Kuyambira kapangidwe kake mpaka mawonekedwe ake, zinthu zosiyanasiyana zimakhudza mawonekedwe a zinthu zopangidwa ndi chitsulo chosapanga dzimbiri. Chimodzi mwazinthu zofunika kwambiri kuganizira ndi mtundu wa chitsulo chomwe muyenera kugwiritsa ntchito. Izi zidzatsimikizira mawonekedwe osiyanasiyana, komanso mtengo wake komanso nthawi yomwe zinthu zopangidwa ndi chitsulo chosapanga dzimbiri zidzakhalire.
Ndiye mumadziwa bwanji komwe mungayambire?
Ngakhale kuti pulogalamu iliyonse ndi yapadera, mafunso 7 awa akuwonetsa mfundo zofunika kwambiri kuti zikuthandizeni kuchepetsa zomwe mungasankhe ndikupeza magiredi oyenera zosowa zanu kapena pulogalamu yanu.
1. Kodi CHITSULO CHANGU CHIMENE CHIKUFUNIKA KULIMBIKITSA MTUNDU WANJI?
Mukamaganizira za chitsulo chosapanga dzimbiri, zinthu zoyamba zomwe zimabwera m'maganizo mwina ndi kukana ma acid ndi ma chloride -- monga omwe amapezeka m'mafakitale kapena m'malo a m'nyanja. Komabe, kukana kutentha ndi chinthu chofunikira kuganizira.
Ngati mukufuna kukana dzimbiri, muyenera kupewa zitsulo za ferritic ndi martensitic. Mitundu yabwino kwambiri ya zitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito powononga ndi monga austenitic kapena duplex alloys monga magiredi 304, 304L, 316, 316L, 2205, ndi 904L.
Pa malo otentha kwambiri, magiredi a austenitic nthawi zambiri amakhala abwino kwambiri. Kupeza giredi yokhala ndi chromium yambiri, silicon, nayitrogeni, ndi zinthu zapadziko lapansi zosowa kwambiri kudzasintha kwambiri luso la chitsulocho kupirira kutentha kwambiri. Magiredi wamba pa malo otentha kwambiri ndi awa: 310, S30815, ndi 446.
Magiredi achitsulo a Austenitic ndi abwino kwambiri m'malo otentha pang'ono kapena oundana. Kuti mupeze kukana kowonjezereka, mutha kuyang'ana magiredi otsika a kaboni kapena nayitrogeni wambiri. Magiredi wamba m'malo otentha pang'ono ndi awa: 304, 304LN, 310, 316, ndi 904L.
2. KODI CHITSULO CHANGU CHIYENERA KUKHALA CHOPANGIDWA?
Chitsulo chomwe sichimapangidwa bwino chimatha kusweka ngati chigwiritsidwa ntchito mopitirira muyeso ndipo sichigwira ntchito bwino. Nthawi zambiri, zitsulo za martensitic sizikulimbikitsidwa. Kuphatikiza apo, chitsulo chomwe sichimapangidwa bwino sichingasunge mawonekedwe ake ngati pakufunika kupanga zinthu zovuta kapena zovuta.
Mukasankha mtundu wa chitsulo, muyenera kuganizira mtundu womwe mukufuna kuti chiperekedwe. Kaya mukufuna ndodo, slabs, mipiringidzo kapena mapepala zidzachepetsa zosankha zanu. Mwachitsanzo, zitsulo za ferritic nthawi zambiri zimagulitsidwa m'mapepala, zitsulo za martensitic nthawi zambiri zimagulitsidwa m'mipiringidzo kapena slabs, ndipo zitsulo za austentic zimapezeka m'mitundu yosiyanasiyana. Mitundu ina yachitsulo yomwe ilipo m'mitundu yosiyanasiyana ndi monga 304, 316, 430, 2205, ndi 3CR12.
3. Kodi Chitsulo Changa Chidzafunika Kupanga Machining?
Kukonza makina nthawi zambiri si vuto. Komabe, kulimbitsa ntchito kungapangitse zotsatira zosayembekezereka. Kuwonjezera sulfure kungathandize kukonza makina koma kumachepetsa kupangika, kusinthasintha, komanso kukana dzimbiri.
Izi zimapangitsa kupeza mgwirizano pakati pa makina ndi kukana dzimbiri kukhala chinthu chofunikira kwambiri pakupanga zitsulo zosapanga dzimbiri zomwe zili ndi magawo ambiri. Kutengera zosowa zanu, magiredi 303, 416, 430, ndi 3CR12 amapereka mgwirizano wabwino woti muchepetse zina.
