4 Mitundu ya Zitsulo

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 magulu osiyanasiyana azitsulo zosapanga dzimbiri, 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 anayi, zitsulo zikhozanso kugawidwa kutengera mitundu yosiyanasiyana kuphatikizapo:

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.

Quality nomenclature: malonda khalidwe, kuthamanga chombo khalidwe, kujambula khalidwe, 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.
