Okuthunyelwe kwakha ukwelashwa kokushisa kokukhokhiswa kwensimbi engagqwali, owaziwa nangokuthi ukwelashwa kokushisa kokushisa noma ukwelashwa okuvuthayo, kuvame ukwenziwa ngokushesha ngemuva kokuqedwa kwenqubo yokuvuselela, futhi kunezindlela eziningi ezifana nokusebenzisa i-spherling, ikhambi eliqinile, Njll Namuhla sizofunda mayelana nalabo abaningi.

Ukuhlelwa okujwayelekile: Inhloso esemqoka ukucwilisa usayizi wokusanhlamvu. Shisisa lokhu okusolwa ngenhla kwezinga lokushisa lesigaba lesigaba ukuze wakhe isakhiwo esisodwa se-Auucenite, uzinze ngemuva kwesikhathi sokushisa okufanayo, bese uyikhipha esithandweni somlilo wokupholisa umoya. Isilinganiso sokushisa ngesikhathi sokujwayelekile kufanele siphuze ngaphansi kwama-700℃ukunciphisa umehluko wokushisa wangaphakathi nangaphandle kwangaphandle kanye nengcindezi ekhokhwayo ngaso leso sikhathi. Kungcono ukwengeza isinyathelo se-isother State phakathi kuka-650℃futhi 700℃; Emazingeni okushisa angenhla kwama-700℃, ikakhulukazi ngenhla kwe-AC1 (Ithango Lokuguqula Isigaba), izinga lokushisa lokukhokhiswa okukhulu kufanele likhuphuke ukuze lifinyelele imiphumela engcono yokucolisiswa okusanhlamvu. Uhla lokushisa lokujwayelekile luvame phakathi kuka-760℃futhi 950℃, ngokuya nge-Phase Transition Point enokuqukethwe okuhlukile kwengxenye. Imvamisa, okuqukethwe kwekhabhoni nokuqukethwe kwe-alloy, okuphezulu kokushisa okujwayelekile, okuphambene nalokho. Amanye amabanga akhethekile ensimbi angafinyelela ebangeni lokushisa le-1000℃kuya ku-1150℃. Kodwa-ke, ukuguqulwa kwesakhiwo kwensimbi engenasici kanye nezinsimbi ezingezona ze-Ferrous kutholakala ngokwelashwa kwesisombululo esiqinile.

Ukusuka: Inhloso esemqoka ukukhulisa i-hydrogen. Futhi ingaqinisa futhi i-microskruction ngemuva kwenguquko yesigaba, yasusa ukucindezela kwenguquko yokwakheka futhi yehlise ubunzima, okwenza kube lula ukubhekana nokukholelwa ukuthi kube lula ukucubungula ngaphandle kwe-deformation. Kunamazinga amathathu okushisa avumayo, okungukuthi okushisa okuphezulu okushisa (500℃~ 660℃), Ukushisa okushisa okuphakathi (350℃~ 490℃), kanye nokushisa okuphansi okuphansi (150℃~ 250℃). Ukukhiqizwa okujwayelekile kokuthethwa okukhulu kwamukele indlela ephezulu yokushisa. Ukufutheka kuvame ukwenziwa ngokushesha ngemuva kokujwayelekile. Lapho okujwayelekile ukucebisa kupholile ku-220℃~ 300℃, kuyavuselelwa, kuhlotshiswe ngokulinganayo, futhi kufakwe ngaphakathi esithandweni somlilo, bese kuphokwa ngaphansi kwama-250℃~ 350℃ebusweni bokubikwa ngaphambi kokudedelwa esithandweni somlilo. Izinga elipholile ngemuva kokushiswa komoya kufanele liphuze ngokwanele ukuvikela ukwakheka kwamabala amhlophe ngenxa yokuxineka ngokweqile ngesikhathi senqubo yokupholisa, futhi ukunciphisa ukucindezelwa okuseleyo ekusebenzeni ngangokunokwenzeka. Inqubo yokupholisa imvamisa ihlukaniswe izigaba ezimbili: ngenhla 400℃, njengoba insimbi isezingeni lokushisa elinobubanzi obuhle nobuningi be-brittleness, izinga lokupholisa lingashesha ngokushesha; Ngaphansi kwama-400℃, njengoba lensimbi ifake ibanga lokushisa elinobunzima obubandayo obubandayo kanye nobucwebe, izinga lokupholisa kancane kufanele kwamukelwe ukugwema ukuqhekeka nokunciphisa ukucindezela okusheshayo. Ngensimbi ezwela amabala amhlophe kanye ne-hydrogen emflittlement, kuyadingeka ukunquma ukunwetshwa kwesikhathi sokunwetshwa kwe-hydrogen kususelwa ku-hydrogen okulingana, ukuze kuncishiswe futhi kuchichime futhi kuchichime i-hydrogen , bese uyinciphisa ebangeni elivikelekile.

Ukunxusa: izinga lokushisa lifaka lonke uhla lokujwayelekile nokusula (150℃~ 950℃), usebenzisa indlela yokupholisa yokuthwala, efana nokugunda. Hlangana nge-Heating Littete ngenhla kwe-Phase Transition Point (izinga lokushisa elijwayelekile) libizwa ngokuthi yi-anvealing ephelele. Ukungena ngaphandle kwenguquko yesigaba ibizwa ngokuthi yi-Anveling engaphelele. Inhloso enkulu yokudubula ukuqeda ukucindezelwa futhi uzinze i-micross streating ngemuva kokushisa okubandayo kanye nokushisa okushisa ngemuva kokushiswa kwe-welding, njll. Ukushiswa + ukufutheka kuyindlela ethuthukile kakhulu kunenguquko ezanele yesigaba kanye nenguquko yesakhiwo, kanye nenqubo yokunwebeka engapheli ye-hydrogen.
