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

Ipleyiti yentsimbi eshushu eqengqelekayo: Iimpawu eziphambili zelitye lembombo kwishishini
Ipleyiti yentsimbi eshushuyenziwe kwiibhilithi ngokuqengqeleka kobushushu obuphezulu. Iqhayisa ngezona nzuzo ziphambili zokuguquguquka kwamandla abanzi kunye nokwakheka okuqinileyo, kuyenza isetyenziswe ngokubanzi kwizakhiwo zokwakha, iziseko ezingundoqo, ukwenziwa koomatshini, kunye namanye amacandelo.

Ngokutsho kwedatha evela kwi-Latin American Steel Association, i-Central America ye-steel ingenisa i-11% ye-Latin America iyonke, isiqingatha sayo sivela e-China.

Izinto eziphambili ezithengiweyo eChina kuMbindi Merika kunye nokusetyenziswa kwazo

(I) I-alloy ephantsi, intsimbi ephezulu: Q345B
I-Q345B yinto "ekufuneka ube nayo" kwiiprojekthi zeziseko zophuhliso kuMbindi waseMelika. Ngamandla esivuno se-345 MPa, idibanisa i-weldability egqwesileyo kunye nokumelana nempembelelo. Ihambisana nemigangatho ye-GB/T kwaye iqinisekisiwe nge-ISO9001.

Kwiiprojekthi ezimbini ezinkulu zokwandiswa kwemibhobho yogutyulo eNicaragua, iyonke ye-1,471.26 yeetoni ze-Q345B ezigutyungelwe ngokushushu ze-Larsen sheet sheet sheets zathengwa ngexesha elinye. Ezi zisetyenziselwe ulwakhiwo olusisiseko lweekhilomitha ezingama-87.2 zemibhobho yogutyulo, amaziko okumpompa amahlanu, kunye neziko elinye lokucoca ugutyulo. Zifumaneka kwi-9m, 12m, kunye ne-15m ubude, zihambelana ngokugqibeleleyo nobunzulu obufunekayo beprojekthi ephantsi komhlaba. Inzuzo engundoqo yesi sixhobo kukuzinza kwesakhiwo kwiindawo ezitshisayo, kwimozulu yemvula, ngelixa inika umlinganiselo wexabiso lokusebenza ogqithise kakhulu kwiimveliso zasekhaya ezifanayo.

(II) I-High-Quality Carbon Structural Steel: SPHT1 kunye ne-SAE Series

I-SPHT1: Njengesitampu sentsimbi phantsi komgangatho we-JIS yaseJapan, i-SPHT1 iye yaba yinto ekhethiweyo yokwakhiwa kwezakhiwo kwiRiphabhliki yaseDominican ngenxa yeplastiki ephezulu kunye nokuqina. I-Royal Steel ngaphambili yayilungelelanise iitoni ezingama-900 ze-SPHT1 yekhoyili eshushu eqengqelekayo kumthengi waseDominican. Emva kokuphucula iiparamitha zesitampu kunye nokuqhubekeka phambili kwimibhobho, iSPHT1 yasetyenziswa kulwakhiwo lwemibhobho yasezidolophini. Amandla ayo alungeleleneyo kunye nokwakheka kwawo kuyenze yafaneleka kwiimfuno zokubekwa kwemibhobho rhoqo kuMbindi Merika.

I-SAE 1006/1008: Ezi zintsimbi zimbini ziphantsi kwekhabhoni eshushu ziqengqeleka zizinto ezingundoqo zokwenza izinto ezilula. I-Royal Steel Group yakha yathumela ngaphandle kwe-14,000 yeetoni ze-SAE 1008 iikhoyili eziqengqelekayo e-Brazil.

(III) iWeathering Steel: A588 Gr B
I-A588 Gr B yentsimbi yemozulu, enomaleko wayo okwazi ukuziphilisa, iye yazuza isabelo semarike kubumanzi obuphezulu kunye neendawo ezinobume obuphezulu ezifumaneka kwiindawo zoMbindi Merika.
I-Mexico yakha yathenga kumazwe angaphandle i-3,000 yeetoni ze-A588 Gr B zentsimbi ezishushu eziqengqelekayo kwinkampani yethu ukuze zisetyenziswe kwibhulorho engaselunxwemeni kunye nokwakhiwa kweziseko zophuhliso lwezibuko.

(IV) iSitali seCarbon yeNjongo ngokubanzi: i-SS400 kunye ne-ASTM A36 yeeMbonelelo ezisisiseko
SS400 (umgangatho Japanese) kunyeI-ASTM A36(umgangatho waseMelika) "zizinto ezityiwayo ezibalulekileyo" kuMbindi waseMelika. Ngamandla esivuno se-245 MPa kunye ne-250 MPa, ngokulandelanayo, zifanelekile kumthwalo ophantsi wezakhiwo kunye nokuveliswa koomatshini ngokubanzi. Abathengi baseColombia beRoyal Steel Group bathenga ngokuyintloko iipleyiti zentsimbi ezinomfanekiso we-3.0mm ezenziwe nge-SS400 ukwenzela izicelo ezichasene nokutyibilika kwezothutho kunye namaqonga okwakha.

Iqela leRoyal Steelinikeza "ukwenza ngokwezifiso + ukuhanjiswa ngokukhawuleza" iinkonzo, ezinceda ukujongana neeshedyuli eziqinileyo zeeprojekthi kuMbindi Melika.

Amaxabiso athunyelwa ngaphandle kwentsimbi eshushu aqengqelekayo eTshayina aphantsi nge-15% -20% kunalawo aseYurophu nase-United States. Iqela laseRoyal Steel, elinekomkhulu eTianjin, liqhayisa ngothungelwano lwenqanawa olusuka eTianjin Port kunye neShanghai Port, lufikelela kwiindawo eziphambili ezifana neNicaragua neMexico, lunciphisa ngakumbi iindleko zokuthenga.

Siyayamkela ngokunyanisekileyo imibuzo kunye nentsebenziswano evela kwiinkampani zeziseko zophuhliso, abavelisi boomatshini, kunye namaqabane orhwebo kuMbindi Merika nakwihlabathi liphela! Ingaba ikhulile, amabanga aqhelekileyo afana ne-Q345B kunye ne-SPHT1, okanye iimveliso ezenziwe ngokwezifiso ezifana ne-A588 Gr B yensimbi yemozulu kunye ne-Q420B yentsimbi ephezulu, iRoyal Steel Group inikezela ngeenkonzo zokumisa enye, kubandakanywa uyilo lwesisombululo sobugcisa, ukuhanjiswa kwesampuli yamahhala, kunye nokulandelela okupheleleyo kolwandle, ukuncedisa iiprojekthi zakho, ukufezekisa ukuphumelela kunye nokunciphisa iindleko ngexesha lokunciphisa, ukuphuculwa kweendleko kunye nokuphucula ixesha. Sijonge phambili ekusebenzeni nawe ukwakha iplani entsha yophuhliso lweshishini kunye neziseko zophuhliso kuMbindi Merika!
