Dib-u-eegistii Shiinaha uu hoggaamiyo ee heerarka caalamiga ah ee berrinkii taarikada birta iyo strips ayaa si rasmi ah loo daabacay

Heerka waxaa loo soo jeediyay dib u eegis sanadka 2022 shirka sanadlaha ah ee ISO/TC17/SC12 Steel/Continuly Rolled Flat Products Guddi-hoosaadka, waxaana si rasmi ah loo bilaabay March 2023. Kooxda shaqo diyaarinta waxay socotay laba sano iyo badh, inta lagu guda jiro kaas oo hal kulan koox shaqo iyo laba kulan sanadle ah ayaa loo qabtay doodo aad u daran, iyo 25 April daabacaadda lixdii ISO 4997:2025 "Darajada Dhisme ee Qabow duuban Kaarboon saxan khafiif ah" ayaa la keenay.

Halbeeggani waa dib-u-eegis kale oo caalami ah oo uu hoggaaminayo Shiinaha ka dib markii Shiinuhu la wareegay guddoomiyenimada ISO/TC17/SC12. Siideynta ISO 4997: 2025 waa horumar kale oo ka qaybqaadashada Shiinaha ee shaqada halbeegga caalamiga ah ee berrinka taarikada birta iyo xargaha ka dib ISO 8353: 2024.

Kaarboon qaab dhismeedka birta qabow duuban saxan bir ah iyo alaabada xariijimaha ah waxaa ka go'an in ay wanaajiyaan xoogga iyo yaraynta dhumucda, si ay u yareeyaan miisaanka alaabta dhamaadka, gaaritaanka yoolka ugu dambeeya ee badbaadinta tamarta iyo dhimista qiiqa, iyo xaqiijinta fikradda wax soo saarka ee "birta cagaaran". Nooca 2015 ee heerka wax-soosaarka aadka loo isticmaalo suuqa ee 280MPa darajooyinka birta ah lama cayimin. Intaa waxaa dheer, waxyaabaha ku jira farsamada ee heerka, sida qallafsanaanta dusha sare iyo miisaanka dufcada, ma buuxinayaan baahida dhabta ah ee wax soo saarka hadda. Si loo sii wanaajiyo ku-dhaqanka heerka, Machadka Cilmi-baarista Heerarka Macluumaadka Warshadaha Metallurgical ayaa abaabulay Anshan Iron & Steel Co. si ay u codsadaan mashruuc shaqo oo heer caalami ah oo cusub oo loogu talagalay alaabtan. Nidaamka dib u eegista, shuruudaha farsamada ee darajada cusub ayaa lagu go'aamiyay iyada oo lala tashanayo khabiiro ka socda Japan, Jarmalka iyo Boqortooyada Ingiriiska marar badan, iyagoo ku dadaalaya in ay buuxiyaan shuruudaha wax soo saarka iyo kormeerka waddan kasta iyo ballaarinta baaxadda codsiga ee jaangooyooyinka. Siideynta ISO 4997: 2025 "Grade Qaab-dhismeedka Qabow-Rolled-Rolled Carbon Thin Steel" ayaa ku riixay cilmi-baarista Shiinaha ee cusub.
