Chubu cha Chitsulo cha Q420B SHS Square Hollow Section GB/T 6728-2017 Chachikulu Champhamvu Chachikulu 60×60-350×350mm
Q420B SHS Square Hollow Section Steel Chubu
Yopangidwa pansi pa GB/T 6728‑2017, yathuGawo la Q420B lalikulu lokhala ndi dzenje (SHS)Ili m'gulu la machubu achitsulo olimba kwambiri. Imafika pa mphamvu yocheperako ya 420 MPa ndi mphamvu yokoka ya 520 MPa, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pamapulojekiti auinjiniya omwe amafuna kulimbitsa bwino kapangidwe kake komanso mphamvu yonyamula katundu.
Tili ndi ma profiles a sikweya okwana 60×60 mm mpaka 350×350 mm, okhala ndi makulidwe a khoma kuyambira 3.0 mm mpaka 14 mm. Kutalika kwa mphero wamba kumakhala pakati pa 6 m ndi 12 m, ndipo kutalika kodulidwa mwamakonda mpaka 21 m kumaperekedwa kuti kugwirizane ndi zosowa za polojekiti iliyonse.
Q420B SHS iyi imagwira ntchito bwino pa zomangamanga zolimba kwambiri, mafelemu olemera, mafakitale omanga ndi zina zomangira zitsulo zolimba.

Q355B ndi mtundu wa chitsulo champhamvu kwambiri chomwe chimayikidwa nthawi zambiri pa ntchito yomanga chitsulo cholemera.
Imapeza mphamvu yocheperako yotulutsa mphamvu ya 355 MPa ndi mphamvu yokoka ya 470 MPa. Q355B, yomwe imagwira ntchito bwino kuposa zitsulo zokhazikika zomwe zimakhala zochepa, imakwanira bwino ntchito zomwe zimalemedwa ndi zinthu zolemera.
Mphamvu Yochepa Yopezera Zokolola:≥355 MPa
Kulimba kwamakokedwe:≥470 MPa
Kuti mupeze kapangidwe ka mankhwala ndi deta yonse ya kapangidwe ka makina, chonde onani GB/T 6728‑2017 ndi satifiketi yoyesera mphero ya zinthu.
Mulingo wa gawo la Q420B lalikulu lopanda kanthu:
Kukula kwa sikweya:60×60 mm – 350×350 mm
Kukhuthala kwa khoma:3.0‑14 mm
Izi ndi zina mwa kukula komwe timasankha nthawi zonse:
60×60 mm, 80×80 mm, 100×100 mm, 120×120 mm, 150×150 mm,
180×180 mm, 200×200 mm, 250×250 mm, 300×300 mm, 350×350 mm
Kupezeka komaliza kwa kukula kwenikweni ndi makulidwe a khoma kumadalira zofunikira za polojekiti yanu komanso kuthekera kopanga. Chonde onaninso kawiri musanayitanitse.
Kutalika kwa zinthu zomwe zilipo pa Q420B SHS ndi 6 m ndi 12 m.
Kwa mapulojekiti oyenerera, kutalika kodulidwa mwamakonda mpaka 21 m kumapezeka mukapempha.
Timaperekanso ntchito zosiyanasiyana zowonjezera pa kukonza:
Kudula
Kubowola
Kubowola mabowo
kuwotcherera
Kupanga zinthu pogwiritsa ntchito zojambula mwamakonda
Njira zopangira zinthu mwamakondazi zimathandiza kuchepetsa ntchito yopangira zinthu pamalopo ndikuwonjezera mphamvu yoyika zinthu pamalopo.
Lumikizanani nafe
Timapereka njira zingapo zomaliza pamwamba pa Q420B kuti zigwirizane ndi momwe polojekitiyi imagwirira ntchito:
Mapeto a mphero yakuda
Choviikidwa ndi galvanized yotentha
Mapeto opaka utoto wolimba
Chokutidwa ndi primer
Zophimba zopangidwa mwamakonda ngati mupempha
Pa malo ogwiritsidwa ntchito panja kapena m'malo omwe ali ndi zinthu zowononga, zomalizidwa ndi galvanized kapena covered zimapereka chitetezo cha dzimbiri cha zigawo za Q420B SHS.
Kapangidwe ka Uinjiniya Wamphamvu Kwambiri
Zigawo za Q420B zokhala ndi dzenje lalikulu zimagwirizana ndi mapulojekiti omanga omwe amafuna mphamvu yowonjezera komanso magwiridwe antchito odalirika onyamula katundu.
Mafelemu Achitsulo Olemera
Pulasitiki yolimba kwambiri iyi imagwira ntchito bwino pamafelemu akuluakulu ndi ziwalo zonyamula katundu.
