Description
Technical field
The utility model belongs to the electromagnetic agitation intensity field of measuring technique, particularly relates to a kind of test unit that the crystallizer electromagnetic agitation intensity is used of measuring.
Background technology
Electromagnetic agitation is that continuous casting technology improves the strand shrinkage cavity, reduce center segregation, improve the important procedure of strand degree of purity, behind the crystallizer electromagnetic agitation long service, the decay of electromagnetism intensity is inevitable, smelter relies on mostly and reprocesses the answer electromagnetism intensity at present, detect the important survey instrument of the gaussmeter of electromagnetism intensity as online magnetic test coil performance and examination, but because the magnetic induction density difference of each point in the crystallization copper pipe, excessive too small magnetic induction density all can bring adverse influence to slab quality, gaussmeter need could accurately be measured the magnetic induction size of each point by certain aid, do not measure the magnetic induction density of each point in the copper pipe owing to there is special-purpose aid, general just the employing is bundled in gaussmeter on the pole, can only generally measure the magnetic induction density of coil with this form, the data precision that obtains is not high, therefore, develop and a kind ofly can accurately measure the test unit that the crystallizer electromagnetic agitation intensity is used, become one of urgent problem in the continuous casting technology.
Summary of the invention
The test unit that the purpose of this utility model is to provide a kind of measurement crystallizer electromagnetic agitation intensity simple in structure, easy to use, that be convenient to measure each position magnetic induction density in the copper pipe to use.
The purpose of this utility model is to adopt following technical solution to realize: it comprises radially scaleplate, vertical graduated tube and sleeve, it is characterized in that described radially scaleplate fixedlys connected with sleeve, the pore diameter of described sleeve pipe is greater than the external diameter of vertical graduated tube, described vertical graduated tube can match with the pore top of sleeve pipe, be provided with through hole in this vertical graduated tube, this through hole communicates with the pore of sleeve pipe.
Because the utility model adopts radially scaleplate to fixedly connected with sleeve, the pore diameter of sleeve pipe is greater than the external diameter of vertical graduated tube, vertically match with the pore top of sleeve pipe in the lower end of graduated tube, vertically be provided with through hole in the graduated tube, and the structure that through hole communicates with the pore of sleeve pipe, gaussmeter was fixedly connected on lower cartridge when it used, then sleeve is placed on the stirrer center position, make the gaussmeter measurement point be adjusted at the stirrer central point, at this moment change the power frequency of stirrer, can measure the magnetic induction intensity under the different parameters condition, it has easy to operate, can be quick, accurate measuring center point magnetic induction intensity and frequency, the rule that electric current changes, therefore, it is the test unit that a kind of comparatively ideal measurement crystallizer electromagnetic agitation intensity is used.
