Insimbi engagqwali isiphenduke into ebaluleke kakhulu embonini yesimanje ngenxa yokumelana nokugqwala okuhle kakhulu, amandla aphezulu, kanye nobuhle. Phakathi kwazo, ishidi lensimbi egxiviziwe eligxiviziwe lisetshenziswa kakhulu ezimotweni, izinto zikagesi zasendlini, ezokwakha kanye nezinye izinkambu ngenxa yokubukeka kwazo okuhle nokusebenza okubanzi. Lesi sihloko sizokwethula ngokuningiliziwe izici zayo nokusebenza, izinhlobo namamaki ensimbi, izimo zohlelo lokusebenza, nezinqubo zokukhiqiza.

(1) Izici nokusebenza kwamapuleti ensimbi engenasigxivizo

1. Izici zezinto
Ukumelana nokugqwala: Insimbi engagqwali iqukethe izakhi ze-alloy ezifana ne-chromium (Cr) ne-nickel (Ni), futhi ifilimu eminyene ye-oxide yakheka phezulu, engamelana nokugqwala ngemidiya efana nama-asidi, ama-alkali, nosawoti.

Amandla aphezulu kanye nokuqina: Inqubo yokugxiviza idinga ukuthi impahla ibe nakho kokubili ipulasitiki namandla. Insimbi engagqwali ingahlangabezana nezidingo ezihlukene zokugxiviza ngemva kokuginqika okubandayo noma ukwelashwa kokushisa.

Ukuqedwa kobuso: Ingaphezulu lamapuleti ensimbi engagqwali lingaphathwa ngokupholisha, ukuqhwaza, njll. ukuze kuhlangatshezwane nezidingo zokuhlobisa.

2, Izinzuzo zenqubo

Ukwakheka okuhle: Amapuleti ensimbi engagqwali ane-ductility ephezulu futhi afanele ukunyathela kobunjwa obuyinkimbinkimbi (njengokwelula nokugoba).

Ukuzinza kwe-Dimensional: I-rebound encane ngemva kokugxivizwa, kanye nokunemba okuphezulu kwemikhiqizo eqediwe.

Ukuhambisana kokushisela nokupholisha: Izingxenye ezinesitembu zingashiselwa ngokuqhubekayo noma ziphuculwe ukuze kwandiswe izimo zohlelo.

3, Ukuzivumelanisa nezimo ezidingweni ezikhethekile

Amanye amamaki ensimbi (afana no-316L) anokumelana nokushisa okuphezulu futhi afanele izindawo zokushisa eziphezulu; insimbi engagqwali eyi-duplex inokubili amandla aphezulu kanye nokumelana nokugqwala.

(2) Izinhlobo zamapuleti ensimbi engenasici kanye namamaki ensimbi avame ukusetshenziswa

Ngokusekelwe kusakhiwo se-metallographic kanye nokwakheka kwamakhemikhali, insimbi engagqwali ingahlukaniswa ngezigaba ezilandelayo:

(3) Izindawo zokufaka izicelo zeshidi lensimbi engenasici

1. Ukukhiqiza izimoto

Isistimu ye-exhaust: 409L/439 insimbi engagqwali ye-ferritic isetshenziselwa izingxenye zokugxiviza zepayipi, elimelana ne-oxidation yokushisa ephezulu.

Izingxenye zesakhiwo: Insimbi enezigaba ezimbili ezinamandla aphezulu isetshenziselwa imishayo yokunqanda ukushayisana kweminyango, ecabangela kokubili ukukhanya nokuphepha.

2. Imboni yemishini yasendlini

Umshini wokuwasha umgqomo wangaphakathi: Insimbi engagqwali engu-304 igxiviziwe futhi yakheka, ekwazi ukumelana nokuguguleka kwamanzi futhi inobuso obushelelezi.

Imishini yasekhishini: Insimbi engagqwali engu-430 isetshenziselwa amaphaneli e-hood, okulula ukuwahlanza futhi alawulwa yizindleko.

3. Umhlobiso wezakhiwo

Udonga lwamakhethini kanye ne-elevator trim:I-304/316 insimbi engagqwali inesitembu futhi yaqoshwa, enhle futhi ehlala isikhathi eside.

