15-7PH Izinto ezibonakalayo
I-15-7PH iyimvula elingana ne-austenitic eyenza lukhuni insimbi engagqwali enamandla amakhulu, ubulukhuni obuphezulu kanye nokumelana nokugqwala okuhle.Ukumelana nokugqwala sekukonke ekushiseni okuphethwe yi-TH 1050 nezimo ze-RH 950 kubi kakhulu kunezinsimbi ezingenasici eziqinile ezisekelwe ku-chromium ezisekelwe ku-400 uchungechunge, kodwa akufani nalolo lwezinsimbi ezingama-304 ezingenasici ezisekelwe ku-chromium-nickel.
I-PH15-7Mo (uhlobo 632) izinga likazwelonke 0Cr15Ni7Mo2Al, Japan SUS632, iyinsimbi ethuthukiswe ngokufaka esikhundleni u-2% we-chromium ngensimbi engu-0Cr17Ni7Al ngo-2% we-molybdenum.Izakhiwo zayo eziyisisekelo zifana nensimbi engu-0Cr17Ni7Al, kodwa ukusebenza okuphelele kungcono kunayo.Esimweni se-austenite, ingakwazi ukumelana nezinqubo ezihlukahlukene zokubumba nokushisela, bese amandla aphakeme kakhulu angatholakala ngemva kokwelashwa kokushisa;inamandla amahle kakhulu okushisa angaphansi kuka-550 ℃.Isetshenziselwa ukwenziwa kwezindiza izingxenye zesakhiwo ezinodonga oluncane, iziqukathi ezihlukahlukene, amapayipi, iziphethu, ulwelwesi lwama-valve, ama-shafts omkhumbi, ama-compressor discs, izingxenye ze-reactor, nemishini ehlukahlukene yamakhemikhali nezinye izingxenye zesakhiwo.
15-7PH Uhlelo Lokwelapha Ukushisa: Isifunda, TH1050 State, RH950 State, CH900 State Three Three Reat Treatment Systems
Isimo A: Ngemva kokwelashwa kwesisombululo ku-1050°C, ukupholisa amanzi noma ukupholisa umoya.Isakhiwo se-metallographic sibonakala nge-austenite.
Isimo se-TH1050: Ngemuva kokwelashwa kwesisombululo ku-1050 ° C, gcina ku-760 ° C± 15 ° C i-90min, umoya opholile, upholile ukuya ku-15 ° C noma izinga lokushisa ekamelweni ngaphakathi kwe-1h, gcina i-30min, bese ushisa ku-565 ° C± 10 °C, gcina imizuzu engu-90 emoyeni, owaziwa nangokuthi 565°C ukuguga.Isakhiwo se-metallographic sibonakala ngemvula eqinisa i-martensite.
Isimo se-RH950: Ngemva kokwelashwa kwesisombululo ku-1050 ° C, gcina ku-955 ° C± 15 ° C imizuzu engu-10, umoya opholile kuya ekamelweni lokushisa, upholile ku -73 ° C± 6 ° C phakathi kwamahora angu-24, gcina amahora angu-8, bese ushisa ku-510°C±6°C, gcina imizuzu engu-60 ekupholiseni komoya, Okwaziwa nangokuthi 510 ℃ ukuguga.Isakhiwo se-metallographic sibonakala ngemvula eqinisa i-martensite.
Isimo se-CH900: Ngemva kokwelashwa kwesisombululo ku-1050 ° C, ukugoqa okubandayo okunokuguqulwa okungu-60%, ukushisa ku-490 ° C ngama-60min, ukupholisa umoya ekamelweni lokushisa.Isakhiwo se-metallographic sibonakala ngemvula eqinisa i-martensite.

15-7PH Izindawo Zokusebenza Zezinto Ezibalulekile
(15-7PH) 0Cr15Ni7Mo2Al insimbi engagqwali isetshenziswa kabanzi embonini yamakhemikhali.Ngokuyinhloko isetshenziselwa ukukhiqiza iziqukathi ezihlukahlukene, amapayipi, iziphethu, ama-diaphragms, njll ngokumelana nokugqwala okuhle namandla aphezulu.Ukumelana nokugqwala kwayo kudlula okwensimbi engagqwali ye-martensitic, imvula ye-Martensitic eqinisa insimbi engagqwali kanye ne-maraging stainless steel.
Ama-diaphragm, amaphaneli ezinyosi ashiselwe naka brazed, ama-diaphragm endiza, iziphethu, izindandatho ezigcinayo.Yenza iziphethu.indilinga eshisayo.Izesekeli ze-Counter.Imimese yezokwelapha.ukumba uwoyela.
