Hot-rolled coil (HRC) is produced through a high-temperature transformation process involving several stages:
Preparation:
The starting material for HRC is typically a steel billet. This semi-finished steel product is a square or rectangular bar heated to a high temperature (often exceeding 1000°C) in a furnace [1, 2]. This high temperature makes the steel more malleable for shaping.
Roughing Mill:
The heated billet is then fed into a series of powerful rollers in the roughing mill. These rollers progressively squeeze and elongate the billet, reducing its thickness and increasing its length into a thinner, longer steel bar [2].
Finishing Mill:
The elongated steel bar from the roughing mill then enters the finishing mill. This mill consists of multiple stands with progressively smaller and smoother rollers. Each stand further reduces the thickness of the steel and refines its surface finish [2, 4].
Coiling:
After passing through the finishing mill, the final hot-rolled steel strip emerges at a desired thickness and width. It's then guided to a run-out table where it's sprayed with water for controlled cooling [3, 4]. Finally, the cooled steel strip is coiled onto a large reel to create the hot-rolled coil (HRC).
Surface Treatment (Optional):
In some cases, the HRC might undergo additional surface treatment processes depending on its final application. This may involve descaling (removing surface oxides) or applying a rust-inhibiting coating [2].
Key points about Hot-Rolled Coil Production:
The entire process occurs at high temperatures, hence the name "hot rolling." This allows for easier shaping of the steel.
Multiple rolling stages progressively reduce thickness and refine the surface finish.
The final product is a long, coiled sheet of steel with a characteristic rougher surface compared to cold-rolled steel.
HRC is a versatile material used in various applications due to its good strength and affordability.
Here's an approximation of current Hot Rolled Coil (HRC) prices in USD per tonne (unless otherwise noted):
US: Prices have been down in 2024. Reports suggest HRC in the US could be around $700-800 per tonne [1].
EU (Northwest Europe): Specific prices aren't readily available, but they've remained stable recently [3].
China: Prices have been dropping due to weak demand. Expect them to be around $550-600 per tonne [2].
Turkey: Prices are facing downward pressure. Expect ex-works offers around $620-640 per tonne and domestic prices around $680-700 per tonne [4].
Important Note: Steel prices can fluctuate depending on factors like grade, thickness, quantity, and negotiation. These are just general ranges to give you an idea.
HRC prices can vary significantly based on thickness. Here's a breakdown of estimated pricing (USD per tonne) for different thicknesses in each region:
Region Thickness (mm) Price Range (USD/tonne)
US 2-3mm $750-850
US 4-6mm $700-800
EU 2-3mm Not available (likely similar range to US)
EU 4-6mm Not available (likely similar range to US)
China 2-3mm $600-650
China 4-6mm $550-600
Turkey 2-3mm $650-700 (ex-works) / $700-750 (domestic)
Turkey 4-6mm $620-640 (ex-works) / $680-700 (domestic)

Key Points:
Thinner HRC (2-3 mm) generally commands a premium due to the additional processing involved.
Prices are estimates and can vary based on factors like grade, quantity, and negotiation.
Specific pricing information for EU is difficult to find publicly, so the US range is used as a possible reference.
