304 304L otentha adagulung'undisa mbale zosapanga dzimbiri

Kufotokozera Kwachidule:

Kutentha kotentha tsopano ndi koonda ngati 0.78mm. Pamwamba pa mbale yotentha imakhala ndi zopindika monga sikelo ya iron oxide ndi pitting. Otentha adagulung'undisa pepala ali kuuma otsika, processing zosavuta ndi ductility wabwino. Hot-adagulung'undisa zitsulo mapepala, katundu makina ndi zosakwana processing ozizira, ndipo kachiwiri kulipira processing, koma ndi kulimba bwino ndi ductility.

304L zosapanga dzimbiri

304L zosapanga dzimbiri, amatchedwanso kopitilira muyeso-otsika mpweya zosapanga dzimbiri, ndi zosunthika zosapanga dzimbiri chuma kuti chimagwiritsidwa ntchito popanga zida ndi mbali zomwe zimafuna wabwino wonse katundu (dzimbiri ndi formability).

Chitsanzo Chosiyana za 304 ndi 304L Hot adagulung'undisa ndi Cold adagulung'undisa kufotokozera

1.Pamwamba pa pepala lokutidwa ndi kuzizira pamakhala mulingo winawake wonyezimira. Ndi yosalala mpaka kukhudza ndipo ikufanana ndi chikho chofala kwambiri chachitsulo chomwe chimamwa madzi.

2.Ngati chinsalu chosakuluka sichisosedwa, chimakhala chofanana ndi mawonekedwe azitsulo zambiri pamsika. Pamwamba pake pali dzimbiri lofiira, ndipo pamwamba pake palibe dzimbiri ndi lofiirira-wakuda (iron oxide scale).

3.Ubwino wa magwiridwe antchito ndi ozizira ndi:

(1) Kulinganiza bwino ndikokwera, ndipo kusiyana kwamakulidwe azitsulo zokulirapo sikuzizira 0.01 ~ 0.03mm.

(2)Kukula kwake ndi kocheperako, kozizira kozizira kozizira kumatha kukulungidwa ndi chingwe chachitsulo cha 0.001 mm; kuthamanga kotentha tsopano ndi koonda ngati 0.78 mm.

(3)Ubwino wam'mwamba ndi wapamwamba, ndipo mbale yachitsulo yozizira imatha kupanga kalilole pamwamba; pomwe pamwamba pa mbale yolumikizidwa yotentha ili ndi zolakwika monga sikelo ya iron oxide ndi pitting.

(4) Mapepala ozizira amatha kusintha malinga ndi zomwe ogwiritsa ntchito amagwiritsa ntchito monga kulimba kwamphamvu ndikukonzekera zinthu monga kupondaponda katundu.

Cold anagubuduza ndi otentha anagubuduza ndi umisiri awiri osiyana anagubuduza. Monga momwe dzinali likusonyezera, kuzizira kozizira kumachitika ngati chitsulo chitenthe. Kuuma kwa chitsulo ichi ndi kwakukulu. Hot anagubuduza ndi chitsulo amapangidwa ndi kutentha, Mwatsatanetsatane:

Otentha adagulung'undisa pepala ali kuuma otsika, processing zosavuta ndi ductility wabwino.

Pepala lokulungira lozizira limakhala lolimba kwambiri ndipo limakhala lovuta kulikonza, koma silipunduka mosavuta ndipo lili ndi mphamvu zambiri.

Pepala lokutidwa lotentha limakhala ndi mphamvu zochepa, mawonekedwe apamwamba amakhala osawuka (okhala ndi makutidwe ndi okosijeni otsika komanso osalala), koma pulasitiki ndiyabwino, mbale yayitali komanso yolimba. Cold pepala lokulunga: mphamvu yayikulu, kuuma kwakukulu, kumaliza kwakukulu, pepala lochepa kwambiri, lingagwiritsidwe ntchito kupondaponda.

Hot-adagulung'undisa zitsulo mapepala, katundu makina ndi zosakwana processing ozizira, ndipo kachiwiri kulipira processing, koma ndi kulimba bwino ndi ductility.

Cold-adagulung'undisa chitsulo pepala ali ndi mulingo wina wa ntchito kuumitsa, otsika kulimba, koma akhoza kukwaniritsa zokolola chiŵerengero, ntchito zidutswa ozizira kupinda masika ndi mbali zina, ndipo chifukwa mfundo zokolola ali pafupi ndi kwamakokedwe mphamvu, palibe ngozi pamagwiritsidwe. Kulosera zamtsogolo, ngozi imatha kuchitika katundu akatapula katundu wololezedwa.
