Chitsulo champhamvu kwambiriangagwiritsidwe ntchito muzitsulo zazitsulo kuti apulumutse kuchuluka kwa zitsulo zomwe zimagwiritsidwa ntchito komanso kuchepetsa mtengo wazitsulo zopangira zitsulo, zoyendetsa ndi kuyika.Popeza zida zamakina azitsulo zamphamvu kwambiri zimakhala ndi kusiyana kosagwirizana ndi chitsulo wamba, akatswiri a kunyumba ndi kunja achita kafukufuku wambiri pakugwiritsa ntchito zitsulo zamphamvu kwambiri m'zaka zaposachedwa.

Kuphatikiza pakupanga kwamembala wololera, zida zachitsulo zolimba kwambiri zimafunikira kulumikizana koyenera pakati pa mamembala achitsulo champhamvu kwambiri kuti apange dongosolo lotetezeka komanso lodalirika.

Kupita patsogolo kwa kafukufuku wa njira ziwiri zofunika zolumikizira zitsulo zolimba kwambiri (kuwotcherera ndi kutsekereza) kunyumba ndi kunja kumayambitsidwa, kuphatikiza: kafukufuku wokhudzana ndi kunyamula kwamphamvu kwamphamvu kwamphamvu kwazitsulo zamatako, kafukufuku wonyamula katundu. Kugwiritsiridwa ntchito kwa kulumikiza kwachitsulo champhamvu kwambiri chachitsulo chachitsulo, kafukufuku wonyamula katundu wazitsulo zolimba kwambiri zamtundu wachitsulo, kafukufuku wokhudzana ndi kunyamula katundu wazitsulo zamphamvu kwambiri zamtundu wa chitsulo ndi kafukufuku wa hydrogen- kuchedwetsa kusweka kwa mabawuti amphamvu kwambiri a sitandade 12.9, ndi zina zotero, ndikuwonetsa kupita patsogolo kwa kafukufuku wa Yunivesite ya Tongji.Yunivesite ya Tongji, ikufotokoza mwachidule momwe kafukufukuyu akuyendera komanso kuyang'ana patsogolo pa kafukufuku wamtsogolo.

Kugwiritsiridwa ntchito kwa mphamvu zofananira pansi pazitsulo zowotcherera zitsulo zamphamvu kwambiri kungachepetse kutentha kwa kutentha kwa preheating, kuchepetsa kuwonongeka kwa kuwotcherera ndikuwongolera ductility ya olowa.

Komabe, kufananitsa kocheperako kumatha kukhudza kwambiri mphamvu yonyamula katundu wa olowa.Ofufuza ambiri asonyeza kuti zotsatira za European code EC3 pa pansi-mphamvu mafananidwe wa welded olowa mphamvu mawerengedwe mawerengedwe ali kwenikweni wololera kapena ndiwofatsa.

Mkulu-mphamvu zitsulo kufewetsa chodabwitsa pambuyo kuwotcherera ndi kukula kwa mlingo wa kufewetsa ndi zitsulo kulimbikitsa limagwirira, kugudubuzika ndondomeko ndi tilinazo kutentha mankhwala, chifukwa mkulu-mphamvu zitsulo mu akugubuduza ndondomeko wakhala chimodzi kapena zingapo kutentha mankhwala, zitsulo pafupi. The weld ndi kutentha athandizira ndi kuzirala kutentha mkombero processing, kotero kuti sangathe kukhala choyambirira makina katundu, choncho kutentha bwanji zone.

Zinthu zenizeni zomwe zimakhudza mphamvu ya olowa wowotcherera ndi kulimba kwa zida zowotcherera, m'lifupi mwazowotcherera, mphamvu zofewa zone, kufewetsa zone m'lifupi, kuchuluka kwa makulidwe a gawo lowotcherera ndi ngodya ya weld.

1) njira zosiyanasiyana zotengera katundu wonyezimira zimakhudza kwambiri anti-slip coefficient, ndipo mtengo wa anti-slip coefficient of the Chinese code ndi 7% mpaka 20% kuposa mtengo wa European code.

2) Pamalo owombera kuwombera, mtengo woyezera wa anti-slip coefficient wa chitsulo champhamvu kwambiri uli pakati pa 0.45 ndi 0.50 molingana ndi malamulo aku Europe, ndipo ngati chitsimikiziro chachitetezo chikuganiziridwa, mtengo wofananira umakhala pakati. 0.4 ndi 0.45.

3) TWotsutsa-kutsetsereka koyenera wa red dzimbiri pamwamba pambuyo kuwomberedwa kuphulika kwa chitsulo champhamvu kwambiri amakhala wamkulu kuposa kuwombera pamwamba.

4) Tiye anti-slip coefficient ofapamwamba tensileswaya wamtaliburashi pamwamba malinga ndi miyambo ya ku Ulaya ili pafupi ndi mtengo womwe umatengedwa malinga ndi chikhalidwe cha ku China, anti-slip coefficient imachepa ndi kuwonjezeka kwa kalasi yachitsulo.

5) Chithandizo chapamwamba cha chitsulo champhamvu champhamvu chowomberedwa ndikukutidwa ndi utoto wokhala ndi zinc wolemera amatha kuwonjezera kukhazikika kwa anti-slip coefficient of the friction surface, ndipo muyezo wa anti-slip coefficient nthawi zambiri umakhala wocheperako kuposa malo ena. njira zothandizira.Makulidwe a utoto wopaka utoto wopangidwa ndi zinc wolemera kwambiri amathandizira kuwongolera kokwanira kwa slip resistance coefficient, ndipo kutsetsereka kwa coefficient of coefficient of the thick coefficient ndi pafupifupi 10% apamwamba kuposa zokutira zopyapyala.
