Purpose according to the present invention is equally by according to claim 9 for continuously by the completed belt of steel making hot rolling
The method of steel is achieved.Advantageous embodiment is the theme of dependent claims.
In casting according to the present invention-rolling-equipment complex operation, the casting speed v of sheet billet slabc≥4m/
Min, preferably vc>=5m/min, particularly preferred vc≥6m/min.Therefore ensure that high productivity, and convenient for wrapping top catchmenting
It is maintained in the horizontal zone of slab guiding mechanism.In addition, reducing the energy for heating rough rolling strip steel in induction furnace.Even
The device that controls or regulates of casting machine is at least so set
Secondary cooling in slab guiding mechanism, and
Casting speed vc,
And another parameter in preferably following inventory:
First cooling in crystallizer,
Thickness in slab guiding mechanism reduces,
To the only just thoroughly solidification in the horizontal section of slab guiding mechanism of sheet billet slab.The sheet billet that thickness reduces
Slab without de-scaling-that is it not in descaling device, de-scaling-is just supplied to roughing mills, and be rolled into there thick

It is right when controlling or regulating continuous casting installation for casting it is advantageous that controlling or regulating device by means of mathematical model
The physical location on top is wrapped along the catchmenting for transport path of the sheet billet slab in the slab guiding mechanism；
With
Along the practical temperature of the transport path of the sheet billet slab in the slab guiding mechanism and its in vertical plane
It writes music line,
Carry out Continuous plus, and in view of target temperature profile and it is described catchment the target position for wrapping top in the case where,
The sheet billet slab is cooled down with being continuously regulated by the secondary cooling mechanism.Thus it catchments convenient for and wraps top guarantor
It holds in the horizontal zone of slab guiding mechanism, and prevents the sub-cooled of slab fringe region.Furthermore, it is possible to by mesh
Mark temperature curve avoids the violent cooling of the fringe region of sheet billet slab compared between actual temperature curve.
When thickness reduces advantageously, in the area of the even liquid with sheet billet slab or operative liquid core
In domain, soft reduction technique is used by the adjustment device (such as passing through slab guide section) for slab guide reel.Thus subtract
Small shape changes function, and again improves metallurgical quality.
By following manner particularly simply and high energy efficiency final rolling temperature is set: in mm finishing mill unit
The actual temperature T1 of strip is measured after third rolling pass and before the cooling in cooling sectionIt is practical, and adjusted with temperature
The mode of section manipulates multiple inductors of induction furnace, so that actual temperature T1It is practicalIt is equivalent to target temperature as far as possible
T1Target。
If alternatively measuring strip in mm finishing mill unit after the second rolling pass and before third rolling pass
Actual temperature T1*It is practical, and multiple inductors of induction furnace are manipulated in such a way that temperature is regulated, so that
Actual temperature T1*It is practicalIt is equivalent to target temperature T1* as far as possibleTarget, then accuracy can be further increased.
In order to set the tissue characteristics of finished strip, it is beneficial to, it carries out measuring continuously after cooling in cooling section
The actual temperature T2 of finished stripIt is practical, and multiple cooling nozzles of cooling section are manipulated in such a way that temperature is regulated, thus
So that actual temperature T2It is practicalIt is equivalent to target temperature T2 as far as possibleTarget。
When manufacturing relatively thin finished strip advantageously, continuous finished strip is high in casting-rolling-equipment complex
Mm finishing mill unit is left with first thickness d1 after speed operation, then in continual continuous operation step by step finished strip
Thickness is reduced to second thickness d2 < d1, and in continual continuous operation before casting-rolling-equipment complex low speed operation
In the thickness of finished strip is increased to 3 > d2 of third thickness d step by step.
Herein it is advantageous that first thickness d1 is between 3 and 12mm, second thickness d2 between 1.6 and 12mm, and
And third thickness d 3 is between 3 and 12mm.
Since the high hydrogen content in steel fusant reduces the heat dissipation in crystallizer, so it is advantageous that before continuous casting
Such as the hydrogen content of steel is reduced to≤3ppm by being vacuum-treated.
In addition, this measure to sensitive steel, such as can deep-draw steel continuous casting generate wholesome effect.

