Chofoza Inkinobho Kwesokudla
1. Ukukhethwa Kwezinto Ezingavuthiwe
Kukhethwa insimbi esezingeni eliphezulu noma insimbi eqoshiwe ukuqinisekisa ukuthi ukwakheka kwamakhemikhali kuhlangabezana nezidingo ze-ASTM A709.
2. Ukwenza insimbi
Izindlela ze-Basic Oxygen Furnace (BOF) noma i-Electric Arc Furnace (EAF) zisetshenziselwa ukuncibilikisa izinto zokusetshenziswa.
Izinto ezixubayo njenge-manganese, i-silicon, ithusi, i-nickel, ne-chromium ziyangezwa ukuze kufezwe izinga nezakhiwo ezifiselekayo.
3. Ukusakaza
Insimbi encibilikisiwe iphonswa kuma-slab kusetshenziswa izindlela zokuphonswa okuqhubekayo noma izindlela zokuphonswa kwe-ingot.
4. Ukugingqika Okushisayo
Ama-slab ashiswa afike ezingeni lokushisa eliphezulu (~1200°C) bese egoqwa abe amapuleti anobukhulu nobubanzi obudingekayo.
Ukugoqa nokupholisa okulawulwayo kuthuthukisa izakhiwo zemishini njengamandla okukhiqiza nokuqina.
5. Ukwelashwa Ngokushisa (uma kudingeka)
Amanye amazinga (isb., i-HPS) angase ancishiswe futhi ashiswe ukuze kuthuthukiswe amandla, ukuqina, kanye nokushiselwa.
6. Ukwelashwa Kobuso
Amapuleti ayasuswa (ukuphotha, ukuqhuma ngokudubula) ukuze kususwe izingqimba ze-oxide futhi kulungiselelwe ukucutshungulwa noma ukumbozwa okuqhubekayo.
7. Ukusika Nokuqeda
Amapuleti anqunywa ngosayizi ocacisiwe, ahlolwe, futhi ahlolwe izakhiwo zemishini, ukwakheka kwamakhemikhali, kanye nokunemba kobukhulu ngokwezindinganiso ze-ASTM A709.
8. Ukulawulwa Kwekhwalithi Nokuhlolwa
Ipuleti ngalinye lihlolwa kanzima:
Ukuhlolwa kwamandla okunamathela nokukhiqiza
Ukuhlolwa komthelela we-Charpy
Ukuhlolwa kwe-Ultrasonic noma kwe-ultrasonic kokukhubazeka kwangaphakathi
Ukuhlolwa kobukhulu kanye nobuso
9. Ukupakisha Nokulethwa
Amapuleti aqediwe ayahlanganiswa, afakwe ilebula, futhi alungiselelwe ukuthunyelwa kumakhasimende noma ezindaweni zokwakha.
Amapuleti ensimbi e-STM A709 ngokuyinhloko amapuleti ensimbi aqinile kakhulu, angenawo umxube ophansi aklanyelwe ukusetshenziswa emabhulohweni nakwezinye izinhlelo zokusebenza ezisindayo zesakhiwo. Inhlanganisela yawo yamandla, ukuqina, kanye nokushibilika kuwenza afaneleke kakhulu kumaphrojekthi engqalasizinda abalulekile.
