Dinani batani la kumanja
1. Kusankha Zinthu Zopangira
Chitsulo chachitsulo chapamwamba kwambiri kapena chitsulo chodulidwa chimasankhidwa kuti zitsimikizire kuti kapangidwe ka mankhwala kakukwaniritsa zofunikira za ASTM A709.
2. Kupanga Zitsulo
Njira zoyambira za Oxygen Furnace (BOF) kapena Electric Arc Furnace (EAF) zimagwiritsidwa ntchito kusungunula zipangizo zopangira.
Zinthu zosakaniza monga manganese, silicon, mkuwa, nickel, ndi chromium zimawonjezedwa kuti zikwaniritse mtundu ndi mawonekedwe omwe mukufuna.
3. Kuponya
Chitsulo chosungunuka chimaponyedwa mu slabs pogwiritsa ntchito njira zoponyera mosalekeza kapena njira zoponyera ingot.
4. Kugubuduza Kotentha
Ma slabs amatenthedwa kutentha kwambiri (~1200°C) ndipo amakulungidwa m'mapepala a makulidwe ndi m'lifupi mofunikira.
Kuzungulira ndi kuziziritsa kolamulidwa kumawonjezera mphamvu zamakanika monga mphamvu yotulutsa ndi kulimba.
5. Kuchiza ndi Kutentha (ngati pakufunika)
Magiredi ena (monga HPS) amatha kuchepetsedwa mphamvu kuti awonjezere mphamvu, kulimba, komanso kusinthasintha.
6. Chithandizo cha pamwamba
Ma mbale amachotsedwa pakhungu (kusakaniza, kuphulitsa ndi mfuti) kuti achotse zigawo za oxide ndikukonzekera kukonzedwanso kapena kuphimba.
7. Kudula ndi Kumaliza
Ma mbale amadulidwa malinga ndi kukula kwake, amawunikidwa, ndikuyesedwa kuti awone ngati ali ndi mawonekedwe a makina, kapangidwe ka mankhwala, komanso kulondola kwa miyeso yake malinga ndi miyezo ya ASTM A709.
8. Kuwongolera ndi Kuyang'anira Ubwino
Mbale iliyonse imayesedwa mwamphamvu:
Mayeso a mphamvu yokoka ndi kukwera
Mayeso a Charpy a zotsatira
Kuyesa kwa Ultrasonic kapena ultrasound kwa zolakwika zamkati
Kuyang'ana kwa miyeso ndi pamwamba
9. Kupaka ndi Kutumiza
Mapepala omalizidwa amaikidwa m'magulu, amalembedwa zilembo, ndipo amakonzedwa kuti atumizidwe kwa makasitomala kapena malo omanga.
Mapepala achitsulo a STM A709 makamaka ndi mapepala achitsulo olimba kwambiri, osapanga ma alloy ambiri omwe amapangidwa kuti azigwiritsidwa ntchito pa milatho ndi ntchito zina zolemera za kapangidwe kake. Kuphatikiza kwawo mphamvu, kulimba, ndi kusinthasintha kumapangitsa kuti akhale abwino kwambiri pamapulojekiti ofunikira kwambiri.

1. Kulongedza Mapaketi Okhala ndi Mitolo Yochuluka
Mapepala achitsulo amasankhidwa bwino malinga ndi kukula ndi zofunikira zosiyanasiyana. Ma spacer amatabwa kapena achitsulo amaikidwa pakati pa gawo lililonse kuti mbalezo zikhale zosalala, kupewa kukhudzana mwachindunji komanso kupewa kuwonongeka kwa pamwamba. Mapaketi onse omangidwa amamangiriridwa mwamphamvu ndi zingwe zachitsulo kuti zitsimikizire kukhazikika konse panthawi yoyenda ndikupewa kusuntha kapena kumasuka.
