Chitsulo chimagawidwa m'magulu anayi: zitsulo za carbon, Aloyi zitsulo, Zitsulo zosapanga dzimbiri Chida zitsulo
Mtundu 1-Zitsulo za carbon
Kupatula pa carbon ndi chitsulo, zitsulo za carbon zimakhala ndi zochepa chabe za zigawo zina.Zitsulo za kaboni ndizofala kwambiri pamagulu anayi azitsulo, zomwe zimapanga 90% ya kupanga zitsulo zonse!Chitsulo cha carbon chimagawidwa m'magulu atatu kutengera kuchuluka kwa mpweya muzitsulo:
l Zitsulo zotsika za carbon / zitsulo zofatsa (mpaka 0.3% carbon)
l Zitsulo zapakati pa carbon (0.3-0.6%)
l Zitsulo zapamwamba za carbon (zoposa 0.6% carbon)
Makampani nthawi zambiri amatulutsa zitsulozi mochuluka chifukwa ndizotsika mtengo komanso zolimba kuti zigwiritsidwe ntchito pomanga zazikulu.
Mtundu 2-Aloyi zitsulo
Zitsulo za aloyi zimapangidwa pophatikiza chitsulo ndi zinthu zina zowonjezera monga faifi tambala, mkuwa, chromium ndi/kapena aluminiyamu.Kuphatikiza zinthu izi kumapangitsa mphamvu, ductility, kukana dzimbiri ndi machinability chitsulo.
Mtundu 3-Zitsulo zosapanga dzimbiri
Makalasi azitsulo zosapanga dzimbiri amapangidwa ndi 10-20% chromium komanso faifi tambala, silicon, manganese, ndi kaboni.Chifukwa chakuchulukirachulukira kwawo kuti apulumuke nyengo yovuta, zitsulozi zimakhala zolimba kwambiri kuti zisamachite dzimbiri ndipo ndizotetezeka kuzigwiritsa ntchito pomanga panja.Makalasi azitsulo zosapanga dzimbiri amagwiritsidwanso ntchito kwambiri pazida zamagetsi.
Mwachitsanzo, zitsulo zosapanga dzimbiri 304 zimafunidwa kwambiri chifukwa chotha kupirira chilengedwe ndikusunga zida zamagetsi.
Ngakhale magiredi osapanga dzimbiri osiyanasiyana, kuphatikiza 304 zitsulo zosapanga dzimbiri, ali ndi malo mnyumba, zitsulo zosapanga dzimbiri zimafunidwa nthawi zambiri chifukwa cha ukhondo wake.Zitsulo izi zimapezeka kwambiri pazida zamankhwala, mapaipi, zotengera zokakamiza, zida zodulira ndi makina opangira chakudya.
Mtundu 4-Zida zachitsulo
Zitsulo za zida, monga momwe dzinalo likusonyezera, zimapambana pazida zodulira ndi kubowola.Kukhalapo kwa tungsten, molybdenum, cobalt ndi vanadium kumathandizira kupirira kutentha komanso kukhazikika kwanthawi zonse.Ndipo chifukwa amasunga mawonekedwe awo ngakhale atagwiritsidwa ntchito kwambiri, ndizomwe zimakondedwa pazida zambiri zamanja.
Zitsulo magulu
Pamwamba pa magulu anayiwo, zitsulo zithanso kugawidwa kutengera mitundu yosiyanasiyana kuphatikiza:
Kupanga: carbon range, aloyi, zosapanga dzimbiri, etc.
Kumaliza njira: otentha adagulung'undisa, ozizira adagulung'undisa, ozizira kumaliza, etc.
Njira yopanga: ng'anjo yamagetsi, kuponyera mosalekeza, etc.
Microstructure: ferritic, pearlitic, martensitic, etc.
Mphamvu zathupi: pamiyezo ya ASTM
Njira yochotsera oxidation: kuphedwa kapena kuphedwa pang'ono
Chithandizo cha kutentha: annealed, kupsya mtima, etc.
Nomenclature yapamwamba: khalidwe lamalonda, khalidwe la chotengera chokakamiza, khalidwe lojambula, etc.
Kodi kalasi yabwino kwambiri yachitsulo ndi iti?
Palibe kalasi "yabwino" yachitsulo yapadziko lonse lapansi, chifukwa chitsulo choyenera kwambiri pakugwiritsa ntchito chimadalira zinthu zambiri, monga momwe angagwiritsire ntchito, zofunikira zamakina ndi thupi, komanso malire azachuma.
Magiredi achitsulo omwe amagwiritsidwa ntchito pafupipafupi komanso omwe amawonedwa ngati apamwamba kwambiri pamtundu uliwonse ndi awa:
Zitsulo za Carbon: A36, A529, A572, 1020, 1045, ndi 4130
Aloyi zitsulo: 4140, 4150, 4340, 9310, ndi 52100
Zitsulo zosapanga dzimbiri: 304, 316, 410, ndi 420
Zida zida: D2, H13, ndi M2
JINDALAI ndi gulu lotsogola lazitsulo lomwe limatha kupereka zitsulo zonse mu koyilo, pepala, chitoliro, chubu, ndodo, mipiringidzo, ma flanges, zigono, ma tee, ndi zina. Perekani Jindalai kukhulupirirana, ndipo mudzakhutitsidwa ndi mankhwalawa.
