Duplex idafite ibyuma (DSS) ni ubwoko bwibyuma bidafite ikibazo birimo ibice bingana bya Ferrite na Austeteite, hamwe nigiciro gito muri rusange gikora byibuze 30%. DSS mubisanzwe ifite ibirimo bya chromium hagati ya 18% na 28% na nikel ikubiyemo hagati ya 3% na 10%. Imiyoboro imwe n'imwe ya duplex itagira ibyuma na my molybdenum (mo), umuringa (CU), Niobium (TI), na azote (n).
Iki cyiciro cyibyuma bihuza ibiranga ibyuma bya antenitike ndetse na Frurritic bidafite ingaruka. Ugereranije n'ibibero bidafite intege nke, DSS ifite plastike yo hejuru n'uburakari hejuru, ibura ubushyuhe bw'icyumba, kandi ikigaragaza uburyo bwo kurwanya ibicuruzwa bikomoka ku gaturwa no gukundwa. Muri icyo gihe, bigumana 475 ° C Brytiner hamwe nubuhanga buhanitse bwinyamanswa idafite impuhwe kandi byerekana ko superplictity. Ugereranije n'ibibero bidafite ibyuma, DSS ifite imbaraga nyinshi kandi nziza yo kurwanya imbaraga zo kurwanya imihangayiko na chloride imihangayiko. DSS nayo ifite ibyuma byiza byo kurwanya ruswa kandi ifatwa nkibyuma cya nikel-kuzigama.
Imiterere n'ubwoko
Kubera imiterere yacyo ebyiri za austenate na Ferrite, hamwe na buri cyiciro cyo kubara hafi ya kimwe cya kabiri, DSS igaragaza ibiranga ibiranga ANTusitike na Fruritique idafite ibyuma. Imbaraga zitanga za DSS ziva kuri 400 MPA zigera kuri 550 MPA, zikubye kabiri ibimera bisanzwe bidafite ishingiro. DSS ifite ubushyuhe bwinshi, ubushyuhe bwo hasi bwinzibacyuho, kandi bunoze cyane kurwanya ruswa no gusukura ugereranije nibumoso. Iragumana kandi imitungo ya Ferritique, nka 475 ° C Ubuntu, Imyitwarire Yubushyuhe Hejuru, Ububiko buke bwo Kwagura Amajyaruguru, SuperPlastity, na Magnetism. Ugereranije n'ibiti bya atenitique, DSS ifite imbaraga nyinshi, cyane cyane imbaraga, kandi itezimbere kurwanya ipangura, guhangayikishwa no gutaka, no kunanirwa kwa gato.
DSS irashobora gushyirwa mubwoko bune bushingiye ku bigize imiti: cr18, cr23 (kubuntu), cr22, na cr25. Ubwoko bwa CR25 burashobora gukomeza kugabana muburyo busanzwe kandi super duplex idafite ikibazo. Muri ibyo, CR22 na CR25 bakunze gukoreshwa. Mu Bushinwa, umubare munini w'amanota ya DSS yemejwe muri Suwede, harimo n'ubwoko 30 (CR12), ubwoko bwa CR2204, ubwoko bwa CR22205, n'ubwoko bwa CR225507 (CR25).
Ubwoko bwa duplex idafite ibyuma
1. Ubwoko buke-bundi:Ahagarariwe na ST32304 (23CR-4NI-0.1N), iyi mbaraga ntabwo irimo molybdenum kandi ifite ibyuma birwanya umubare bihwanye (pren) ya 24-25. Irashobora gusimbuza Aisi 304 cyangwa 316 muguhangayikishwa no gusaba kwangwa.
2. Ubwoko buciriritse:Ahagarariwe na SEND803 (22cr-5Ni-3ni-3Mo-0.15N), hamwe na 32-33. Kurwanya kwangirika biri hagati ya Aisi 316L na 6% mo + n austenitique itagira ingaruka mbi.
3. Ubwoko bwa Alloy:Mubisanzwe birimo 25% cr hamwe na molybdenum na azote, rimwe na rimwe umuringa kandi utuje. Ahagarariwe na ST32550 (25CR-6Ni-3Mo-2Po-2CU-2CI-0.2N
4. Super Duplex idafite ibyuma:Harimo urwego rwo hejuru rwa Molybdenum na azote, bahagarariwe na S32750 (25cr-0.7MO-0.
Amanota ya duplex idafite ibyuma mu Bushinwa
Igipimo gishya cy'Ubushinwa GB / T 20878-2007 "Amanota y'icyuma kandi arwanya ubushyuhe" akubiyemo amanota menshi ya DSS, nka 14cr18Ni11Ni5Ni19NI2NO3Si2ti. Byongeye kandi, uzwi cyane 2205 duplex ibyuma bihuye nicyiciro cya 022cr23ni5mo3n.
