Ukuze ugweme ukupholisa i-warping emva komatshini, ngokubanzi, i-tungsten carbide idinga ukuphathwa ngobushushu, emva kokufudumala, amandla esixhobo aya kuncitshiswa emva kokufudumala, kwaye iplastiki kunye nokuqina kwe-carbide ene-cemented kuya kwanda. Ngoko ke, kwi-carbide ene-cemented, unyango lobushushu yinkqubo ebaluleke ngakumbi. Namhlanje, umhleli weChuangrui uya kuthetha nawe malunga nolwazi olufanelekileyo lonyango lwe-vacuum.
Ekuqhutyweni nasekuveliseni unyango lwe-vacuum yokushisa, kukho rhoqo iingxaki "zombala" kumphezulu weemveliso ezicutshungulwayo. Ukufikelela kwimbonakalo eqaqambileyo, isiphumo sokusetyenzwa kwemveliso engenambala yinjongo eqhelekileyo elandelwa yiR&D kunye nabasebenzisi beziko lokufunxa. Ngoko yintoni isizathu sokukhanya? Ziziphi izinto ezibandakanyekileyo? Ndingayenza njani imveliso yam ibengezele? Lo ngumcimbi oxhalabisa kakhulu kumagcisa angaphambili kwimveliso.
Umbala ubangelwa yi-oxidation, kwaye imibala eyahlukileyo inxulumene nobushushu obuveliswayo kunye nobukhulu befilimu ye-oxide. Ukucima i-oyile kwi-1200 ° C kuya kubangela ukuba i-carburizing kunye nokunyibilika komgangatho ongaphezulu, kwaye i-vacuum ephezulu kakhulu iya kubangela ukuguquguquka kwezinto kunye nokudibanisa. Ezi zingonakalisa ukuqaqamba komphezulu.
Ukuze ufumane umgangatho oqaqambileyo ongcono, la manyathelo alandelayo kufuneka anikwe ingqwalasela kwaye aqwalaselwe kwindlela yokuvelisa:
1. Okokuqala, iimpawu zobugcisa zesithando somlilo kufuneka zihlangabezane nemigangatho kazwelonke.
2. Inkqubo yonyango kufuneka ibe nengqiqo kwaye ichaneke.
3. Isithando somlilo asifanele singcoliswe.
4. Ukuba kuyimfuneko, hlamba isithando somlilo nge-high-purity gas inert ngaphambi kokungena kunye nokushiya isithando somlilo.
5. Kufuneka idlule kwi-oven enengqiqo kwangaphambili.
I-6.Ukhetho olufanelekileyo lwegesi ye-inert (okanye inxalenye ethile yegesi yokunciphisa enamandla) ngexesha lokupholisa.
Kulula ukufumana indawo ecwebezelayo kwiziko lokufunxa kuba akulula kwaye kuyabiza ukufumana umoya okhuselayo onombethe ongu-74°C. Nangona kunjalo, kulula ukufumana umoya we-vacuum kunye nendawo yombethe elingana ne -74 ° C kunye nomxholo wokungcola okufanayo. Ekuqhubeni nasekuveliseni unyango lwe-vacuum yokushisa, insimbi engenasici, i-titanium alloy, kunye ne-high-temperature alloy inzima kakhulu. Ukuze kuthintelwe ukuguquguquka kwezinto, uxinzelelo (i-vacuum) yensimbi yesixhobo kufuneka ilawulwe kwi-70-130Pa.
