Abstract
The utility model relates to an electromagnetic stirring device of a continuous casting machine, in particular to a supporting structure of a slab secondary cooling zone electromagnetic stirring roller. The supporting structure comprises an electromagnetic stirring roller and brackets arranged at two ends of the electromagnetic stirring roller, and is characterized in that the middle part of the electromagnetic stirring roller with small diameter and long roller surface is provided with a supporting device which is used for improving the strength of the electromagnetic stirring roller, wherein the electromagnetic stirring roller and the supporting device are in rolling contact. The supporting structure reduces the static pressure of molten steel generated by the electromagnetic stirring roller, and improves the stress condition of the electromagnetic stirring roller, so as to meet the demand for mechanical strength under the circumstances without increasing the diameter of the stirring roller or breaking the stirring roller. The supporting structure not only can keep the prior diameter of the electromagnetic stirring roller unchanged, but also can reduce the wall thickness of the stirring roller by 20 to 30 percent at the same time. The reduction of the wall thickness is more beneficial to magnetic field penetration, and tests prove that the magnetic field intensity of a working surface is increased by 20 percent, and the maximum bending stress of the stirring roller is decreased by 50 percent than before. Therefore, the supporting structure has obvious effects.
Description
Technical field
The utility model relates to the electromagnetic mixing apparatus of conticaster, refers in particular to a kind of supporting construction of slab two cold-zone electromagnetic agitation rollers.
Background technology
Slab two cold-zone electromagnetic agitation adopt following three kinds of forms usually: travelling-magnetic-field type, roll-type travelling-magnetic-field type (electromagnetic agitation roller) and magnetic pole plug-in type travelling-magnetic-field type behind the roller.Wherein electromagnetic agitation roller profile is similar to common backing roll, can be installed in very easily on the slab caster and does not change the structure of conticaster, thereby be widely used.But it is, therefore not enough for long its mechanical strength of electromagnetic agitation roller of roll surface above 2000mm because the electromagnetic agitation roller diameter must similarly to common backing roll generally be not more than 250mm.Prior art is exactly to strengthen the diameter of electromagnetic agitation roller or the electromagnetic agitation roller is made 2 merogenesis.Dilated diameter will inevitably change the structure of conticaster and make 2 merogenesis the magnetic circuit section is opened, and electromagnetic force is reduced greatly.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of agitating roller diameter that neither strengthens is provided, and again not with its disjunction, and can effectively improve the supporting construction of the slab two cold-zone electromagnetic agitation rollers of its mechanical strength.
The technical solution of the utility model is a kind of electromagnetic agitation roller supporting construction that comprises the electromagnetic agitation roller and be arranged on the support at electromagnetic agitation roller two ends of structure, be characterized in: the middle part of the electromagnetic agitation roller of small diameter long roll surface is provided with bracing or strutting arrangement, be used to improve the intensity of electromagnetic agitation roller, wherein adopt the rolling contact structures between electromagnetic agitation roller and the bracing or strutting arrangement.
Advantage of the present utility model and result of use:
The increase that the utility model supports can significantly reduce the suffered ferrostatic pressure of electromagnetic agitation roller, improve the stressing conditions of electromagnetic agitation roller greatly, thereby can not satisfy requirement of mechanical strength under the situation with its disjunction again neither increasing the agitating roller diameter, make the electromagnetic agitation roller have great development space.The utility model not only can keep the diameter of original electromagnetic agitation roller constant, the wall thickness of agitating roller can also be subtracted book 20%-30% simultaneously.The book that subtracts of wall thickness is more conducive to penetrating of magnetic field, and after tested, the working face magnetic field intensity has increased by 20%, and the maximum stress in bend of agitating roller reduces 50% than original, and effect is quite obvious.Keeping and the increase of mixing power of agitating roller diameter makes the electromagnetic agitation roller become neither to change existing stereotype plate billet continuous casting machine structure and can directly install to have unique a kind of slab electromagnetic mixing apparatus that mixing power is big, metallurgical effect is good simultaneously again.Become the direction of slab two cold-zone magnetic stirrer development.

The specific embodiment
By Fig. 1,2 as can be known, the utility model is made up of electromagnetic agitation roller 4 and the support that is arranged on electromagnetic agitation roller 4 two ends, be characterized in: the middle part of the electromagnetic agitation roller 4 of small diameter long roll surface is provided with bracing or strutting arrangement 5, be used to improve the intensity of electromagnetic agitation roller 4, wherein adopt the rolling contact structures between electromagnetic agitation roller 4 and the bracing or strutting arrangement 5.
The bracing or strutting arrangement 5 that is arranged on electromagnetic agitation roller 4 middle parts described in the utility model comprises left backing roll 2 and right backing roll 3, and wherein left and right sides backing roll is arranged side by side below electromagnetic agitation roller 4.Described bracing or strutting arrangement 5 also comprises support 1, and wherein left backing roll 2 and right backing roll 3 are arranged on the support 1 by bearing and roll shaft.
Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; do not breaking away under the preceding topic of the utility model design philosophy; engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