Ibiranga Duplex idafite imbaraga
Kubera imiterere yacyo ebyiri, nukugenzura neza imiterere yimiti no gutunganya ubushyuhe, DSS ihuza ibyiza byibibabi bya ferritic na austenique. Izungura gukomera kwinshi no gukurura ibyuma bya antenitique n'imbaraga nyinshi na chloride imihangayiko irwanya imyanda irwanya ibimera bya Ferritique. Iyi mitungo yo hejuru yagize DSS itezimbere vuba nkibikoresho bisukuye kuva mu myaka ya za 1980, bimaze kugereranywa na Martinetike, anitique, na ferite idafite ingaruka. DSS ifite ibiranga bikurikira:
1. Chloride ishimangira kurwanya indwaraMolybdenum-irimo DSS yerekana ko irwanirwa ryiza kuri chloride ihangayikishijwe na karlorion ku rwego rwo hasi. Mugihe ibimera 18-8 bidafite gahunda bikunda kubabazwa na Strenain Stroshiene mubihe bitabogamye birimo chloride na hss sullorides hamwe nibisanzwe bya chloride na hydrogen sullorides, bigatuma bikwiranye nubushyuhe.
2. Ibyuma byo kurwanya ruswa:DSS ifite ibyuma byiza byo kurwanya ruswa. Hamwe no kurwanya ibyuma bimwe bihwanye (pre = cr% + 3.3mo% + 16N%), dss hamwe nibimera bya stainless bidafite ishingiro byerekana ibishoboka nkibi. Gutera Dass na Crevice kurwanya ruswa, cyane cyane muri chromium ndende, azote ikubiyemo ubwoko bwa Aisi 316l.
3. Umunaniro kandi wambare ihohoterwa rishingiye ku garomba:DSS ikora neza mubidukikije bimwe na bimwe byangirika, bigatuma bikwiranye na pompe, indangagaciro, nibindi bikoresho byamashanyarazi.
4. Ibintu bya mashini:DSS ifite imbaraga nyinshi nimbaraga zumunaniro, hamwe nimbaraga zitanga kabiri zingana na asuitique itagira iherezo. Mu bihugu bihwanye n'umuti, kurenge kwayo kugera kuri 25%, n'ubufatanye bwayo Apt Ak (V-noch) arenga 100 J.
5. Gusunika:DSS ifite ubushyuhe bwiza hamwe nuburyo buke bushyushye. Gutegana muri rusange ntibisabwa mbere yo gusudira, kandi kuvura ubushyuhe nyuma yisuku ntibyikenewe, bituma gusudira hamwe na 18-8 ibyuma bidafite impungenge cyangwa ibimera bya karubone.
6. Gukora bishyushye:Ubushyo- Hejuru-Chromium (25% cr) DSS iragoye gato kumurimo ushushe ariko irashobora kwezwa mumasahani, imiyoboro, ninsinga.
7. Gukora ubukonje:DSS igaragaza akazi kanini mugihe gikonje gikora kirenze imyaka 18-8 antenitique ibyuma bidafite ishingiro kubijyanye no guhindura mugihe cyumuyoboro hamwe na plaque.
8. Umuyoboro wubushyuhe no kwaguka:DSS ifite imikorere yubushyuhe burenze hamwe na coefficent yo kwagura ubushyuhe ugereranije nibibero bidafite isuku, bigatuma bikwiranye no gufata ibikoresho no kubyara amasahani. Nibyiza kandi ko ubushyuhe bwo guhanura TUBE, hamwe nubushyuhe bworoshye bwo guhanahana ubushyuhe kuruta ibimera bidafite ishingiro.
9. Umunyacyubahiro:DSS igumana imitekerereze ya cyuma-chromium ndende kandi idakwiriye gukoreshwa mubushyuhe hejuru ya 300 ° C. Hasi ya Chromium Ibirimo muri DSS, bidakunze kugaragara ni ibyiciro byubamye nkicyiciro cya Sigma.
Ibyiza Byabyaranye
Icyuma cyuzuye ni uruganda rukurikira rwa duplex idafite ibyuma, itanga ibicuruzwa byuzuye harimo imiyoboro, amasahani, utubari, ninsinga. Ibicuruzwa byacu byubahiriza amahame manini kandi ni iso, CE, na API byemewe. Turashobora kwakira igenzura ryabandi hamwe nubugenzuzi bwa nyuma, tubikeshejwe ubuziranenge bwo hejuru.
Ibicuruzwa bya Ducmit Duplex idafite ibyuma bitazwi kuri ibyabo:
Ibikoresho byibanze byibanze:Dukoresha ibikoresho byiza bya fatizo kugirango dukemure imikorere yibicuruzwa.
Tekinike yo gukora cyane:Ibikoresho byacu-byubukorikori hamwe nitsinda ryinararibonye bidushoboza kubyara ibyuma bidafite ishingiro hamwe nibikorwa byukuri bya chimique hamwe nubukanishi.
Ibisubizo byihariye:Dutanga ubunini butandukanye hamwe nibisobanuro kugirango duhuze ibyifuzo byihariye byabakiriya bacu.
Kugenzura ubuziranenge:Gahunda yo kugenzura ubuziranenge zidasanzwe zemeza ko ibicuruzwa byose byujuje ubuziranenge bwindashyikirwa.
Sivelong Single:Hamwe no kohereza ibicuruzwa hanze, ibikoresho byo mu buvumo duplix ibyuma bidafite ingaruka ku bakiriya ku isi, bushyigikira inganda zitandukanye n'ibikoresho byizewe kandi byizewe kandi byo hejuru.
Hitamo ibisebe byiza kubitekerezo byawe bya duplex idakeneye kandi bikagira ireme na serivisi bitagereranywa bidutandukanya mu nganda.
