Kuzizira adagulung'undisa pepalandi mtundu watsopano wa mankhwala amenenso ozizira mbamuikha ndi kukonzedwa ndiotentha adagulung'undisa pepala. Chifukwa chadutsa njira zambiri zoziziritsa kuzizira, mawonekedwe ake apamwamba ndiabwinoko kuposa pepala lopindika lotentha. Pambuyo pa chithandizo cha kutentha, mphamvu zake zamakina zakhalanso bwino kwambiri.
Malinga ndi zofunikira zosiyanasiyana za bizinesi iliyonse yopanga,ozizira adagulung'undisa mbalenthawi zambiri amagawidwa m'magulu angapo. Mapepala oziziritsa ozizira amaperekedwa muzitsulo kapena mapepala athyathyathya, ndipo makulidwe ake nthawi zambiri amawonetsedwa mu millimeters. Pankhani ya m'lifupi, nthawi zambiri amapezeka mu kukula kwa 1000 mm ndi 1250 mm, pamene kutalika kwake kumakhala 2000 mm ndi 2500 mm. Mapepala oziziritsa ozizirawa samangokhala ndi mawonekedwe abwino kwambiri opangira komanso mawonekedwe abwino, komanso amapambana pakukana dzimbiri, kukana kutopa komanso kukongola. Chifukwa chake, amagwiritsidwa ntchito kwambiri pamagalimoto, zomangamanga, zida zapanyumba, zida zamafakitale ndi zina.

Japan JIS muyezo zakuthupi tanthauzo
Kodi SPCCT ndi SPCD zimayimira chiyani?
SPCCT imatanthawuza pepala lozizira lopiringizidwa ndi chitsulo cha carbon ndi Mzere wokhala ndi mphamvu zotsimikizika pansi pa muyeso wa JIS waku Japan, pomwe SPCD imatanthauza pepala lozizira lopiringizika la kaboni ndi mzere wopondaponda pansi pa muyezo wa JIS waku Japan, ndipo mnzake waku China ndi 08AL (13237) wopangidwa ndi mpweya wapamwamba kwambiri. zitsulo.
Kuphatikiza apo, ponena za kutentha kwa pepala lozizira lazitsulo za carbon zitsulo ndi mzere, chikhalidwe cha annealed ndi A, kutentha kwapakati ndi S, 1/8 kuuma ndi 8, 1/4 kuuma ndi 4, 1/2 kuuma ndi 2, ndi kudzaza. kulimba ndi 1. Khodi yomaliza ya pamwamba ndi D yomaliza yosanyezimira, ndi B yomaliza yowala, mwachitsanzo, SPCC-SD imatanthauza pepala lozizira lopiringizika la kaboni kuti ligwiritsidwe ntchito mokhazikika komanso kumaliza kosanyezimira; SPCCT-SB imatanthauza kupsya mtima, kumalizidwa kowala kozizira kozungulira pepala lachitsulo; ndi SPCCT-SB amatanthauza kupsya mtima, kutsirizitsa kowala kozizira kozungulira pepala lachitsulo kuti ligwiritsidwe ntchito ndi kutenthetsa kokhazikika komanso kumalizidwa kosanyezimira. Standard tempering, yowala processing, ozizira adagulung'undisa pepala mpweya chofunika kuonetsetsa makina katundu; SPCC-1D imawonetsedwa ngati pepala lolimba, lopanda gloss, lopiringizidwa ndi chitsulo chozizira.
Makina structural zitsulo kalasi akufotokozedwa motere: S + carbon content + kalata code (C, CK), amene zili carbon ndi mtengo wapakatikati * 100, chilembo C amatanthauza carbon, chilembo K amatanthauza carburized zitsulo.
China GB muyezo zakuthupi tanthauzo
Kwenikweni anawagawa: Q195, Q215, Q235, Q255, Q275, etc. Q limasonyeza kuti zokolola mfundo zitsulo "zokolola" chilembo choyamba cha mawu hanyu pinyin, 195, 215, etc. limasonyeza kuti zokolola mfundo ya mtengo. za kapangidwe ka mankhwala kuchokera ku mfundo, otsika mpweya zitsulo kalasi: Q195, Q215, Q235, Q255, Q275 giredi, kuchuluka kwa kaboni, kukweza kwa manganese, kukhazikika kwake kumakhala kokhazikika.
