Abashinwa babigize umwuga 6 Umuyoboro wibyuma - 904L umuyoboro wicyuma - Huaxin

1. Ibisobanuro byoroshye:

904L super austenitis ibyuma bitagira umuyonga ni karubone nkeya, nikel ndende, molybdenum austenitike idafite ibyuma birwanya aside.

Urwego rwa GB: 00Cr20Ni25Mo4.5Cu

Icyiciro mpuzamahanga: 904L

Icyiciro gisanzwe cyabanyamerika: UNS ： N08904

Icyiciro cya EN: 1.4539

Ingano yubunini: 10 * 2mm kugeza 219 * 15mm cyangwa kugenwa ukurikije icyifuzo cyabakiriya

Uburebure: 300mm kugeza 20000mm

2. Ibigize imiti:

3. Ibikoresho bya mashini:

4.904L Ibisobanuro ：

1) Icyuma cya super austenitike idafite ibyuma 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) ni

umusemburo muremure austenitike udafite umwandaibyuma birimo karubone nkeya.

Ifite ruswa irwanya ruswa ya acide sulfurike kandi yagenewe ibidukikije

hamwe nikibazo gikomeye cyo kwangirika. Ifite chromium nyinshi nibirimo nikel ihagije. Kwiyongera k'umuringa bituma bigira

irwanya aside ikomeye, cyane cyane irwanya cyane chloride interstitial posion hamwe no guturika kwangirika. Ntibyoroshye kugaragara

ibibara byangirika. Kurwanya kwangirika kwayo ni byiza gato ugereranije nibindi byuma. Ifite uburyo bwiza kandi

gusudira, kandi irashobora gukoreshwa kumitsi.

2) Imiterere yicyuma cya 904L ibyuma bidafite ingese:

904L ni imiterere ya austenitis rwose. Ugereranije nicyuma gisanzwe cya austenitis kitagira ibyuma birimo molybdenum nyinshi,

904L igira ingaruka zikomeye kuri ferrite na α Imvura yicyiciro ntabwo yunvikana.

a. Imiterere yumubiri nubukanishi:

Ubucucike: 8.0g / cm3. Imbaraga zingana: σ b≥520Mpa ong Kurambura: δ ≥35% resistance Kurwanya ruswa ya 904L ibyuma bitagira umwanda:

Kuberako karubone ya 904L iri hasi cyane (ntarengwa 0.020%), ntihazabaho imvura ya karbide muri rusange

gutunganya ubushyuhe nuburyo bwo gusudira. Ibi bikuraho ibyago byo kwangirika hagati yimiti nyuma yo kuvura ubushyuhe rusange no gusudira.

Kubera ibintu byinshi bya chromium, nikel na molybdenum no kongeramo umuringa, 904L irashobora gutwarwa no mukugabanya

ibidukikije, nka acide sulfurike na aside aside.

Ibintu byinshi bya nikel bituma bigira igipimo gito cyo kwangirika muri leta ikora. Mubipimo bya 0 ~ 98% bya acide sulfurike nziza,

gukoresha ubushyuhe bwa 904L birashobora kuba hejuru ya 40 ℃. Kurwanya ruswa ya acide fosifori yuzuye murwego rwo hagati ya 0 ~ 85% ni

byiza cyane.

Muri acide fosifori yinganda ikorwa nuburyo butose, umwanda ugira ingaruka zikomeye mukurwanya ruswa. Mu bwoko bwose

ya aside ya fosifori, 904L ifite imbaraga zo kurwanya ruswa kurusha ibyuma bisanzwe bidafite ingese. Muri aside irike ikomeye ya aside nitricike, irwanya ruswa ya 904L

ni munsi yicyuma kinini kivanze nta molybdenum. Muri aside hydrochloric, gukoresha 904L bigarukira kuri 1-2% yibitekerezo byo hasi.

Muri uru rwego. Kurwanya ruswa ya 904L nibyiza kuruta ibyuma bisanzwe bidafite ingese. 904L ibyuma bifite imbaraga zo guhangana na

Kubora.

Mubisubizo bya chloride, kurwanya kwangirika kwayo nabyo ni byiza cyane. Nikel nyinshi iri muri 904L igabanya igipimo cya ruswa mu myobo no mu myobo.

