Abstract
The utility model provides an opening type magnetic stirrer for nozzle swirl. The opening type magnetic stirrer comprises iron cores, coils and a housing, wherein a plurality of iron cores are fixed inside the housing, the coils are wound on the iron core and are in annular arrangement, and current magnitude and phase angle can be adjusted separately. Magnitude and direction of the electromagnetic force can be controlled by controlling the current and phase angle of each coil set, thereby realizing electromagnetic stirring of molten metal in a nozzle. The magnetic stirrer is of an opening type and free in use and installation during production process. In addition, the magnetic stirrer is simple in structure and easy for installation, and has promising prospect for industrial application.
Description
Technical field
The utility model relates to a kind of continuous casting of metal mouth of a river agitator, particularly a kind of open type mouth of a river eddy flow magnetic stirrer.
Background technology
In continuous casting of metal technology, liquid metal enters tundish by the mouth of a river from big bag, enter crystallizer by submersed nozzle from tundish again, the mouth of a river goes out the flow regime that stream mode can influence liquid metal in the crystallizer, the temperature field, liquid fluctuating etc., and then directly have influence on the quality of strand.Up to now, in existing continuous casting of metal technology, the through type mouths of a river of adopting more, mouth of a river section does not add stirring, the degree of depth that impacts is big, and field trash is difficult to come-up, and setting rate is low, defectives such as liquid level slag concurrent heating deficiency, for this reason, Japan etc. have developed the mechanical type eddy flow downspout, namely put into rotary blade in the mouth of a river, produce when liquid metal is flow through and rotatablely move, but this kind method, the liquid metal field trash causes nozzle blocking because sticking on the impeller, and liquid metal is to impeller seriously corroded etc., and the difficulty of installation is arranged, and impeller is changed defectives such as inconvenience.Therefore, application prospect is very limited.
The utility model content
At the defective that prior art exists, the purpose of this utility model provides a kind of open type mouth of a river eddy flow magnetic stirrer.Can be used for liquid metal continous casting sprue electromagnetic agitation, can change the flow regime of liquid metal in the mouth of a river, contactless with liquid metal, there is not corrosion, do not pollute liquid metal, and simple in structure, be easy to install, easy to operate.
For achieving the above object, the utility model adopts following technical scheme:
A kind of open type mouth of a river eddy flow magnetic stirrer comprises iron core, coil, shell and yoke plate; Some described iron cores are fixed on enclosure, and described coil is wrapped on the iron core, and circular array and size of current and phase angle can be regulated respectively.Described yoke plate is located on the shell.
Above-mentioned shell is " U " shape or open circles annular or non-enclosed polygon.
Above-mentioned shell is provided with cooling water intake and cooling water outlet.
Above-mentioned shell is nonferromugnetic material.
Lay the mouth of a river in the opening of above-mentioned shell.
There is liquid metal to pass through in the above-mentioned mouth of a river.
The utility model operation principle: the size and Orientation that size and the phase angle by electric current in the control coil can change electromagnetic force, in opening, form a rotating excitation field, drive liquid metal and flow, thereby change the state in flow field in the liquid metal.
The utility model has following apparent substantive distinguishing features and advantage compared with prior art:
The utility model can solve the deficiencies in the prior art, changes the size and Orientation of electromagnetic force by the size and Orientation that changes agitator interior loop electric current, and what drive liquid metal in the mouth of a river flows the eddy flow of liquid metal in the formation mouth of a river.Freely dismantling when shell can make things convenient for agitator to use at the mouth of a river for the open type shell removes, and do not influence the use at the mouth of a river.Simple in structure, easy for installation, prospects for commercial application is extensive.
