Abstract
The invention discloses a method for adjusting the plate cut through a hot rolling synchronous side press. The hot rolling synchronous side press comprises a main crank mechanism and a synchronous crank mechanism. The main crank mechanism drives a die block through a mechanical connecting rod and drives a strip steel plate blank to move in the vertical direction, namely the strip steel plate blank running direction. Through utilization of the deviation of work angles of cranks on the two sides of the synchronous side press, the direction where the cranks are laterally pressed and stressed is manually controlled, and therefore the adjustment on the deviation of the horizontal direction of the hot rolling strip steel plate blank plate cut is conducted. According to the method, the side press has the plate cut adjusting function as well, the plate cut is controllable, and damage caused by collisions of the plate blank to equipment is avoided. In addition, a wedge shape is not sacrificed while the strip steel plate cut is adjusted.
Description
Technical field
The present invention relates to metallurgical industry field, it is more particularly related to utilize synchronous mode side pressure in hot rolling mill
Machine carries out the control method of roughing Profiles of Hot Rolling adjustment.
Background technology
In hot rolling mill, Profiles of Hot Rolling (shape of strip top view) problem is always that puzzlement produces is important to be asked
Topic.The impacted many factors of Profiles of Hot Rolling, the such as reason such as temperature, material, equipment state all can lead to Profiles of Hot Rolling
Off-center.
It is desirable that template control measures that can be accurate and effective for roughing, when template is subject to certain factor
When occurring deviateing, operative employee can efficiently control roughing by this means and export template.
At present, the template control technique of roughing is the adjustment to carry out template for the deviation using horizontal roller both sides roll gap,
There is no the technology carrying out template regulation and control using side compression machine.
Existing synchronous mode side compression machine synchronisation control means.
As Fig. 1, shown in 2, described synchronous mode side compression machine uses continous way fixed-width side press, continous way fixed width side
The transmission of press can be divided into three parts, has mainly been come by lateral pressing structure of shoe, Width adjusting mechanism, three mechanisms of lazy-tongs
Become.
Fig. 1 is the device structure sketch of hot rolling synchronous mode side compression machine.
Fig. 2 is the main crank of synchronous mode side compression machine, synchronization crank drives block motion schematic diagram.The motion of module
Driven respectively by main crank and synchronization crank, and order about strip in motion vertically and horizontally.In figure
In 2, main crank rotates, and moves, (module thus produces under driving mechanical connecting rod and module in the vertical direction
To the vertical direction with plate slab, i.e. the motion with plate slab traffic direction, for the motion in this direction, two
The module of side is to carry out strict mechanical synchronization action by frame for movement.And synchronization crank rotates then driving mechanical
Connecting rod and module move in the horizontal direction (module thus produces horizontal direction and moves, to plate slab perpendicular to
Strip with plate slab traffic direction laterally carries out side pressure movement), the synchronization of the horizontal direction of this both sides module is moved
Then there is no mechanical device, be completely action to be synchronized by electrical control.
(main crank and synchronization crank pair are ordered about to the angle ring of above-mentioned main crank and each autokinesis of synchronization crank
The cut-in point laterally carrying out side pressure movement perpendicular to the strip with plate slab traffic direction with plate slab sets
Put) it is defined as：It is each 45 ° in the nearest operating point of spacing module.
Can be clearly seen from Fig. 2, the angle of both sides synchronization crank determines module position during side pressure.?
During normal side pressure, the synchronization crank angle of both sides should be consistent substantially.
Existing template control technique and the problem of presence
Existing in roughing R1, the template control technique of R2 is to be entered using the deviation of roughing milling train horizontal roller both sides roll gap
The adjustment of andante type.It is embodied as：In actual motion adjustment template method, if run into template partially worked
Then working roll is pushed several MM if side, if running into the inclined transmission side of template, then several by lifting on working roll
MM.
Time that above-mentioned this method of adjustment uses longer it should say it is a kind of so far relatively effective adjustment side
Formula, its schematic diagram is as shown in Figure 3.When operating personnel have a mind to adjust both sides roll gap so that the roll gap of active side is less than
Transmission side, so, in rolling, the strip extension of active side is more, so, the plate of horizontal roller mill outlet
Type will be partial to transmission side；Similar, if operating personnel intentionally get the template of deflection active side, can
So that the roll gap regulation of active side is bigger than transmission side.
Although the regulation and control method of above-mentioned this template is effectively, also bring a problem simultaneously：Its template
Adjustment be with sacrifice carve type (because of follow-up finish rolling needs, the shape of strip sectional view needs necessarily to carve type) be front
Carry.After adjusting every time, it is carved type and all certain deviation can, when serious, also can affect the thickness of strip
Precision.
Goal of the invention
For overcoming the problems referred to above, it is an object of the invention to：
There is provided a kind of method relying on hot rolling synchronous mode side compression machine to carry out roughing control Profiles of Hot Rolling, by using same
The deviation of step formula side compression machine both sides crank operating angle, direction during manual control crank side pressure stress, come with this
Carry out the regulation of the horizontal direction deviation of Hot Strip blanket type.
See Fig. 1-8, a kind of principle of hot rolling synchronous mode side compression machine template method of adjustment of the present invention is as follows：
For synchronous mode side compression machine, the synchronization on modules dragged side pressure direction (x-axis) is mechanical synchronization, no
Method is controlled；And modules dragged synchronization in the y-axis direction is then electric synchronization.
By prior art, every time in side pressure, the angle of both sides is consistent, and that is, in the diagram, both sides module exists
Height in y-axis is consistent.So, in stress, discounting for other factors, slab is in y for slab
Should be straight on direction of principal axis (y-axis direction is slab traffic direction).
