Ukuthengwa Okuphezulu Kwepuleti Leshidi Lensimbi Engagqwali - I-China ithumela ngaphandle ipuleti lensimbi engagqwali - i-Huaxin

incazelo yomkhiqizo

Amashidi ensimbi engagqwali ngokuvamile ayitemu elivamile lamashidi ensimbi engagqwali namashidi ensimbi amelana ne-asidi. Ekuqaleni kwaleli khulu leminyaka, ukuthuthukiswa kwamapuleti ensimbi engagqwali kwabeka izinto ezibalulekile kanye nesisekelo sobuchwepheshe sokuthuthukiswa kwemboni yesimanje kanye nenqubekelaphambili yesayensi nezobuchwepheshe. Kunezinhlobo eziningi zamapuleti ensimbi engagqwali anezakhiwo ezihlukene, futhi kancane kancane iye yakha izigaba eziningana ezinkulu enqubweni yokuthuthukiswa. Ngokwesakhiwo senhlangano, ihlukaniswe yaba izigaba ezine: ipuleti lensimbi engagqwali ye-austenitic, ipuleti lensimbi engagqwali ye-Martens (okuhlanganisa imvula eqinile ipuleti lensimbi engagqwali), ipuleti lensimbi engagqwali ye-ferritic, nepuleti le-austenite kanye ne-ferrite duplex yensimbi engagqwali.

Ukwakheka kwamakhemikhali okuyinhloko noma ezinye izici ze-steel plate zihlukaniswa nge-chrome stainless steel plate, chrome nickel stainless steel plate, chrome nickel molybdenum stainless steel plate kanye ne-low carbon stainless steel plate, high molybdenum steel stainless steel plate. nokunye okunjalo. Ngokwezici zokusebenza nokuhlukaniswa kokusetshenziswa kwamapuleti ensimbi, ihlukaniswe yaba amapuleti ensimbi engagqwali ane-nitric acid, amapuleti ensimbi engenasici, amapuleti ensimbi engagqwali angagodli, amapuleti ensimbi engagqwali aqinile . Ihlukaniswe ngokwezici zokusebenza zepuleti lensimbi, ihlukaniswe ngepuleti lensimbi engenasici eliphansi lokushisa, ipuleti lensimbi elingenazibuthe, ipuleti lensimbi engagqwali elisikiwe mahhala, ipuleti lensimbi engenasici yepulasitiki nokunye.

Indlela yokuhlukanisa evame ukusetshenziswa ihlukaniswa ngokuvumelana nezici zesakhiwo sepuleti lensimbi kanye nokwakheka kwamakhemikhali epuleti lensimbi kanye nokuhlanganiswa kwakho kokubili. Ngokuvamile, ihlukaniswe ngepuleti lensimbi engenalutho ye-martensite, ipuleti lensimbi engagqwali ye-ferritic, ipuleti lensimbi engagqwali ye-austenitic, ipuleti lensimbi engagqwali eliyi-duplex kanye nemvula eqinisa ipuleti lensimbi engagqwali, noma ihlukaniswe izigaba ezimbili: ipuleti lensimbi engagqwali le-chrome kanye nepuleti lensimbi ye-nickel. Isetshenziswa kabanzi Izicelo ezijwayelekile: izishintshisi zokushisa zemishini nemishini yokwenza amaphepha, okokusebenza kwemishini, okokusebenza kokudaya, okokusebenza kwefilimu, amapayipi, izinto zangaphandle zezakhiwo ezisezindaweni ezisogwini, njll.

Ipuleti lensimbi engenasici linendawo ebushelelezi, ipulasitiki ephezulu, ukuqina namandla emishini, futhi imelana nokugqwala ngama-acids, amagesi e-alkaline, izixazululo neminye imidiya. Iyinsimbi engagqwali kalula, kodwa ayinayo nhlobo ukugqwala.

Izici Zomkhiqizo

Ukumelana nokugqwala
Ishidi lensimbi engagqwali linamandla okumelana nokugqwala okuvamile okufana ne-nichrome 304 engazinzile. Ukushisisa isikhathi eside ebangeni lokushisa le-chromium carbide kungase kuthinte ama-alloys 321 no-347 kumidiya elimazayo. Ikakhulukazi esetshenziswa ekusetshenzisweni kokushisa okuphezulu, izicelo zokushisa okuphezulu zidinga ukuzwela okunamandla kwezinto zokuvimbela ukugqwala kwe-intergranular emazingeni okushisa aphansi.

Ukumelana nokushisa okuphezulu kwe-oxidation
Amapuleti ensimbi engagqwali anokumelana nezinga lokushisa eliphezulu kwe-oxidation, kodwa izinga le-oxidation lithintwa izici ezingokwemvelo ezifana nemvelo eveziwe kanye nokumila komkhiqizo.

Izici ezingokomzimba
Ingqikithi yokudlulisa ukushisa kwe-coefficient yensimbi incike kwezinye izici, ngaphezu kwe-thermal conductivity yensimbi. Ezimweni eziningi, i-coefficient yokukhipha ukushisa kwefilimu, isikali kanye nesimo sensimbi. Insimbi engagqwali igcina indawo engaphezulu ihlanzekile futhi icocekile, ngakho-ke ukudlulisa ukushisa kwayo kungcono kunezinye izinsimbi ezine-thermal conductivity ephakeme. I-Liaocheng Suntory Stainless Steel inikeza izindinganiso zobuchwepheshe zamapuleti ensimbi engagqwali. Amapuleti ensimbi engagqwali aqine kakhulu anokumelana nokugqwala okuhle kakhulu, ukucutshungulwa kokugoba nokuqina kwesayithi lokushisela, nokusebenza okuhle kakhulu kwezitembu ezingxenyeni ezishiselwe. Ngokukhethekile, iqukethe u-C: 0.02% noma ngaphansi, N: 0.02% noma ngaphansi, Cr: 11% noma ngaphezulu nangaphansi kuka-17%, nokuqukethwe okufanele kuka-Si, Mn, P, S, Al, Ni, futhi kwanelisa u-12 ≤ Cr Mo 1.5Si ≤ 17, 1 ≤ Ni 30 (CN) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3Mo ≥ 16.0, 0.006 ≤ CN ≤ ku-0.05 ipuleti elingenasici ~ 050 insimbi engenasici kuya ku-2050 , bese kwenziwa ngo-1 ° C / s Ukwelashwa kokushisa okungenhla kokupholisa izinga lokupholisa. Ngakho-ke, kungaba isakhiwo esiqukethe i-martensite enengxenye yevolumu engu-12% noma ngaphezulu, amandla aphezulu angu-730 MPa noma ngaphezulu, ukumelana nokugqwala, ukugoba ukusebenza, kanye neshidi lensimbi engenasici elinamandla kakhulu endaweni ethinteke ukushisa kwe-weld. ubulukhuni. Ngokusebenzisa i-Mo, B, njll., indawo yokusebenza yabezindaba yengxenye eshiselwe ingathuthukiswa ngokuphawulekayo.

Ilangabi le-oxygen plus gas alikwazi ukusika insimbi engagqwali ngoba insimbi engagqwali ayifakwa i-oxidized kalula.
