Abstract
The invention relates to automatic correcting error control on converter tilting angle. Included is a PLC (Programmable Logic Controller) control, a rotary encoder and a master controller. The master controller is provide with four master controller control points; a first master controller control point is arranged in an area, which forms by the converter rotating clockwise 0-30 DEG towards a direction in front of the furnace; a second master controller control point is arranged in an area, which forms by the converter rotating 30-50 DEG anticlockwise towards a direction behind the furnace; a third master controller control point is arranged in an area, which forms by the converter rotating 340-360 DEG anticlockwise towards a direction behind the furnace; and a fourth master controller control point is arranged in an area, which forms by the converter rotating 270-300 DEG clockwise from furnace back to front. According to a technical scheme of the invention, control point can be arranged easily near each master controller control point angle, and are corrected by signal level and a rotary encoder of each master controller control point to eliminate deviation, so as to ensure needs of production technology and omit subsequent maintenance after debug.
Description
Technical field
The present invention relates to a kind of metallurgy industry steel-making converter processing unit, particularly relate to a kind of converter inclining angle automatic deviation correction control.
Background technology
The control of converter inclining angle is generally calculated turning angle by PLC according to the encoder pulse number; 0 degree place is provided with 2 master controller reference mark in converter; When the signal of 2 master controllers is 1 or 0, show that converter is in 0 degree, checks the converter angle of calculating through scrambler in view of the above.There is following shortcoming in this mode:
One, because the product performance of master controller determines that 2 masters at converter 0 degree place make the reference mark, want to debug into very difficulty of a spike, like this, certainly will cause in an angular regions, the converter angle of demonstration all is 0 degree.
Two, because the scrambler of converter deviation phenomenon might occur in rotary course, therefore, still possibly have angular error in non-0 degree zones such as tap holes, and this angular error to produce to influence meeting very big.
Summary of the invention
In view of this; Main purpose of the present invention is to provide a kind of converter inclining angle automatic deviation correction control, through the present technique scheme, the reference mark, reference mark can be set easily in this angle; Effectively guaranteed the needs of production technique aspect, debugging need not later maintenance after accomplishing.
In order to achieve the above object; Technical scheme of the present invention is achieved in that a kind of converter inclining angle automatic deviation correction control; Include PLC control, rotary encoder and master controller; Said master controller is provided with 4 master controller reference mark; The first master controller reference mark is arranged in 0 ~ 30 degree zone of converter clockwise direction stokehold direction rotation; The second master controller reference mark is arranged on counterclockwise to the stove rear in rotating 30 ~ 50 degree zones, and the 3rd master controller reference mark is arranged in 340 ~ 360 degree zones after behind stove, changeing counterclockwise, and the 4th master controller reference mark is arranged on clockwise behind the stove in 270 ~ 300 degree zones of stokehold direction.
Said rotary encoder is arranged on the auxilliary transmission shaft of converter inclining; Said master controller is arranged on the auxilliary transmission shaft of converter opposite side.
When the present invention adjusts work in actually operating; The image display key frame of converter inclining is provided with converter inclining " zero clearing " button; When operator shake 0 degree position through operation handle arm with converter; Press described " zero clearing " button, then in the PLC program automatically with scrambler in existing numerical value zero clearing, and simultaneously with the deviate and the zero clearing of current actual angle value at each master controller reference mark, front and back.
Next operator rotate the past stokehold of converter CW direction through operation handle arm; In 0 ~ 30 degree zone the first master controller reference mark is set; Make when converter is each rotates through this angle position from 0 degree clockwise toward the stokehold; The signal level of master controller all can become 1 from 0; This first master controller reference mark is passed through in converter at this moment for the first time, the PLC program note automatically the master controller signal from 0 become 1 o'clock scrambler more instantaneous encoded radio, and calculate the angle of position, the first master controller reference mark according to the whole circle encoded radio of scrambler.
In like manner; Be provided with in 30 ~ 50 degree zones counterclockwise to the stove rear to the rotating second master controller reference mark; Note in converter the encoded radio of the scrambler of the counterclockwise past stove rear of direction when turning round from the stokehold for the first time, and calculate the second master controller reference mark angle according to the whole circle encoded radio of scrambler through the second master controller reference mark
In like manner, be provided with in 340 ~ 360 degree degree zones counterclockwise to the stove rear to rotating the 3rd master controller reference mark.And calculate the 3rd master controller reference mark angle according to the whole circle encoded radio of scrambler.
In like manner, the 4th master controller reference mark that clockwise direction stokehold direction is rotated is set in 270-300 degree zone.And calculate the 4th master controller reference mark angle according to the whole circle encoded radio of scrambler.
After having noted above-mentioned 4 initial angles; Whenever converter rotation during through above-mentioned 4 master controller reference mark, PLC notes instantaneous encoded radio automatically, calculates corresponding angle according to this; This angle is compared with original initial angle; Draw corresponding angle deviation value, before next angle deviation value produces, PLC will check the converter angle automatically according to this deviate so.
The present invention is when the adjustment that practical operation is done; When rotation amounted to 4 master controller reference mark through positive and negative, front and back, deviation phenomenon did not take place in the umber of pulse of rotary encoder, noted the angle of this moment accurately; During the same master controller of after this each process reference mark; PLC automatically with angle modification for presetting angle, calculate deviation simultaneously, in the angle calculation of back, automatically revise and eliminate this deviation.
The present invention is as the main means of a check rotary encoder, and the characteristics of master controller are, and 1, owing to be hard link between master controller and the auxilliary axle of transmission, so deviation phenomenon can take place hardly; 2, master controller has a lot of output contacts, can satisfy the control needs fully; 3, the transition ratio that produces one 0 to 1 of master controller is easier to, but if produce one from 0 to 1 again from 1 to 0 sharp cutting edge of a knife or a sword then be difficult to debugging and come out.Therefore, rely on 2 adjacent masters about converter 0 degree to make the reference mark overlap in the past, judge that the methodic error of converter 0 degree is bigger.And, not high to the requirement of converter 0 degree in production reality, very high to the angle requirement of pushing off the slag on the contrary, 260 ~ 270 degree.。
Beneficial effect after the employing technique scheme is: a kind of converter inclining angle automatic deviation correction control; Through the present technique scheme, can near each master controller reference mark angle, be provided with very easily, and the signal level and the rotary encoder correction at each master controller reference mark of process; Eliminate deviation; Thereby guaranteed the needs of production technique aspect, debugging need not later maintenance after accomplishing.
