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.

1. Ukupakishwa Kwenqwaba Ehlanganisiwe
Amapuleti ensimbi ahlelwa futhi abekwe kahle ngokwesayizi nezincazelo ezahlukene. Izihlukanisi zokhuni noma zensimbi zifakwa phakathi kwesendlalelo ngasinye ukuze kugcinwe amapuleti ethe tyaba, kugwenywe ukuthintana ngqo futhi kuvinjelwe umonakalo wokungqubuzana komhlaba. Zonke izinqwaba ezibekwe ziboshwe ngokuqinile ngezintambo zensimbi ukuqinisekisa ukuzinza okuphelele ngesikhathi sokuhamba futhi kugwenywe ukugudluka noma ukukhululeka.
2. Ukupakishwa Kwebhokisi Nephalethi
Amapuleti ensimbi amancane nasezingeni eliphezulu asebenzisa izixazululo zokupakisha zebhokisi lokhuni noma zephalethi. Iphepha elivikela ukugqwala kanye nefilimu yepulasitiki kufakwe ngaphakathi kwamaphakeji ukuze kuvikelwe umswakama nokugqwala. Le ndlela ejwayelekile yokupakisha yokuthumela ngaphandle yenza kube lula ukulayisha, ukulayisha kanye nokuphathwa kwempahla yokugcina impahla, futhi ivumelana ngokugcwele nokuthuthwa kwamanye amazwe kanye nokugcinwa kwamanye amazwe isikhathi eside.
3. Ukupakisha Ukuthunyelwa Okukhulu
Amapuleti ensimbi amakhulu kakhulu namakhulu alethwa ngobuningi ngezokuthutha zasemanzini noma emhlabeni. Amabhulokhi e-cushion okhuni nezinto zokuzivikela zobungcweti zisetshenziswa ezindaweni zokuthintana kwamapuleti. Lokhu kuvimbela ngempumelelo ukuphuma nokushayisana ngesikhathi sokuthuthwa, kuvikela ubuso bepuleti lensimbi kanye nokuqina kwesakhiwo sonke.
Ukubambisana okuzinzile nezinkampani zokuthumela izimpahla ezifana ne-MSK, i-MSC, i-COSCO, uchungechunge lwezinsizakalo zezokuthutha olusebenza kahle, kanye nochungechunge lwezinsizakalo zezokuthutha kuzokwenza ukwaneliseka kwakho.
Silandela amazinga ohlelo lokuphatha ikhwalithi i-ISO9001 kuzo zonke izinqubo, futhi sinokulawula okuqinile kusukela ekuthengweni kwezinto zokupakisha kuya ekuhleleni izimoto zokuthutha.
1. KuyiniIpuleti lensimbi le-ASTM A709?