Kapangidwe ka Mafakitale
Kugwiritsidwa ntchito kwapadera kumaphatikizapo mitundu yosiyanasiyana ya zomangamanga zamafakitale:
Nyumba zamafakitale
Malo ochitira misonkhano yolemera
Kukhazikitsa kogwirizana ndi uinjiniya
Zipangizo zothandizira
Mapulatifomu ogwirira ntchito m'mapangidwe
Mafelemu akuluakulu achitsulo
Misonkhano yothandizira katundu wolemera
Mizati Yomanga ndi Kulimba
Kutengera ndi zojambula za kapangidwe ka polojekiti, magawo ozungulira awa angagwiritsidwe ntchito pazipilala, zomangira ndi zida zina zomangira.
Mphamvu Yapamwamba Yamakina
Pokhala ndi mphamvu yotsika ya 420 MPa, Q420B imapereka yankho lamphamvu kwambiri pamapulojekiti ovuta kwambiri.
Kapangidwe ka Mbiri Yabwino Kwambiri
Mapangidwe ake ozungulira amapangitsa kuti kapangidwe kake kakhale kogwira ntchito bwino komanso kothandiza kwambiri pantchito zopangira zinthu.
Kusankha Kukula Kwakukulu
Kuphimba kwa kukula kwa 60×60 mm mpaka 350×350 mm kumathandiza kuti zinthu zisinthe mosavuta pa zosowa zosiyanasiyana za uinjiniya.
Zosankha Zosiyanasiyana Zokukuluka kwa Khoma
Kukhuthala kwa khoma kuyambira 3.0 mm mpaka 14 mm kumathandiza kusankha bwino magawo malinga ndi katundu weniweni wa kapangidwe ndi zoletsa za kapangidwe.
Kutha Kupereka Kutalika Kowonjezera
Kutalika kwa katundu wa 6 m ndi 12 m kumabwera monga muyezo. Kutalika kwapadera kwa katundu wofikira 21 m kungakonzedwe, malinga ndi malire opangira ndi mayendedwe.
Zatsimikiziridwa kuti zili ndi zomangamanga zapamwamba
Zigawo za Q420B zokhala ndi dzenje lalikulu zimagwira ntchito bwino kwambiri pa ntchito zaukadaulo zolimba komanso zomangamanga zachitsulo cholemera.
Kuwunika bwino khalidwe kumachitika nthawi yonse yopanga, ndipo kuwunika komaliza kumachitika asanatumize.
Zinthu zowunikira zimakhudza mfundo zazikulu izi:
Kapangidwe ka mankhwala
Mphamvu yobereka
Kulimba kwamakokedwe
Kugwira ntchito kwa kutalika
Kulekerera kwakunja
Kukhuthala kwa khoma
Utali wa chinthu
Kuwongoka
Umphumphu wa weld (wa magawo oswedwa)
Zikalata Zoyesera za Mill Test (MTC) zidzaperekedwa mogwirizana ndi miyezo yogwirizana ya malonda ndi malamulo okhudza maoda.
Pakafunika kasitomala kapena polojekiti, mautumiki owunikira a chipani chachitatu amathanso kukonzedwa.
Chitsulo Cholimba Kwambiri
Zigawo za Q420B zokhala ndi malo opingasa zimapereka mphamvu zambiri pakupanga zinthu zovuta.
Zambiri Zogulitsa
Timapereka magawo ozungulira okhala ndi malo okwana 60 × 60 mm mpaka 350 × 350 mm, okhala ndi makulidwe a khoma kuyambira 3.0 mm mpaka 14 mm.
Ntchito Zopangira Zinthu Mwamakonda
Ntchito yodula, kuboola ndi kupanga zinthu mwamakonda ikhoza kumalizidwa kutengera zojambula zaukadaulo za makasitomala.
Zolemba Zapamwamba Zonse
Timapereka MTC, Satifiketi Yoyambira, mndandanda wa zonyamula katundu, ma invoice amalonda ndi malipoti owunikira malinga ndi zomwe oda iliyonse ikufuna.
Thandizo Lotumiza Kunja Mpaka Kumapeto
Utumiki wathu waukadaulo umakhudza kupanga, kuwunika khalidwe, kulongedza katundu kunja, komanso kukonza zotumizira katundu padziko lonse lapansi.
Pa kutumiza kunja,Q355B SHSnthawi zambiri amamangiriridwa ndi zingwe zachitsulo. Izi zimachepetsa kusuntha panthawi yokweza, kutsitsa ndi kutumiza katundu.
Mapaketi athu otumizira kunja akuphatikizapo njira zotsatirazi:
Chingwe chachitsulo
Zoteteza madzi
Kukulunga koteteza
Kulemba zinthu m'magulu
Zizindikiro zotumizira
Zolemba za kukula ndi kuchuluka
Mayankho oyendera akhoza kukonzedwa kudzera mu chidebe, chonyamulira katundu wambiri kapena njira zina zoyenera zotumizira, kutengera kukula kwa malonda, kuchuluka kwa oda ndi komwe akupita.
