Chitoliro Chachitsulo Chosasunthika Kwambiri Kutentha Kwambiri

 

Kutentha kosagwira kuzizira kukopekaChitoliro chachitsulo chosasinthikandi kutentha kwambiri
kukana kwa okosijeni.Ili ndi mphamvu yotentha kwambiri, kukana kwa okosijeni, carburization
kukana, kukana asidi, kukana kwa alkali, kulimba kwamphamvu komanso kukana kuvala.Zopitilira
ntchito kutentha ndi 1150 °C.Kutentha kwanthawi zonse sikuyenera kupitirira madigiri 1050,
ndipo kutentha kwakukulu sikuyenera kupitirira madigiri 1200.Kuchuluka kwa mpweya wa carbon
wa element carbon umene umakhudza ntchito ya mkulu kutentha kugonjetsedwa ndi zosapanga dzimbiri
chubu chachitsulo, ndipamwamba kuuma kwake, koma kumayipitsa pulasitiki ndi kulimba kwake.

Sulfure ndi chonyansa chovulaza muzitsulo.Pamene zitsulo ndi mkulu sulfure zili pansi kukakamizidwa
processing pa kutentha kwambiri, n'zosavuta kukhala Chimaona ndipo nthawi zambiri amatchedwa otentha brittleness.
Phosphorus imatha kuchepetsa kwambiri pulasitiki ndi kulimba kwachitsulo, makamaka pansi
kutentha.Chodabwitsa ichi amatchedwa ozizira brittleness.Mupamwamba zitsulo, sulfure ndi
phosphorous iyenera kuyendetsedwa mosamalitsa.Komabe, kuchokera kumalingaliro ena, kuphatikiza kwa
apamwamba sulfure ndi phosphorous mu otsika mpweya zitsulo akhoza kupanga kudula mosavuta kuthyoka, ndiko
zothandiza kusintha machinability zitsulo.Manganese amatha kuwonjezera mphamvu yachitsulo,
akhoza kufooketsa ndi kuthetsa mavuto a sulfure, ndipo akhoza kusintha hardability wa
zitsulo.

Chitsulo chachikulu cha alloy (chitsulo chapamwamba cha manganese) chokhala ndi manganese ambiri chimakhala ndi kukana kwamphamvu
ndi zina zakuthupi.The antibacterial ndi kutentha kugonjetsedwa ndi chitsulo chosapanga dzimbiri
mankhwala chitoliro amene anatulukira m'zaka zaposachedwapa ndi okondedwa atsopano mu banja zitsulo zosapanga dzimbiri.
Amathandizidwa mwapadera powonjezera zinthu zina za antibacterial monga mkuwa ndi siliva
chitsulo chosapanga dzimbiri.Izi zabwino kwambiri antibacterial kudziyeretsa katundu amasonyeza kuti ntchito yake
chiyembekezo ndi chachikulu kwambiri.

Chubu chachitsulo chosapanga dzimbiri chopanda kutentha chimakhala ndi kukana kwa okosijeni kwapakatikati
gwiritsani ntchito pansi pa madigiri a 1600 ndikugwiritsa ntchito mosalekeza pansi pa madigiri a 1700. Pakati pa 800-1575
madigiri, ndikwabwino kuti musapitirize kugwiritsa ntchito chitsulo chosapanga dzimbiri chopanda kutentha kwambiri
chitoliro, koma pamene mkulu kutentha kugonjetsedwa zosapanga dzimbiri chitoliro mosalekeza ntchito kunja
Kutentha kumeneku, chitsulo chosapanga dzimbiri chimakhala ndi kutentha kwabwino.Kutentha kwakukulu
chitoliro chopanda kuzizira chokoka chitsulo chimakhala ndi mpweya wabwino wa carbide kuposa 316 chitsulo chosapanga dzimbiri,
ndi kutentha pamwamba kungagwiritsidwe ntchito.

Kutentha kwambiri kupirira kuzizira kukopa chubu chachitsulo chokhala ndi makutidwe ndi okosijeni otentha kwambiri
kukaniza.Ili ndi mphamvu yotentha kwambiri, kukana kwa okosijeni, kukana kwa carburization, asidi
kukana, kukana kwa alkali, kulimba kwamphamvu komanso kukana kuvala.Kugwiritsa ntchito mosalekeza
kutentha ndi 1150 ° C.The mwachizolowezi ntchito kutentha si upambana madigiri 1050, ndi
kutentha kwakukulu sikuyenera kupitirira madigiri 1200.
