Abstract
The utility model relates to a magnetic measuring device, pertaining to the technical field of magnetic product tooling production. The utility model comprises an electronic balance arranged at the bottom part. A magnet is arranged on the electronic balance; a testing table made of nonmagnetic material and arranged at internal with the magnet is arranged above the magnet. With low cost, the magnetic measuring device can conveniently test the content of MnFe2O4 in the pre-sintered material and solves the problems in the prior art, such as high equipment cost and fussy measurement and operation.
Description
Technical field
The utility model relates to a kind of Magnetic Measurement device, belongs to the technical field of magnetic product production frock.
Technical background
In the manganese-zinc ferrite powder production process, pre-burning has important impact to contraction and the characteristic aspect of end article, if MnFe in the Preburning material

In the prior art, mainly weigh MnFe by the mode of measuring the Preburning material inductance
2O
4Content, aforementioned manner exists equipment cost higher, measures the problems such as operation is loaded down with trivial details.
Summary of the invention
The utility model purpose is to provide a kind of cost lower, can be easily to the MnFe in the Preburning material

4The magnetic measuring device that content detects, the equipment cost that has solved the prior art existence is higher, measures the problems such as loaded down with trivial details that operate.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises the electronic balance of bottom, is shelved with magnet on the described electronic balance, the test board that the magnet top is provided with it setting at interval and is made by no magnetic material.During test, the electronic balance reading is made zero, then get in the vessel of the no magnetic of a certain amount of specimen placement, vibrate slightly sample is shakeout, vessel are placed on the testboard in alignment with directly over the magnet again, the effect that attracts each other between magnet on the electronic balance and the specimen, thus make the reading of electronic balance become negative reading, can judge the MnFe of specimen from the reading of electronic balance
2O
4In the scope that requires, test operation is very convenient, and the cost of whole testing arrangement is also lower for content.
As preferably, described testboard is made of the leg of both sides and the platform that connects between two legs.Wherein, two legs can support platform, thereby so that keep a determining deviation between platform and the magnet.
As preferably, described test board is made by the acryl material.
Therefore, it is lower to the utlity model has cost, can be easily to the MnFe in the Preburning material
2O
4The characteristics such as content detects.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the bottom is provided with electronic balance 1, be shelved with magnet 2 on the electronic balance 1, the test board 3 that magnet 2 tops are provided with it setting at interval and are made by the acryl material, test board 3 is made of the leg 31 of both sides and the platform 32 that connects between two legs 31.
During test, as shown in Figure 1, electronic balance 1 reading is made zero, then get in the vessel 4 of the no magnetic of a certain amount of specimen placement, vibrate slightly sample is shakeout, again vessel 4 are placed on the testboard 3 in alignment with directly over the magnet 2 effect that attracts each other between the magnet 2 on the electronic balance and the specimen, thereby the reading that makes electronic balance becomes negative reading, can judge the MnFe of specimen from the reading of electronic balance
2O
4In the scope that requires, test operation is very convenient, and the cost of whole testing arrangement is also lower for content.
