Kodi pali kusiyana kotani pakati pa SS 304 ndi CRCA?

Mu gawo la metallurgy ndi engineering engineering, SS 304 ndi CRCA (Cold Rolled Close Annealed) zitsulo zimakhala ndi malo osiyana, chilichonse chimakhala ndi katundu wake ndi ntchito zake. M'nkhaniyi, tikufuna kupereka kufananitsa kokwanira komanso kovomerezeka pakati pa SS 304 ndi chitsulo cha CRCA, kuyang'ana kwambiri kapangidwe kake, katundu, ndi kagwiritsidwe ntchito kake.

Kodi pali kusiyana kotani pakati pa SS 304 ndi CRCA?

Choyamba, tiyeni tifufuze za kapangidwe ka SS 304. SS 304, yomwe imadziwikanso kuti SUS304 ku Japan kapena AISI 304 padziko lonse lapansi, ndi chitsulo chosapanga dzimbiri cha austenitic kalasi. Kapangidwe kake kake kamakhala ndi chitsulo, chromium, ndi nickel. Zomwe zili mu chromium nthawi zambiri zimachokera ku 18% mpaka 20%, pomwe nickel imakhala pafupifupi 8% mpaka 10.5%. Kuphatikizika kwa zinthu izi kumapatsa SS 304 kukana kwake kwa dzimbiri, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito mitundu ingapo pomwe kukhudzidwa ndi malo owononga ndikotheka. Kuphatikiza apo, SS 304 ilinso ndi kuchuluka kwa kaboni, manganese, silicon, phosphorous, sulfure, ndi nayitrogeni, zomwe zimawonjezera mphamvu zake zamakina ndi thupi.

Kumbali inayi, chitsulo cha CRCA ndi mtundu wa chitsulo cha kaboni chomwe chakonzedwa kudzera mukugudubuzika kozizira ndi kutseka kwa annealing. Kuzizira kozizira kumaphatikizapo kugubuduza chitsulo kutentha kwa chipinda kapena pansi, zomwe zimapangitsa kuti pamwamba pake pakhale kutha kwake komanso makina ake. Close annealing ndi njira yochizira kutentha yomwe imachotsa kupsinjika kwamkati ndikuwongolera kukhazikika kwachitsulo ndi kulimba kwake. Zomwe zimapangidwa ndi chitsulo cha CRCA zimakhala ndi chitsulo ndi kaboni, zomwe zimakhala ndi zinthu zina monga manganese, phosphorous, ndi sulfure kutengera kalasi yeniyeni.

Tsopano, tiyeni tipitirire kuzinthu za zida ziwirizi. SS 304 imadziwika chifukwa cha kukana bwino kwa dzimbiri, zomwe zimachitika chifukwa chopanga kagawo kakang'ono koteteza oxide pamwamba pake. Chosanjikiza ichi chimalepheretsa kuwonongeka kwina mwa kutsekereza kulumikizana pakati pa zitsulo ndi zowononga. SS 304 imawonetsanso bwino ductility, weldability, ndi mawonekedwe, kupangitsa kuti ikhale yosavuta kugwira nayo ntchito komanso yoyenera pazopanga zosiyanasiyana. Kuphatikiza apo, imakhala ndi kukana bwino kwa kutentha ndipo imatha kugwiritsidwa ntchito potentha kwambiri.

M'malo mwake, chitsulo cha CRCA chimadziwika chifukwa champhamvu komanso kuuma kwake. Kugubuduza kozizira kumawonjezera mphamvu zokolola zachitsulo ndi kulimba kwamphamvu, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kukhulupirika kwadongosolo. Kumangirira kwapafupi kumapangitsanso kuti chitsulocho chikhale cholimba komanso cholimba, kuti chizitha kupirira mapindikidwe ndi mphamvu popanda kusweka. Komabe, chitsulo cha CRCA sichikhala ndi dzimbiri monga SS 304 ndipo chingafunike zokutira kapena mankhwala owonjezera kuti chitetezeke ku dzimbiri m'malo ena.

Zikafika pamapulogalamu, SS 304 ndi zitsulo za CRCA zili ndi ma niches awo. SS 304 imagwiritsidwa ntchito kwambiri m'makampani opanga zakudya, zida zamankhwala, ndi zomangamanga chifukwa chokana dzimbiri komanso kuyeretsa mosavuta. Amapezekanso m'mafakitale opangira mankhwala, m'malo am'madzi, ndi madera ena kumene dzimbiri ndizovuta. Kumbali inayi, zitsulo za CRCA zimagwiritsidwa ntchito nthawi zambiri pamakampani opanga magalimoto, zomangamanga, komanso kupanga makina chifukwa champhamvu komanso kuuma kwake. Ndiwoyenera makamaka pamapulogalamu omwe amafunikira kulekerera bwino komanso kolimba, monga mapanelo amthupi lamagalimoto ndi zida zamakina olondola.

Kutsiliza

Pomaliza, SS 304 ndi CRCA zitsulo ndi zida ziwiri zosiyana zokhala ndi katundu wapadera komanso ntchito. SS 304 imapambana pakukana kwa dzimbiri ndipo imagwiritsidwa ntchito kwambiri m'malo omwe dzimbiri ndi nkhawa. Ductility wake wabwino, weldability, ndi formability zimapangitsa kukhala zinthu zosunthika oyenera njira zosiyanasiyana zopangira. Kumbali inayi, chitsulo cha CRCA chimadziwika chifukwa cha mphamvu zake zazikulu komanso kuuma kwake, zomwe zimapangitsa kuti zikhale zoyenera pazomangira zomwe zimafunikira kulondola komanso kulimba.

Zikomo powerenga nkhani yathu ndipo tikukhulupirira kuti ikhoza kukuthandizani kuti mumvetsetse bwino kusiyana pakati pa SS 304 ndi CRCA. Ngati mukuyang'ana ogulitsa ndi opanga SS 304 pa intaneti pano, tikukulangizani kuti mupiteko Sino Stainless Steel.

Monga ogulitsa zitsulo zosapanga dzimbiri kuchokera ku Shanghai China, Sino Stainless Steel imapereka makasitomala apamwamba kwambiri. zitsulo zosapanga dzimbiri, zitsulo zosapanga dzimbiri, mapepala okongoletsera zitsulo zosapanga dzimbiri, zitsulo zosapanga dzimbiri machubu, mapaipi achitsulo chosapanga dzimbiri, mbale zitsulo zosapanga dzimbirindipo zitsulo zosapanga dzimbiri pamtengo wopikisana kwambiri.
