Kuchokera pakupanga mpaka mawonekedwe, zinthu zingapo zimakhudza mawonekedwe azitsulo zosapanga dzimbiri.Chimodzi mwazinthu zofunika kwambiri ndizomwe zimagwiritsidwa ntchito ndi zitsulo.Izi zidzatsimikizira mikhalidwe yosiyanasiyana ndipo, pamapeto pake, zonse mtengo ndi moyo wazinthu zanu zachitsulo chosapanga dzimbiri.
Ndiye mumadziwa bwanji koyambira?
Ngakhale ntchito iliyonse ndi yapadera, mafunso 7wa amawunikira malingaliro ofunikira kuti akuthandizeni kuchepetsa zomwe mungasankhe ndikupeza magiredi omwe akuyenerana ndi zosowa zanu kapena ntchito yanu.
1. KODI ZINTHU ZANGA ZIKUFUNA KUKANIZWA KWAMBIRI KOTI?
Mukaganizira za chitsulo chosapanga dzimbiri, zinthu zoyamba zomwe zimabwera m'maganizo mwina ndi kukana ma asidi ndi ma chloride - monga zomwe zimapezeka m'mafakitale kapena malo am'madzi.Komabe, kukana kutentha ndikofunikanso kulingalira.
Ngati mukufuna kukana dzimbiri, muyenera kupewa zitsulo za ferritic ndi martensitic.Makalasi abwino kwambiri azitsulo zosapanga dzimbiri pamapangidwe owononga amaphatikiza ma austenitic kapena duplex alloys monga giredi 304, 304L, 316, 316L, 2205, ndi 904L.
Kwa malo otentha kwambiri, magiredi austenitic nthawi zambiri amakhala abwino kwambiri.Kupeza giredi yokhala ndi chromium yokwera, silicon, nayitrojeni, ndi zinthu zapadziko lapansi zomwe sizipezeka kawirikawiri kumasinthanso kuthekera kwachitsulo kupirira kutentha kwambiri.Magiredi wamba am'malo otentha kwambiri akuphatikizapo 310, S30815, ndi 446.
Magiredi achitsulo a Austenitic nawonso ndi abwino kwa malo otsika kapena okhala ndi cryogenic.Kuti muwonjezere kukana, mutha kuyang'ana magiredi otsika a carbon kapena apamwamba a nayitrogeni.Magiredi wamba a malo otsika kutentha akuphatikizapo 304, 304LN, 310, 316, ndi 904L.
2. KODI CHIYAMBI CHANGU CHIFUNA KUKHALA WOUMBIKA?
Chitsulo chokhala ndi mawonekedwe osawoneka bwino chimatha kukhala chosalimba ngati chikagwiritsidwa ntchito mopitilira muyeso ndikupereka magwiridwe antchito ochepa.Nthawi zambiri, zitsulo za martensitic sizovomerezeka.Kuphatikiza apo, chitsulo chokhala ndi mawonekedwe otsika sichingakhale ndi mawonekedwe ake pakafunika kupanga zovuta kapena zovuta.
Posankha kalasi yachitsulo, muyenera kuganizira mawonekedwe omwe mukufuna kuti aperekedwe.Kaya mukufuna ndodo, ma slabs, mipiringidzo kapena mapepala azichepetsa zomwe mungasankhe.Mwachitsanzo, zitsulo za ferritic nthawi zambiri zimagulitsidwa m'mapepala, zitsulo za martensitic zimagulitsidwa m'mipiringidzo kapena slabs, ndipo zitsulo za austentic zimapezeka mumitundu yambiri.Makalasi ena achitsulo omwe amapezeka m'mitundu yosiyanasiyana akuphatikizapo 304, 316, 430, 2205, ndi 3CR12.
3. KODI CHIZINDIKIRO CHANGU CHIDZAFUNIKA KUCHITA?
Machining nthawi zambiri si vuto.Komabe, kulimbikira ntchito kungabweretse zotsatira zosayembekezereka.Kuphatikiza kwa sulfure kumatha kusintha machinability koma kumachepetsa mawonekedwe, weldability ndi kukana dzimbiri.
