KODI STINLESS zitsulo NDI CHIYANI?

KODI STINLESS zitsulo NDI CHIYANI?

Chitsulo chosapanga dzimbiri ndi aloyi yachitsulo ndi chromium. Ngakhale zosapanga dzimbiri ziyenera kukhala ndi 10.5% chromium, zigawo zenizeni ndi ma ratios zimasiyana malinga ndi kalasi yomwe yapemphedwa komanso momwe chitsulo chimafunidwira.

MMENE ZINTHU ZOSAPANGA AMAPANGIDWA

Njira yeniyeni ya kalasi yazitsulo zosapanga dzimbiri idzasiyana m'magawo apambuyo pake. Momwe chitsulo chachitsulo chimapangidwira, kugwira ntchito ndi kumalizidwa kumathandizira kwambiri kudziwa momwe chikuwonekera ndikuchita.

Musanayambe kupanga chitsulo chotulutsidwa, choyamba muyenera kupanga alloy yosungunuka.

Chifukwa cha izi, magulu ambiri azitsulo amagawana njira zoyambira.

Gawo 1: Kusungunuka

Kupanga zitsulo zosapanga dzimbiri kumayamba ndi kusungunula zitsulo ndi zowonjezera mu ng'anjo yamagetsi yamagetsi (EAF). Pogwiritsa ntchito maelekitirodi amphamvu kwambiri, EAF imatenthetsa zitsulo m'kupita kwa maola ambiri kuti apange chosakaniza chosungunuka, chamadzimadzi.

Popeza chitsulo chosapanga dzimbiri chimatha kubwezeredwanso 100%, maoda ambiri osapanga dzimbiri amakhala ndi zitsulo zofika 60%. Izi zimathandiza osati kuwongolera ndalama zokha komanso kuchepetsa kukhudzidwa kwa chilengedwe.

Kutentha kwenikweni kumasiyana malinga ndi mtundu wazitsulo zopangidwa.

Khwerero 2: Kuchotsa Zokhala ndi Mpweya

Mpweya umathandizira kukulitsa kuuma ndi mphamvu yachitsulo. Komabe, carbon yochuluka ingayambitse mavuto monga mvula ya carbide panthawi yowotcherera.

Musanaponye chitsulo chosapanga dzimbiri chosungunula, kulinganiza ndi kuchepetsa mpweya wa carbon pamlingo woyenera ndikofunikira.

Pali njira ziwiri zothanirana ndi carbon.

Yoyamba ndi kudzera mu Argon Oxygen Decarburization (AOD). Kulowetsa mpweya wa argon muzitsulo zosungunula kumachepetsa mpweya wa carbon ndi kutaya pang'ono kwa zinthu zina zofunika.

Njira ina yomwe imagwiritsidwa ntchito ndi Vacuum Oxygen Decarburization (VOD). Mwanjira imeneyi, zitsulo zosungunuka zimasamutsidwa kupita kuchipinda china kumene mpweya umalowetsedwa muzitsulo pamene kutentha kumagwiritsidwa ntchito. Vutoli limachotsa mpweya wotuluka m'chipindamo, ndikuchepetsanso mpweya wa carbon.

Njira zonsezi zimapereka kuwongolera kolondola kwa zinthu za kaboni kuti zitsimikizire kusakaniza koyenera komanso mawonekedwe enieni muzomaliza zazitsulo zosapanga dzimbiri.

Gawo 3: Kukonza

Pambuyo kuchepetsa mpweya, komaliza kugwirizanitsa ndi homogenization kutentha ndi umagwirira kumachitika. Izi zimatsimikizira kuti chitsulocho chikukwaniritsa zofunikira za kalasi yomwe akufuna komanso kuti chitsulocho chikhale chogwirizana mu batch yonse.

Zitsanzo zimayesedwa ndikuwunikidwa. Zosintha zimapangidwira mpaka osakaniza akwaniritse zofunikira.

Khwerero 4: Kupanga kapena Kuponya

Ndi chitsulo chosungunula chopangidwa, mazikowo ayenera kupanga mawonekedwe akale omwe amagwiritsidwa ntchito kuziziritsa ndi kugwirira ntchito chitsulo. Maonekedwe enieni ndi miyeso yake idzadalira mankhwala omaliza.
