1. Kumenyekanisha muri make icyapa cya S355J0W:
S355J0W nicyuma gisanzwe cyu Burayi cyangiza ruswa cyangirika, kikaba ari icyapa cyangiza ikirere. Nicyuma giciriritse gikozwe mukongeramo umubare munini wibintu bivangwa nibyuma bisanzwe. Kurwanya kwangirika kwikirere kwicyuma cyikubye inshuro 2-8 icyuma gisanzwe cya karubone, kandi gifite imiterere yubukanishi, ibikoresho byo gusudira, nibindi, kandi igihe kinini, niko bigaragara ingaruka zo kurwanya ruswa.
2. S355J0W yateje imbere ibyuma birwanya ruswa
Umubare munini wibintu bivangavanze byongewe mubyuma, nka P, Cu, Cr, Ni, Mo, kugirango hongerwe imbaraga zo kurwanya ruswa, kandi bitewe nikirere cy’ikirere, hazongera kubaho okiside ikingira ikingira. icyuma fatizo.
3. Imiterere yo gutanga ya S355J0W:
Yatanzwe muburyo bushyushye, busanzwe cyangwa busanzwe buzunguruka.
Bane, S355J0W icyuma gisanzwe:
S355J0W ishyira mubikorwa EN10025-5: 2004.
5. S355J0W yateje imbere ibyuma birwanya ruswa
Umubare munini wibintu bivangavanze byongewe mubyuma, nka P, Cu, Cr, Ni, Mo, kugirango hongerwe imbaraga zo kurwanya ruswa, kandi bitewe nikirere cy’ikirere, hazongera kubaho okiside ikingira ikingira. icyuma fatizo.
6. Ubushobozi bwacu bwo gutanga:
1. Ikibaho kiboneka cyicyuma cyerekana: uburebure bwa 8-700mm, ubugari 1500-4020mm, uburebure bwa 4000mm-17000mm, uburemere bwibice bigera kuri toni 30.00. Ibyuma binini byo gupima nabyo birahari bisabwe.
2. amasahani yububiko, ibyuma byibyuma byubatswe, Hano hari ibyiciro 12 byibyuma byumuyoboro wa peteroli na gazi, ibyuma bikomeye kandi bikomeye cyane ibyuma, ibyuma birwanya ruswa, hamwe nibyuma, hamwe nibyuma birenga 300 murugo kandi ibirango by'amahanga.
3. Iraboneka kubisabwa kugirango hamenyekane inenge, Z15-Z35 yuburebure bwicyerekezo cyibisabwa, imbaraga nyinshi nibisabwa bikomeye hamwe nibindi byuma.