4, Imishini yezokwelapha nokudla

Izinsimbi zokuhlinza: Izingxenye zokugxiviza zensimbi engenasici ezingu-316L zimelana nokugqwala komzimba futhi zihlangabezana nezindinganiso zokuhlanzeka.

Izitsha zokudla: Amathangi ensimbi engagqwali agxiviziwe angu-304 ahlangabezana nezidingo zokuphepha kokudla.

(4) , Inqubo yokukhiqiza yeshidi lensimbi engenasigxivizo

Inqubo yokukhiqiza ipuleti lensimbi engenasigxivizo ihlanganisa lezi zinyathelo ezibalulekile ezilandelayo:

1, Ukulungiselela impahla eluhlaza

Ukwenza insimbi nokusakazwa okuqhubekayo: Ukuncibilika ngesithando somlilo sikagesi noma isithando somlilo se-AOD, okulawula ingxenye yezinto ezifana ne-C, Cr, Ni.

Ukuginqika okushisayo nokugoqa okubandayo: Ngemva kokuginqika okushisayo kube amakhoyili, ukugoqa okubandayo ukuya kugqinsi okuqondiwe (imvamisa ku-0.3~3.0mm) ukuze kuthuthukiswe ukuphela kwendawo.

2, Ukwelashwa kwangaphambi kokugxiviza

Ukusika nokusika: Sika ipuleti ngokuvumelana nezidingo zesayizi.

Ukwelashwa kokugcotshwa: Faka uwoyela wokugxiviza ukuze unciphise ukuguga kwesikhunta kanye nokuklwebheka kwezinto.

3. Ukwakhiwa kwesitembu

Isikhunta design: Yakha isikhunta esiqhubekayo seziteshi eziningi noma isikhunta senqubo eyodwa ngokuya ngokuma kwengxenye, futhi ulawule igebe (imvamisa i-8% ~ 12% yobukhulu bepuleti).

Inqubo yokugxiviza: Ukwakhiwa ngezinyathelo ezifana nokuvala, ukwelula, nokuphehla, isivinini sokunyathela (njengezikhathi ezingu-20~40/umzuzu) nokucindezela kudinga ukulawulwa.

4, Ngemuva kokucubungula nokuhlolwa

Ukuxubha nokuxubha: qeda ukucindezeleka kokunyathela futhi ubuyisele i-plasticity yezinto ezibonakalayo (izinga lokushisa le-annealing: insimbi ye-austenitic 1010 ~ 1120 ℃).

Ukwelashwa kwendawo: i-electrolytic polishing, i-PVD coating, njll. ukuthuthukisa ukubukeka noma ukusebenza.

Ukuhlolwa kwekhwalithi: qinisekisa ukuthi usayizi nokumelana nokugqwala kuhlangabezana nezindinganiso ngokulinganisa okuhlanganisa ezintathu, ukuhlolwa kwesifutho sikasawoti, njll.

(5) Amathrendi Okuthuthukiswa Kwesikhathi esizayo

Amandla aphezulu kanye nesisindo esincane: Thuthukisa insimbi engagqwali ye-duplex yamandla aphezulu ukuze ungene esikhundleni sensimbi yendabuko ukuze unciphise isisindo.

Inqubo eluhlaza: Thuthukisa ubuchwepheshe bokugxiviza obungenawo uwoyela ukuze unciphise ingcindezi yemvelo yenqubo yokuhlanza.

Ukukhiqiza okuhlakaniphile: Hlanganisa ubuchwepheshe be-AI ukuze uthuthukise ukwakheka kwesikhunta namapharamitha wokugxiviza ukuze uthuthukise izinga lokukhiqiza.

—————————————————————————————

Isiphetho
Amashidi ensimbi engenazigxivizo ayaqhubeka nokukhuthaza ukuthuthukiswa kwemboni yokukhiqiza ngokulingana nokusebenza kwawo kanye nenqubo. Kusukela ekukhethweni kwezinto ezibonakalayo kuya ekuthuthukisweni kokukhiqiza, ukuqamba okusha kusixhumanisi ngasinye kuzoqhubeka nokwandisa imingcele yohlelo lokusebenza futhi kuhlangabezane nezidingo ezahlukahlukene zezimboni zesikhathi esizayo.