Temperature trend when the finished strip rolled.Core temperature is always shown in broken lines, and surface temperature is shown with chain-dotted line, and average temperature
Degree is shown by a solid line.The steel fusant of quality DD11 is vacuum-treated before continuous casting, thus the hydrogen in liquid steel is contained
Amount is reduced to≤1ppm.Partially solidified sheet billet slab 3 is formed in the funneling crystallizer 2 of continuous casting installation for casting 1, with a thickness of
70mm and width are 1300mm, and are deformed into the sheet billet slab 3 with a thickness of 60mm thoroughly solidified by wick-containing pressure.
The sheet billet slab 3 thoroughly solidified is with vcThe horizontal section 4c of the casting speed leaving continuous casting plant 1 of=6m/min, and without
De-scaling is just conveyed to the roughing mills 8 of two racks, and there by two roughing mills rack R1 and R2 reduce at a thickness of
The rough rolling strip steel 9 of 10mm.Pass through the phase between the output area of the second roughing mill rack R2 and the input area of induction furnace 12
To biggish distance, rough rolling strip steel 9 is cooled to about 860 DEG C of temperature.By induction furnace 12 or IH rough rolling strip steel 9 is reached
To about 1115 DEG C of temperature.Then, by descaling device 13 or DES to 9 de-scaling of rough rolling strip steel, so that under surface temperature
Drop to about 950 DEG C；In this case, core temperature is about 1020 DEG C.Then in three finishing mill machines of mm finishing mill unit 14
In frame F1, F2 and F3, the rough rolling strip steel 9 after de-scaling is rolled into the finished strip 15 with a thickness of 1.6mm, then in cooling section 16
Middle cooling, shearing, and be wound into a roll.
The thickness trend of relatively thin finished strip 15 during manufacture according to the present invention is shown in FIG. 6.It is casting
Make-roll-equipment complex high-speed cruising after, originally generate the finished strip 15 with a thickness of d1=4mm.It is cold in cooling section 16
But after, continuously finished strip 15 obtained is sheared the cutting of machine 17, and is wound into first by one of winding device 18
Volume.Then, the thickness of finished strip is reduced to d2=1.6mm from d1=4mm step by step.This by least one following measure come
It carries out:
A) thickness that device more tempestuously reduces sheet billet slab 3 is reduced by thickness in continuous casting installation for casting 1, so that this is thin
Slab slab more unfertile land leaving continuous casting plant 1；
B) thickness for more tempestuously reducing sheet billet slab 3 by roughing mills 8, so that the more unfertile land of rough rolling strip steel 9 leaves slightly
Milling train group 8；
C) thickness for more tempestuously reducing rough rolling strip steel 9 in mm finishing mill unit 14, so that the more unfertile land of finished strip 15 leaves essence
Milling train group 14.
If such as only with measure a, it will be assumed that, the reduction rate in roughing mills 8 and mm finishing mill unit 14 is kept
It is constant.Measure b and c are also applied for after this point is suitably modified.But certainly it is also possible that individual at manufacture one
Multinomial measure is used during volume.
According to Fig. 6, finished strip is after 5 volumes with the thickness of d2=1.6mm.Then kept for about 70 volumes
The thickness, and thickness is then increased to d3=3.2mm from d2=1.6mm step by step.The measure is advantageous, because on the one hand simultaneously
It is indirect that extremely thin finished strip is just generated after casting-rolling-equipment complex high-speed cruising (herein with 1.6mm
Thickness), but the equipment has longer time to want " from steady ".Only in this way just generate extremely thin finished strip.It casts-rolls
System-equipment complex operator is usually interested in generating thin hot-strip as a large amount of as possible, because he thus can be real
Existing higher profit.Before casting-rolling-equipment complex low speed operation, and increase the thickness of finished strip 15, thus in life
Produce the risk that production disruption is reduced in movable final stage.Increase finished strip thickness when, it is suitably modified after along phase
Anti- direction (less violent replacement is more violent, and thicker replacement is thinner) is at least using one of above-mentioned measure.In equipment
Continual continuous operation using whole measures, thus avoid such as because rough rolling strip steel 9 penetrates into mm finishing mill unit 14
Caused interference.Light is the stability for thus improving manufacturing process significantly.
The thickness value and volume number being presented in Fig. 6 must not restrictively understand, but simply show an example.
Although having carried out further introduction and explanation to the present invention by preferred embodiment in detail, the present invention
Therefore these disclosed examples are not limited to, and without departing from protection scope of the present invention, this field skill