4. KODI NDIYENERA KUSONKHA CHITSULO CHANGU CHOSADZIPANGIDWA?
Kuwotcherera chitsulo chosapanga dzimbiri kungayambitse mavuto—kuphatikizapo kusweka kwa kutentha, kusweka kwa dzimbiri, ndi dzimbiri pakati pa granular—kutengera mtundu wa chitsulo chomwe chagwiritsidwa ntchito. Ngati mukufuna kuwotcherera chitsulo chanu chosapanga dzimbiri, ma alloy a austenitic ndi abwino kwambiri.
Ma carbon ochepa angathandize kwambiri pakuwotcherera pomwe zowonjezera, monga niobium, zimatha kulimbitsa ma alloy kuti apewe nkhawa za dzimbiri. Ma aluminium otchuka a chitsulo chosapanga dzimbiri chowotcherera ndi 304L, 316, 347, 430, 439 ndi 3CR12.
5. KODI MANKHWALA OTHANDIZA KUTENTHA AKUFUNIKA?
Ngati kugwiritsa ntchito kwanu kumafuna kutenthedwa, muyenera kuganizira momwe mitundu yosiyanasiyana ya chitsulo imayankhira. Makhalidwe omaliza a zitsulo zina amasiyana kwambiri asanayambe komanso atamaliza kutenthedwa.
Nthawi zambiri, zitsulo zolimbitsa martensitic ndi precipitation, monga 440C kapena 17-4 PH, zimapereka ntchito yabwino kwambiri zikatenthedwa. Zitsulo zambiri zosapanga dzimbiri za austenitic ndi ferritic sizilimba zikatenthedwa ndipo chifukwa chake si njira zabwino kwambiri.
6. Kodi ndi mphamvu yanji yachitsulo yomwe ndiyenera kugwiritsa ntchito?
Mphamvu yachitsulo ndi chinthu chofunikira kuganizira kuti chitetezo chikhale cholimba kwambiri. Komabe, kubweza ndalama mopitirira muyeso kungayambitse ndalama zosafunikira, kulemera, ndi zinthu zina zosafunikira. Makhalidwe a mphamvu amakhazikitsidwa mosasamala ndi banja la chitsulo ndipo mitundu ina imapezeka m'magiredi osiyanasiyana.
7. KODI NDI NDALAMA YABWINO KWAMBIRI NDIPONSO NDALAMA YA CHUMA ICHI YOTSATIRA MOYO WONSE WAKE MU CHIGANZO CHANGU?
Zonse zomwe takambirana kale zikugwirizana ndi funso lofunika kwambiri posankha mtundu wa chitsulo chosapanga dzimbiri—mtengo wake wonse. Mukagwirizanitsa mitundu ya chitsulo chosapanga dzimbiri ndi malo omwe mukufuna, momwe mungagwiritsire ntchito komanso zomwe mukufuna, mutha kutsimikizira kuti chikugwira ntchito bwino komanso kuti chikhale ndi phindu lalikulu.
Samalani kuti mufufuze momwe chitsulocho chidzagwirira ntchito panthawi yomwe mukufuna kugwiritsa ntchito komanso ndalama zomwe zingakhudzidwe pokonza kapena kusintha musanasankhe. Kuchepetsa ndalama zomwe zingawonongedwe pasadakhale kungayambitse ndalama zambiri pa ntchito yanu, chinthu, kapangidwe kake, kapena ntchito ina iliyonse.
Popeza pali mitundu yambiri ya zitsulo zosapanga dzimbiri zomwe zilipo, kukhala ndi katswiri woti akuthandizeni kuwunikira zosankha ndi zovuta zomwe zingachitike ndi njira yabwino kwambiri yotsimikizira kuti mukupeza phindu labwino kwambiri pakuyika ndalama muzitsulo zosapanga dzimbiri. Monga kampani yotsogola yogulitsa zitsulo zosapanga dzimbiri kwa zaka zoposa 20, Jindalai Steel Group idzagwiritsa ntchito zomwe takumana nazo kuti ikuthandizeni pogula zinthu. Onani mndandanda wathu waukulu wa zinthu zosapanga dzimbiri pa intaneti kapena imbani kuti mukambirane zosowa zanu ndi membala wa gulu lathu.
