15-7PH Qalabka Qalabka
15-7PH waa roobab semi-austenitic ah oo adkeynaya birta aan fiicnayn oo leh xoog sare, qallafsanaan sare iyo iska caabin daxalka wanaagsan.Guud ahaan iska caabinta daxalka ee kulaylka lagu daweeyay xaaladaha TH 1050 iyo RH 950 way ka sii xun yihiin kuwa caadiga ah ee birta adag ee adag ee taxanaha 400 ee chromium, laakiin uma fiicna kan chromium-nickel-ku-salaysan 304 birta-daawaha ah.
PH15-7Mo (nooca 632) heerka qaran 0Cr15Ni7Mo2Al, Japan SUS632, waa bir la sameeyay iyadoo lagu bedelay 2% chromium birta 0Cr17Ni7Al leh 2% molybdenum.Aasaaska aasaasiga ah waxay la mid yihiin birta 0Cr17Ni7Al, laakiin waxqabadka guud ayaa ka fiican.Xaaladda Austenite, waxay u adkeysan kartaa qaabab kala duwan oo qaboojin ah iyo hababka alxanka, ka dibna xoogga ugu sarreeya ayaa la heli karaa ka dib daaweynta kulaylka;waxay leedahay awood heerkul sare oo aad u fiican oo ka hooseeya 550 ℃.Waxaa loo isticmaalaa soo saarista duulista qaybo qaab-dhismeed dhuuban, weelal kala duwan, tuubooyinka, ilo, xuubabka valve, shafka markabka, saxanadaha kombaresarada, qaybaha reactor, iyo qalab kala duwan oo kiimiko ah iyo qaybo kale oo dhismo ah.
15-7PH Nidaamka Daawaynta Kulaylka: Gobolka, TH1050 Gobolka, Gobolka RH950, CH900 Gobolka Saddexda Nidaam ee Daaweynta Kulaylka
Gobolka A: Ka dib daaweynta xalka 1050C, qaboojinta biyaha ama qaboojinta hawada.Qaab dhismeedka biraha waxaa lagu gartaa austenite.
Gobolka TH1050: Ka dib daaweynta xalka 1050 ° C, ku hay 760 ° C ± 15 ° C 90min, hawo qabow, qabow ilaa 15 ° C ama heerkulka qolka gudaha 1h, hayso 30min, ka dibna kulayl 565 ° C ± 10 °C, ku hay hawada 90min, sidoo kale loo yaqaan 565°C gabowga.Qaab dhismeedka biraha waxaa lagu gartaa roobka oo adkeeya martensite.
Gobolka RH950: Ka dib daaweynta xalka 1050 ° C, ku hay 955 ° C ± 15 ° C 10 daqiiqo, hawo qabow heerkulka qolka, qabow ilaa -73 ° C ± 6 ° C 24 saacadood gudahood, hayso saacadaha 8, ka dibna kuleyl ilaa 510C±6°C, ku hay 60 daqiiqo qaboojinta hawada, Sidoo kale loo yaqaan 510 ℃ gabow.Qaab dhismeedka biraha waxaa lagu gartaa roobka oo adkeeya martensite.
Gobolka CH900: Daawaynta xalka ka dib 1050°C, rogan qabow oo leh 60% qallafsanaan, kuleyl ilaa 490°C 60min, qaboojin hawo heerkul ah qolka.Qaab dhismeedka biraha waxaa lagu gartaa roobka oo adkeeya martensite.