Izi zimapangitsa kupeza bwino pakati pa machinability ndi kukana kwa dzimbiri kukhala chinthu chofunikira kwambiri pamachitidwe ambiri opanga zitsulo zosapanga dzimbiri.Kutengera zosowa zanu, magiredi 303, 416, 430, ndi 3CR12 amapereka njira yabwino yochepetsera zosankha.
4. KODI NDIFUNA KUWOTILIZA CHULUMWI LANGA?
Kuwotcherera chitsulo chosapanga dzimbiri kungayambitse mavuto-kuphatikiza kusweka kotentha, kusweka kwa dzimbiri, ndi dzimbiri la intergranular-kutengera mtundu wazitsulo zomwe zimagwiritsidwa ntchito.Ngati mukufuna kuwotcherera chitsulo chanu chosapanga dzimbiri, ma alloys austenitic ndi abwino.
Magawo otsika a carbon amatha kuthandizira kutenthetsa pomwe zowonjezera, monga niobium, zimatha kukhazikika ma alloys kuti apewe nkhawa za dzimbiri.Makalasi otchuka azitsulo zosapanga dzimbiri zowotcherera amaphatikiza 304L, 316, 347, 430, 439 ndi 3CR12.
5. KODI MANKHWALA A KUCHERETSA AMAFUNIKA?
Ngati ntchito yanu ikufuna chithandizo cha kutentha, muyenera kuganizira momwe zitsulo zosiyanasiyana zimayankhira.Makhalidwe omaliza a zitsulo zina amasiyana kwambiri musanayambe komanso pambuyo pa chithandizo cha kutentha.
Nthawi zambiri, zitsulo zowumitsa martensitic ndi mvula, monga 440C kapena 17-4 PH, zimapereka ntchito yabwino kwambiri ikatenthedwa.Zitsulo zambiri zosapanga dzimbiri za austenitic ndi ferritic sizingalimba zikatenthedwa zikatenthedwa chifukwa chake sizosankha zabwino.
6. KODI NDI MPHAMVU YOTANI YA CHITSULO ILI CHOBWINO KWA NTCHITO LANGA?
Mphamvu yachitsulo ndi chinthu chofunikira kuganizira kuti muwonjezere chitetezo.Komabe, kubweza ndalama mopambanitsa kungayambitse mtengo wosafunikira, kulemera kwake, ndi zinthu zina zowononga.Makhalidwe amphamvu amayikidwa momasuka ndi banja lachitsulo ndi zosiyana zina zomwe zimapezeka m'makalasi osiyanasiyana.
7. KODI NDI CHUMA CHIYANI CHOKHALA PAMODZI PAMOYO WANGA?
Malingaliro onse am'mbuyomu amadyetsa funso lofunika kwambiri posankha kalasi yachitsulo chosapanga dzimbiri-mtengo wamoyo wonse.Kufananiza magiredi achitsulo chosapanga dzimbiri ndi malo omwe mukufuna, kagwiritsidwe ntchito ndi zomwe mukufuna, mutha kuwonetsetsa kuti ntchito yayitali komanso yopindulitsa kwambiri.
Samalani kuti mufufuze momwe chitsulocho chidzagwiritsire ntchito panthawi yomwe mukufuna kugwiritsa ntchito komanso ndalama zomwe zingakhudzidwe pokonza kapena kusintha musanasankhe.Kuchepetsa mtengo wamtsogolo kungapangitse kuti muwononge ndalama zambiri pamoyo wanu wa polojekiti, malonda, kapangidwe, kapena ntchito ina.
Ndi kuchuluka kwa magiredi achitsulo chosapanga dzimbiri ndi mafomu omwe alipo, kukhala ndi katswiri wokuthandizani kuwunikira zosankha ndi misampha yomwe ingachitike ndi njira yabwino kwambiri yowonetsetsera kuti mukupeza phindu lokwanira pakugulitsa zitsulo zosapanga dzimbiri.Monga gulu lotsogola la zitsulo zosapanga dzimbiri kwa zaka zopitilira 20, Jindalai Steel Group ithandizira zomwe takumana nazo kuti zikuthandizireni pakugula.Onani mndandanda wathu wambiri wazopanga zosapanga dzimbiri pa intaneti kapena imbani kuti mukambirane zomwe mukufuna ndi membala wa gulu lathu.
