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

Isahani ishyushye isahani: Ibyingenzi biranga inganda zinganda
Isahani ishyushyeikozwe muri bilet ikoresheje ubushyuhe bwo hejuru. Ifite ibyiza byibanze byimbaraga nini zijyanye no guhuza n'imihindagurikire ikomeye, bigatuma ikoreshwa cyane mubikorwa byubaka, ibikorwa remezo, gukora imashini, nizindi nzego.

Dukurikije imibare yaturutse mu ishyirahamwe ry’ibyuma byo muri Amerika y'Epfo, ibyuma byo muri Amerika yo Hagati bitumiza mu mahanga bingana na 11% by'Abanyamerika y'Epfo, kimwe cya kabiri kiva mu Bushinwa.

Ibikoresho by'ingenzi byaguzwe mu Bushinwa muri Amerika yo Hagati n'ibisabwa

(I) Ibyuma-bivanze, ibyuma-bikomeye: Q345B
Q345B nigikoresho "kigomba-kugira" imishinga yibikorwa remezo byo muri Amerika yo Hagati. Hamwe nimbaraga zitanga 345 MPa, ikomatanya gusudira neza no kurwanya ingaruka. Yubahiriza ibipimo bya GB / T kandi byemewe ISO9001.

Mu mishinga ibiri minini yo kwagura imiyoboro y’imyanda muri Nikaragwa, toni 1,471.26 zose za Q345B zishyushye zishyushye za Larsen z'ibyuma byaguzwe icyarimwe. Ibi byakoreshejwe mu kubaka umusingi wa kilometero 87.2 z'imiyoboro y’imyanda, sitasiyo eshanu zivoma, n’uruganda rumwe rutunganya imyanda. Biboneka muri 9m, 12m, na 15m z'uburebure, bihuye neza nuburebure bukenewe bwumushinga wubutaka. Inyungu yibanze yibi bikoresho ni imiterere yimiterere yimiterere yubushyuhe, imvura igwa, mugihe itanga igiciro-cyimikorere irenze kure ibyo bicuruzwa byaho.

SPHT1: Nkicyuma kashe munsi yu Buyapani JIS, SPHT1 yahindutse ihitamo ryubwubatsi bwibikorwa remezo muri Repubulika ya Dominikani kubera plastike nini kandi ikomeye. Royal Steel yabanje gutunganya toni 900 za SPHT1 zishyushye zishyushye kubakiriya ba Dominikani. Nyuma yo guhitamo kashe ya kashe no gukomeza gutunganya imiyoboro, SPHT1 yakoreshejwe mukubaka imiyoboro yo mumijyi. Imbaraga zuzuye hamwe nuburyo byashobokaga byatumye bikenerwa muri Amerika yo Hagati.

SAE 1006/1008: Ibi byuma bibiri bya karuboni nkeya bishyushye ni ibikoresho byingenzi byo gukora ibice byubaka byoroheje. Royal Steel Group yigeze kohereza toni 14,000 za SAE 1008 zishyushye zishyushye muri Berezile.

(III) Ikirere cyubaka ibyuma: A588 Gr B.
A588 Gr B ikirere cyikirere, hamwe nikigero cyacyo cyo kwikiza ingese, cyabonye isoko kumasoko menshi yubushyuhe bwinshi nibidukikije byangirika cyane biboneka mubice bya Amerika yo Hagati.
Mexico yigeze gutumiza toni 3.000 za A588 Gr B ibyuma bishyushye bishyushye mu kigo cyacu kugirango bikoreshwe mu kiraro cyo ku nkombe no kubaka ibikorwa remezo by’ibyambu.

(IV) Rusange-Intego ya Carbone Icyuma: SS400 na ASTM A36 Ibikoresho Byibanze
SS400 (Ikiyapani gisanzwe) naASTM A36(Igipimo cyabanyamerika) ni "ibintu byingenzi bikoreshwa" mu nganda zo muri Amerika yo Hagati. Hamwe n'imbaraga z'umusaruro wa 245 MPa na 250 MPa, zikwiranye nibikoresho bito byubatswe buke hamwe no gukora imashini rusange. Abakiriya ba Royal Steel Group bo muri Kolombiya bagura cyane cyane 3.0mm yicyuma gikozwe mubyuma bikozwe muri SS400 kugirango babashe kurwanya kunyerera mu bwikorezi no mu bwubatsi.

Itsinda ryubwamiitanga serivisi "yihariye + itanga byihuse", ifasha gukemura gahunda ihamye yimishinga muri Amerika yo Hagati.

Ibicuruzwa byoherezwa mu byuma by’Ubushinwa biri hasi ya 15% -20% ugereranije n’ibihugu by’Uburayi na Amerika. Royal Steel Group, ifite icyicaro i Tianjin, ifite imiyoboro yo kohereza ibicuruzwa biva ku cyambu cya Tianjin no ku cyambu cya Shanghai, igera ahantu hanini nka Nikaragwa na Mexico, bikagabanya ibiciro by’amasoko muri rusange.

Twishimiye byimazeyo ibibazo nubufatanye bituruka mubigo remezo, abakora imashini, nabafatanyabikorwa mubucuruzi muri Amerika yo Hagati no kwisi yose! Yaba ibyiciro bikuze, ibyiciro byingenzi nka Q345B na SPHT1, cyangwa ibicuruzwa byabigenewe nka A588 Gr B ibyuma byikirere hamwe na Q420B ibyuma bikomeye cyane, Royal Steel Group itanga serivise imwe, harimo igishushanyo mbonera cya tekiniki, gutanga icyitegererezo kubuntu, hamwe no kohereza ibicuruzwa byuzuye mu nyanja, kugirango bifashe imishinga yawe kugera kubiciro, kunoza imikorere, no kurangiza mugihe gikwiye. Dutegereje kuzakorana nawe kubaka igishushanyo mbonera gishya cyo guteza imbere inganda n'ibikorwa remezo muri Amerika yo Hagati!
