Dinani batani la kumanja
1. Kukonzekera Zinthu Zopangira
Kusankha chitsulo cha nkhumba, chitsulo chotsalira, ndi zinthu zosakaniza.
3. Kuponya Kosalekeza
Kuyika mu slabs kapena maluwa kuti mupitirire kugwedezeka.
5. Kutentha (Ngati mukufuna)
Kubwezeretsa kapena kubwezeretsanso kuti zikhale zolimba komanso zofanana.
7. Kudula ndi Kuyika
Kudula kapena kudula molingana ndi kukula kwake, mankhwala oletsa dzimbiri, ndi kukonzekera kubereka.
2. Kusungunula ndi Kuyeretsa
Furnace ya Electric Arc (EAF) kapena Furnace ya Basic Oxygen (BOF)
Kuchotsa sulfurization, kuchotsa oxidation, ndi kusintha kwa kapangidwe ka mankhwala.
4. Kugubuduza Kotentha
Kutentha → Kuzungulira Koyipa → Kumaliza Kuzungulira → Kuziziritsa
6. Kuyendera ndi Kuyesa
Kapangidwe ka mankhwala, mawonekedwe a makina, ndi ubwino wa pamwamba.
Mbale yachitsulo cha carbon ya ASTM A283 ndi chitsulo chogwiritsidwa ntchito m'njira zosiyanasiyana chomwe chimagwiritsidwa ntchito kwambiri pa ntchito zomanga ndi mafakitale chifukwa cha kusinthasintha kwake, kapangidwe kake, komanso kugwiritsa ntchito bwino ndalama. Ntchito zodziwika bwino zimaphatikizapo:
Kapangidwe ka Nyumba:
Matabwa, zipilala, zothandizira, nyumba zosungiramo katundu, ndi nyumba za fakitale
Milatho ndi Uinjiniya Wanyumba:Milatho yopepuka mpaka yapakatikati, zotchingira, ndi nyumba zothandizira
Zipangizo Zomangira ndi Zoyendera:Mabotolo a sitima, matupi a magalimoto, ndi zotengera zotumizira
Ziwiya Zokakamiza & Zipangizo Zamakampani:Ziwiya zotsika mphamvu, matanki osungiramo zinthu, ndi zida zonse za mafakitale
Ntchito Zina:Kupanga makina ambiri ndi zida zopepuka
Chidule:
Mbale yachitsulo ya ASTM A283 ndi yabwino kwambiri pakugwiritsa ntchito kapangidwe kopepuka mpaka kapakatikati, zomwe zimapangitsa kuti ikhale yosavuta kupanga, kusinthasintha, komanso kugwiritsa ntchito bwino ndalama.
1) Ofesi ya Nthambi - chithandizo cha Chisipanishi, chithandizo cha msonkho, ndi zina zotero.
2) Matani opitilira 5,000 a katundu alipo, okhala ndi makulidwe osiyanasiyana
3) Kuyang'aniridwa ndi mabungwe odalirika monga CCIC, SGS, BV, ndi TUV, ndi ma CD oyenera kuyenda panyanja
| Ayi. | Chinthu Choyendera | Kufotokozera / Zofunikira | Zida Zogwiritsidwa Ntchito |
| 1 | Kuwunikanso Zikalata | Tsimikizirani MTC, mtundu wa zinthu, miyezo (ASTM/EN/GB), nambala ya kutentha, gulu, kukula, kuchuluka, mankhwala ndi makhalidwe a makina. | MTC, zikalata zoyitanitsa |

1. Mitolo Yodzaza
-
Mapepala achitsulo amaikidwa bwino malinga ndi kukula kwake.
-
Zolumikizira zamatabwa kapena zachitsulo zimayikidwa pakati pa zigawo.
-
Mapaketi amamangiriridwa ndi zingwe zachitsulo.
2. Kupaka Katoni kapena Pallet
-
Ma mbale ang'onoang'ono kapena apamwamba amatha kupakidwa m'mabokosi amatabwa kapena pa ma pallet.
-
Zipangizo zosanyowa monga pepala loletsa dzimbiri kapena filimu ya pulasitiki zitha kuwonjezeredwa mkati.
-
Yoyenera kutumiza kunja ndipo ndi yosavuta kuigwiritsa ntchito.
3. Kutumiza Mochuluka
-
Mapepala akuluakulu akhoza kunyamulidwa ndi sitima kapena galimoto yonyamula katundu wambiri.
-
Matabwa ndi zinthu zotetezera zimagwiritsidwa ntchito kuti zisagundane.
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 machitidwe onse, ndipo tili ndi ulamuliro wokhwima kuyambira kugula zinthu zolongedza mpaka kukonza nthawi yoyendera magalimoto. Izi zimatsimikizira kuti ma H-beams akuchokera ku fakitale mpaka kumalo a polojekiti, kukuthandizani kumanga pamaziko olimba a polojekiti yopanda mavuto!
1. Kodi mbale yachitsulo ya ASTM A283 ndi chiyani?
ASTM A283 ndi mbale yachitsulo yopangidwa ndi mpweya wochepa, yokhala ndi mpweya wochepa, yotha kusungunuka bwino, yolimba, komanso yogwira ntchito bwino. Imagwiritsidwa ntchito kwambiri pomanga, milatho, kumanga zombo, ndi nyumba zopepuka zamafakitale.
2. Kodi zinthu zofunika kwambiri za mbale yachitsulo ya ASTM A283 ndi ziti?
Kutha kupotoza bwino komanso kupanga mosavuta
Mphamvu yochepa mpaka yapakati yoyenera kugwiritsidwa ntchito m'mapangidwe opepuka mpaka apakatikati
Yotsika mtengo komanso yotsika mtengo
Ikhoza kuphimbidwa kapena kupakidwa utoto kuti iteteze dzimbiri
3. Kodi mbale yachitsulo ya ASTM A283 ingalumikizidwe?
Inde, imatha kusunthika bwino chifukwa cha mpweya wochepa, yoyenera kusunthika mu MIG, TIG, ndi submerged arc.
4. Kodi mungasankhe bwanji kalasi yoyenera ya mbale yachitsulo ya ASTM A283?
Giredi A: Ntchito zopepuka
Giredi B & C: Kugwiritsa ntchito kapangidwe kake pang'ono
Giredi D: Mphamvu yapamwamba kwambiri mkati mwa A283 ya nyumba zolemera kwambiri
