1. Definition:

An HR Plate is a flat steel product that is made by heating and rolling steel at high temperatures (usually above 1,000°C). The hot rolling process ensures that the material is easy to shape and form into large sizes, making it suitable for a variety of applications where strength and durability are required.

2. Production Process of HR Plates:

• Heating: Steel slabs are heated to very high temperatures in a reheating furnace.

• Rolling: The heated steel is passed through a series of rollers to reduce its thickness and achieve the desired dimensions. This process also improves the mechanical properties of the steel.

• Cooling: After rolling, the hot steel plate is cooled naturally, which may result in a rough surface texture.

• Cutting and Inspection: The finished HR plates are cut to size and inspected for quality, ensuring they meet the required specifications.
