I-vacuum yokuthambisa i-finching ayisiyo nje ukuyibeka kwi-leceace kwaye ishushu kwaye ipholise.

Ayisiyo isixhobo esibizayo yingxaki, kodwa ihlwempu elihlwempuzekileyo -}}}}} I-batch enye yezixhobo inokubiza amakhulu amawaka eYuan, kodwa iinkcukacha ezingalunganga zingonakalisa yonke into. Ingakumbi xa usebenzisa i-vacum yezixhobo zokucingela, abanini abaninzi bacinga ukuba indawo ecocekileyo kunye neqondo lobushushu elichanekileyo yonke le nto ifunekayo. Kodwa xa amalungu avele esikhundleni, umphezulu ubonakala utshaba, kodwa xa uhlola, uphawu olungapheliyo, kwaye nokuba yintoni ingxaki? Ngapha koko, ukucuthwa kwe-vacuum kunokubonakala ngathi yinkqubo elula: Ukufudumeza Ukungakhathali okuncinci kunokuwonakalisa yonke imigudu yakho . 1.} Abantu abaninzi, bethatha indlela elula yokuphuma, baphembelela ngebhasikithi yamalungu kwaye bawabambe. Kodwa ngaba ukhe wakuthathela ingqalelo: injani i-moya? Ukupholisa okungalinganiyo kuthetha ukuba iqondo lobushushu kwindawo enethunzi lehla kancinci, kwaye i-Microstlstonation engundoqo ihlanza iguqukile, ekhokelela ekungazalisiyo inguqu. Inkqubo echanekileyo: Shiya isithuba esiphezulu phakathi kwamalungu ukunqanda ukungqubana; Indawo enamacala amade kwiziko nakwiindawo ezimfutshane zebhodi ukuqinisekisa ukuhamba nomoya kwikona nganye; Lungisa itreyi ngokufanelekileyo ukuthintela ukuvimba i-duct yokupholisa. Le ayisiyonto yokhetho; Yinkqubo yeNkqubo Kwindawo yokuphumla, akukho nkokelo; Utshintshelo lobushushu luvela ngokupheleleyo kwimitha. Ukuba amaqondo obushushu anyuka ngokukhawuleza, ingakumbi i-{{14} Isindululo: Kwimibumba esine-cr12mov kunye ne-H13, okanye i-H13, okanye i-Hownieces emikhulu, ukubonelela ngamaxesha angama-30 kwimizuzu engama-30 ukuvumela amaqondo obushushu angaphakathi kunye nangaphandle ukuze alingane. Preuthere ngokufanelekileyo kwaye uphephe amanyathelo okutsiba. Ukuhambahamba kancinci kuyinto ekhuselekileyo . 3.}} ukuya kula kwaye ukupholisa: eyona ibaluleke kakhulu kwaye ifanelekile ukuba ingaphumeleli. Most vacuum furnaces use high-purity nitrogen or argon for pressurized quenching, with pressures generally ranging from 0.6–2.0 MPa. Nangona kunjalo, iifektri ezininzi zigxile kuphela kwi-semint, hayi eyona ntsebenzo. Iingxaki eziqhelekileyo: Ukucoceka kwerhasi ayonelanga, ioksijini okanye umxholo wokufuma kuchaphazela isantya sokupholisa kunye nomgangatho womhlaba; I-nozzle block okanye ukunciphisa ukusebenza kakuhle kw kukhokelela ekupholeni okungalinganiyo; Lack of step-by-step pressure control, resulting in high pressure from the start, can cause part deformation. Iingcebiso: Rhoqo Jonga i-Dew Dew Vinta ukuqinisekisa ukoshiswa; Jonga imeko ye fan kunye ne-nozzle ngaphambi kokucingela; Kwindlela yokusebenza enzima, "i-charrication" i-{pre {50} {i-37}}}}}}}} ulinde ixesha elide ukuba isuse i-coctoriece ukusuka kwiziko. Nje ukuba iziko limisiwe, abantu abaninzi abangxami ukuba basuse iinxalenye, becinga ukuba "ixesha elincinci liya kwenza iqhinga." Nangona kunjalo, iziko le-vacuum litshisiwe kakuhle, kwaye amalungu athole kancinci ngaphakathi, enokuba ngaphezulu kokungaphezulu kweyona nto iphambili -] Yintoni eyona nto ibaluleke kakhulu kukuba ezinye izinto ezenziwa nguMartiatic zihlala kwindawo yobushushu ephantsi ixesha elide kwaye zithambekele ku-rocks.
