Description
Technical field
A kind of proving installation of carbon anode resistivity relates to a kind of carbon anode determination of resistivity test electrode that is used for.
Background technology
In the plain production run of charcoal, carbon anode resistivity is to detect an important indicator of carbonaceous product.It directly affects the energy resource consumption of aluminium production and other performance of product.
At present, measuring the carbon material resistivity method is that the surface of adopting conducting probe to touch sample is come, and obtains the voltage drop between two sections, measures.Because the singularity of carbon material generally need be surveyed 3-4 time equably along the cylinder of right cylinder sample, every mensuration once needs to revolve and turn 90 degrees or 120 spend; Because probe and sample surfaces contact pressure change and cause measuring error, accuracy of measurement is reduced, reappearance is relatively poor, and often test result is only represented the average voltage drop of its test point, can not represent the average voltage drop of two parallel cuts fully.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, and a kind of proving installation of carbon anode resistivity of energy Validity Test sample two parallel cut average voltage drop is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of proving installation of carbon anode resistivity is characterized in that this apparatus structure comprises:
Test electrode stationary fixture-this geometrical clamp is the pincer insulation anchor clamps one that made by insulating material, that the termination is ring-like column when closed, anchor clamps are made up of fixed pin, fixing semi-circular column jaw and the pincers handle of support spring two symmetries, run through anchor clamps and be provided with binding post on insulation anchor clamps jaw;
Test electrode-this test electrode is four semi-circular strip shaped electric poles, divides two groups parallelly respectively to establish the portion of both sides up and down that projection is embedded in semi-circular column jaw inner ring surface, and the afterbody of electroplax connects with the binding post that passes insulation stationary fixture jaw.
Device of the present utility model utilizes two groups of semi-circular copper test electrodes, and two arrays of electrodes is insulated from each other, and guarantees to contact the sample circumference simultaneously, firmly evenly, full contact, accurate positioning is measured and once finished, and is simple to operation.Avoid rotating the change of equipotential surface in the sample in the mensuration process, guarantee the depth of parallelism of test two sections and the uniformity coefficient of sampling, maximization obtains the average voltage drop of two parallel cuts, guarantees the authenticity of value.Make the mensuration of resistivity more accurately true.

Embodiment
A kind of proving installation of carbon anode resistivity, this apparatus structure comprises: test electrode stationary fixture-this geometrical clamp is the pincer insulation anchor clamps one that made by insulating material, that the termination is ring-like column when closed, anchor clamps are made up of 4 fixed pin 1, support spring 2 fixing semi-circular column jaw 3 and pincers two symmetries, run through anchor clamps and be provided with binding post 5 on insulation anchor clamps jaw; This test electrode of test electrode 6-is four semi-circular strip shaped electric poles, divides two groups parallelly respectively to establish the portion of both sides up and down that projection is embedded in semi-circular column jaw inner ring surface, and the afterbody of electroplax connects with the binding post that passes insulation stationary fixture jaw.7 is view window among the figure.
The Insulation test anchor clamps are by injection mold injection moulding one-shot forming, are divided into two parts, in each part four anchor points are set respectively, guarantee that two parts fit like a glove, and can not misplace.The handle place connects with rivet, is equipped with appropriate spring, makes anchor clamps can evenly apply the power of 0.5 ~ 1.0kg.
In two parts anchor clamps middle inside spacing being arranged respectively is the 8mm semi-circular recesses that is 50mm, wide, so that damascene copper test electrode, the test electrode internal diameter that assembles is 50mm, circle segment is not less than 2/3 of circumference, and be not more than 200um with the specimen surface of contact, four copper test electrodes are divided into positive and negative two polarity, and two test electrodes of same equipotential surface are a polarity, also draw test mV value thus with reliable connection of copper conductor respectively.
After the sample carbon rod places, test fixture is sandwiched in sample middle part, and movable two parts make it meshing fully, make the test electrode annulus fully contact sample surfaces, after the sample two ends passed to steady current, detected pressure drop was the mean value of this sample two sections electric potential difference.