2. Kupaka Mabokosi ndi Ma Pallet
Mapepala ang'onoang'ono komanso apamwamba achitsulo amagwiritsa ntchito njira zomangira ma crate kapena ma pallet amatabwa. Mapepala ndi filimu yapulasitiki yosagwira dzimbiri zimayikidwa mkati mwa mapaketi kuti zisanyowe ndi dzimbiri. Njira yokhazikika iyi yomangira katundu kunja imapangitsa kuti katundu anyamulidwe, kutsitsa katundu ndi kusungidwa m'nyumba zosungiramo katundu zikhale zosavuta, komanso imasintha bwino mayendedwe apadziko lonse lapansi komanso malo osungiramo katundu kwa nthawi yayitali kunja kwa dzikolo.
3. Kutumiza Zinthu Zambiri
Mapepala achitsulo akuluakulu komanso akuluakulu amaperekedwa mochuluka kudzera panyanja kapena pamtunda. Mabuloko amatabwa ndi zinthu zodzitetezera zaukadaulo zimagwiritsidwa ntchito pamalo olumikizirana ndi mapepalawo. Izi zimateteza bwino kutuluka ndi kugundana panthawi yoyendera, kuteteza pamwamba pa mbale yachitsulo ndi kulimba kwa kapangidwe kake konse.
Mgwirizano wokhazikika ndi makampani otumiza katundu monga MSK, MSC, COSCO ndi unyolo wautumiki wothandiza pa logistics, komanso unyolo wautumiki wothandiza pa logistics ndi zomwe tikukukhutiritsani.
Timatsatira miyezo ya ISO9001 yoyendetsera bwino njira zonse, ndipo tili ndi ulamuliro wokhwima kuyambira kugula zinthu zolongedza mpaka kukonza nthawi yonyamula magalimoto.
1. Kodi n'chiyaniMbale yachitsulo ya ASTM A709?
ASTM A709 ndi mbale yachitsulo yolimba kwambiri yomwe imagwiritsidwa ntchito kwambiri pomanga milatho ndi zomangamanga zolemera. Imapereka mphamvu zabwino, kulimba, komanso kupirira nyengo, zomwe zimapangitsa kuti ikhale yoyenera panja komanso pamalo ovuta.
2. Kodi ASTMMbale yachitsulo ya A709kukhala wolukidwa?
Inde. Ikhoza kulumikizidwa pogwiritsa ntchito njira zachikhalidwe. Pa mbale zokhuthala kapena zolumikizira pa kutentha kochepa, kutentha koyambirira ndi kutentha pambuyo pa kulumikiza kungafunike. Ma mbale okhwima amafunika njira zowongolera zolimba kwambiri zolumikizira.
3. Kodi pali makulidwe ndi kukula kotani komwe kulipo?
Kukhuthala: 6–250 mm; M'lifupi: Pamwamba 4000 mm; Kutalika: Pamwamba 12000 mm, kapena kukula kwina kulikonse kungadulidwe motsatira dongosolo.
4. Kodi kusiyana pakati pa ASTM A709 ndi ASTM A36 ndi kotani?
Chifukwa cha mphamvu zake zapamwamba komanso kulimba kwake, ASTM A709 imaonedwa kuti ndi chisankho choyenera kwambiri pa milatho ndi nyumba zolemera. ASTM A36 ndi yoyenera kugwiritsidwa ntchito popanga zinthu komanso pazinthu zina zonse.
5. Kodi kuyezetsa kumachitika bwanji?
Kuyesa mphamvu yokoka, kuyesa kukhudza (kutentha pang'ono), kusanthula kapangidwe ka mankhwala, kuyang'ana mawonekedwe ndi mawonekedwe a pamwamba.
6. N’chifukwa chiyani muyenera kusankha ASTM A709?
"Chifukwa idapangidwira ntchito zapamwamba kwambiri m'milatho ndi zomangamanga zovuta. ASTM A709 imapereka mphamvu zapamwamba kwambiri, kusinthasintha bwino, komanso khalidwe labwino, ndipo magwiridwe ake abwino kwambiri amawapangitsa kukhala oyenera milatho yonse, milatho yapamwamba, ndi nyumba zolemera," adatero Bagwell. Kuphatikiza kwake mphamvu zambiri, kulimba, komanso magwiridwe antchito otsimikizika kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mlatho ndi nyumba zokhazikika nthawi yayitali, makamaka m'malo ovuta.
