Embodiment 1
[0026]Get standard comparison table for corrected high temperature carbonization furnace temperature:
[0027]1) Tungsten powder (200 kg) was added to carbon black (13.15 kg) for 6 hours in the plow mixer, and the W + C mixture was obtained.
[0028]2) The above W + C mixture, according to 10 g, press the standard block of 6.5 mm * 5.25mm * 20 mm, co-pressed 120 pieces of standard blocks, the physical map of the standard blockimage 3Indicated. The remaining W + C mixture is vacuum isolation.
[0029]3) Heat the carbonization furnace to 1900 ° C, add a standard block, carbonization 2h, take out the standard block, measure the size of the standard block after carbonization, then calculate the shrinkage ratio of the standard block according to the measured size, resulting in 1900 ° C, Standard block shrinkage;
[0030]4) According to the method of step 3), the shrinkage of the standard block is calculated from 1901 to 2019 ° C, and the temperature is warmed at the rate of 1 ° C / segment, and the ...

[0034]A particle size distribution range is selected from 0.935, and the powder Fei's particle size is 3.06 μm.
[0035]Tungsten powder (200 kg) was added to carbon black (13.15 kg) for 6 hours in the plow mixer, and W + C mixture was obtained.
[0036]The above W + C mixture is pressed into a standard temperature bump 6.5mm * 5.25mm * 20mm, placed in a high temperature carbonifier (small repair) and product (remaining W + C mixture) with the furnace 2h, optical infrared temperature The instrument displays a carbonization temperature of 2000 ° C.
[0037]The standard measuring block after carbonization was measured high, width, and the length size was 5.330 mm, 4.305 mm, 16.400mm, and the compression rate was 18%, and the current carbonization temperature was 2000 ° C, respectively. Described that the current surface display carbonization temperature is consistent with the calibration temperature, and the performance of the high-temperature carbonization furnace has not changed, and the equi...

[0040]A particle size distribution range is selected from 0.935, and the powder Fei's particle size is 3.06 μm.
[0041]Tungsten powder (200 kg) was added to carbon black (13.15 kg) for 6 hours in the plow mixer, and W + C mixture was obtained.
[0042]The W + C mixture 10g was pressed into a standard measuring mass 6.5 mm * 5.25 mm * 20 mm, placed in a high temperature carbonization furnace (small repair) and the product was carbonized with the product with the product, and the optical infrared thermometer showed the carbonization temperature 1910 ° C.
[0043]It was measured using a thousand-grid after carbonized standard measuring blocks, and the long size was 5.388 mm, 4.352 mm, 16.580 mm, and the computational shrinkage ratio was 17.10%, and the current carbonization temperature was 1910 ° C. Described that the current surface display carbonization temperature is consistent with the calibration temperature, and the performance of the high-temperature carbonization furnace has not change...
