a while, pass bottom land and sidewall wearing and tearing go beyond the limit, and then need pull down the roll reparation.Change in order in subsequent reuse, to adopt dynamic pass to adapt to pass with the adjustment roll gap, new open rolling roller gap value need be amplified near 1/3rd of pass minimum cross section height, considers to be convenient to calculate and gets 32 millimeters and as upper limit gap values between rollers nearby; Middle limit gap values between rollers is 3/4ths, 24 millimeters of upper limit gap values between rollers; The lower limit gap values between rollers is 1/2nd, 18 millimeters of upper limit gap values between rollers.During each multiplexing roll then from big to small successively circulation take one of them gap values between rollers in turn.
Repaired roller carries out as follows each time:
1) measures wear extent.
2) revise pass.Confirm the correction and adjustment gap values between rollers on up-down rollers bottom land and sidewall inclined-plane through passage EQUILIBRIUM CALCULATION FOR PROCESS up and down.
3) make model;
4) revise lathe tool;
5) turning roll;
6) Installation and Debugging.
Each repaired roller, all fibrous root uses different models and lathe tool according to pass changes.
When confirming up-down rollers bottom land correction, the monolateral correction of up-down rollers is at least greater than 1 millimeter of wear extent, and maximum is no more than 1.5 times of wear extent; When confirming sidewall inclined-plane correction, the correction on one-sided inclined-plane is at least greater than 0.5 millimeter of wear extent, and maximum is no more than 1.5 times of wear extent, and gradient increases 1.5-2%.The adjustment gap values between rollers: it is 32 millimeters that new open rolling roller uses upper limit gap values between rollers; The limit gap values between rollers was 24 millimeters during reparation was used for the first time, and depth of groove increases by 4 millimeters; Repair for the second time and use the lower limit gap values between rollers, 16 millimeters, depth of groove is increasing by 4 millimeters.When repairing again, 16 millimeters of turning roll cylindricals, recovering the SC service ceiling gap values between rollers is 32 millimeters.So circulation is scrapped until roll.
Blank is greater than the reparation of 100 sides' box pass, and method step is identical, and the upper limit that different is, middle limit, lower limit gap values between rollers change because of billet size.The bar milk blank is less than inapplicable the present invention of box pass of 100 sides, water chestnut square hole, ellipse side, the also inapplicable the present invention of hexagonal side's diplodal.
