Insimbi engagqwali evamile engamelana nokushisa ngokuvamile ihlukaniswe ngezinhlobo ezintathu, i-309S, i-310S kanye ne-253MA, insimbi engamelana nokushisa ivame ukusetshenziswa ekwenziweni kwama-boiler, ama-turbine anomusi, izitofu zezimboni kanye nezindiza, i-petrochemical kanye neminye imikhakha yezimboni ezingxenyeni zokusebenza ezishisa kakhulu.
1.Ama-309s: ipuleti lensimbi engagqwali (OCr23Ni13)
Izici: Ingamelana nokushisa okuphindaphindiwe ngaphansi kuka-980 ℃, ngamandla aphezulu okushisa aphezulu, ukumelana nokushiswa kwe-oxidation kanye nokumelana ne-carburizing.
Ukusetshenziswa: izinto zesithando somlilo, zingasetshenziswa ukukhiqiza izingxenye zensimbi ezishisayo, okuqukethwe kwayo okuphezulu kwe-chromium kanye ne-nickel kuqinisekisa ukumelana okuhle kokugqwala kanye nokumelana nokugqwala.
Uma kuqhathaniswa ne-austenitic 304 alloy, inamandla kancane ekushiseni kwegumbi. Empilweni yangempela, ingashiswa ngokuphindaphindiwe ku-980 ° C ukuze iqhubeke isebenza kahle. 310s: (0Cr25Ni20) ipuleti lensimbi engagqwali.
2.Ama-310s: ipuleti lensimbi engagqwali (OCr25Ni20)
Izici: Insimbi engagqwali ye-austenitic ephezulu ene-chromium-nickel enezakhiwo ezinhle zomshini zokushisa okuphezulu kanye nokumelana okuhle nokugqwala kuma-oxidizing media. Ifanele ukukhiqizwa kwezingxenye ezahlukene zesithando somlilo, izinga lokushisa eliphakeme kakhulu lingu-1200 ℃, izinga lokushisa lokusetshenziswa okuqhubekayo lingu-1150 ℃.
Isicelo: impahla yesithando, impahla yedivayisi yokuhlanza imoto.
Insimbi engagqwali ye-310S iyi-alloy yensimbi engagqwali ye-austenitic engagqwali esetshenziswa ezindaweni ezahlukahlukene zokushisa okuphezulu nokugqwala. Kuyisinqumo esihle kakhulu sokusetshenziswa embonini ye-petrochemical, yamakhemikhali, kanye neyokwelapha ukushisa, kanye nezingxenye zesithando kanye nezinye izinhlelo zokusebenza zokushisa okuphezulu. Ipuleti lensimbi engagqwali ye-310S liyishidi eliyisicaba, elincane elenziwe ngale alloy ethile.
3.Ipuleti lensimbi engagqwali elingu-253MA (S30815)
Izici: I-253MA iyinsimbi engagqwali yase-Austenitic engangenisi ukushisa eyenzelwe izinhlelo zokusebenza ezidinga amandla aphezulu okukhukhuleka kanye nokumelana okuhle nokugqwala. Izinga layo lokushisa lokusebenza lingu-850-1100 ℃.
I-253MA uhlobo oluthile lwe-alloy yensimbi engagqwali eyenzelwe ukusetshenziswa kwezinga lokushisa eliphezulu. Inikeza ukumelana okuhle kakhulu ne-oxidation, sulfidation, kanye ne-carburization emazingeni okushisa aphezulu. Lokhu kuyenza ifaneleke ukusetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi lezo ezihilela ukushisa nokugqwala, njengemikhakha ye-petrochemical, ukukhiqizwa kwamandla, kanye ne-industrial furnace.Amashidi angu-253MA ayizingcezu ezincane, eziyisicaba zezinto ezenziwe ngale ngxubevange. Asetshenziswa ezinhlotsheni ezahlukene lapho ukuhlanganiswa kokumelana nokushisa okuphezulu kanye nokumelana nokugqwala kubalulekile khona. Amashidi anganqunywa futhi enziwe abe yizimo ezahlukene ukuze kuhlangatshezwane nezidingo ezithile zephrojekthi.
Amashidi angu-253MA, Amapuleti Ukwakheka Kwamakhemikhali
