Hot Rolled Coil

What Is Hot Rolled Coil

Hot rolled coil is a type of steel produced through a high-temperature rolling process, often exceeding 1000 degrees Celsius. It is made of slab (mainly continuous casting billet) as raw material. After heating,itis m ade into strip steelby the rough rolling mill and the finishing mill.The hot steel strip from the last roling mill of finishing roling is cooled to a set temperature by laminar flow,and then coiled into a steel strip coil by a coiler, and the cooled steel strip coil.

Characteristics Of Hot Rolled Coil

Hot rolled coils are usually used in construction and manufacturing.
Hot rolled coils are made at higher temperatures, making them easier to use.The hot rolled coil can also withstand high defects and is not easy to warp or crack in the manufacturing process.

The Advantage

High strength, good toughness, easy processing and forming, good weldability, raw materials after heating thermoplasticity, deformation resistance is reduced, so the amount of deformation can be increased during rolling, which is conducive to improving production efficiency.

The Shortcoming

High temperature rolling produces oxide sheet, the metal surface finish is poor, the dimensional accuracy of the product is not high, and the mechanical properties are not as good as cold processing.

Choosing The Appropriate Hot Rolled Steel Coil

When selecting hot-rolled coils for your project, it is important to consider the materials you will use. Hot rolled steel coils have different grades, and each brand has different characteristics and uses.

For example, lower grades, such as commercial quality or drawing quality, may be more suitable for projects that do not require high strength or durability, such as light metal sheet manufacturing.Higher grades, such as structural quality or pressure vessel quality, are usually used in heavier applications such as welding or structural construction.

It is also important to consider the size and shape of the hot-rolled coil required for the project. Hot rolled coils have different widths and thicknesses, so choosing the right type is crucial to the current task.

Finally, when making a decision, you should also consider the cost of hot-rolled coil.Compared with cold-rolled coil, the cost of hot-rolled coil is usually lower.They are multi-purpose, cost-effective iron and steel products that can be used in a variety of applications.The hot rolling process provides many benefits, including increased strength, improved ductility and reduced cracking.


Understanding the basics and advantages of hot rolled coil will help you make an informed decision about what kind of steel to use in the next project.Hot rolled coil has many advantages and is an excellent choice for any application that requires reliable results at an affordable price.
