4.904L Tsanangudzo:
1) Super austenitic Stainless simbi 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) iri
high alloy austenitic stainless simbi ine low carbon content.
Iyo ine yakanaka corrosion resistance mu dilute sulfuric acid uye yakanyatsogadzirirwa nharaunda
ine ngura yakaoma. Iyo ine yakakwira chromium yemukati uye yakakwana nickel yemukati. Kuwedzerwa kwemhangura kunoita kuti ive nayo
kusimba kweasidhi yakasimba, kunyanya kupikisa kwakanyanya kune chloride interstitial corrosion uye kusagadzikana ngura kuputika. Hazvisi nyore kuoneka
ngura makwapa nepakatsemuka. Kupokana kwayo negomba corrosion kuri nani zvishoma pane kwemamwe masimbi. Iyo ine yakanaka processability uye
weldability, uye inogona kushandiswa kumanikidza midziyo.
2) Metallographic chimiro che904L simbi isina tsvina:
904L ndeye zvachose austenitic chimiro. Kuenzaniswa neyakajairika austenitic simbi isina tsvina ine yakakwira molybdenum zvemukati,
904L ine mhedzisiro yakakosha pane ferrite uye α Kunaya kwechikamu hakunzwisisike.
a. Zvenyama uye zvemuchina:
Density: 8.0g/cm3. Kusimba kwesimba: σ b≥520Mpa. Elongation: δ ≥35%
Nekuti iyo kabhoni ye904L yakadzikira (yakanyanya 0.020%), hapazove nekunaya kwecarbide pasi pese.
kupisa kurapwa uye welding mamiriro. Izvi zvinobvisa njodzi ye intergranular corrosion mushure mekupisa kwekupisa uye welding.
Nekuda kwehuwandu hwehuwandu hwechromium, nickel uye molybdenum uye nekuwedzera kwemhangura, iyo 904L inogona kupfuudzwa kunyangwe mukuderedza.
nharaunda, senge sulfuric acid uye formic acid.
Iyo yakakwira nickel yemukati inoita kuti ive neiyo yakaderera corrosion mwero mumamiriro anoshanda. Muchikamu chepakati che 0 ~ 98% ye pure sulfuric acid,
tembiricha yekushandisa ye904L inogona kunge yakakwira se40 ℃. Iyo corrosion resistance ye pure phosphoric acid muhuwandu hwehuwandu hwe0 ~ 85% ndeye
kugona chose.
Muindasitiri phosphoric acid inogadzirwa nekunyorova maitiro, tsvina ine simba rakasimba pakuramba kwecorrosion. Pakati pemarudzi ose
yephosphoric acid, 904L ine nani kuonda kwekudzivirira pane yakajairwa simbi isina tsvina. Mune yakasimba oxidizing nitric acid, iyo corrosion resistance ye904L
yakaderera pane iyo yepamusoro yakasanganiswa simbi isina molybdenum. Mu hydrochloric acid, kushandiswa kwe904L kunogumira kune 1-2% yeiyo yakaderera.
Mune iyi concentration range. Iyo corrosion resistance ye904L iri nani pane yeyakajairika simbi isina tsvina. 904L simbi ine yakakwirira kuramba
kuora kwemavara.
Mumushonga wechloride, kupesana kwayo kwegorosi kwakaringana zvakare kwakanaka kwazvo. Iyo yakakwira nickel ye904L inoderedza kukora mumakomba nemakomba.
Kana tembiricha yeyakajairwa austenitic simbi isina simbi yakakwira kupfuura 60 ℃, inogona kunzwa kushushikana nekuora mune chloride yakapfuma.
zvakatipoteredza.
Uku kunzwa kunogona kuderedzwa nekuwedzera nickel yemukati yesimbi isina tsvina. Nekuda kweiyo yakakwira nickel yemukati, 904L ine yakanyanya kupikisa
stress corrosion cracking in chloride solution, concentrated hydroxide solution uye hydrogen sulfide rich environment.
Kutsigira welding zvinhu: welding tsvimbo (E385-16/17), welding waya (ER385).
b. Kuchengetedza kwekushandiswa kwe904L:
1. Processability
1.1 Welding kuita
Kufanana nesimbi yakajairwa isina tsvina, 904L inogona kuvezwa nenzira dzakasiyana siyana dzewelding. Iyo inonyanya kuzivikanwa nzira yewelding ndeye manual arc welding kana
inert gasi yakadzivirirwa welding.
Iyo electrode kana waya simbi inobva pakuumbwa kwesimbi yepasi uye ine kuchena kwepamusoro. Iyo molybdenum yemukati inodiwa kuve
yakakwirira kudarika simbi yepasi.
Preheating kazhinji haidiwe pamberi pewelding, asi mukutonhora kwekushanda kwekunze, kudzivirira kudzika kwemhute yemvura, majoini kana padyo.
nzvimbo dzinogona kudziyirwa zvakaenzana.
Iyo tembiricha yemuno haifanire kudarika 100 ℃ kudzivirira kabhoni kuunganidza uye intergranular corrosion. Simba diki remutsetse, rinoenderera
uye fast welding rate inofanirwa kutambirwa panguva yewelding.
Kazhinji, kurapwa kwekupisa hakudiwi mushure mekuputika. Kana kurapwa kwekupisa kuchidikanwa, kunofanirwa kupiswa kusvika 11000 ~ 1150 ℃ uye wozotonhodzwa nekukurumidza.
1.2 Machining kuita
Iwo machining maitiro e904L akafanana neaya emamwe austenitic simbi isina tsvina. Pane katsika kekunamatira chombo uye kushanda kuomesa panguva yekugadzirisa.
Maturusi eCarbide ane positive rake angle anofanira kushandiswa, uye oiri yakashambidzwa neklorini ichashandiswa sekucheka kunotonhorera. Zvishandiso uye maitiro zvichange zviri panzvimbo ye
kuderedza basa kuoma. Kunonoka kucheka kumhanya uye chiyero chekudya chinodziviswa panguva yekucheka.

* Scrubber uye fan mune organic acid kurapwa system.
* Chigadzirwa chekuchenesa mvura yegungwa, mvura yegungwa inopisa, midziyo yeindasitiri yemapepa, sulfuric acid uye nitric acid midziyo, kugadzira acid,
indasitiri yemishonga nemimwe michina yemakemikari, midziyo yekumanikidza, midziyo yechikafu.
* Fekitori yemishonga: centrifuge, reactor, nezvimwe.
*Chikafu chemuriwo: soy soso poto, waini yekubikira, hari yemunyu, midziyo nemapfekero.
* 904L isimbi inofananidzwa yekunyungudutsa sulfuric acid yakasimba inoparadza svikiro.
