Caafimaadka Rebar Qof Kasta | Steel Rebar Dhulka ah ee Construction

Ku cariista rebar waxaa ugu yaraa shisheeyada dhammaan la xiriiraalka ah oo ka mid ah carruurta billets ee steel raw, ku jirin macluumaadka metallurgical iyo engineering caddeed. Shacabka ahaa carruurta billet (1,100–1,200°C) fiirfiiqda reheating furnaces, si aad uga soo dirir kartaa hot rolling kala duwan stands marka hore ee ku jira diameter iyo rib pattern dheeraad ah, ku muuqata standards kale oo la sameyn doono ASTM A615, EN 10080, ama GB/T 1499.2. Si aan u baahnaa grades ee ku jiro strength la'aan, thermo mechanical treatment (TMT) waa inuu ka socdo: cooling carruurta ah marka hore ee ku jira hardened qof outer iyo core ductile, ku saabsan yield strength by 20–30%. Labs ee quality control waxay ugu yarayn testing caddeed: chemical analysis (inductively coupled plasma spectroscopy), tensile testing (marka hore offset yield strength measurement 0.5%), iyo bend testing (180° carruurka ah ee ku jiro mandrel diameter equal to 3D for 25mm rebars). Ku cariistayaash waxay ku yarayn portfolio ee product diverse: carbon steel rebars (235–400 MPa), microalloyed rebars (400–600 MPa), iyo specialty products (stainless steel rebars marin structures, epoxy coated rebars nuclear facilities). Certifications kale ISO 9001, CE, iyo API (for oil country rebars) waxay joogto standard, marka hore traceability systems waxay ugu yarayn tracking heat lot kasta oo dhan from billet to finished product. Innovation ayaa ka dhintay focus on developing rebars higher ductility seismic zones (Agt ≥12%) iyo eco friendly coatings (zinc aluminum alloys with 30% less zinc usage), si aad uga soo jeedo global sustainability goals while meeting demand ee ku jira resilient infrastructure.
