Kunokwehluka okungu-3 phakathi kwensimbi engama-304 yensimbi engenasici kanye ne-auntenitic stainless
Okokuqala, izici zalokhu zihlukile:
1. Izici zensimbi engama-304 engenasici Ukumelana nokushisa okuphezulu kwe-800 ℃, kunezimpawu zokusebenza okuhle kokusebenza nobulukhuni obuphezulu.
2. Izici zensimbi engenacala: Ngaphezu kokumelana nokugqwala kwe-oxidizing acid medium, uma inezinhlobo ze-sulfuric, i-acetic acid, i-acetic acid, i-acectic acid, iqukethe i-TI ne-NI, ukumelana kwayo kokugqwala kwensimbi ingathuthukiswa kakhulu. Insimbi ephezulu ye-silicon auntenitic esingenacala inokumelana kahle nokugqwala kwe-nitric acid.
Okwesibili , ukusetshenziswa kwalokhu okubili kwehlukile:
1. Ukusetshenziswa kwensimbi engama-304 engagqwali: Ilungele ukucubungula ukudla, ukugcinwa nokuhamba. Unokucutshungulwa okuhle nokushaywa kwe-weldatiability. Ama-Plate Heat Exchangers, ama-Bellows, Imikhiqizo yasekhaya (isigaba 1 no-2 i-Tableware, amakhabethe, amapayipi angaphakathi, amapayipi amanzi, ama-boilers, amabhathi); Izingxenye ezizenzakalelayo (ama-windshield wipers, ama-muffler, imikhiqizo ebunjiwe), imishini yezokwelapha, izinto zokwakha, amakhemikhali, imboni yokudla, insimbi yokudla, i-njll.
2. Ukusetshenziswa kwensimbi ye-auntenitic engagqwali: Kusetshenziswa kabanzi embonini yomhlobiso embonini kanye nefenisha yomhlobiso kanye nemboni yezokwelapha. Ngenxa yezakhiwo eziphelele nezinhle ezinhle zensimbi ye-auntenitic, kusetshenziswe kabanzi kwizimboni ezahlukahlukene.
Okwesithathu, izigaba zombili zihlukile:
1. Ukuhlukaniswa kwensimbi engama-304 engenasici: Kunezigaba eziningi zepayipi lensimbi engama-304, owokuqala wepayipi elingenamibatha kanye nepayipi lensimbi elinomthungo, kanye nepayipi lesibili eliyisisekelo le-304 ipayipi lensimbi elingagqwali lezohambo. Okunye ukwahlukaniswa kweZinga Likazwelonke, Izinga elijwayelekile laseJapan, indinganiso yaseMelika nokunye.
2. Ukuhlukaniswa kwensimbi ye-auntenitic engagqwali Endabeni yokuqukethwe okuphansi kwe-C, okuqukethwe kwe-CR kungu-18% ~ 28%, futhi okuqukethwe kwe-NI kungu-3% ~ 10%. Amanye amansimbi aqukethe izinto ezengeziwe ezinjengeMo, CU, SI, NB, TI, NE-N.
Lolu hlobo lwensimbi lunezimpawu zensimbi ezingenasici ezingezinhle. Uma kuqhathaniswa ne-Ferrite, ine-plastiki yepulasitiki ephakeme nokuqina, akukho okushisa okushisa kwekamelo, futhi kuthuthukiswe kakhulu ukumelana nokuqina kokugqwala kanye nokusebenza kwe-welding.
Ngasikhathi sinye, futhi igcina ubucwebe obungu-475 ℃ kanye nokuvuselelwa okuphezulu okushisayo kwensimbi engenacala, futhi inezimpawu ze-superlulastity. Uma kuqhathaniswa nensimbi engenacala, inamandla aphezulu kanye nokuphikiswa okuthuthuke kakhulu ekugqwalisweni kwezinto zokugqwala kanye ne-chloride ukucindezela. Insimbi engenacala ye-Duplex inokuphikiswa okuhle kakhulu kokugqwala futhi inensimbi engenacala ye-nickel.
Khetha Hangao tech (seko mishini) Ukubhala okuphezulu kwensimbi eqinile yokukhiqiza ipayipi i-auntenitic tube mill ukuphatha ukukhiqizwa kwensimbi engenasici angama-304 namapayipi wensimbi engagqwali ngasikhathi sinye. Isakhiwo se-Archway kanye ne-roller beth elungiselelwe ukunciphisa i-shaft runout futhi ngcono kakhulu ukunemba kwepayipi lensimbi. Isigaba se-welding ekwakheni singasebenzisa futhi ibhokisi lokuvikelwa kwe-welding ye-welding ye-welding ukuze linciphise i-oxidation futhi sithole ikhwalithi ephezulu.
