Detailed explanation of hot rolled steel coils

Hot-rolled steel coil is a steel plate or steel coil product that is heated to a high temperature and then processed into a steel plate or steel coil product of the required thickness and width through a rolling process.

Hot rolling and process

1. Heating: The steel billet is heated to a high temperature (usually above 1000°C), which makes the grain structure of the steel larger and has better plasticity, making it easier to form.

2. Rolling: The heated steel billet is pressed and stretched through a rolling mill or roller machine, and is gradually pressed into a steel plate or steel coil with the required thickness and width.

3. Cooling and finishing: The rolled steel plate or coil needs to be cooled and finished to improve the surface quality and make it meet the specifications.

Features and Benefits

1. High strength: Hot rolled coils have high strength and are suitable for a variety of structures and uses.

2. Good plasticity: The steel after hot rolling process has good plasticity, which is convenient for subsequent processing and shaping.

3. Excellent surface quality: The surface of hot-rolled steel coils is smooth and flat, without obvious defects such as oxide scale and uneven size. It has a beautiful appearance and is convenient for subsequent processing and surface treatment.

Hot-rolled steel coils are widely used in construction, manufacturing and other industrial fields due to their high strength, malleability and versatility. Its excellent properties make it one of the ideal materials in many engineering and manufacturing fields.
