Advantages of vacuum sintering furnace
Keuntungan tungku sintering vakum
1. It is easier to control the carbon content: under the condition of vacuum sintering temperature, the pressure in the furnace is only tens of Pascals (Pa) or even lower, O2, N2, H2 and H2O molecules are very few, and many reactions can be ignored. The impact is very small. As long as the dewaxing process is strictly controlled, the carbon content of the alloy changes very little during the vacuum sintering process, and the performance and structure are quite stable.
2. Dapat meningkatkan kemurnian paduan sinter: di bawah kondisi sintering vakum, ini bermanfaat untuk pengurangan oksida logam; seluruh siklus sintering tidak perlu membuka pintu tungku, tidak ada udara yang masuk, dan hampir tidak ada reaksi N2 dan O2.
3. Dapat meningkatkan sifat fase padat paduan: dalam kondisi sintering vakum, permukaan fase keras menyerap lebih sedikit kotoran, meningkatkan keterbasahan bor ke fase keras, dan meningkatkan kekuatan paduan, terutama paduan mengandung TiC.
4. Proses operasinya sederhana: karena pengisi dapat dihilangkan selama sintering vakum, ini tidak hanya menyederhanakan operasi, tetapi juga menghindari efek buruk pengisi pada permukaan tubuh yang disinter.
5. Various temperature sintering can be realized: temperature, atmosphere and furnace pressure can be controlled separately in temperature sections, and isothermal sintering (heat preservation) at any temperature can be realized, and multiple functions can be completed, such as gradient alloy sintering.
