Ukubuka konke kwensimbi engenacala

Insimbi Engagqwali Engagqwali ihlukaniswe kusuka kumabanga ajwayelekile e-Dumplex ngezakhiwo zayo ezithuthukiswe kakhulu zokulwa nokuqinisekiswa. Kuyinto eyenziwe nge-adwoyed ebodwa ngokugxila okuphakanyisiwe kwezinto ezilwa nama-condrosive ezifana ne-chromium (CR) ne-molybdenum (mo). Ibanga lensimbi eliyisisekelo le-Super Dumplex elingenacala, i-S32750, liqukethe ama-chromium angama-28.0%, ama-3.5% molybdenum, kanye ne-8.0% nickel (NI). Lezi zingxenye zidlulisela ukumelana okuhlukile kuma-ejenti asolisayo, kufaka phakathi ama-acid, ama-chlorides, kanye nezixazululo ze-caustic.

Ngokuvamile, ama-Super Dumplex Steel angenacala akha phezu kwezinzuzo ezisunguliwe zama-duplex amamaki ngokuthuthuka kwamakhemikhali. Lokhu kwenza kube yibanga elihle lokuqamba izingxenye ezibucayi emkhakheni we-petrochemical, njengokushintshaniswa kokushisa, ama-boilers, kanye nemishini yokufakelwa kwengcindezi.

Ukuhlukaniswa kwensimbi engenacala

l Uhlobo lokuqala luhlobo lwe-alloy oluphansi, nebanga elimele le-ex s32304 (23cr-4ni-0.1n). Insimbi ayinayo i-molybdenum, futhi inani le-pren lingu-24-25. Ingasetshenziswa esikhundleni se-aisi304 noma 316 ekuphikiseni kokugqwayiza kwengcindezelo.

l Uhlobo lwesibili lungelohlobo lwe-aroy oluphakathi, i-brand emele ayina-s31803 (22cr-5ni-3mo-0.15n), inani le-pren liphakathi kwe-aisi 326l kanye ne-6% mo auntenitic insimbi engenacala.

l Uhlobo lwesithathu luhlobo lwe-alloy oluphakeme, oluvame ukuqukethe u-25% CR, i-molybdenum ne-nitrogen, kanti abanye nabo baqukethe ithusi neTungsten. Ibanga elijwayelekile elikhohlisiwe

l Uhlobo lwesine luyinsimbi enkulu yensimbi engenacala, equkethe i-molybdenum ephezulu ne-nitrogen. Ibanga elijwayelekile alina-S32750 (25cr-7Ni-3.7mo-0.3n), kanti abanye baqukethe amaTungstern ne-Copper. Inani le-pren likhulu kune-40, elingasetshenziswa ezimeni eziphakathi eziphakathi. Inokumelana kahle nokugqwayiza kanye nezakhiwo eziphelele zemishini, ezingaqhathaniswa nensimbi e-supen auntenitic engagqwali.

Izinzuzo zensimbi engenacala

Njengoba kushiwo ngenhla, i-Duplex imvamisa yenza kangcono kunezinhlobo zensimbi yomuntu ngamunye ezitholakala ngaphakathi kwe-miscructure yayo. Kungcono ukusho, inhlanganisela yezimpawu ezinhle ezivela ezintweni ze-Auucenite naseFerrite ihlinzeka ngesisombululo esingcono senani elikhulu lezimo ezahlukahlukene zokukhiqiza.

L Anti-Complosive Properties - umphumela we-molybdenum, i-chromium, kanye ne-nitrogen ekumelaneni nokugqwala kwe-duplex alloys enkulu. Ama-alloys ambalwa we-Dumplex angafanisa futhi adlule ukusebenza okulwa nokulwa namabanga adumile auntenitic afaka 304 no-316. Basebenza kahle ngokulwa ne-crevice kanye nokugqwala okukhonkotha.

l Ukuqhekeka kokugqwayiza kwengcindezelo - I-SSC iza ngenxa yezici eziningi zomoya asemkhathini - izinga lokushisa kanye nomswakama ukuba obonakale kunabo bonke. Ukuxineka okuthe xaxa kumane nje kunezela enkingeni. Amamaki ajwayelekile we-auntenitic athambekele kakhulu ekuqhekekeni kwengcindezelo kokuqhekeka - insimbi engenacala ye-duplex ayikho.

l Ubunzima - I-Duplex iqinile kunama-Ferritic Steel - ngisho nasemazingeni okushisa aphansi ngenkathi kungafani nokwenza umsebenzi wamabanga we-auntenitic kulesi sici.

l Amandla - Ama-Alloys weDuplex angaba izikhathi ezi-2 ezinamandla kunezakhiwo zombili ze-auntenitic nezenhlalo. Amandla aphezulu asho ukuthi insimbi ihlala iqinile ngisho nangobukhulu obuncishisiwe ababaluleke kakhulu ekunciphiseni amazinga wesisindo.
