Ngokuvamile, i-VJ Piping yenziwe ngensimbi engagqwali okuhlanganisa i-304, 304L, 316 kanye ne-316Letc. Lapha sizokwethula kafushane izici zezinto ezahlukahlukene zensimbi engagqwali.
SS304
Ipayipi lensimbi engagqwali engu-304 likhiqizwa ngokuhambisana nezinga laseMelika le-ASTM lohlobo lwensimbi engagqwali.
Ipayipi lensimbi engagqwali elingu-304 lilingana nepayipi lethu lensimbi engagqwali elingu-0Cr19Ni9 (OCr18Ni9).
Ishubhu lensimbi engagqwali engu-304 njengensimbi engagqwali lisetshenziswa kakhulu emishini yokudla, imishini yamakhemikhali ejwayelekile, kanye nasembonini yamandla e-athomu.
Ipayipi lensimbi engagqwali elingu-304 liyipayipi lensimbi engagqwali elisetshenziswa kabanzi, lisetshenziswa kabanzi ekukhiqizeni imishini nezingxenye zokusebenza okuhle okuphelele (ukumelana nokugqwala nokwakheka kahle).
Ipayipi lensimbi engagqwali engu-304 liyinsimbi engagqwali esetshenziswa kakhulu, engashisi. Lisetshenziswa emishinini yokukhiqiza ukudla, imishini yamakhemikhali ejwayelekile, amandla enuzi, njll.
Imininingwane yokwakheka kwamakhemikhali eshubhu lensimbi engagqwali engu-304 C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.
Umehluko Wokusebenza Kwensimbi Engagqwali engu-304 kanye no-304L
I-304L imelana kakhulu nokugqwala, i-304L iqukethe ikhabhoni encane, i-304 iyinsimbi engagqwali esetshenziswa kabanzi, futhi isetshenziswa kabanzi ekukhiqizweni kwemishini nezingxenye ezidinga ukusebenza okuhle okuphelele (ukumelana nokugqwala nokwakheka kahle). I-304L iyinhlobonhlobo yensimbi engagqwali engu-304 enokuqukethwe okuphansi kwekhabhoni futhi isetshenziselwa ukusetshenziswa kokushisela. Okuqukethwe okuphansi kwekhabhoni kunciphisa imvula yama-carbide endaweni ethintekile ekushiseni eduze kwe-weld, okungaholela ekugqwaleni kwe-intergranular (ukuguguleka kokushisela) ensimbini engagqwali kwezinye izindawo.
I-304 isetshenziswa kabanzi, inokumelana okuhle nokugqwala, ukumelana nokushisa, amandla okushisa aphansi kanye nezakhiwo zemishini; Ukucubungula okuhle kokushisa, njengokunyathela nokugoba, ngaphandle kokwelashwa kokushisa, ukuqina kwento (akukho magnetic, kusetshenziswa izinga lokushisa -196℃ -800℃).
I-304L inokumelana okuhle kakhulu nokugqwala komngcele wokusanhlamvu ngemva kokushisela noma ukukhululeka ekucindezelekeni: ingagcina ukumelana okuhle kokugqwala ngisho nangaphandle kokwelashwa kokushisa, izinga lokushisa lokusebenza -196℃-800℃.
SS316
Insimbi engagqwali engu-316 nayo inezakhiwo ezinhle zokuguguleka kwe-chloride, ngakho-ke ivame ukusetshenziswa ezindaweni zasemanzini.
Ifektri yeshubhu yensimbi engagqwali engagqwali engagqwali
Ukumelana nokugqwala kungcono kunensimbi engagqwali engu-304, enqubweni yokukhiqizwa kwe-pulp nephepha kunokumelana okuhle nokugqwala.
Futhi insimbi engagqwali engu-316 nayo imelana nezimo zezimboni zasemanzini kanye nezomoya onamandla. Ukumelana nokushisa kuma-degrees angu-1600 ngaphansi kokusetshenziswa okungahleliwe kanye nama-degrees angu-1700 ngaphansi kokusetshenziswa okuqhubekayo, insimbi engagqwali engu-316 imelana nokushiswa okuhle.
Ebangeni lama-degree angu-800-1575, kungcono ukungasebenzisi insimbi engagqwali engu-316 njalo, kodwa ebangeni lokushisa elingaphandle kokusetshenziswa okuqhubekayo kwensimbi engagqwali engu-316, insimbi engagqwali inokumelana okuhle nokushisa.
Ukumelana nokusha kwe-carbide kwensimbi engagqwali engu-316 kungcono kunokwensimbi engagqwali engu-316 futhi kungasetshenziswa ebangeni lokushisa elingenhla.
Insimbi engagqwali engu-316 inokusebenza okuhle kokushisela. Ingashiselwa kusetshenziswa zonke izindlela zokushisela ezijwayelekile. Ukushisela kungasetshenziswa ngokusebenzisa induku yokugcwalisa insimbi engagqwali engu-316Cb, 316L noma 309CB noma ukushisela kwe-electrode. Ukuze kutholakale ukumelana okuhle kakhulu kokugqwala, ingxenye yokushisela yensimbi engagqwali engu-316 kufanele ishiswe ngemva kokushisela. Ukushisela ngemuva kokushisela akudingeki uma kusetshenziswa insimbi engagqwali engu-316L.
Ukusetshenziswa okuvamile: imishini ye-pulp nephepha, imishini yokudaya, imishini yokuthuthukisa amafilimu, amapayipi, kanye nezinto zangaphandle kwezakhiwo zasemadolobheni ezindaweni ezisogwini.
Insimbi Engagqwali Elwa Namagciwane
Ngokuthuthuka komnotho, insimbi engagqwali embonini yokudla, izinsizakalo zokupheka kanye nokusetshenziswa kokuphila komndeni kusabalala kakhulu, kunethemba lokuthi ngaphandle kwezitsha zasekhaya zensimbi engagqwali kanye nezitsha zokudla, zikhanya futhi zihlanzekile njengezici ezintsha, kodwa futhi zinomsebenzi omuhle kakhulu wokubulala amagciwane, umsebenzi wokubulala amagciwane.
Njengoba sonke sazi, ezinye izinsimbi, njengesiliva, ithusi, i-bismuth njalonjalo zinomphumela wokulwa namagciwane, obulala amagciwane, okuthiwa insimbi engagqwali elwa namagciwane, zisensimbini engagqwali ukuze zengeze inani elifanele lezinto ezinomphumela wokulwa namagciwane (njengethusi, isiliva), ukukhiqizwa kwensimbi ngemva kokwelashwa kokushisa okulwa namagciwane, ngokusebenza okuzinzile kokucubungula kanye nokusebenza okuhle kokulwa namagciwane.
Ithusi liyisici esibalulekile se-antibacterial, ukuthi kufanele wengeze malini akufanele nje ucabangele i-antibacterial properties, kodwa futhi uqinisekise izimfanelo ezinhle nezizinzile zokucubungula zensimbi. Inani elihle kakhulu lethusi liyahlukahluka ngezinhlobo zensimbi. Ukwakheka kwamakhemikhali kwensimbi engagqwali elwa namagciwane ethuthukiswe yi-Japanese Nissin Steel kuboniswe kuThebula 10. Ithusi elingu-1.5% lengezwa ensimbini ye-ferritic, elingu-3% ensimbini ye-martensitic kanye nelingu-3.8% ensimbini ye-austenitic.
