Umkhuba wokuthuthuka wenqubo yokuncibilikisa ishubhu yensimbi engenamthungo
Seamless steel ipayipi abakhiqizi ibhizinisi isikali futhi olunzulu
Isilinganiso nokuqiniswa kwabakhiqizi bamapayipi ensimbi angenamthungo sekuphenduke inkambiso, ikakhulukazi ukugcwala kokukhiqizwa kwamapuleti abakhiqizi bensimbi engenamthungo.
Abakhiqizi bamapayipi ensimbi angenamthungo abaphezulu emhlabeni, abaphezulu abayi-10, abakhiqizi bamapayipi ensimbi angenamthungo emhlabeni babalelwa ku-80% wesamba esiphumayo.I-Arcelor phezulu.
Umthamo wensimbi wenkampani, umkhiqizi wamapayipi ensimbi angenamthungo we-krupthyssen, i-otto kupp ne-arcelinox konke kudlula amathani ayizigidi ezi-2
Izinga elikhulu kanye nokuqina kwenkampani ye-sino-arcelor, esifinyelele ezigidini ezingu-3.5 kubakhiqizi bamapayipi ensimbi angenamthungo, kwehlise kakhulu izindleko zokuthengwa nokuncibilikiswa kwezinto ezingavuthiwe.
Umphumela, ukuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo nakho kunezinzuzo ezinkulu.
Kunabakhiqizi bamapayipi ensimbi angenamthungo abangaphezu kwe-16 eChina, ngaphandle kwenani elikhulu lamabhizinisi azimele, amakhulu kunawo wonke e-tiasteel.
Ngaphambi kokuthi umthamo ube yi-1 million t kuphela, i-China iyindawo esetshenziswa kakhulu emhlabeni yabakhiqizi bamapayipi ensimbi angenamthungo.Ngakho-ke, kuyadingeka ukulandela inkambiso yamazwe omhlaba.
Ngokuvumelana nombono wokuthuthukisa imboni yamapayipi ensimbi engenamthungo ye-nanbao beitai, enqunywe umphakathi wamazwe ngamazwe, ukukhiqizwa konyaka kwe-taigang ne-baosteel yizigidi ezingu-2.5 kanye namathani ayizigidi ezingu-1.5 ngokulandelanayo.
Isilinganiso sabakhiqizi bepayipi lensimbi engenamthungo amabhizinisi okukhiqiza insimbi, ukuthuthukisa ukuhlushwa kwabakhiqizi bepayipi lensimbi eChina, bakhuthaze insimbi engenamthungo.
Ukuthuthukiswa okunempilo kwemboni yemboni.
Abakhiqizi bepayipi lensimbi engenamthungo bemishini yokukhiqiza emikhulu
Imishini emikhulu yokukhiqiza yabakhiqizi bamapayipi ensimbi engenamthungo ingenye inkambiso yokuthuthukiswa kwabakhiqizi bamapayipi ensimbi angenamthungo emhlabeni.Ekhulwini lamashumi amabili.
Ngawo-1970s, abakhiqizi beshubhu lensimbi engenamthungo kuphela mayelana nesithando somlilo esingu-50t, isilinganiso sokukhiqiza silinganiselwa ku-300,000 t/a. Ngonyaka ka-2000, isithando somlilo sikagesi kanye
Isithando somlilo se-AOD sikhulu, umthamo wesithando somlilo ufinyelele ku-150t ngaphezulu, isikali sokukhiqiza sifinyelela ku-1 million ta.
Njengamanje, umthamo wesithando somlilo wefekthri yepayipi yensimbi engenasici e-China ayinkulu, kuphela iqembu le-baosteel AOD esithandweni somlilo esingaphezu kwe-100t.Ngakho-ke, i-tisco ne-bao
Umkhiqizi omusha wamapayipi ensimbi angenamthungo uzokwakha izisetshenziswa ezinkulu zokukhiqiza insimbi ukuze kuncishiswe izinga lokukhiqiza ngokubhekisa kumkhuba wamazwe omhlaba wokukhiqiza insimbi ngezinga elikhulu.
Ben, hlangabezana nesidingo semakethe.
Ukunwetshwa kokucaciswa komkhiqizi wamapayipi ensimbi angenamthungo Ukuze kuhlangatshezwane nesidingo semakethe, izicaciso zabakhiqizi bamapayipi ensimbi angenamthungo zilokhu zikhula, ikakhulukazi ububanzi besilebhu bulokhu bukhula njalo.(4) ishubhu lensimbi engenamthungo Izinhlobonhlobo zezinhlobo zefekthri Abakhiqizi baseChina be-nickel kanye nensimbi engenamthungo abakhiqizi bezinsimbi ezilahliwe. imithombo plate.Ukunwetshwa kwefekthri yepayipi lensimbi engenamthungo engu-400 kuzoba ingxenye yefekthri yamapayipi ensimbi engenamthungo eChina.
Elinye lamaphuzu abalulekile okulungiswa kwesakhiwo kwezinhlobonhlobo zasekhaya.Isilinganiso se-Cr – Ni steel to Cr steel emhlabeni ngokuvamile singu-75:25
Isilinganiso siphakeme nakakhulu, 90:10 e-China, kanye 91.3:8.7 e-tisco ngo-2003. Ngakho-ke, ukunwetshwa nokuthuthukiswa kwabakhiqizi bamapayipi ensimbi angenamthungo.
Ukukhiqizwa nokusetshenziswa kuwumsebenzi oyinhloko wabakhiqizi bamapayipi ensimbi angenamthungo e-China.I-Tisco ihlela ukukhiqiza isilinganiso se-Cr - Ni steel to Cr steel ngo-2004.
Ngokuzayo, ingxenye yokukhiqizwa kwensimbi ye-Cr izokwenyuka futhi ngokwenyuka kwesidingo. Ukusetshenziswa kahle kwe-nickel encane noma engekho.
Abakhiqizi abasha bamashubhu ensimbi angenamthungo kanye nabakhiqizi bamashubhu ensimbi angenamthungo wesigaba esiphindwe kabili abakwazi ukunciphisa kuphela izindleko zabakhiqizi bamashubhu ensimbi engenamthungo, kodwa futhi banokubaluleka kwamasu.
Ukuba ingcweti kobuchwepheshe bokukhiqiza bokuncibilika kwalezi zinhlobo zensimbi ukuze kuhlangatshezwane nesidingo semakethe futhi kuwumkhuba wokuthuthukiswa kokukhiqizwa kwensimbi kwabakhiqizi bamapayipi ensimbi angenamthungo eChina.
