Luhlobo oluhle kakhulu kwizicelo kwi-petrochemical, imichiza, kunye nemveliso yokuphatha ubushushu, kunye namacandelo omthanga kunye nolunye usetyenziso lweqondo lokushisa. Iplate yentsimbi engama-310s i-staight lilitlet, iphepha elincinci elenziwe kule alloy ethile.
3.I-253Ma (S30815) ipleyiti yentsimbi engenasitayile
Iimpawu: I-253ma lilitye elixhaphakileyo elixhaphakileyo elixhaphakileyo elenzelwe izicelo ezifuna amandla aphezulu afuna amandla aphezulu kunye nokunganyangeki okuhle. Uluhlu lobushushu olusebenzayo luyi-850-1100 ℃.
I-253ma luhlobo oluthile lwe-alloight yentsimbi engenasitayile eyilelwe ukuba kusetyenziswe amaqondo obushushu amaqondo obushushu. Inika ukumelana nokugqwesa kwi-oxidation, i-sulfidation, kunye ne-carburiting kumaqondo obushushu aphakamileyo. Oku kwenza ukuba ilungele ukusetyenziswa kumashishini ahlukeneyo, kubandakanywa nezo zibandakanya ubushushu kunye nokusula, ezinjengeendawo zokuvelisa amandla, kunye namacandelo anemizi-mveliso.Amaphepha angama-253mma ngamaqhekeza anqabileyo, amaflethi ezinto ezenziwe kolu labelo. Zisetyenziswa kwizicelo ezahlukeneyo apho indibaniselwano yokunganyangeki kobushushu kunye nokuxhaphaza ubutyebi kubalulekile. Amaphepha anokuncitshiswa kwaye alwenziwe kwiimilo ezahlukeneyo ukufezekisa iimfuno ezithile zeprojekthi.

I-253ma Plation Ukunganyangeki kokungakhathali kunye nokuhlala okuphambili kokusetyenziswa:
1. Ukuchasana nokuchasana kwecodion: 253MA uqhayisa ngokuchasene ne-oxidation egqwesileyo, ukumelana nobushushu obungaphezulu kwamaqondo obushushu, kunye namandla aphezulu okusasaza amaqondo obushushu. Kusebenza ngakumbi kuluhlu lobushushu lwe-850 ukuya kwi-1100 ° C.
2. Uluhlu lweProtetrorar Kwiqondo lobushushu phakathi kwe-600 ne-3500 ° C, iinguqu zesakhiwo, zikhokelela ekunciphiseni ubunzima begumbi.
Amandla e-3.mbeka ahlumayo: Olu laley luphelisa izitho ezi-7 ezingenanto, ezinje nge-304 ne-310s, ngokwamandla amafutshane amafutshane kubushushu obahlukeneyo nge-20%.
4.Ubumbeko lwe-SCHICAL: 253MA bonakalisa ubume bekhemikhali obulinganayo obunika umsebenzi okhethekileyo kuluhlu lobushushu lwe-850-15 ° C. Ibonisa kakhulu ukunganyangeki okuphezulu kwe-oxidation, amaqondo obushushu ukuya kuthi ga kwi-1150 ° C. Ikwabonelela ngokuchaseneyo nokuchasana okuphezulu kunye nokuqhekeka kwamandla.
5.Coriyasion Ukuxhathisa: Ukongeza kubuchule bayo obunobushushu, i-253ma ibonisa ukumelana nobushushu obuphakathi kunye nokuhlaselwa kweemeko zegesi.
6.strentrent: Iphethe amandla aphezulu esivelisi kunye namandla amathole kumaqondo obushushu aphakamileyo.
