Isixazululo esikhanyayo se-annealing esihlinzekwa -H angao ubuchwepheshe be -anneal ed elikhanyayo senza ishubhu le elibushelelezi ngaphakathi nangaphandle, ukubekezelela okunembayo kwe-dimensional, amandla aphezulu, ukumelana nokugqwala okuqinile nokunye.Ishubhu elinjalo lingafinyelelwa kanjani?
Insimbi engagqwali ye-Austenitic isetshenziswa kabanzi emisebenzini ehlukahlukene yomphakathi, yezimboni nezempi.Atholakala ngezindlela ezihlukahlukene zomkhiqizo, njengemigoqo, izinduku, amashidi, amashidi, amapheshana, ucwecwe, amashubhu, amashubhu, okokufakwayo, ama-flange nokunye.
Uma insimbi engagqwali iphathwa ukushisa esithandweni esivamile, ingxenye ye-chromium kunsimbi engagqwali ye-austenitic izosabela komoyampilo emoyeni ukuze yakhe ungqimba olumpunga lwe-oxide, olubizwa 'scale', okufanele lususwe ngenqubo yokukhetha.
Isixazululo esikhanyayo se-annealing singayithuthukisa le nqubo.Ukuze ulondoloze ukubukeka okuhle, gcina ukucwebezela kwe-metallic yasekuqaleni futhi ugweme ukucosha, insimbi engagqwali ye-austenitic kufanele ikhanyiswe ifakwe ekuvikelekeni noma i-vacuum ukuvimbela ukuguquguquka kwendawo.Wonke amabanga ensimbi engagqwali ye-austenitic angabanjwa.Umkhathi ovikelayo ungaba i-hydrogen emsulwa, i-ammonia ehlukanisiwe, noma ngezinye izikhathi i-vacuum.Igesi evikelayo ivimbela i-oxidation engaphezulu yemikhiqizo yensimbi engenasici ye-austenitic ngesikhathi sokudonsa.
Ngakho isixazululo esikhanyayo se-annealing sinezinzuzo ezilandelayo:
I-1, i-annealing ekhanyayo ayigcini nje ukunciphisa ubulukhuni bepayipi lensimbi, ithuthukise i-ductility, ithuthukise i-plasticity, kodwa futhi kulula ukuyisika kanye nokuguqulwa okubandayo.
2, thuthukisa ukumelana nokugqwala ngokususa imvula ye-intergranular carbide, ukuze ukubukeka komhlaba kube kuhle.Ukucwenga okusanhlamvu kanye nesakhiwo esifanayo sensimbi nokubunjwa, ukuthuthukisa izakhiwo zensimbi, kodwa futhi kulungiselele ukwelashwa kokushisa.
3, susa ukucindezeleka kwangaphakathi okusele ensimbi, vimbela ukuguquguquka nokuqhekeka.
4. I-oxidation kanye ne-decarbonization kwenzeka ngesikhathi sokushisa nokupholisa ku-annealing evamile, ngakho insimbi efakwe ukushisa iye yacutshungulwa ngokwengeziwe, okwandisa ukulahlekelwa kanye nezindleko zensimbi.
5. ungatholi i-oxidation ekhanyayo, indawo enhle yokumelana nokugqwala.Ngenxa yokuthi i-annealing ekhanyayo iwukwelapha ukushisa kwe-strip steel endaweni evikelayo yengxube ye-hydrogen ne-nitrogen gas, indawo engaphezulu ngaphandle kwe-oxidation itholakala ngokulawula ngokuqinile igesi evikelayo esithandweni.Uma kuqhathaniswa nobuso obutholwe yi-annealing evamile kanye ne-pickling, ngenxa yokuthi ayikho inqubo ye-oxidation, isimo sokuntuleka kwe-chromium siyancishiswa phezulu, futhi ukumelana kwayo nokugqwala kuba ngcono ngemva kokupholisha.
6. ukwelashwa okukhanyayo ukuze kugcinwe ukuphela kwendawo egoqayo, akusakwazi ukucutshungulwa futhi kutholakale indawo ekhanyayo.Ngenxa ye-annealing ekhanyayo, ubuso be- tube bugcina i-luster yensimbi yokuqala, itholwe indawo ekhanyayo, ngaphansi kwezidingo ezijwayelekile, ingasetshenziswa ngokuqondile ngaphandle kokucubungula ubuso bayo.
7.Ayikho inkinga yokungcola ebangelwa indlela evamile yokukhetha.ene-annealed I-tube ayidingi ukuba yi-picling noma ukwelashwa okufanayo, ungasebenzisi i-asidi, azikho izinkinga zokungcola okubangelwa ukuqoqwa.
Pho safika kanjani lapho?
Okokusebenza kwe-On-line Fixing & Fusing (Anealing) kungashisisa ipayipi lensimbi engagqwali elishiselwe ku-1050 ° C bese lipholisa libe ngaphansi kwezinga lokushisa elingaphansi kuka-100 ° C ngaphansi kokuvikelwa kwe-hydrogen. Ukunikezwa kwamandla okushisa okungeniswa kweferquency emaphakathi yi-DSP entsha kakhulu. +Isakhiwo se-IGBT.Ngesistimu yokulawula idijithali ye-DSP, kukhona ukuzivikela kanye nemisebenzi yokuzihlola.Ngomthamo omncane, ishisisa amapayipi ngokushesha nangempumelelo ngezici zokonga amandla nezimoshi. insimbi ingonga amandla angu-15% -20% ngokungafani neminye imikhiqizo yesigaba esifanayo.Ukusebenzisa i-hydrongen njengegesi njalo ngomzuzu.
