hot-rolled steel coil

Hot rolled steel coils are produced by heating a steel billet to a high temperature and then processing it through a rolling process to form a steel plate or coil product of the desired thickness and width.

This process takes place at high temperatures, giving the steel good plasticity and making it easy to shape. Hot rolled steel coils are usually formed into a final flat or coiled product after the billet has been rolled through a series of rolls.
Hot rolling and process

1. Heating: The billet is heated to a high temperature (usually above 1000°C), which gives the steel a large grain structure and good plasticity for forming. 2.

2. Rolling: The heated billet is pressed, crimped and stretched through a rolling mill or roll machine, and gradually pressed into steel plates or coils of the required thickness and width.

3. Cooling and Finishing: After rolling, the steel plate or coil needs to be cooled and finished to improve the surface quality and make it conform to the specifications.

Features and Advantages

1. High Strength: Hot rolled coils have high strength and are suitable for a wide range of structures and applications.

2. good plasticity: steel treated by the hot rolling process has good plasticity, which facilitates subsequent processing and molding.

3. rough surface: the surface of hot rolled coils usually has a certain degree of roughness, which may need to be treated or coated in subsequent processing to improve the appearance and quality.
