Abstract
The invention discloses a method for verifying and detecting impurity elements in raw and auxiliary materials used for production of a hard alloy. A novel sampling and calcining process is employed directed at the raw and auxiliary materials used for production of the hard alloy; the raw and auxiliary materials used for production of the hard alloy are calcined by using the novel calcining process; then the appearance of calcined substances is determined; thus, blindness in usage of raw and auxiliary materials is mitigated, and the quality of the raw and auxiliary materials can be rapidly discriminated.
Description
Technical field
The present invention relates to a kind of raw and auxiliary material impurity element to CEMENTED CARBIDE PRODUCTION to carry out verifying the method detected.
Background technology
The raw and auxiliary material of CEMENTED CARBIDE PRODUCTION, as sintering oxidation Al filler, titanium dioxide of joining coating etc., as this kind of raw and auxiliary material impurity content exceeding index, certainly will cause the defect of pitted skin, pit, pit, hole, distortion, sticky boat etc. to the surface of product.
Summary of the invention
A kind of raw and auxiliary material impurity element to CEMENTED CARBIDE PRODUCTION is the object of the present invention is to provide to carry out verifying the method detected.The present invention adopts following technical scheme in order to achieve the above object:
Carry out the raw and auxiliary material impurity element of CEMENTED CARBIDE PRODUCTION verifying the method detected, comprise the following steps:
The raw and auxiliary material getting CEMENTED CARBIDE PRODUCTION enters sintering furnace vacuum calcining, and applying argon gas is protected, and concrete calcine technology is:
With certain programming rate, raw and auxiliary material is heated up;
10min is incubated after being warming up to 600 DEG C;
With certain programming rate, raw and auxiliary material is heated up further;
90min is incubated after being warming up to 1600 DEG C;
Naturally cool to normal temperature;
To come out of the stove observation calcined material, according to the content of black in calcined material and blue impurity substances, judge in raw and auxiliary material, whether impurity content exceeds standard.
Preferably, the step 1 of calcine technology) in, the programming rate of raw and auxiliary material is 3 DEG C/min.
Preferably, the step 3 of calcine technology) in, the further programming rate of raw and auxiliary material is 8 DEG C/min.
Raw and auxiliary material impurity element to CEMENTED CARBIDE PRODUCTION provided by the invention carries out verifying the raw and auxiliary material of the method for detection for CEMENTED CARBIDE PRODUCTION, take the method sampling calcining new technology, the raw and auxiliary material of CEMENTED CARBIDE PRODUCTION is calcined by new calcine technology, then appearance determination is carried out to calcined material, thus reduce the blindness using raw and auxiliary material, and the quality of raw and auxiliary material can be differentiated fast.
Embodiment
Describe specific embodiment in detail the present invention below, be used for explaining the present invention with illustrative examples of the present invention and explanation at this, but not as a limitation of the invention.
Carry out the raw and auxiliary material impurity element of CEMENTED CARBIDE PRODUCTION verifying the method detected, comprise the following steps:
One, the raw and auxiliary material (as sintering oxidation Al filler, joining the titanium dioxide etc. of coating) getting CEMENTED CARBIDE PRODUCTION enters sintering furnace vacuum calcining, and applying argon gas is protected, and concrete calcine technology is:
1, with certain programming rate, raw and auxiliary material is heated up;
2,10min is incubated after being warming up to 600 DEG C;
3, with certain programming rate, raw and auxiliary material is heated up further;
4,90min is incubated after being warming up to 1600 DEG C;
5, normal temperature is naturally cooled to;
Two, to come out of the stove observation calcined material, according to the content of black in calcined material and blue impurity substances, judge in raw and auxiliary material, whether impurity content exceeds standard:
Observe the outward appearance of calcined material, wherein contain much black and blue impurity substances after a kind of aluminium oxide calcining, wherein black impurity material is comparatively large comparatively thick, blue material and the similar bulky grain of aluminium oxide;
To the aluminium oxide containing black or blue material, be the too many bad aluminium oxide of impure element, can cause product pitted skin after using, therefore this type of bad aluminium oxide is also the immediate cause causing the surperficial bad defects such as product pitted skin.
Above the technical scheme that the embodiment of the present invention provides is described in detail, apply specific case herein to set forth the principle of the embodiment of the present invention and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the embodiment of the present invention; Meanwhile, for one of ordinary skill in the art, according to the embodiment of the present invention, embodiment and range of application all will change, and in sum, this description should not be construed as limitation of the present invention.
