Amakuru - Amashanyarazi ashyushye ya Steel: nyamukuru yinganda zinganda

In the modern industrial system, hot-rolled steel coils are basic materials, and their diversity of models and performance differences directly affect the development direction of downstream industries. Imyambarire itandukanye ya coil ishyushye amashina zishyushye mumirima yubwubatsi, imodoka, imbaraga, nibindi hamwe nibigize imiti yabo idasanzwe hamwe nububiko bwimico. Ibikurikira bizibanda ku gusesengura imiti ishyushye yijimye hamwe nisoko ryisoko ryisoko ryisoko ryibanze.

Imbaraga nyamukuru: Q235B na SS400
Q235B nicyo gikoreshwa cyane-karubone yubushinwa mubushinwa, hamwe na karubone muri 0.12% -00%, kandi ifite plastike nziza no gutangara. Imbaraga zayo zitanga ≥235MPA kandi zikoreshwa cyane mukubaka amakadiri, ikiraro gishyigikira hamwe nibice rusange bya mashini. Mu nganda zubwubatsi, i-cyuma, imiyoboro yimiyoboro nibindi bimera bikozwe muri Q235B ibara rya coils zirenga 60%, rishyigikira skeleti yibikorwa remezo byo mumijyi.
SS400 ni ibyuma byimiryango yimbere hamwe nimbaraga zisa na Q235b, ariko kugenzura gukomeye kwa sulfuru na fosifore hamwe nubwiza bukomeye. Mu murima wo kubaka ubwato, SS400 ishyushye-ishyushye rimwe na rimwe ikoreshwa mu bice byimiterere. Kurwanya kwamazi byacyo biruta ibyuma bisanzwe bya karubone, kubungabunga umutekano wurugendo rwinyanja.

Abahagarariye imbaraga nyinshi: Q345B na Q960
Q345b ni hasi-amadolari-imbaraga-zisumbuye hamwe na 1.0% -1,6% mangase yongeyeho, kandi imbaraga zitanga hejuru ya 345mpa. Ugereranije na Q235b, imbaraga zayo ziyongereyeho 50%, mugihe ukomeje gushobora gushobora gucogora. Muri ikiraro cyubuhanga, agasanduku gasanduku gakorerwa Q345B coils zishyushye zishyushye zirashobora kugabanya ibiro kuri 20%, kugabanya ibiciro byubwubatsi. Muri 2023, kubaka ikiraro cyo murugo bizakoresha toni zirenga miliyoni 12 za Q345B ishyushye abapolisi, ibaruramari rya 45% byumurongo wose wubu bwoko.
Nkumuntu usanzwe uhagarariye ibyuma bya ultra-byinshi, Q960 agera ku mbaraga zitanga ≥960mpa binyuze muri tekinoroji ya MicroalIng (yongeyeho igitsina, Titanium hamwe nibindi bintu) kandi bigenzurwa na fagitire yo kuzunguruka no kugenzurwa. Mu murima w'imashini z'uburango, ubunini bw'ukuboko kwa Crane bikozwe muri Q960 ashyushye ya Q960, kandi ubushobozi bwo gutwara imitwaro bwiyongereyeho inshuro 3, biteza imbere kuzamura ibikoresho nkacuragurira no gucukura.

Ibipimo bidasanzwe: SPHC na Saph340
SPHC nigicuruzwa cyanduza cyane mubice bishyushye-bishyushye-bya karubone. Mugutezimbere inzira izunguruka kugirango igenzure ingano yingano, kurengerwa bigera kuri 30%. Mu nganda zifatika zo murugo, sphc zishyushye zikoreshwa mugukora ibisabwa na firigo ya firigo. Imikorere yayo yimbitse iremeza ko igipimo cyujuje ibyangombwa byurubuga runini rugizwe na 98%. Muri 2024, kunywa sphc bishyushye-bishyushye munzu yo murugo murugo biziyongera kugeza kumyaka 15% yumwaka-ukomoka kumyaka-miliyoni.
Nkicyuma cyimodoka, Saph340 igera ku buhinzi hagati y'imbaraga n'ubugari wongeyeho 0.15% -0.25% karubone na trace Boron. Mugukora ibinyabiziga bishya bya bateri yibinyabiziga, Saph340 ashyushye ya STHILS irashobora kwihanganira imitwaro irenze 500mpa kandi yujuje ibisabwa kugirango ubone inzira yo gusudira. Muri 2023, igipimo cya coils-yazungurutse ubushyuhe bwubu bwoko bwakoreshejwe mumodoka nshya yo murugo yageze kuri 70% yibice bya bateri.

Icyitegererezo	Imbaraga Zitanga Imbaraga (MPA)	Kurambagiza (%)	Ibisanzwe bisanzwe
Q235b	≥235	≥26	Kubaka Inzego, Imashini Rusange
Q345B	≥345	≥21	Ikiraro, ibikoresho byigituba
Sphc	≥275	30	Ibikoresho byo murugo, ibice byimodoka
Q960	≥960	≥1	Imashini yububiko, ibikoresho byo hejuru
