Abstract
The invention discloses a kind of methods that raw and auxiliary material impurity element to CEMENTED CARBIDE PRODUCTION carries out verification detection, for the raw and auxiliary material of CEMENTED CARBIDE PRODUCTION, the method for taking sampling calcining new process, the raw and auxiliary material of CEMENTED CARBIDE PRODUCTION is calcined by new calcine technology, then appearance determination is carried out to calcined material, so as to reduce the blindness using raw and auxiliary material, and it can quickly differentiate the quality of raw and auxiliary material.
Description
Technical field
The present invention relates to a kind of methods that raw and auxiliary material impurity element to CEMENTED CARBIDE PRODUCTION carries out verification detection.
Background technology
The raw and auxiliary material of CEMENTED CARBIDE PRODUCTION, such as sintering oxidation Al filler, the titanium dioxide with coating etc. is such as this kind of
Raw and auxiliary material impurity content exceeding index certainly will cause the surface of product pitted skin, point, pit, hole, deformation, viscous boat etc.
Defect.
Invention content
The purpose of the present invention is to provide a kind of raw and auxiliary material impurity elements to CEMENTED CARBIDE PRODUCTION to carry out verification inspection
The method of survey.The present invention adopts the following technical scheme that in order to achieve the above object：
A kind of method that raw and auxiliary material impurity element to CEMENTED CARBIDE PRODUCTION carries out verification detection, including following step
Suddenly：
The raw and auxiliary material of CEMENTED CARBIDE PRODUCTION is taken into sintering furnace vacuum calcining, and applying argon gas is protected, it is specific to calcine
Technique is：
With certain heating rate, raw and auxiliary material is heated up；
10min is kept the temperature after being warming up to 600 DEG C；
With certain heating rate, raw and auxiliary material is further heated up；
90min is kept the temperature after being warming up to 1600 DEG C；
Naturally cool to room temperature；
It comes out of the stove and observes calcined material, according to black in calcined material and the content of the impurity substances of blue, judge in raw and auxiliary material
Whether impurity content is exceeded.
Preferably, in the step 1) of calcine technology, the heating rate of raw and auxiliary material is 3 DEG C/min.
Preferably, in the step 3) of calcine technology, raw and auxiliary material further heats up speed as 8 DEG C/min.
The method that raw and auxiliary material impurity element provided by the invention to CEMENTED CARBIDE PRODUCTION carries out verification detection is directed to
The raw and auxiliary material of CEMENTED CARBIDE PRODUCTION, the method for taking sampling calcining new process, to the raw and auxiliary material of CEMENTED CARBIDE PRODUCTION
It is calcined by new calcine technology, appearance determination then is carried out to calcined material, so as to reduce the blindness using raw and auxiliary material,
And it can quickly differentiate the quality of raw and auxiliary material.
Specific embodiment
By specific embodiment, the present invention will be described in detail below, is used for herein with the illustrative examples and explanation of the present invention
Explain the present invention, but not as a limitation of the invention.
A kind of method that raw and auxiliary material impurity element to CEMENTED CARBIDE PRODUCTION carries out verification detection, including following step
Suddenly：
First, take the raw and auxiliary material (such as sintering oxidation Al filler, the titanium dioxide with coating etc.) of CEMENTED CARBIDE PRODUCTION into
Sintering furnace vacuum calcining, and applying argon gas is protected, specific calcine technology is：
1st, with certain heating rate, raw and auxiliary material is heated up；
2nd, 10min is kept the temperature after being warming up to 600 DEG C；
3rd, with certain heating rate, raw and auxiliary material is further heated up；
4th, 90min is kept the temperature after being warming up to 1600 DEG C；
5th, room temperature is naturally cooled to；
2nd, it comes out of the stove and observes calcined material, according to black in calcined material and the content of the impurity substances of blue, judge raw and auxiliary material
Whether middle impurity content is exceeded：
The appearance of calcined material is observed, the impurity substances there are many black and blue are contained after the calcining of one of which aluminium oxide,
Middle black impurity substance is larger relatively thick, blue material and the similar bulky grain of aluminium oxide；
It is the too many bad aluminium oxide of impure element to the aluminium oxide containing black or blue material, meeting after use
Product pitted skin is caused, therefore such bad aluminium oxide is also the immediate cause for causing the bad defect in the surfaces such as product pitted skin.
The technical solution provided above the embodiment of the present invention is described in detail, specific case used herein
The principle and embodiment of the embodiment of the present invention are expounded, the explanation of above example is only applicable to help to understand this
The principle of inventive embodiments；Meanwhile for those of ordinary skill in the art, embodiment according to the present invention, in specific embodiment party
There will be changes in formula and application range, in conclusion the content of the present specification should not be construed as limiting the invention.