Iyo ubushyuhe bwibyuma bisanzwe bya austenitike bidafite ibyuma birenga 60 ℃, birashobora kuba byoroshye kwangirika kwinshi muri chloride ikungahaye

ibidukikije.

Iyi sensitivite irashobora kugabanuka mukongera nikel yibikoresho byicyuma. Bitewe na nikel nyinshi, 904L ifite imbaraga zo kurwanya

guhangayika kwangirika kumuti wa chloride, hydroxide yibanze hamwe na hydrogen sulfide ibidukikije bikungahaye.

Gushyigikira ibikoresho byo gusudira: inkoni yo gusudira (E385-16 / 17), insinga yo gusudira (ER385).

b. Icyitonderwa cyo gusaba 904L:

1. Ibikorwa

1.1 Imikorere yo gusudira

Kimwe nicyuma gisanzwe kitagira umwanda, 904L irashobora gusudwa nuburyo butandukanye bwo gusudira. Uburyo busanzwe bwo gusudira ni intoki arc gusudira cyangwa

inert gaze ikingira gusudira.

Icyuma cya electrode cyangwa insinga gishingiye ku bigize icyuma fatizo kandi gifite ubuziranenge bwinshi. Ibirimo molybdenum birasabwa kuba

hejuru yicyuma fatizo.

Ubushuhe ntibusanzwe mbere yo gusudira, ariko mugikorwa cyo hanze gikonje, kugirango wirinde guhumeka imyuka y'amazi, ingingo cyangwa yegeranye

uturere dushobora gushyuha neza.

Ubushyuhe bwaho ntibushobora kurenga 100 ℃ kugirango wirinde kwirundanya kwa karubone no kwangirika hagati. Ingufu ntoya y'umurongo, ikomeza

kandi umuvuduko wo gusudira byihuse ugomba gukoreshwa mugihe cyo gusudira.

Mubisanzwe, kuvura ubushyuhe ntibisabwa nyuma yo gusudira. Niba hakenewe kuvura ubushyuhe, bigomba gushyuha kugeza 11000 ～ 1150 ℃ hanyuma bigakonja vuba.

1.2 Imikorere

Ibiranga imashini biranga 904L birasa nibindi byuma bya austenitis. Hariho imyumvire yo gufata ibikoresho no gukomera mugihe cyo gutunganya.

Ibikoresho bya Carbide bifite inguni nziza ya rake bigomba gukoreshwa, kandi amavuta ya sulfure na chlorine azakoreshwa mugukata gukonjesha. Ibikoresho nibikorwa bigomba kuba mbere ya

kugabanya akazi gakomeye. Kwihuta kugabanya umuvuduko nigaburo ryibiryo bigomba kwirindwa mugihe cyo gukata.

5. Umusaruro ujyanye:

6. Ubundi buvuzi

1) Igipolonye

2) Ikimenyetso:

7. Gupakira no gupakira:

8. Gusaba:

904L ikoreshwa mubice bikurikira:

* Ibikoresho bya peteroli na peteroli, nkibisubizo mubikoresho bya peteroli.

* Ibikoresho byo kubika no gutwara ibintu bya acide sulfurike, nko guhinduranya ubushyuhe.

* Igikoresho cya flue gazi ya desulfurizasi yinganda zikoreshwa cyane cyane mumubiri winjiza, flue, shutter, imbere, sisitemu yo gutera, nibindi.

* Scrubber numufana muri sisitemu yo kuvura aside.

* Uruganda rutunganya amazi yo mu nyanja, guhinduranya amazi yo mu nyanja, ibikoresho byinganda zimpapuro, aside sulfurike nibikoresho bya aside nitike, gukora aside,

uruganda rwa farumasi nibindi bikoresho bya shimi, ibikoresho byumuvuduko, ibikoresho byibiribwa.

* Uruganda rwa farumasi: centrifuge, reaction, nibindi

* Ibiryo by'imboga: inkono ya soya, vino yo guteka, inkono y'umunyu, ibikoresho no kwambara.

* 904L nicyuma gihuye na acide sulfurike acide ikomeye yangirika.
