Nkhani - Zomangamanga-Magulu a H-mitanda: A Core Driver Fueling High-Quality Industry Development

kanasonkhezereka h mtengo mu opanga China

Posachedwapa, ndi kupita patsogolo kosalekeza kwa kukula kwa mizinda ndi kufulumizitsa ntchito zazikulu za zomangamanga, kufunikira kwazitsulo zomangamanga zapamwamba kwawonjezeka. Mwa iwo,H-mtengo, monga gawo lalikulu lonyamula katundu pantchito yomanga, yakhala dalaivala wofunikira pakulimbikitsa chitukuko chapamwamba chamakampani omanga, omwe ali ndi luso lamakina komanso mawonekedwe ogwiritsira ntchito omwe akutsogola msika watsopano.

Mu ntchito yayikulu yokhazikika yokhazikika ku East China, gulu laChithunzi cha HEB150 H-miyalaposachedwapa aikidwa mu zomangamanga zazikulu. Monga mtundu wamba wa H-beam waku Europe, HEB 150 imayamikiridwa ndi magawo omanga pamapangidwe ake okhazikika, kukana kopindika mwamphamvu komanso kukhazikika konyamula katundu. "Poyerekeza ndi zigawo zachitsulo zachikhalidwe, HEB 150 imatha kuchepetsa kuchuluka kwa zolumikizirana ndi 30% pomanga, kufupikitsa kwambiri nthawi yomanga ndikuwonetsetsa chitetezo chamapangidwe," adatero injiniya wamkulu wa polojekitiyi. Ntchitoyi sikuti imangotsimikizira kufunikira kwa zinthu zamtengo wapatali za H-mtengo pomanga nyumba zogona, komanso imapereka chidziwitso pakukweza zitsulo zokhazikika pamsika.

Ngakhale zitsanzo zokhazikika zimagwiritsidwa ntchito kwambiri,mankhwala apamwamba a H-mtengokuyimiridwa ndiZithunzi za ASTM A572-50Hakufulumizitsanso kulowa kwawo muzochita zazikulu. Zimamveka kuti matabwa a ASTM A572-50 H ali ndi kulimba kwa kutentha kochepa komanso kukana kwa dzimbiri, ndipo mphamvu zawo zokolola zimatha kufika kupitirira 345MPa, yomwe ili yoyenera makamaka pamisonkhano yayikulu, milatho ya misewu ndi ntchito zina zomwe zimakhala ndi zofunikira kwambiri. Pakalipano, pomanga mlatho wodutsa mtsinje ku South China, matabwa a ASTM A572-50 H akhala akugwiritsidwa ntchito pazitsulo zazikulu za truss, kuthetsa bwino vuto la kupanikizika pansi pa nyengo zovuta komanso kuonetsetsa moyo wautumiki wa mlathowo.

Kuphatikiza apo,ASTM A572-50 matabwa a flange, monga chopangidwa kuchokera ku H-mtengo, akulitsanso kuchuluka kwa ntchito ya H-mtengo pantchito yomanga. Ndi m'lifupi mwake mwa flange, mtundu uwu wa mtengo umatha kugawa bwino katunduyo ndikuwongolera kukhazikika kwa kapangidwe kake. Zakhala zikugwiritsidwa ntchito kwambiri pomanga nyumba zazikulu zamalonda ndi mafakitale m'zaka zaposachedwa. Munthu amene amayang'anira bizinesi yopanga zitsulo anati: "Mu theka loyamba la chaka chino, kuchuluka kwa ASTM A572-50 matabwa ochuluka a flange kumawonjezeka ndi 40% pachaka, ndipo zinthuzo zatumizidwanso kumisika ya kum'mwera chakum'mawa kwa Asia, kukhala malo atsopano a kukula kwa bizinesi yathu yogulitsa kunja."

Ogwira ntchito m'mafakitale adanenanso kuti kupititsa patsogolo kwachangu kwa H-mtengo womanga sikungowonetsa kukweza kwa makampani omanga zitsulo zamtengo wapatali, komanso kumalimbikitsa luso lamakono la mafakitale azitsulo. M'tsogolomu, ndi kusintha kosalekeza kwa miyezo ya dziko la nyumba zobiriwira ndi zomangamanga zotsika kaboni, mankhwala a H-mtengo omwe ali ndi ntchito zapamwamba, chitetezo cha chilengedwe komanso kusiyanasiyana kwazinthu zambiri zidzathandiza kwambiri pakulimbikitsa chitukuko chapamwamba cha zomangamanga.
