What are hot and cold plates?
Hot and cold plate is cold rolled sheet (coil) and hot rolled plate (coil) collectively.
Cold rolled coil is made of hot rolled coil as raw material and rolled under the recrystallization temperature at room temperature, including plate and coil. Many steel mills in China, such as Baosteel, WISCO, Anshan Iron and steel company, can be produced. Among them, the delivery is called steel plate, also known as "box plate" or "flat"; the length is very long, the volume of delivery, known as "steel band", also known as "coil.".
Production process: in the production process without heating, so there is no pitting and iron oxide defects often appear in the hot rolling, good surface quality, high degree of finish. Moreover, the cold-rolled products have high dimensional accuracy, and the performance and organization of the products can meet some special requirements, such as electromagnetic properties and deep drawing properties.
