Pamwamba pa Rockwell kuuma kwa annealed plain carbon steel nthawi zambiri kumakhala 55+-3, ndipo kulimba kwa chitsulo chosasunthika chopanda chitsulo chosasunthika ndi pamwamba pa 80. 100-2000 mm; onse amapangidwa ndi chingwe chopiringizika chotentha kapena mbale yachitsulo. .
CRS ndi chidule cha English ozizira adagulung'undisa zitsulo, ndiye ozizira adagulung'undisa zitsulo. Amatanthauza kugudubuza kwachitsulo. Mwachitsanzo, q235 wamba mpweya zitsulo mbale akhoza ozizira adagulung'undisa, ndi 10 # zitsulo mbale akhoza ozizira adagulung'undisa. Kuuma kwake kumatha kukhala pamlingo wofananira malinga ndi kalasi yachitsulo yomwe imagwiritsidwa ntchito. .
Kodi pepala lozizira kwambiri lolimba kuposa spcc ndi lotani? .
Cold-anagulung'undisa pepala ndi chidule cha wamba mpweya structural zitsulo ozizira adagulung'undisa pepala, wotchedwanso ozizira adagulung'undisa pepala, amadziwika kuti ozizira adagulung'undisa pepala, ndipo nthawi zina molakwika olembedwa ngati pepala ozizira adagulung'undisa. Chipinda chozizira chimapangidwa ndi chingwe chachitsulo cha carbon structural chitsulo choyaka moto, chomwe chimazizira kwambiri kuti chizikulungidwa kukhala zitsulo zosakwana 4mm. .
Tsamba lozizira lozizira limagawidwa kukhala: 1/8 molimba, 1/4 molimba, 1/2 yolimba komanso yolimba. Nthawi zambiri pali magawo awiri akulu a kuuma mtengo: HRB (Rockwell) HV (Vickers) motere: Chizindikiro chosiyanitsa chamtundu HRB (Rockwell) HV (Vickers) 1/8 cholimba. .
Pickling mbale ndi mbale yotentha yomwe imayendetsedwa ndi njira monga dephosphorization (kuchotsa dzimbiri, zotsalira, ndi zina zotero, zopangidwa panthawi yotentha) ndi njira zina zokometsera pamwamba kuti zipeze mbale yachitsulo yogwira ntchito bwino kuposa yotentha. - adagulung'undisa pamwamba. Zitha kuwoneka kuchokera mukupanga kwake kuti kuuma kwake kumatenthedwa ndi kalasi yomweyi. .
Palibe kusiyana kwenikweni pakuuma kwa pamwamba pakati pa kuzizira kozizira ndi malata. Chifukwa pamwamba pa malata amangokutidwa ndi wosanjikiza wa zinki kuchokera ku ma microns ochepa kufika pafupifupi ma microns 20 pa gawo lapansi. Magawo ang'onoang'ono amakhala ozizira komanso ogudubuzika. The kuuma makamaka zimadalira kalasi ya zinthu, ndi sukulu amasiyana. .
Tengani DC01, DC03 mwachitsanzo. DC01 malire apamwamba a mphamvu zokolola 280 DC03 malire apamwamba a zokolola mphamvu 240 , dc06+ze, zimagwirizana ndi pepala lozizira, chiwerengerocho chikuyimira kalasi yosindikizira, ndipo chiwerengero chachikulu ndi.
Mapepala oziziritsa ozizira amapangidwa ndi koyilo yotentha yotentha ngati zopangira, zopindidwa kutentha kwa firiji pansi pa kutentha kwa recrystallization, ndipo kuuma kwake kuli pafupifupi 150HV. Makina ometa ubweya nthawi zambiri amapangidwa ndi chitsulo chachitsulo, cholimba cha HRC55 ~ 58 °, chomwe chimatha kudula ambiri aiwo.
