Abstract
The invention relates to a straightening method of a steel plate of a container containing nickel and vanadium, which correspondingly determines and controls the recording temperature and the roll bending form according to the actual nominal thickness and nominal width of the steel plate and the recording thickness input into a straightening model, and carries out three times of straightening operation. The method has the advantages of reasonable process selection, scientific parameter determination and accurate control mode, improves the qualification rate of the nickel-vanadium-component-containing container steel plate from the original 80% to 97% after the implementation, and advances the whole delivery date by more than 10 days, thereby not only improving the comprehensive yield of the nickel-vanadium-component-containing hot rolled container steel plate, but also reducing the plate shape straightening rate; but also obviously reduces the waste loss caused by unqualified plate shapes.
Description
Technical field
The invention belongs to the steel rolling field, relate in particular to a kind of plate shape method for aligning that is used to contain the hot rolling tank plate of nickel vanadium composition steel.
Background technology
The hot rolling tank plate that contains nickel vanadium composition is a kind of low-alloy steel plate for container that just occurred in recent years.Because this steel plate width is bigger, from 2000mm until more than the 3000mm; And the thickness span is big, does not wait to 32mm thickness from 12mm.This steel plate is its serviceability of assurance in the operation of rolling in addition, a series of controlled rolling measures and Constraint Cooling Technology have been taked, therefore make the steel-plate shape deformation rate after rolling bigger, and very be difficult to aligning, and the plate shape qualification rate behind the aligning has only about 80%, causes the steel plate of this kind can't guarantee whole delivery date, and caused more waste product because of plate shape is defective, both influence the prestige of steel rolling mill, wasted the energy again, caused unnecessary economic loss.
By retrieval, Shang Weijian is about the document record and the document announcement of the hot rolling tank plate aligning that contains nickel vanadium composition.
Summary of the invention
Purpose of the present invention is exactly at the problems referred to above, provides a kind of technology simple, and Rational Parameters is convenient to control and grasp, can increase substantially the straightening operation method that contains nickel vanadium composition tank plate of plate shape qualification rate.
For this reason, the technical solution that the present invention taked is:
A kind of method for aligning that contains nickel vanadium composition tank plate, be according to actual nominal thickness of steel plate and nominal width, press the typing thickness of the corresponding given and input aligning model of class, correspondingly determine and control typing temperature and roller form, carry out three passage straightening operations.
Its concrete straightening process and parameter are:
1, by real stepping:, steel plate is carried out stepping according to actual nominal thickness of steel plate and nominal width.
2, by the table typing: by class correspondence following " contain nickel vanadium composition tank plate aligning parameter list ", determine and import typing thickness and typing temperature, and strictness is controlled to computer.
Contain nickel vanadium composition tank plate aligning parameter list
3, transfer roller by shape:, take corresponding roller system according to steel plate deformed position and shape:
Steel plate center shape wave adopts-0.8～-2.2 negative roller;
Steel plate kink shape is adopted+1.2～+ 2.5 positive rollers;
The steel plate less roller adjustment of wooden dipper Qu Caiyong end to end, the roller scope is between-0.8～+ 0.8.
4, every block plate is aligned three passages.
Beneficial effect of the present invention is:
Because process choice of the present invention is reasonable, parameter is determined science, control mode accurately puts in place, therefore make the hot rolling tank plate plate shape qualification rate that contains nickel vanadium composition bring up to 97% level after implementing by original 80%, whole delivery date is in advance more than 10 days, not only greatly improved the finished product rate that contains nickel vanadium composition hot rolling tank plate, reduced plate shape and returned strong rate; And obviously reduced tank plate because of the defective loss due to spoiled work that causes of plate shape, and user's satisfaction is significantly promoted, can create 1,500,000 yuan of economic benefits every year.Simultaneously, the inventive method is simple, grasps easily, and is short and sweet, is convenient to control.
The specific embodiment
Below, in conjunction with the embodiments the present invention is further described.
Find that by production practices and result of study for the hot rolling tank plate that contains nickel vanadium composition, thickness is thin more, and then to roll the deflection of back steel plate big more; And thin steel plate, even thickness is identical, but because the width difference, its deformation rate also is not quite similar; Therefore and the wide more deflection of steel plate is big more, and institute's given straightening force that requires is also just big more.The process of steel plate aligning is exactly to eliminate the internal stress of steel plate by the elastic-plastic deformation that constantly replaces, thereby reaches the effect of smooth aligning.For this reason, tank plate method for aligning of the present invention, according to actual nominal thickness of steel plate and nominal width, steel plate is pressed actual (real) thickness, be divided into 6 nominal thicknesses, corresponding each thickness is divided into 14 class with developed width, by class predefined typing thickness is imported computer aligning model respectively, corresponding definite and input typing temperature, and according to steel plate deformed position and shape, adjust corresponding positive roller or negative roller form, carry out three passage straightening operations, and finally align out the steel plate of on-gauge plate shape.
The foundation that its corresponding concrete technological parameter is selected and scope are shown in " containing nickel vanadium composition tank plate aligning parameter list ".
In the table: nominal thickness and nominal width are represented the actual (real) thickness of steel plate respectively;
Typing thickness and typing temperature are then represented thickness and the temperature to the input of computer aligning model respectively.
