Unyango lobushushu yinkqubo ebalulekileyo kwimveliso yemizi-mveliso. Lubandakanya ukufudumeza nokupholisa iindawo zesinyithi ukuphucula iimpawu zazo zoomatshini, ezinje ngokuqina, ukuqina kunye nokumelana nokuguguleka. Nangona kunjalo, ayizizo zonke iindlela zonyango lobushushu ezidalwe zilingana. Ezinye zinokubangela ukuguquka okugqithisileyo okanye zide zonakalise iindawo. Kulapho ke izitofu zokucima umoya nge-vacuum zisebenza khona.
Isithando sokucima umoya se-vacuumluhlobo lwezixhobo zonyango lobushushu, ezisebenzisa igesi enoxinzelelo oluphezulu ukufudumeza iindawo kwi-vacuum zize zizipholise. Kwenziwa i-vacuum ukuthintela nayiphi na i-oxidation okanye ungcoliseko ukuba lungenzeki, kwaye igesi (edla ngokuba yi-nitrogen okanye i-helium) isetyenziselwa ukucima loo ndawo ngokukhawuleza nangokulinganayo.
Ukucima i-vacuum kuthathwa njengenye yezona ndlela zibalaseleyo zokufezekisa ulungelelwaniso olungcono lobunzima kunye nokuqina kwiindawo zesinyithi. Kuvelisa isakhiwo esincinci esincinci ngaphandle kokususwa kwe-carburization okanye ukuguqulwa komphezulu, okubangela iipropati ezintle zoomatshini kunye nobomi benkonzo ende. Ukongeza, izitofu zokucima i-vacuum zinokuphatha iintlobo ngeentlobo zezinto, ukusuka kwintsimbi kunye nentsimbi engatyiwayo ukuya kwi-aluminium kunye ne-titanium alloys.
Ukuze ufumane iingenelo ezipheleleyo zokuqinisa nge-vacuum, udinga isixhobo esithembekileyo nesisebenzayoisithando sokucima ulweloIsitovu esilungileyo kufuneka sibe nezi mpawu zilandelayo:
- I-vacuum ephezulu: Okona kulungileyo kukuba, i-furnace ifanele ukuba ikwazi ukufikelela kwi-vacuum ye-10^-5 Torr okanye ngaphantsi ukunciphisa i-oxidation kunye nongcoliseko.
- Ukucima ngokukhawuleza: isithando somlilo kufuneka sikwazi ukupholisa indawo kwi-10-50°C/s ukuze kufezekiswe isakhiwo esifunekayo.
- Ukusasazwa kobushushu obufanayo: Isithando somlilo kufuneka sibe nenkqubo yokufudumeza eyilwe kakuhle esasaza ubushushu ngokulinganayo kulo lonke isithando somlilo ukuqinisekisa iziphumo zokucima ezifanayo.
- Inkqubo yokulawula ephucukileyo: Isithando somlilo kufuneka sibe nephaneli yokulawula elula ukuyisebenzisa evumela ulawulo oluchanekileyo lobushushu kunye nokuhamba kwegesi, kunye nokubeka esweni kunye nokurekhoda idatha yenkqubo.
At PaijinSinikezela ngoluhlu olubanzi lwee-vacuum quenching furnace ezihlangabezana nezi mfuno kunye nokunye. Ii-furnace zethu ziyilwe kwaye zakhiwe kusetyenziswa ubuchwepheshe bamva nje kunye nezixhobo liqela elinamava leenjineli kunye neengcali. Sikwabonelela ngezisombululo ezenzelwe wena ukuhlangabezana neemfuno zakho ezithile kunye neemfuno zakho.
Ezinye zeemodeli zethu ezidumileyo ziquka:
- Isithando somlilo esicima umoya ophuma kwi-vacuum cleaner: esi sithando sinokusingatha iindawo ezifikelela kwi-2000mm ubude kunye ne-1500kg ubunzima, kunye nobushushu obuphezulu be-1350°C kunye nesantya sokuphola esikhawulezayo se-30°C/s.
- Isithando somlilo esicima umoya we-vacuum esithe tye: Esi sithando somlilo sinokucubungula iindawo ezinobubanzi obuphezulu be-1000mm kunye nobunzima be-1000kg, kunye nobushushu obuphezulu be-1350°C kunye nesantya sokuphola esikhawulezayo se-50°C/s.
- Isithando somoya esisetyenziselwa imisebenzi emininzi: Esi sithando singasetyenziselwa iinkqubo ezahlukeneyo zonyango lobushushu ezifanaukucima i-vacuum, ukufudumala, ukuqhoboshela, ukurhawuzelela, njl.njl., kunye nobushushu obuphezulu be-1300°C kunye neqondo lokucoca eliyi-10^-5 Torr.
Ukuqukumbela, ii-furnaces zokucima umoya nge-vacuum zizixhobo ezibalulekileyo zokufumana iziphumo zonyango lobushushu ezisemgangathweni ophezulu nezihlala zihleli. Zibonelela ngokusebenza okuphezulu, ukusebenza kakuhle kunye nokuguquguquka xa kuthelekiswa nezinye iindlela zonyango lobushushu. Ukuba ufuna i-furnaces ethembekileyo nesebenzayo, jonga uluhlu lwee-furnaces zokucima umoya nge-vacuum zikaPaijin namhlanje!
