Zovala zokhala ndi mphete ndi zinthu zogudubuza nthawi zambiri zimapangidwa ndi chitsulo chokwera kwambiri cha carbon chromium. CCr15 imagwiritsidwa ntchito pazonyamulira zambiri, mphete zokhala ndi zigawo zazikulu zamtanda ndi zinthu zogubuduza zokhala ndi mainchesi akulu zimagwiritsidwa ntchito zabwino zowumitsa CCrl5SiMn. Chitsulo cha carbon chromium chokhala ndi chitsulo cholimba ndi chitsulo chowumitsidwa chomwe pamwamba ndi mtima zimatha kuuma, ndiye chinthu chabwino kwambiri pakugudubuza zitsulo.

Chifukwa chogwiritsidwa ntchito m'malo osiyanasiyana, mayendedwe ena amafunikira zinthu zapadera zakuthupi, monga kukana kwamphamvu, kukana kutentha kwambiri, kukana kwa dzimbiri ndi zina zotero.

Zitsulo zokhala ndi carburized nthawi zambiri zimagwiritsidwa ntchito ngati mphete ndi zinthu zogubuduza za mayendedwe omwe amakhudzidwa akamagwirira ntchito kapena mayendedwe akuluakulu ndi owonjezera. Carburized kubala zitsulo ndi carburized mkati mwa kuya koyenera osiyanasiyana pamwamba wosanjikiza zinthu monga chromium molybdenum zitsulo, chromium faifi tambala molybdenum chitsulo kapena chromium manganese molybdenum chitsulo, kotero kuti ali ndi minofu wandiweyani ndi kupanga wosanjikiza kuumitsa, pamene gawo lapakati ali. kuuma kochepa komanso kumakhala ndi kulimba kwa mtima wabwino, chifukwa chogwiritsa ntchito bwino zitsulo zokhala ndi carburized, mawerengedwe a moyo wake ndi ofanana ndi chitsulo cha carbon chromium chokhala ndi chitsulo.

Kwa zimbalangondo zomwe zimagwira ntchito kutentha kwambiri, zitsulo zotentha kwambiri zokhala ndi kutentha kwabwino zimagwiritsidwa ntchito pazitsulo. The mayendedwe kukhudzana ndi dzimbiri sing'anga ntchito, amene amapangidwa ndi zosapanga dzimbiri zitsulo.

Ndikoyenera kuzindikira ukhondo wa chitsulo chonyamula, kukwezeka kwaukhondo, kusakanikirana kopanda zitsulo, kuchepa kwa okosijeni, moyo wautali wa kutopa kwa kubereka, ndi vacuum degassing kapena vacuum remelting zitsulo zingathe kukwaniritsa izi. Pazinyalala zomwe zimafuna kudalirika kwakukulu, ziyenera kupangidwa ndi chitsulo chosungunuka cha electroslag.

Titha kupereka mitundu yonse ya zida zonyamula, monga 52100 zitsulo zonyamula, zitsulo zosapanga dzimbiri.
