Description
Technical field
The invention belongs to slab field of measuring technique, and in particular to measurement and control in continuous casting steel billet burr removal process
Method.
Background technique
Core process of the continuous casting as steel products, has decisive role to product quality, wherein how to solve continuous casting
Slab Burr Problem is even more the key element of Improving The Quality of Products.Slab burr is exactly during slab gas flame cuttiug in bottom
The high rigidity rigidity burr of formation.Burr goes not clean, with slab can enter subsequent hot rolled process, cause to damage to roll,
The problems such as roll loses flesh occurs, shortens the service life of roll, increases considerably a ton steel spare parts cost.Simultaneously as burr master
It to be impurity component, rolling will lead to strip and the mass defects such as scab, cracks, being mingled with together with slab, greatly reduce
Strip lumber recovery.
Currently, being both at home and abroad generally removed slab burr using scraper type burr grinding machine, but ineffective, there are hairs
The problems such as thorn bonding, residual.For this purpose, there is the rotation beating type deburring machine of development at present, working principle mainly utilizes knife
The centrifugal force of piece rotation is removed the burr of slab bottom.During entire deburring, slab movement speed and position
Precise measurement it is most important.It is universal measurement mode to the mode that slab movement speed measures, that is, uses encoder pair
Electric machines for roller revolving speed measures, and then carries out mathematic(al) manipulation according to parameters such as roller diameters, is converted to the movement speed (slab of slab
It is contacted with roller-way and roller-way is relied on to be driven, so the linear velocity of roller table surface is slab movement speed).But it was actually using
It is found in journey, due to roller-way abrasion, casting blank bending etc., this kind of slab movement speed measurement method causes to cast there are error
Base deburring is incomplete.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of slab movement speed accuracy control method, realize that slab moves
The precise measurement of dynamic speed is solved the problems, such as to cause the measurement of slab movement speed inaccurate because of reasons such as roller-way roll diameter changes, be improved
The reliability of measurement data realizes the Proper Match of slab shift position and rotating blade lifting time, so that slab deburring
Rate reaches 99.99% or more.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of mobile fast slab accuracy control method of slab, is carried out, the deburring based on rotation beating type deburring machine
Machine includes at least the liftable rotary shaft of the band blade for transmitting the roller-way of slab, for removing flash removed, and each roller-way is respectively provided with
Speed measuring device tests the speed；It is characterized by: along slab moving direction, between the roller-way and rotary shaft axle center of forefront successively
At least three velocity measuring devices of interval setting；
Before reaching the third speed measuring device nearest from the roller-way of forefront on slab head, tested the speed using each roller-way
Device tests the speed mode, obtains slab speed V1；
When slab head reaches the third speed measuring device nearest from the roller-way of forefront, record reaches initial time
t1；
When slab head, which continues to move along, reaches second speed measuring device, record reaches initial time t2；And
Tachometric survey mode is first to test the speed mode by each roller-way speed measuring device pattern switching that tests the speed at this time, is tested the speed in mode first,
Slab movement speed V2It is the horizontal distance c of third speed measuring device and second speed measuring device divided by initial time t2With
Initial time t1Difference, i.e.,
When slab head continues to move along and reaches First Speed measuring device, record reaches initial time t3, this
Shi Sudu measurement method is carried out according to first mode that tests the speed, and rotary shaft is begun to ramp up at this time；It tests the speed mode in the second photoelectric tube
In, slab movement speed V3It is the horizontal distance b of second speed measuring device and First Speed measuring device divided by initial time t3
With initial time t2Difference, i.e.,If First Speed measuring device and the horizontal distance of rotary shaft axis perpendicular line are
A, the highest point of blade and the vertical distance of roller plane are d, then slab head is from First Speed measuring device is touched to most
The time of arrival rotary shaft axis perpendicular line is afterwardsWhen slab head is reached right above the axle center of rotary shaft, in order to go in time
Flash removed blade must be completely attached to slab bottom, then in order to which the retention time is consistent, surveyed when slab head reaches First Speed
Amount device arrives, and blade rotary shaft is begun to ramp up, and the rotary shaft rate of climb is
When detecting that rotary shaft reaches highest order, system starts timing rotary shaft work belt cutting blade deburring, and works as
When cumulative time reaches the setting deburring time, rotary shaft is stopped rotating and fallen to be made knots with roller plane interval, underturner
Beam, system are automatically changeb to each roller-way speed measuring device and test the speed mode.
Further, the speed measuring device of each roller-way setting is encoder；Velocity measuring device is photoelectric tube.
Further, the slab head arrival rate measuring device moment is to shelter from the photoelectric tube signal moment.
Further, three velocity measuring devices are set.
Further, annular blade is arranged in the exterior circumferential interval of rotary shaft, and along the vertical direction, the periphery of blade is knife
Piece highest point.
Further, rotary shaft uses oil cylinder lifting device.
Further, the value range of c is 20mm-50mm；Wherein the value range of b is 10mm-20mm；The value model of a
It encloses for 5mm-10mm.
Indirect speed testing mode is become direct speed testing mode by the careless mistake of the existing measurement method of improvement by the present invention as a result,
It is combined with indirect speed testing mode, economical and efficient, it is quickly accurate；
When closer from cutting point, using direct speed testing mode, third speed measuring device, second speed measurement dress are set
It sets, First Speed measuring device, signal is blocked by photoelectric tube to determine slab position, and go up and down using the signal as rotary shaft
Enabling signal, structure is simple and effective, facilitates realization；Design has multiple groups photoelectric tube in system, and utilizes first and second group of photoelectric tube
The time difference of signal triggering and distance are realized the preliminary surveying of slab movement speed, while being believed using second and third group of photoelectric tube
Number triggering time difference and distance, realize the precise measurement of slab movement speed, solve because of reasons such as roller-way roll diameter changes
The problem for causing the measurement of slab movement speed inaccurate, improves the reliability of measurement data；
Meanwhile when from cutting point farther out, using general indirect speed testing mode, reduce calculation amount, it is simple and quick；
Meanwhile it is slab is mobile and blade lifting distance realizes accurate control, by the accurate measurement of slab movement speed,
And by the reasonable conversion of the parameters such as rotary shaft and roller plane distance, when realizing slab shift position and rotating blade lifting
Between Proper Match, so that slab deburring rate is increased to 99.99% or more.
