Description
Technical field
The present invention relates to the methods for bearing slab (containing a slab) during continuously casting.
Background technique
Since the 1960s, electromagnetism roller is widely used in always steel-making industry.In fact, electromagnetism roller be used to keep
Molten steel is stirred to increase the internal soundness of slab.
Currently, the slab that people's production is increasingly thicker, so as to cause longer metallurgical length.This to make under meniscus
The potential site of electricity consumption magnetic roller is lower.
Simultaneously as slab becomes more and more wider to the needs of higher productivity and further types of application.Aforementioned two
Kind slab Production trend itself proposes great challenge to electromagnetism roller.In fact, electromagnetism roller is under the action of ferrostatic pressure
It cannot bear too big mechanical flexure.
In general, steel-making producer receives very small mechanical flexure only to guarantee the zero defect production of slab.The height of slab is scratched
Song does not only result in face crack and underbead crack, but also the stability in molten steel pond may be influenced because of bulking effect.
This expansion behavior interferes steel meniscus and powder is caused to retain, to significantly affect the quality of steel grade.It is this
Effect will appear in the case where roller is far from meniscus.
Therefore, in this casting machine, it is necessary to so that the design of electromagnetism roller is guaranteed that the mechanical flexure of slab is minimum, any
In the case of all cannot be greater than machine builder setting limiting value.
The theory of beam teaches that flexure is determined by the mechanical dimension and performance of load-up condition and electromagnetism roller；It carries
Lotus condition refers to the position that the type of load and load are distributed on beam.
Problem, which is how mechanically to design to bend with the smallest possible, bears ferrostatic pressure as big as possible
Electromagnetism roller, while the diameter for keeping roller firmly in mind keeps suitable with the diameter of adjacent roller.Other than these Considerations, electromagnetic performance
It must keep the higher benefit thinking slab and bringing on metallurgy.
In general, load is symmetrically distributed on slab.In certain position in casting machine on the lower, for certain thickness and width
Slab, for conventional single type roller, ferrostatic pressure may be high so that the flexure of roller too greatly without being able to satisfy machine
The needs of manufacturer.
In fact, in order to limit the flexure of roller, it is known that and be used for three kinds and possible solution, but every kind of solution
Scheme all has the shortcomings that specific.
The first known solution is the diameter of increase electromagnetism roller to increase the resistance area of roller cross section.This is resonable
It is usually infeasible by being above feasible, but in practice, this is because the diameter of electromagnetism roller should with adjacent roller and this
The nip rolls holding of section is mutually coordinated.Therefore, this may expansion behavior to slab and cracking rate have an impact.
Length of the solution known to second based on roller, because the length of roller plays a major role in flexure.For
Width is greater than the slab of 2500mm, and electromagnetism roller can be divided into two has the rollers of half length to control mechanical flexure,
Guarantee the electromagnetic force of the higher level on molten steel simultaneously.
This solution based on fraction electromagnetism roller is described in patent US2015/0290703, and this
Kind solution has used the several years in the industrial production.However, that is, slab is shorter than if the length of roller becomes too short
2500mm, due to the length of the half of electromagnetism roller, electromagnetic force be not enough to effectively stir molten steel and improve slab inside it is intact
Property.
It is and the pole span of electromagnetism roller and electromagnetism roller because electromagnetic force is proportional to the pole span of electromagnetism roller that this thing happens
Length is related.Therefore the length of electromagnetism roller is shorter, and electromagnetic force is weaker.
The third known solution is known as the embodiment of support roller.Instead of roller is converted into two cylinders,
And a backing roll is installed among electromagnetism roller to support electromagnetism roller.This idea is very attractive, but this simple solution
Certainly scheme shows larger disadvantage in industrial practice.
Under industrial process conditions, due to various sizes of particle or object, --- such as mill scale --- is introduced in electromagnetism
Between roller and support roller, thus it is unable to ensure close and good contact at all.Therefore, both electromagnetism roller and support roller have
The sign of accelerated wear test is all damaged in many cases.
Using this solution, the service life of electromagnetism roller and support roller is greatly shortened, so as to cause maintenance cost mistake
It is high.Thus the solution does not have industrial reliability.
Therefore, it is necessary to for for continuous casting machine bear slab method and apparatus carry out it is perfect, so as to gram
At least one disadvantage in the shortcomings that taking the prior art.
It is an object of the present invention to provide a kind of method for bearing slab for continuous casting machine, this method allows
The lateral delfection of slab is limited, even if in receiving region of the slab by significant ferrostatic pressure, it also can be in this way, simultaneously really
The necessary electromagnetic force that can guarantee the high efficiency being stirred to the core of slab or the liquid metal of inside is protected.
It is a further object of the present invention to provide a kind of method for bearing slab during continuously casting, this method allows
The diameter of the diameter for ensuring electromagnetism roller and adjacent roller is mutually coordinated, consequently facilitating electromagnetism roller is in the section for being located at Casting Equipment downstream
In combination.
It is a further object of the present invention to provide a kind of methods for bearing slab during continuously casting, wherein molten steel
On electromagnetic stirring force along width of plate slab more evenly, so as to cause better metallurgical effect.
Applicant has designed, has tested and implemented the present invention, thus the shortcomings that overcoming the prior art and obtain hereafter
The advantages of illustrating.
