Description
Technical field
Detection technique field is the utility model is related to, especially a kind of dress of quick detection steel part net carbide tissue
Put.
Background technology
It is well known that ferrous materials are widely used among various industrial products, the wherein higher tool steel of phosphorus content
It is one of indispensable use kind, but because tool steel carbon content is higher, Technology for Heating Processing did not went out easily in matrix at that time
Now obvious net carbide tissue (as shown in Figure 2), the performance and service life of the tissue severe exacerbation material, are skills
Forbid the unqualified tissue occurred in art standard.Therefore, quickly and easily detect that the net carbide tissue in steel part aligns
Technology for Heating Processing is really formulated, improving the quality of steel part and the production efficiency of product all has highly important practical significance.
Utility model content
The purpose of this utility model is：A kind of quick detection steel part net carbide tissue device is provided, it can be quick
Whether detection steel piece surface contains net carbide tissue, and simple in construction, and cost is cheap, with overcome the deficiencies in the prior art.
What the utility model was realized in：The method of quick detection steel part net carbide tissue, comprises the following steps：
1) by one complete loop of one piece of standard specimen without net carbide tissue and magnetic circuit iron core composition, and
One group of transmitting coil and receiving coil are set respectively on magnetic circuit iron core, and being powered to transmitting coil makes it produce magnetic field, caused
Magnetic field is then passed through receiving coil by standard specimen and magnetic circuit iron core, makes to produce a corresponding induced potential in receiving coil
V0, by induced potential V0After being amplified by AC amplifier, then reading data are directly displayed from exchange gauge outfit, as marked
Quasi- potential V1；
2) sample to be tested is operated using the method for step 1), obtains measurement potential V2；
3) measurement potential V is compared2With standard electrode potential V1If measure potential V2With standard electrode potential V1It is identical, then it represents that to be tested
The detection surface of sample does not have net carbide tissue, if measurement potential V2Less than standard electrode potential V1, then the detection of sample to be tested is illustrated
Net carbide tissue be present in surface.
The device of quick detection steel part net carbide tissue, including magnetic circuit iron core, described magnetic circuit iron core are reverse U shape
Structure, transmitting coil is wound with the side of magnetic circuit iron core, transmitting coil is connected with power supply；It is wound with and connects in the opposite side of magnetic circuit iron core
Take-up circle, receiving coil are connected by AC amplifier with gauge outfit.
Described power supply is variable frequency power source.
Principle of the present utility model is：If net carbide tissue be present in sample, alternation magnetic caused by transmitting coil
By, because its net carbide tissue reduces magnetic flux to the obstruction in magnetic field, and then being produced during the sample in receiving coil
Induced potential also reduce therewith, so the induced potential V shown in gauge outfit2Again smaller than the potential V of standard specimen1。
By adopting the above-described technical solution, compared with prior art, the utility model dexterously make use of electromagnetic induction
Principle, make between magnetic circuit iron core and sample form a complete loop, using the alternating current of certain electrical potential size and frequency
Gesture makes magnetic field caused by transmitting coil, and received coil produces induced potential again after by magnetic circuit iron core and part top layer, by this
Shown after induced potential amplification with gauge outfit, by being contrasted with standard electrode potential, you can conveniently and efficiently detect containing netted
The steel part sample of carbide tissue, such mode can damage without using complicated equipment to steel part,
Production scene can be detected, and be played an important role to improve product quality and production efficiency.The utility model is simple and easy,
Cost is cheap, and using effect is good.

Accompanying drawing 2 is the net carbide tissue of steel part.
Embodiment
Embodiment of the present utility model：The method of quick detection steel part net carbide tissue, comprises the following steps：
1) by one complete loop of one piece of standard specimen without net carbide tissue and magnetic circuit iron core composition, and
One group of transmitting coil and receiving coil are set respectively on magnetic circuit iron core, and being powered to transmitting coil makes it produce magnetic field, caused
Magnetic field is then passed through receiving coil by standard specimen and magnetic circuit iron core, makes to produce a corresponding induced potential in receiving coil
V0, by induced potential V0After being amplified by AC amplifier, then reading data are directly displayed from exchange gauge outfit, as marked
Quasi- potential V1；
2) sample to be tested is operated using the method for step 1), obtains measurement potential V2；
3) measurement potential V is compared2With standard electrode potential V1If measure potential V2With standard electrode potential V1It is identical, then it represents that to be tested
The detection surface of sample does not have net carbide tissue, if measurement potential V2Less than standard electrode potential V1, then the detection of sample to be tested is illustrated
Net carbide tissue be present in surface.
