DUPLEX ZOSAPANDA CHITSULO MTUNDU WA GREYIDI NDI MUYAMBO

•Lean Duplex SS – nickel yotsika komanso yopanda molybdenum – 2101, 2102, 2202, 2304
•Duplex SS – nickel ndi molybdenum yapamwamba – 2205, 2003, 2404
•Super Duplex – 25Chromium ndi nickel yapamwamba komanso molybdenum “plus” – 2507, 255 ndi Z100
•Hyper Duplex – More Cr, Ni, Mo ndi N – 2707

Katundu wa Makina:
• Zitsulo Zosapanga Dzimbiri za Duplex zili ndi mphamvu yochulukitsa kawiri kuposa mitundu ina ya austenitic.
•Izi zimathandiza opanga zida kugwiritsa ntchito zipangizo zoyezera zopyapyala popanga chombo!

Ubwino wa chitsulo chosapanga dzimbiri:
1. Poyerekeza ndi chitsulo chosapanga dzimbiri cha austenitic
1) Mphamvu ya kukolola ndi yoposa kawiri kuposa ya chitsulo chosapanga dzimbiri cha austenitic, ndipo ili ndi kulimba kokwanira kwa pulasitiki komwe kumafunika kuti ipangidwe. Kukhuthala kwa thanki kapena chotengera choponderezera chopangidwa ndi chitsulo chosapanga dzimbiri cha duplex ndi kotsika ndi 30-50% kuposa kwa chitsulo chosapanga dzimbiri cha austenitic chomwe chimagwiritsidwa ntchito kwambiri, zomwe zimathandiza kuchepetsa mtengo.
2) Imakhala ndi kukana bwino kwambiri ku stress corrosion cracking, makamaka m'malo okhala ndi ma chloride ions, ngakhale duplex alloy yokhala ndi alloy yochepa kwambiri imakhala ndi kukana kwakukulu ku stress corrosion cracking kuposa austenitic stainless steel. Stress corrosion ndi vuto lalikulu lomwe chitsulo chosapanga dzimbiri cha austenitic chimakhala chovuta kuthetsa.
3) Chitsulo chosapanga dzimbiri cha 2205 chomwe chimagwiritsidwa ntchito kwambiri m'zinthu zambiri chimakhala ndi kukana dzimbiri kuposa chitsulo chosapanga dzimbiri cha 316L austenitic, pomwe chitsulo chosapanga dzimbiri cha super duplex chimakhala ndi kukana dzimbiri kwambiri. Muzinthu zina, monga acetic acid ndi formic acid. Chimathanso kusintha zitsulo zosapanga dzimbiri za austenitic zokhala ndi alloy komanso ma alloy osagwira dzimbiri.
4) Ili ndi kukana bwino dzimbiri la m'deralo. Poyerekeza ndi chitsulo chosapanga dzimbiri cha austenitic chomwe chili ndi alloy yofanana, ili ndi kukana bwino kukalamba komanso kutopa ndi dzimbiri kuposa chitsulo chosapanga dzimbiri cha austenitic.
5) Chitsulo chosapanga dzimbiri cha austenitic chili ndi coefficient yochepa ya kukula kwa mzere ndipo chili pafupi ndi chitsulo cha kaboni. Ndi choyenera kulumikizidwa ndi chitsulo cha kaboni ndipo chili ndi kufunika kofunikira kwaukadaulo, monga kupanga mbale zophatikizika kapena zolumikizira.

2. Poyerekeza ndi chitsulo chosapanga dzimbiri cha ferritic, ubwino wa chitsulo chosapanga dzimbiri cha duplex ndi motere:
1) Kapangidwe ka makina kokwanira ndi kokwera kuposa ka chitsulo chosapanga dzimbiri cha ferritic, makamaka kulimba kwa pulasitiki. Sichimakhudzidwa kwambiri ndi kusweka ngati chitsulo chosapanga dzimbiri cha ferritic.
2) Kuwonjezera pa kukana dzimbiri, kukana dzimbiri kwina kwa m'deralo kuli bwino kuposa chitsulo chosapanga dzimbiri cha ferritic.
3) Kugwira ntchito kozizira komanso kugwira ntchito kozizira ndikwabwino kwambiri kuposa chitsulo chosapanga dzimbiri cha ferritic.
4) Kugwira ntchito kwa welding ndikwabwino kwambiri kuposa kwa chitsulo chosapanga dzimbiri cha ferritic. Kawirikawiri, palibe chithandizo cha kutentha chomwe chikufunika mutatenthetsa kale popanda welding.
5) Mtundu wa ntchito ndi wokulirapo kuposa wa chitsulo chosapanga dzimbiri cha ferritic.

Kugwiritsa ntchitoChifukwa cha mphamvu yayikulu ya chitsulo cha duplex, chimakonda kusunga zinthu, monga kuchepetsa makulidwe a khoma la chitoliro. Kugwiritsa ntchito SAF2205 ndi SAF2507W monga zitsanzo. SAF2205 ndi yoyenera kugwiritsidwa ntchito m'malo okhala ndi chlorine ndipo ndi yoyenera kugwiritsidwa ntchito m'malo oyeretsera kapena zinthu zina zosakanizidwa ndi chloride. SAF 2205 ndi yoyenera kugwiritsidwa ntchito makamaka m'malo osinthira kutentha okhala ndi chlorine yamadzi kapena madzi a brackish ngati malo ozizira. Zinthuzo ndizoyeneranso kugwiritsa ntchito njira zochepetsera sulfuric acid ndi ma organic acid oyera ndi zosakaniza zake. Monga: mapaipi amafuta mumakampani opanga mafuta ndi gasi: kuchotsa mchere wa mafuta osakonzedwa m'malo oyeretsera, kuyeretsa mpweya wokhala ndi sulfure, zida zoyeretsera madzi otayira; makina oziziritsira pogwiritsa ntchito madzi a brackish kapena njira zokhala ndi chlorine.

Kuyesa Zinthu:
SAKY STEEL imaonetsetsa kuti zipangizo zathu zonse zimayesedwa bwino tisanazitumize kwa makasitomala athu.

• Kuyesa kwa Makina Monga Kukanikiza Malo
• Mayeso a Kuuma
• Kusanthula Mankhwala - Kusanthula kwa Spectro
• Kuzindikira Zinthu Zabwino - Kuyesa kwa PMI
• Mayeso Ophwanyika
• Mayeso Ang'onoang'ono ndi MacroTest
• Mayeso Olimbana ndi Kupondaponda
• Kuyesa Kuyaka
• Kuyesa kwa Kutupa kwa Intergranular (IGC)
