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. 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.

4. Kodi kusiyana pakati pa ASTM A709 ndi ASTM A36 ndi kotani?
ASTM A709 ili ndi mphamvu zambiri, kulimba bwino, komanso mphamvu zina zosinthira nyengo.
ASTM A36 ndi chitsulo chokhazikika cha kaboni, makamaka chogwiritsidwa ntchito popanga zinthu zambiri, chomwe sichimakonzedwa bwino kuti chigwiritsidwe ntchito pa milatho kapena malo ovuta.
5. Kodi mbale yachitsulo ya ASTM A709 imayesedwa bwanji?
Mayeso olimba kuti atsimikizire kukolola ndi mphamvu zake zonse
Mayeso a Charpy a kulimba kwa kutentha kochepa
Kusanthula kwa mankhwala kuti kutsimikizire kapangidwe ka alloy
Kusalala ndi mawonekedwe a mawonekedwe
6. N’chifukwa chiyani mungasankhe mbale yachitsulo ya ASTM A709?
Mphamvu yapamwamba kwambiri yochepetsera thupi
Kutha kupotoza bwino komanso magwiridwe antchito opangira zinthu
Magiredi osankha a nyengo kuti mukhale olimba kwa nthawi yayitali
Yoyenera malo otentha pang'ono komanso opsinjika kwambiri
