Description
Technical field
The present invention relates to metallurgical technology field, a kind of method for aligning mild steel in particular to coil opener.
Background technology
Acid rolls production line to ensure the operation of unit continuous-stable, is generally completed at the appointed time using automatic welder
The welding of front and back two steel bands end to end.Welding machine is a kind of welding equipment of high-efficiency and precision, can quickly finish steel band Welder
Make, but higher requirement also proposed to welding material simultaneously.Welding machine needs essential information (including the thickness according to welding material
Degree, width, material, chemical composition etc.) welding parameters are adjusted, but also proposed simultaneously to the plate shape of welding material higher
Requirement.For this purpose, being aligned in the production line to the head of material and tail portion configured with coil opener before welding machine so that welding material
Material is that head, the tail portion of steel band are straight.
Coil opener is to steel band squeeze by straightening roll that it is made to change straightness.Generally there are two rows of straightening rolls, quantity
It differs, the material of different-diameter is aligned by the variation of two roller drafts.The principle of coil opener is the bending section of material
Sizable back-flexing or stretching are born in position, and the position is made to generate certain elastic-plastic deformation, after external force removes, steel warp
Elastic recovery is crossed, then reaches straight.The coil opener of the prior art is the coil opener of seven rollers, and upper roller pressure, coil opener is aligned low
The method of carbon steel is that straightener directly aligns steel band head, and the effect being straightened by steel band head judges straightener
Whether reduction settings are reasonable, need to test drafts repeatedly and just can determine that best drafts, and the setting of drafts is cumbersome, expends
Longer working hour.

Zero roll gap position；Step S104 determines the plate shape value of raw steel band；Step S106 determines No. 2 according to the plate shape value of raw steel band
The drafts of straightening roll 20, No. 4 straightening rolls 40 drafts and No. 6 straightening rolls 60 drafts；Step S108, by raw steel band
Threading enters coil opener, and according to the pressure of the drafts of No. 2 straightening rolls 20, the drafts and No. 6 straightening rolls 60 of No. 4 straightening rolls 40
Amount aligning raw steel band.
Coil opener includes two rows of straightening rolls, is 20, No. 4 straightening rolls 40 of No. 2 straightening rolls and No. 6 straightening rolls positioned at upper row
60, it is 70, No. 2 straightening rolls 20,4 of No. 1 straightening roll 50 of straightening roll 30,5 of straightening roll 10,3 and No. 7 straightening rolls positioned at lower row
The upper and lower position of number straightening roll 40 and No. 6 straightening rolls 60 is adjustable, No. 1 straightening roll 50 and 7 of straightening roll 30,5 of straightening roll 10,3
The position of number straightening roll 70 is fixed, and raw steel band is moved from the direction of No. 1 straightening roll 10 to the direction of No. 7 straightening rolls 70.First,
The zero roll gap position of No. 2 straightening rolls 20, No. 4 straightening rolls 40 and No. 6 straightening rolls 60 is calibrated, then determines the plate shape of raw steel band
Value；Drafts, No. 4 straightening rolls 40 zero of No. 2 straightening rolls 20 relative to zero roll gap position are determined according to the plate shape value of raw steel band
The drafts of the drafts of Roll-gap position and No. 6 60 zero roll gap positions of straightening roll, and according to the drafts of No. 2 straightening rolls 20, No. 4
The drafts of the drafts of straightening roll 40 and No. 6 straightening rolls 60 pressure 20, No. 4 straightening rolls 40 of No. 2 straightening rolls and No. 6 straightening rolls
60, to align raw steel band.It is docked with upstream hot rolling material process, according to the plate shape value of upstream process raw steel band to coil opener
It is adjusted, ensure that slitless connection, drafts need not be tested repeatedly, the aligning of raw steel band is efficient, and production efficiency is high.
Specifically, the method for the zero roll gap position of calibration 20, No. 4 straightening rolls 40 of No. 2 straightening rolls and No. 6 straightening rolls 60 is：
First steel wire 80 is placed between the fore side and the fore side of No. 7 straightening rolls 70 of No. 1 straightening roll 10 and is tensed, by the second steel wire
90 are placed between the transmission side and the transmission side of No. 7 straightening rolls 70 of No. 1 straightening roll 10 and tense, respectively depress No. 2 straightening rolls 20,
No. 4 straightening rolls 40 and No. 6 straightening rolls 60, if the fore side and No. 6 straightening rolls of the fore side of No. 2 straightening rolls 20, No. 4 straightening rolls 40
60 fore side touches the first steel wire 80 simultaneously, and the transmission side of the transmission side of No. 2 straightening rolls 20, No. 4 straightening rolls 40 and No. 6
The transmission side of straightening roll 60 touches the second steel wire 90 simultaneously, then 20, No. 4 straightening rolls 40 of No. 2 straightening rolls and No. 6 straightening rolls 60
Roll-gap position is labeled as zero, if fore side and transmission side both ends cannot touch the first steel wire 80 and the second steel wire 90 simultaneously,
It then needs to be adjusted the mechanical structure of straightening roll, it is level to make 20, No. 4 straightening rolls 40 of No. 2 straightening rolls and No. 6 straightening rolls 60
It is operated again after direction.
If the plate shape value of raw steel band is not more than 15I, the drafts of No. 2 straightening rolls 20 is -9mm, i.e., relative to zero roller
It is 9mm that seam position, which moves down distance, and similarly, the drafts of No. 4 straightening rolls 40 is -4mm, and the drafts of No. 6 straightening rolls 60 is
(raw material thickness of strips -1) mm；If the plate shape value of raw steel band is more than 15I, and is not more than 25I, the then pressure of No. 2 straightening rolls 20
Amount is -11mm, and the drafts of No. 4 straightening rolls 40 is -5mm, and the drafts of No. 6 straightening rolls 60 is (raw material thickness of strips -1) mm；
If the plate shape value of raw steel band is more than 25I, and is not more than 40I, then the drafts of No. 2 straightening rolls 20 is -13mm, No. 4 straightening rolls
40 drafts is -6mm, and the drafts of No. 6 straightening rolls 60 is (raw material thickness of strips -1) mm；If the plate shape value of raw steel band is big
In 40I, then the drafts of No. 2 straightening rolls 20 is -15mm, and the drafts of No. 4 straightening rolls 40 is -8mm, the pressure of No. 6 straightening rolls 60
Lower amount is (raw material thickness of strips -1) mm, and raw steel is aligned according to above-mentioned drafts so that the head of welding material, that is, steel band,
Tail portion is straight, and leveling effect is good.In actual production, slightly upwarped if final leveling effect is requirement steel plate head, tail portion
Straight as possible, the drafts small than above range 0.5 of No. 6 straightening rolls 60 of coil opener arrives 1mm.
Preferably, the diameter of the first steel wire 80 is not more than 0.5mm, and the diameter of the second steel wire 90 is not more than 0.5mm, roll gap position
Be set to zero calibration it is more accurate.
Above in association with having illustrated technical scheme of the present invention, technical solution through the invention, according to raw steel band
Plate shape value determine the drafts of No. 2 straightening rolls, No. 4 straightening rolls drafts and No. 6 straightening rolls drafts, and according to No. 2
The drafts of the drafts of straightening roll, the drafts of No. 4 straightening rolls and No. 6 straightening rolls depresses No. 2 straightening rolls, No. 4 straightening rolls and 6
Number straightening roll, to align raw steel band.It is docked with upstream hot rolling material process, according to the plate shape value pair of upstream process raw steel band
Coil opener is adjusted, and ensure that slitless connection, need not test drafts repeatedly, and the aligning of raw steel band is efficient, production
It is efficient.
