Ama-vacuum furnaces ayisisetshenziswa esibalulekile embonini yesimanje. Ingakwazi ukusebenzisa izinqubo eziyinkimbinkimbi ezingakwazi ukusingathwa ezinye izinto zokwelashwa kokushisa, okuwukuthi ukucisha i-vacuum nokufudumeza, ukuvala i-vacuum annealing, isixazululo esiqinile se-vacuum kanye nesikhathi, i-vacuum sintering, ukwelashwa kwamakhemikhali e-vacuum kanye nezinqubo zokumboza i-vacuum. Ukushisa kwayo kwesithando somlilo kungafinyelela ku-3000 ℃, futhi i-tungsten ne-molybdenum inokumelana okuhle kwezinga lokushisa eliphezulu kanye ne-coefficient ephansi yokwandisa ukushisa, ngakho-ke ivame ukusetshenziswa njengezesekeli ezithile esithandweni somlilo.
Ngokuvamile, lapho izinga lokushisa lomlilo lingaphezu kuka-1100 degrees Celsius, i-molybdenum noma i-tungsten izobhekwa njengesivikelo sokushisa (okuhlanganisa ama-baffles aseceleni kanye nezikrini zekhava ezingaphezulu nezingaphansi): njengezingxenye zokuvikela ukushisa esithandweni somlilo, indima ebalulekile ye-molybdenum. isikrini sesibonisi se-tungsten kanye namakhava angaphezulu nangaphansi Ipuleti elokuvimba nokuphinda liguqule ukushisa esithandweni. Ipuleti lokufaka ukushisa kwe-tungsten ne-molybdenum ngokuvamile lenziwa nge-riveting, elingabhodlozwa noma ligqitshwe. Amapuleti kathayela, amagridi amise okwe-U noma iziphethu zocingo ze-molybdenum nama-spacers angasetshenziswa phakathi kwezikrini zesendlalelo ngasinye, futhi ahlanganiswe nentambo ye-molybdenum noma iziqeshana zocingo lwe-tungsten nezikulufu.
| Igama lemikhiqizo | Amapharamitha |
| Ubumsulwa | Mo,W≥99.95% |
| Ukuminyana | I-Mo Material≥10.1g/cm3 noma impahla ye-tungsten≥19.1g/cm3 |
| Imvelo yokushisa yohlelo lokusebenza | ≤2800℃; |
| Izinga lokushisa le-Plastiki-brittle transition | W phakathi kuka-200-400℃ Mo uphakathi kuka-20-400 °C. |
| Umfutho we-vapor | I-W imayelana ne-10-6Pa ku-2100 ° C, i-Mo cishe i-10-2Pa ku-2100 ° C; |
| Ukusebenza kwe-Anti-oxidation | U-W ufakwa i-oxid ngokushesha endaweni ephakeme kuno-500°C emoyeni, futhi i-Mo ikhishwa nge-oxid ngokushesha ngaphezu kuka-400°C. Indawo yokusetshenziswa yesivikelo sokushisa se-tungsten noma isivikelo sokushisa se-molybdenum sidinga ukuba endaweni engenalutho noma engasebenzi. |
Abawinile be-Baoji bakhiqiza ngokuyinhloko i-tungsten ne-molybdenum nezinto zayo zengxubevange futhi zingenziwa ngendlela oyifisayo ukuhlangabezana nezidingo zamakhasimende. Ukuze uthole olunye ulwazi lomkhiqizo, sicela usithinte (Whatsapp: +86 156 1977 8518).
