Description
Technical field
The present invention relates to electrical drive control system field, flying shear miscut after bar breaking down is prevented more specifically to one kind
The control method cut.
Background technique
Bar generally requires carry out flying shear after going out well, in the prior art often through control milling train muzzle velocity, metal
Detector is sheared with computational length according to fixed length, but since supplied materials length is unstable, and it is abnormal to be easy to appear shearing,
Flying shear appears in one knife of miscut and tail portion in the normal operation of rolling often and shears too long phenomenon after breaking down, after Bar Rolling Line breaking down
The problems of flying shear is difficult to solve in existing technology, and failure often occurs repeatedly, and each failure not only results in
Averagely 30 minutes or more halt production fault times and a rolled piece roll useless, but also can be to flying shear and its phase after the Bar Rolling Line breaking down
Equipment belt is closed to damage.It follows that after Bar Rolling Line breaking down the problems of flying shear to stable and antegrade production, production cost with
And cost of equipment maintenance is brought greater impact.
Summary of the invention
1. technical problems to be solved
More, the high production cost for miscut situation existing in the prior art, the problem of plant maintenance difficulty, the present invention mention
Supplied it is a kind of prevent the control method that flying shear miscut is cut after bar breaking down, it can eliminate miscut, reduce production cost, and bar is raw
Producing line maintenance is simple.
2. technical solution
The purpose of the present invention is achieved through the following technical solutions.
A kind of to prevent the control method that flying shear miscut is cut after bar breaking down, steps are as follows:
One kind prevents flying shear after bar breaking down from missing flying shear No starting instruction production after shearing property program, including bar breaking down
Flying shear shears starting impulse instruction control unit after raw unit and bar breaking down, respectively the instruction of control output flying shear No starting and
Flying shear shears starting impulse instruction；
When bar breaking down unit end rack and bar intermediate mill head rack have steel, and flying shear does not exist after bar breaking down
When cataclasm state, the instruction of flying shear No starting generates flying shear No starting after unit issues bar breaking down and instructs after bar breaking down,
Flying shear will be unable to restart after bar breaking down, thus avoid the flying shear that miscut situation occurs；
The previous rack of flying shear has steel, the latter rack without steel after bar breaking down and flying shear is instructed without No starting
In the case of, hot metal detector is examined before the previous rack of flying shear after bar breaking down, flying shear shearing starting arteries and veins after bar breaking down

Rack (abbreviation flying shear rack) and bar intermediate mill head rack have steel, and (i.e. two rack main driving motor reality output torques are equal
Greater than 15% Rated motor torque), as have steel signal, and after bar breaking down flying shear not in cataclasm state (i.e. control list
Functional block FFWC05 output end Q is ' 1 ' state in member) when, functional block FFWC06 output end Q is ' 1 ' in the control unit, in this way,
The control unit issues the instruction of flying shear No starting, and flying shear does not start, and thus flying shear will not be made to locate always there is a situation where miscut
It is released in dead ship condition until the flying shear No starting instructs.
Starting impulse instruction control unit, the previous rack of flying shear after bar breaking down are sheared for flying shear after bar breaking down
There are steel, the latter rack without steel and in the case that flying shear is instructed without No starting, the previous rack of flying shear after bar breaking down
Preceding hot metal detector HMD6 examine (i.e. HMD6 output state becomes ' 1 ' from ' 0 ') and it is for 1 seconds more than when, the control unit
Middle functional block FFWC12 and FFWC13 output end Q will become ' 1 ' by ' 0 ', in this way, functional block FFWC14 output end in the control unit
QP will generate ' 1 ' pulse an of cycle period, thus make flying shear starting cutting head operation.
And the previous rack of flying shear has steel without steel, the latter rack after bar breaking down and flying shear is instructed without No starting
In the case where, (i.e. HMD6 output state is by ' 1 ' for hot metal detector HMD6 inspection mistake before the previous rack of flying shear after bar breaking down
Become ' 0 ') and it is for 1 seconds above when, functional block FFWC10 and FFWC13 output end Q will become ' 1 ' by ' 0 ' in the control unit,
In this way, functional block FFWC14 output end QP will generate ' 1 ' pulse an of cycle period in the control unit, thus open flying shear
Dynamic back-end crop operation.It follows that flying shear shears starting impulse after the bar breaking down when having steel in rack before and after flying shear
Instruction control unit can avoid miscut of the flying shear in the normal operation of rolling from cutting by forbidding flying shear enabled instruction.
This programme the problems of for Bar Rolling Line flying shear, based on can when having steel in rack before and after flying shear
Flying shear miscut is avoided to cut by forbidding flying shear enabled instruction, having devised a kind of prevents the control that flying shear miscut is cut after bar breaking down
Processing procedure sequence thoroughly avoids the flying shear and exists after this prevents the control method that flying shear miscut is cut after bar breaking down from coming into operation
Too long problem is sheared in one knife of miscut and tail portion in the normal operation of rolling, and practical effect is fine.
