Ungakhetha kanjani ukushisa kwe- ukucima imvamisa ephezulu nokwelashwa ngamakhaza

Mayelana nokukhethwa kwamazinga okushisa ekwelapheni amakhaza lapho kucima imvamisa ephezulu, abantu abaningi bahlala becabanga ukuthi ukwehla kwezinga lokushisa, kungcono. Akulona iqiniso lelo? Kulezi zinsuku, ukusetshenziswa kokwelashwa okubandayo kweqhwa kukhula ngokwengeziwe, futhi kunezinhlobo eziningi zamazinga okushisa okubanda okubandayo. Isibonelo, ususe ama-degree angama-70, ususe ama-degree angama-120, ususe ama-degree angama-190, njalonjalo, ulikhetha kanjani ithempelesha yokwelashwa okubandayo? Ingabe izinga lokushisa liphansi liba ngcono?

Okokuqala, izinga lokushisa lokuphelisa imvamisa ephezulu kanye nokwelashwa ngamakhaza kakhulu kuncike emazingeni okushisa ka-Ms no-Mf ensimbi, futhi kuhlobene nezidingo zobuchwepheshe zezingxenye. Ukwelashwa okubanda iqhwa kwemishini yokuqeda ukuqhubeka kwenqubo yokuqeda. Ukushesha kakhulu kuzodala kalula ukusonteka okukhulu nokuqhekeka. Ukuhamba kancane kakhulu kuzodala ukuguga okukhubazekile. Ngokuyisisekelo, kuseseyindima yokuhlanganisa izinto enquma ukuthi ngabe yini engenasisekelo Ukuzinza kukaNks noMf kuthinteka ngokuqukethwe okuphezulu kwama-alloying element, futhi ukuzinza kwe-austenite ngokuvamile kuphezulu. Ngemuva kokucima, kuzoba nokukhubazeka okuningi, futhi izinga lokushisa ngesikhathi sokwelashwa okubandayo ngokuvamile liphansi. Umphumela wokushisa okuphansi uzoba ngcono, okwenza ushintsho luphelele ngokwengeziwe, kepha izindleko zokwehlisa izinga lokushisa kufanele zibe phezulu kakhulu kunezindleko zokukhuphula izinga lokushisa.

Inkinga yokukhubazeka nokuqhekeka ayihlangene nokushisa kokwelashwa okubandayo. Ihlobene nezinga lokupholisa. Uma yehla nge-1 degree ngehora, noma ngabe ingahle iye ku-0 degrees, akufanele iqhekeke.

Okwesibili, izinga lokushisa aliphansi ngangokunokwenzeka. Izinga lokushisa elibandayo kufanele likhethwe ngokuya ngohlelo lokusebenza langempela! Isibonelo, ekwelashweni kwe-cryogenic yamasongo wokuthwala, iphuzu le-Mf kufanele libe ngaphansi kuka-70 kuya ku-80 degrees, futhi eliphakeme kakhulu lingafinyelela kuma-degree angama-80, ngakho-ke khetha iqhwa elomile njengezinto ezicutshungulwa nge-Cryogenically, lokhu sekuvele kwanele ukusetshenziswa.

Ngokuphathelene nezinkinga ze-cryogenic: insimbi yensimbi ingu -180 ° C (i-nitrogen ewuketshezi), insimbi ejwayelekile yokwakheka i-cryogenically -80 ° C (isiqandisi), ithuluzi nensimbi yesikhunta enezakhiwo eziyinkimbinkimbi kuqala ukufutheliswa ku-100 ° C-120 ° C, bese Yenza ukupholisa okujulile. Ngemuva kokuthi ukupholisa kwe-cryogenic kudlulile, linda ukuthi okokusebenza kukhuphuke kufudumele lasekamelweni ngaphambi kokushisa.

Ukucima imvamisa ephezulu kunezinhlobonhlobo zezinhlelo zokusebenza, futhi ukuqonda okuphelele nobuchule balobu buchwepheshe namakhono kungasebenza kangcono ekukhiqizeni. Ungafunda kabanzi ngalezi zinsimbi zokucima izinto njengokufaka ipayipi likakhonkolo ithuluzi langaphakathi lokucisha udonga, imishini yokuqeda imvamisa emaphakathi, imishini yokuqeda igiya, njll. Ukuphathwa kahle kwemishini yokucima kungenza le mishini isebenze kangcono, ukuze idale izinzuzo ezinkulu.
