1.Foreword:
At present, the research on WC material effect on the properties of alloy has become a research direction, improve the carbide for WC raw material production factory, can provide users with high-quality raw materials is currently a major issue.Through domestic related information and related experimental research, can determine the carbon content of WC on WC – Co carbide performance has very important influence.
When the carbide composition, grain size and manufacturing technology of cemented carbide is determined after the production process of carbon control, is the core of cemented carbide for quality control.And the carbon content in the WC directly affects the carbon content of carbide. the WC carbon content, hardness, density, magnetic force, magnetic saturation,alloy grain size.
- Test way:
Choose different WC carbide content do 1KG alloy appraisal (manufacturing process is the same)With the shaft machine wet grinding ball mill barrel, 20 t hand and press forming technology, vacuum sintering furnace for sintering test.The experiment process is as follows:
- Ingredients:
WC(g) | Co(g) | alcohol(m1) | |
900 | 100 | 370 |
- Wet grinding:
Ball material ratio | Ball mill time(h) |
2.4:1 | 10 |
- Suppression:
Suppression pressure(t) | Single weight(g) |
10 | 14 |
4) Sintering:
Sintering temperature(℃) | Heat preservation time(min) |
1420 | 60 |
3.Test results and analysis
1)The influence of WC Carbon Content on carbide density:
Total carbon(%) | 6.08 | 6.09 | 6.1 | 6.11 | 6.12 | 6.13 | 6.14 | 6.15 |
density(g/cm3) | 14.49 | 14.59 | 14.52 | 14.51 | 14.54 | 14.54 | 14.43 | 14.45 |
It can be seen, the carbon content in the 6.08-6.09 WC, the WC with increasing carbon content, the density of the alloy gradually increase; the carbon content in the 6.09-6.12 when WC, increases, the density of WC alloy of carbon content gradually decrease; the carbon content in the 6.12-6.13 WC, the WC with increasing carbon content, the density of the alloy gradually increase; the carbon content in the 6.13-6.14 WC, the WC with increasing carbon content, alloy density gradually decreased; WC of when the carbon content in the 6.14-6.13, with the increase of carbon content of WC, gradually increase the density of the alloy.
2)The influence of WC Carbon Content on carbide:
Total carbon % | 6.08 | 6.09 | 6.1 | 6.11 | 6.12 | 6.13 | 6.14 | 6.15 |
Hardness(HRA) | 88.6 | 90.3 | 90.9 | 88.7 | 87.8 | 88.5 | 88.5 | 88.4 |
It can be seen, the carbon content in the 6.08-6.10 WC, the WC with increasing carbon content, the hardness of the alloy gradually increase; the carbon content in the 6.10-6.12 WC, the WC with increasing carbon content, the hardness of the alloy gradually decrease; the carbon content in the 6.12-6.13 WC, the WC with increasing carbon content, the hardness of the alloy gradually increase; the carbon content in the 6.13-6.16 WC, the WC with increasing carbon content, the hardness of the alloy decreased gradually.
3)The influence of WC Carbon Content on carbide Magnetic force:
Total carbon(%) | 6.08 | 6.09 | 6.1 | 6.11 | 6.12 | 6.13 | 6.14 | 6.15 |
Magnetic force(KA/m) | 10.1 | 16 | 12.3 | 7.5 | 6.9 | 8.1 | 7.8 | 6.4 |
It can be seen, the carbon content in the 6.08-6.09 WC, the WC with increasing carbon content, alloy magnetic force gradually increase; the carbon content in the 6.10-6.12 WC, the WC with increasing carbon content, alloy magnetic force gradually lower.
- The influence ofWC Carbon Content on carbide magnetic saturation:
Total carbon(%) | 6.08 | 6.09 | 6.1 | 6.11 | 6.12 | 6.13 | 6.14 | 6.15 |
magnetic saturation(%) | 14.5 | 10.6 | 13.6 | 14.2 | 14.8 | 14.5 | 14.7 | 14.6 |
It can be seen, the carbon content in the 6.08-6.09 WC, the WC with increasing carbon content of the alloy progressively reduces magnetic saturation; in 6.09-6.6.16 increase with increasing carbon content of WC WC carbon content, alloy magnetic saturation gradually increased.
- The influence ofWC Carbon Content on carbide grain size:
Total carbon(%) | 6.08 | 6.09 | 6.1 | 6.11 | 6.12 | 6.13 | 6.14 | 6.15 |
Grain size(μm) | 1.2 | 1.2 | 1 | 2 | 2.4 | 2 | 2 | 2 |
It can be seen, the carbon content in the 6.08-6.10 WC, the WC with increasing carbon content, alloy grain size gradually reduced; the carbon content in the 6.10-6.16 WC, the WC with increasing carbon content, alloy grain size gradually increases.
- Conclusion:
By choosing different carbon contents in the same conditions do 1Kg WC alloy identified by 1,2,3,4,5 can be seen with increasing carbon content of WC carbide density, hardness, magnetic reduced magnetic saturation alloy, alloy grain size increases.
