The production of coiled rebar entails a series of meticulous stages, designed to deliver high-strength, flexible, and weldable reinforcing steel that aligns with industry standards. Beginning with the selection of raw materials and progressing through melting, casting, rolling, cooling, coiling, and final quality control, each phase plays a critical role in achieving the desired product characteristics. The process starts with melting raw materials in an electric arc furnace (EAF) or blast furnace. Scrap steel, iron ore, and alloying elements such as carbon, manganese, silicon, along with microalloying components, are combined and heated to high temperatures to create molten steel with specific mechanical properties. Once the composition is optimized, secondary refining is conducted to eliminate impurities like phosphorus and sulfur, which could compromise the material's strength and ductility. Following this, the purified molten steel is continuously cast into billets, which serve as the starting material for coiled rebar production. These billets are reheated to around 1100–1200°C in a reheating furnace to prepare them for the hot rolling stage. During rolling, the billets pass through a sequence of rollers that gradually reduce their diameter while shaping them into long steel rods. This process ensures consistency in thickness, mechanical properties, and surface finish. Once rolling is complete, a controlled cooling stage is implemented. Depending on the required product characteristics, the steel rods are either cooled on a specialized cooling bed or using a water-cooling system. This step is crucial in enhancing the rods' strength, ductility, and weldability. After achieving the desired temperature and metallurgical properties, the steel rods are fed into a coiling machine that winds them into large coils for ease of transport and storage. The coiling must be monitored carefully to maintain structural integrity and prevent tangling. In the final phase, rigorous quality inspection and testing are performed.
