How is Chinese hot-rolled steel plate suitable for infrastructure projects in Central America?A complete analysis of key grades such as Q345B

I-hot-rolled steel plate: Izibaluli eziyinhloko zetshe legumbi lemboni
Ipuleti lensimbi eligoqelwe ngokushisayoyenziwe ngamabhilidi ngokusebenzisa izinga lokushisa eliphezulu. Inezinzuzo ezibalulekile zokuguquguquka kwamandla okubanzi kanye nokwakheka okuqinile, okuyenza isetshenziswe kabanzi ekwakhiweni kwezakhiwo, ingqalasizinda, ukwenziwa kwemishini, neminye imikhakha.

Ngokusho kwedatha evela ku-Latin American Steel Association, ukuthengwa kwensimbi yase-Central America kwenza u-11% wesamba esiphelele saseLatin America, ingxenye yakhona ivela e-China.

Izinto ezibalulekile ezithengwe e-China e-Central America kanye nezicelo zazo

(I) I-alloy ephansi, insimbi enamandla amakhulu: Q345B
I-Q345B iyinto "okufanele ube nayo" yamaphrojekthi wengqalasizinda yaseMelika Emaphakathi. Ngamandla okukhiqiza angu-345 MPa, ihlanganisa ukushisela okuhle kakhulu kanye nokumelana nomthelela. Ihambisana namazinga e-GB/T futhi inesitifiketi se-ISO9001.

Emaphrojekthini amabili amakhulu okunwetshwa kwamapayipi endle eNicaragua, kwathengwa amathani angu-1,471.26 ezinqwaba zamashidi ensimbi e-Larsen agingqiwe ashisayo e-Q345B ngesikhathi esisodwa. Lezi zasetshenziselwa ukwakhiwa kwesisekelo samapayipi endle angamakhilomitha angama-87.2, iziteshi zokupompa indle ezinhlanu, kanye nendawo yokukhuculula indle eyodwa. Atholakala ngobude obuyi-9m, 12m, kanye no-15m, afanelana kahle nokujula okudingekayo kwephrojekthi engaphansi komhlaba. Inzuzo eyinhloko yale nto ukusimama kwesakhiwo endaweni eshisayo, enezimvula, kuyilapho inikeza isilinganiso samanani sokusebenza esidlula kude leso semikhiqizo yasendaweni efanayo.

(II) Insimbi Yesakhiwo Sekhabhoni Esezingeni Eliphezulu: SPHT1 kanye nochungechunge lwe-SAE

I-SPHT1: Njengensimbi yokugxiviza ngaphansi kwezinga laseJapane le-JIS, i-SPHT1 isiphenduke into ekhethwayo yokwakha ingqalasizinda e-Dominican Republic ngenxa yokuqina kwayo kwepulasitiki nokuqina. I-Royal Steel ngaphambilini yenza ngokwezifiso amathani angu-900 wekhoyili egoqelwe eshisayo ye-SPHT1 yeklayenti laseDominican. Ngemva kokuthuthukisa amapharamitha wokugxiviza nokuqhubeka nokucutshungulwa kube amapayipi, i-SPHT1 yasetshenziswa ekwakhiweni kwamapayipi asemadolobheni. Amandla ayo alinganiselayo kanye nokwakheka kwawo kuyenze yafanelekela izidingo ezivamile zokubeka amapayipi eMelika Ephakathi.

I-SAE 1006/1008: Lezi zinsimbi ezimbili ezinekhabhoni eshisayo ezigoqekayo ziyizinto ezibalulekile zokukhiqiza izingxenye zesakhiwo ezingasindi. I-Royal Steel Group yake yathumela ngaphandle kwamathani ayi-14,000 amakhoyili ashisayo e-SAE 1008 eBrazil.

(III) I-Weathering Structural Steel: A588 Gr B
Insimbi yesimo sezulu i-A588 Gr B, enongqimba lwayo lokugqwala oluziphilisayo, izuze isabelo semakethe kumswakama ophezulu kanye nezindawo ezigqwala kakhulu ezitholakala ezingxenyeni ze-Central America.
I-Mexico yake yangenisa amathani angu-3,000 amapuleti ensimbi agingqiwe ashisayo e-A588 Gr B enkampanini yethu ukuze asetshenziswe ekwakhiweni kwebhuloho elingasogwini nokwakhiwa kwengqalasizinda yamachweba.

(IV) I-General-Purpose Carbon Steel: I-SS400 kanye ne-ASTM A36 Basic Supplies
SS400 (okujwayelekile Japanese) kanyeI-ASTM A36(Izinga laseMelika) "liyizinto ezisetshenziswayo ezibalulekile" embonini yaseMelika Ephakathi. Ngamandla esivuno angu-245 MPa kanye nama-MPa angu-250, ngokulandelana, afanele izingxenye zesakhiwo ezinomthwalo ophansi kanye nokukhiqizwa kwemishini evamile. Amakhasimende ase-Colombian e-Royal Steel Group athenga ngokuyinhloko amapuleti ensimbi anephethini angu-3.0mm enziwe nge-SS400 ukuze asetshenziswe ezimelene nokushelela ezinkundleni zokuhamba nezokwakha.

I-Royal Steel Groupinikeza izinsiza "zokwenza ngokwezifiso + ukulethwa okusheshayo", okusiza ukubhekana nezinhlelo eziqinile zamaphrojekthi eMelika Ephakathi.

Izintengo zokuthekelisa zamapuleti ensimbi agingqiwe e-China aphansi ngo-15% -20% kunalawo ase-Europe nase-United States. I-Royal Steel Group, enekomkhulu e-Tianjin, inamanethiwekhi okuthutha asuka e-Tianjin Port nase-Shanghai Port, efinyelela ezindaweni ezinkulu ezifana ne-Nicaragua ne-Mexico, futhi inciphisa izindleko zokuthenga.

Siyayamukela ngobuqotho imibuzo nokusebenzisana okuvela ezinkampanini zengqalasizinda, abakhiqizi bemishini, nozakwethu bokuhweba e-Central America nasemhlabeni jikelele! Kungakhathaliseki ukuthi amamaki avuthiwe, ajwayelekile njenge-Q345B ne-SPHT1, noma imikhiqizo eyenziwe ngokwezifiso efana ne-A588 Gr B yensimbi yesimo sezulu kanye nensimbi enamandla kakhulu engu-Q420B, i-Royal Steel Group inikeza isevisi yokuma okukodwa, okuhlanganisa ukuklama kwesixazululo sobuchwepheshe esisodwa, ukulethwa kwesampula kwamahhala, nokulandelela okugcwele komkhumbi olwandle, ukusiza amaphrojekthi akho ukufeza ukuncishiswa kwezindleko ngesikhathi, ukuthuthukiswa kwezindleko, ukuthuthukiswa kwesikhathi. Sibheke ngabomvu ukusebenzisana nawe ukwakha ipulani entsha yokuthuthukiswa kwezimboni nengqalasizinda eMelika Ephakathi!
