Hot Rolled Coil Steel Description
Hot-rolled coil (HRC) steel is a steel made by heating slabs or billets to their recrystallization temperature, typically over 1,000°C, and then rolling them into thin sheets or coils. The use of high-temperature processes makes steel easier and faster to form, with excellent mechanical properties, good surface finish, and cost-effectiveness in practical applications.
Advantages of hot rolled steel coil
1. High strength Hot-rolled steel coils offer exceptional strength, meeting the demands of load-bearing structures and high-stress applications in industries such as construction, automotive, and heavy machinery.
2. Good toughness Excellent toughness, able to withstand shock and dynamic loads, providing durability and reliability even in harsh environments.
3. High dimensional accuracy Advanced manufacturing processes ensure dimensional accuracy, enabling tight tolerances and consistent performance in critical applications.
4. Good board shape Excellent flatness and shape stability, reducing the need for additional straightening or flattening during manufacturing.
5. Smooth surface quality Hot rolled steel coils have a uniform, smooth surface that minimizes defects and improves paint adhesion or coating performance.
Hot rolled coil steel uses
1. Ships
Hot rolled steel coils provide high strength and corrosion resistance in hull, deck and marine structure applications.
2. Car
Used in vehicle chassis, frames and body panels, it provides durability while maintaining lightweight efficiency.
3. Bridge
Its excellent load-bearing capacity and fatigue resistance make it the main material for highway and railway bridge construction.
4. Buildings
Its high strength and weldability enable it to meet the demands of structural frames, beams and columns in high-rise buildings and industrial facilities.
5. Machinery
Durable gears, axles and components for heavy equipment.
6. Pressure vessels
Boilers, tanks and pipes.
Hot rolled steel coil Production process
The production process for hot-rolled steel coils is as follows: after heating the slab to 1200°C, it undergoes rough rolling to remove phosphorus, edge rolling with vertical rollers, and rolling into an intermediate bar in the roughing mill. The bar then undergoes fly shearing to separate the head and tail. It then undergoes finishing rolling to remove phosphorus, followed by seven-stand finish rolling to the target thickness. After laminar cooling and temperature control, the bar is coiled into a coil by a coiler. Finally, finishing processes such as flattening and shearing are performed as needed to produce finished products such as steel plates, flat coils, or slit steel strips.
