Chinsinsi chopangaKupanga Zozizirapatsogolokuletsandikusankha kuchuluka koyenera kuti mupewe zofooka zotchulidwa pamwambapa. Nthawi zambiri, lingaliro lotseguka lozizira limatsimikiziridwa molingana ndi kapangidwe ka mankhwala, mawonekedwe opangira micrestruction State State ndi kukula kwa zinthu zoyipa, potengera deta yoyenera.
Mwambiri, chosavuta kupangidwa ndi mapangidwe a chopanda kanthu, kuthamanga mwachangu pambuyokuletsa, ndipo pang'onopang'ono njira ina mozungulira. Kwa chitsulo cha carbon ndi zitsulo zotsikaKungoyiwala, kuzizira kwa mpweya kumatha kutengera pambuyokuletsa. Ndi zovuta za AlloyKungoyiwalaKapenanso kuwunika kwakukulu, mutaipitsa kuyenera kutengedwa dzenje kapena kuzirala kwa ng'ani.
Ngati chitsimikiziro cha carbon steel, chitsimikiziro cha alloy chitsulo ndikukhala ndi chitsulo chodzaza ndi mpweyakuletsa, Carbider carbide imayendetsa pamalire a tirigu, omwe angakhudze kwambiri ntchito yodziipitsa. Chifukwa chake, mtundu uwu watulutsidwa mpaka 700 ℃ ndi mpweya wozizira, wophulika kapena utsi mwachangu mutatha kukhululukidwa, kenakoKungoyiwalaamaikidwa m'maenje kapena ng'anjo kuti aziziziritsa pang'onopang'ono.

Kwa chitsulo chachitsulo, zitsulo za ferterit ndi zitsulo zina popanda kuphatikiza gawo, kuzizira kwambiri kumatha kutengedwa chifukwa kulibe gawo la magawo gawo pozizira pambuyokuletsa. Kuphatikiza apo, kuzizira mwachangu kumafunikiranso kupeza mawonekedwe amodzi ndipo amateteza kukhazikika pang'onopang'ono kwa chitsulo chachangu pa 475 ℃. Chifukwa chake, mtundu uwu ukhoza kukhala wopanda mpweya pambuyokuletsa.
Zitsulo zokhalamo mpweya, monga chitsulo cha abortic, chitsulo chosapanga chitsulo, chothamanga kwambiri cha zitsulo zozizira, ndi zina zambiri zokhala ndi micressruction komanso zosavuta kutulutsa michere yozizira . Chifukwa chake, mtundu uwu kuyenera kuyenera kukhazikika pang'onopang'ono pambuyo pakekuletsa.
Kwa malo otsetsereka oyera, monga chinsinsi cha chrome-nickel, kuti tipewe malo oyera pakuzizira, kuzizira kumayenera kuchitika molingana ndi zowonjezera zina zozizira.
Kungoyiwalawopangidwa ndi chitsulo ali ndi mtengo wozizira msanga pambuyokuletsa, pomwe opangidwa ndi zitsulo ing ali ndi mtengo wozizira kwambiri. Kuphatikiza apo, kufooka ndi kukula kwakukulu kwa gawo kuyenera kukhazikika pang'onopang'ono mutatha kufooka chifukwa chozizira kutentha, pomwe kuwunika ndi kukula kocheperako kumatha kukhazikika mwachangu mukamaletsedwa.
