Mpira woponyera, womwe umatchedwanso kuti mpira wogaya, umapangidwa kuchokera ku zitsulo zotayidwa, zitsulo zotayidwa, ndi zinthu zina zotayidwa. Zida zomwe tazitchula pamwambazi ndizosungunula kwambiri ndipo zimayendetsa madzi mosalekeza pambuyo potenthedwa. Panthawi yosungunula, zinthu zambiri zachitsulo monga vanadium, chitsulo ndi manganese zimayamba kuwonjezeredwa ku mpweya wa flue kuti mukwaniritse zokolola zomwe mukufuna komanso zokonzedweratu. Zinthuzi zimatha kutsanulira chitsulo chosungunuka kwambiri mumzere wopangira makina opangira zitsulo.

Mipira yachitsulo ya chrome ndi mipira yopukutira ya chromium yomwe ili ndi gawo lina la chromium, yomwe imagawidwa kukhala mipira yachitsulo ya chromium yapamwamba, mipira yachitsulo ya chromium yapakati ndi mipira yachitsulo yotsika ya chromium. Mipira yachitsulo ya chromium imagawidwa kukhala Mipira Yachitsulo Yapamwamba ya Chromium, Mipira Yachitsulo ya Chromium Yapakatikati ndi Mipira Yotsika ya Chromium Cast Steel. Ndi mbali ya kuuma mkulu, kuvala otsika, ndi otsika breakage, kuponyedwa zitsulo akupera mipira zimagwiritsa ntchito makampani simenti, makampani migodi, mafakitale metallurgical, makampani opanga magetsi ndi makampani zomangamanga.
1, The zipangizo zonse kubala zitsulo nyenyeswa, amene ali mkuwa, molybdenum, faifi tambala ndi zinthu zina zamtengo wapatali zitsulo, amene akhoza bwino kusintha masanjidwewo dongosolo la zitsulo mpira.
2, Zogulitsa zathu zimapangidwa ndi ng'anjo yamagetsi yamagetsi yomwe imatha kutsimikizira kukhazikika kwazinthuzo. Mipira ndiyosavuta kupukuta ndikupunduka mukaigwiritsa ntchito. Ngakhale imatha kukhala yowala komanso yozungulira pakapita nthawi yayitali.
3, The zapamwamba kwambiri lalikulu basi kuzimitsa mafuta mzere kupanga anatengera kutentha mankhwala, amene amaonetsetsa kuuma wabwino ndi yunifolomu wa mankhwala.
1. Njira zitatu zopangira mpira wachitsulo
Pali mitundu itatu ya njira zopangira mpira wachitsulo: kuponyera, kupangira, ndikugudubuza.
(1) Kuponya: Ubwino wa mipira yachitsulo choponyedwa makamaka zimatengera zomwe zili mu chromium. M'zaka zaposachedwa, kukwera mtengo kwa chromium, kuteteza chilengedwe, ndi zinthu zina zapangitsa kuti mtengo wa mipira yachitsulo ikhale yokwera mtengo.
(2) Kupanga: Kugwiritsa ntchito chitsulo chochuluka cha manganese ngati zopangira, nyundo zopangira pneumatic ndi nkhungu za mpira zimagwiritsidwa ntchito kupanga mipira yachitsulo. Mipira yopangira zitsulo imakhala ndi kuphatikiza kokwanira kwa mpweya wambiri, manganese, chromium, ndi zinthu zina za aloyi, ndipo imakhala ndi kuuma kwamphamvu pakupangira kutentha kwapang'onopang'ono, kusiyana pang'ono pakuuma pakati ndi kunja, ndi kusiyana kwa mtengo wake. mipira yopangidwa mwamphamvu kuposa mipira yoponyedwa.
(3) Kugudubuza: Pogwiritsa ntchito zitsulo zachitsulo za manganese monga zopangira, mipira yachitsulo imapangidwa ndi mphero ya skew yokhala ndi zodzigudubuza.
