Dinani batani la kumanja
1. Kusankha Zinthu Zopangira
Miyala yachitsulo yapamwamba kwambiri, chitsulo chotsalira, ndi zinthu zosakaniza monga Cu, Cr, Ni, ndi Si zimasankhidwa kuti zitsimikizire kuti kutentha ndi mphamvu ya makina ndizofunikira.
2. Kupanga Zitsulo (Chosinthira kapena Ng'anjo Yamagetsi)
Zipangizo zopangira zimasungunuka mu chosinthira kapena ng'anjo yamagetsi.
Kuwongolera bwino kapangidwe ka mankhwala kumatsimikizira kukana dzimbiri komanso mphamvu zake zapamwamba.
3. Kuyeretsa Kwachiwiri (LF/VD/VD+RH)
Kuyeretsa ng'anjo ya ladle kumachotsa zinthu zodetsa monga sulfure ndi phosphorous.
Zinthu zosakaniza zimasinthidwa kuti zikwaniritse zofunikira za mankhwala a ASTM A588/A588M.
4. Kuponya Kosalekeza (Kuponya Mapepala Okhala ndi Magalasi)
Chitsulo chosungunuka chimaponyedwa m'ma slabs.
Ubwino wa kuponyera umatsimikizira ubwino wa pamwamba, ukhondo wamkati, ndi kukhazikika kwa kapangidwe ka mbale yomaliza.
5. Njira Yotenthetsera Yotentha
Ma slabs amatenthedwanso ndikukulungidwa mpaka makulidwe ofunikira.
Kuzungulira ndi kuziziritsa kolamulidwa kumaonetsetsa kuti kapangidwe ka tirigu kamakhala kofanana komanso kuti makina ake azikhala olimba.
6. Kupanga Kapangidwe Koziziritsa & Kuzizira
Kuziziritsa bwino (kuzizira mpweya kapena kuzizira mofulumira) kumathandiza kupanga ma microstructures abwino
zomwe zimathandiza kuti pakhale mphamvu zambiri komanso kuti dzimbiri lizigwira ntchito bwino.
7. Kuchiza ndi Kutentha (ngati pakufunika)
Kutengera makulidwe ndi kalasi, mbale zimatha kusinthidwa kapena kusinthidwa
kuti ziwongolere kulimba, kufanana, komanso kukana kukhudzidwa.
8. Chithandizo cha pamwamba
Kuyeretsa pamwamba, kuchotsa makwinya, ndi kuduladula kumachitika.
Pamwamba pa mbaleyo pakonzedwa kuti pakhale utoto, kuphulika, kapena kuwonekera panja popanda vuto lililonse.
9. Kudula, Kulinganiza & Kumaliza
Mapepala achitsulo amadulidwa kutalika ndi m'lifupi mwake.
Kudula m'mphepete, kulinganiza, ndi kuwongolera kusalala kumachitika kuti zikwaniritse kulekerera kwa miyeso.
10. Kuwongolera Ubwino ndi Kuyesa
Mayeso a makina (mphamvu yotulutsa, mphamvu yokoka, kutalika), kusanthula mankhwala,
mayeso okhudza kukhudzidwa, mayeso a ultrasound, ndi kuwunika kwa miyeso kumatsimikizira kuti ASTM A588/A588M ikutsatira malamulo.
11. Kulongedza ndi Kutumiza
Ma mbale amapakidwa ndi njira zopewera dzimbiri (zomangira, zoteteza m'mphepete, zokutira zosalowa madzi)
ndipo zimatumizidwa malinga ndi zosowa za makasitomala.
ASTM A588/A588M ndi chitsulo cholimba kwambiri chotsika (HSLA) chomwe chimadziwika kuti chimalimbana ndi dzimbiri mumlengalenga—chomwe nthawi zambiri chimatchedwa chitsulo chosagwira ntchito. Kutha kwake kupanga utoto woteteza ngati dzimbiri kumapangitsa kuti chigwiritsidwe ntchito panja kwa nthawi yayitali popanda kukonza kwambiri.
1. Milatho ndi Uinjiniya Wanyumba
Amagwiritsidwa ntchito pa mlatho wolimba komanso zinthu zomangira zomwe zimafuna mphamvu zambiri komanso magwiridwe antchito akunja kwa nthawi yayitali.
2. Ntchito Zomanga ndi Kukongoletsa Malo
Zabwino kwambiri pa zokongoletsera zakunja ndi mawonekedwe okongola omwe amapindula ndi mawonekedwe amakono a nyengo.
3. Kumanga Njanji ndi Misewu Yaikulu
Yogwiritsidwa ntchito m'makola, m'mipiringidzo, ndi m'zombo zoyendera zomwe zimafuna kukana dzimbiri mumlengalenga.
4. Zipangizo Zamakampani
Yoyenera matanki, ma chimney, ndi mafelemu amafakitale omwe ali ndi chinyezi komanso nyengo yovuta yakunja.
5. Ntchito Zapamadzi ndi Zam'mphepete mwa Nyanja
Imagwira ntchito bwino m'madoko, m'madoko, ndi m'nyumba za m'mphepete mwa nyanja zomwe zimathiridwa ndi mchere komanso mpweya wonyowa.
6. Makina ndi Zipangizo Zakunja
Amagwiritsidwa ntchito pazida zamakina akunja zomwe zimafuna nthawi yayitali yogwira ntchito komanso kukana kuzizira.
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

Inde.
Imapereka kulimba kwabwino komanso kusinthasintha kwa kutentha.
7. Kodi mbale zachitsulo za ASTM A588 zimafunika malo osungira apadera?
Sungani zouma komanso zopatsa mpweya wabwino.
Kusakhazikika kwa chinyezi kungayambitse dzimbiri losafanana panthawi yoyambirira ya nyengo.
8. Kodi kudula, kupindika, ndi kupanga zinthu mwamakonda kulipo?
Inde—Ma plate a A588 akhoza kudulidwa ndi laser, kudulidwa ndi plasma, kupindika, kulumikizidwa, ndi kupangidwa kutengera mapangidwe a kasitomala.