But in actual use, due to the impact of various factors (as both sides temperature deviation), the prolonging of strip both sides
Exhibition rate has certain difference, therefore, when both sides module in the synchronous case, i.e. y-axis highly consistent when,
Template has certain skewed popularity, that is, occur the inclined active side with plate slab template for the hot rolling synchronous mode side compression machine or
Transmission side problem.
Technical program of the present invention lies in purposeful, adjust strip plate typed horizontal direction (i.e. perpendicular to band with having direction
Plate slab y-axis direction) deflection.When band steel plate type in the horizontal direction (i.e. perpendicular to band plate slab y-axis direction)
When deflection, the conscious adjustment by both sides synchronization crank angle controls both sides module height on the y axis
Degree, with this to control template (i.e. perpendicular to plate slab y-axis direction) in the horizontal direction deflection.
That is, the principle of technical solution of the present invention is：
By the control of both sides synchronization crank angle, purposefully adjust (slab traffic direction two side) module and exist
The height of y-axis is so as to asymmetric, thus reaching regulation template in the horizontal direction (i.e. perpendicular to band plate slab y-axis
Direction) purpose be partial to.
A kind of technical scheme of hot rolling synchronous mode side compression machine template method of adjustment of the present invention is as follows：
A kind of hot rolling synchronous mode side compression machine template method of adjustment, is to carry out template synchronization using hot rolling synchronous mode side compression machine
Method of adjustment,
Described hot rolling synchronous mode side compression machine includes active side main crank mechanism and transmission side synchronization crank mechanism, described master
Crank mechanism orders about module by mechanical linkage, and drives plate slab in vertical direction, i.e. band plate slab operation
Move in direction,
Described synchronization crank mechanism orders about module by mechanical linkage, and drives plate slab perpendicular to vertical side
To, i.e. the transverse movement with plate slab traffic direction,
When described synchronous mode side compression machine is in holding state, main crank mechanism is with given (for example, 5 revs/min)
Speed at a slow speed is creeped, and synchronization crank mechanism is still in 0 degree,
It is characterized in that,
High-speed starting condition meets, and when bringing into operation, PLC sends high-speed starting instruction to band plate slab, main crank the
Once when 45 degree of work starting point, system sends synch command to main crank mechanism, and main crank mechanism starts
(for example, 50 revs/min) are quickly run by described even accelerating at a slow speed；
When main crank is for the second time through 45 degree of work starting point, synchronization crank mechanism starts by static even acceleration,
Until reaching the simultaneously and rapidly speed of service with main crank mechanism；
Now, as main crank mechanism and synchronization crank mechanism are not implemented synchronization to (driving) angle of module, i.e.
When leading to module highly inconsistent in the y-axis direction,
In the side pressure idle point of main crank, that is, main crank angle is [75 °, 315 °] point, to synchronization crank and main song
The differential seat angle of handle compensates,
That is, main crank speed is constant, and the synchronization crank on both sides is each given additional according to the differential seat angle with main crank
Compensate, thus control the deflection of template (i.e. perpendicular to plate slab y-axis direction) in the horizontal direction.
This is because, at this moment, both achieve Y-direction at (main crank mechanism and synchronization crank mechanism are to module)
Speed sync, but both driving angles of (main crank mechanism and synchronization crank mechanism are to module) are also not carried out
Synchronous, i.e. because angle is also not carried out synchronization, height is also inconsistent in the y-axis direction to lead to module.
In this regard, the differential seat angle of main crank and synchronization crank (must not be worked in the side pressure idle node of each cycle
Point), namely main crank angle be [75 °, 315 °] in the range of be compensated,
As a result, active side synchronization crank is in side pressure, can be than transmission side synchronization angleFast A angle,
So that active side module A angle faster than transmission side module on the y axis.
In this way so that active side synchronization crank is in side pressure, can be than the fast A angle of transmission side synchronization angle
Degree, so that active side module A angle faster than transmission side module on the y axis.Set up by above synchronization and control
Method, the result finally drawing is that both sides synchronization crank angle is consistent, eliminates template deviation so that side compression machine also has
The function of template adjustment.

/ point speed at a slow speed creep.
According to a kind of hot rolling synchronous mode side compression machine template method of adjustment of the present invention,
High-speed starting condition meets, and when bringing into operation, PLC sends high-speed starting instruction to band plate slab, main crank the
Once when 45 degree of work starting point, system sends synch command to main crank mechanism, and main crank mechanism starts
By described even at a slow speed accelerate to, for example, 40-80 rev/min of quick operation.
According to a kind of hot rolling synchronous mode side compression machine template method of adjustment of the present invention,
Described compensation way is：
Main crank speed is constant, and the synchronization crank on both sides each provides the benefit of 5-10% according to the differential seat angle with main crank
Repay.

KOcomFor active side main crank synchroballistic angle,
KDcomFor transmission side synchronization crank synchroballistic angle,
Based on degree in crank angle,
For active side synchronization crank angle,
For transmission side synchronization crank angle,
K is coefficient, 0.7-0.9.
In (Fig. 8) KOcomIn, the differential seat angle of original main crank and this side synchronization crank is added to be needed to adjust
Angle, this angle A sends PLC to after being inputted on operation screen by operating personnel.Original KDcomKeep
Constant.I.e.：
In formula,Based on degree in crank angle,For active side synchronization crank angle,Synchronous for transmission side
Degree in crank angle, KDcom, KOcomRepresent coefficient, 0.7-0.9.
So, in the range of main crank angle is for [75 °, 315 °], active side synchronization crankTarget angle
Degree is no longer main crank angle, butAngle；And the angle on target of synchronous side synchronization crank is still main
Degree in crank angle.
