Cold plate specification
The difference between cold board and hot plate
Cold plate and cold rolling plate are based on hot rolling rolling rolls. At room temperature, rolled below the crystallization temperature, including boards and rolls. Many domestic steel plants such as Baosteel, Wugang, Anshan Iron and Steel can be produced.Among them, the delivery of Zhang Zhang is called a steel plate, also known as the box plate or tablet; the length is long, and the delivery of the roll is called a steel belt, also known as the coil plate.Hot plates, hot -rolled plates, hot tie plates are used as raw materials with linked plates or first rolling board blanks. After stepping in the heating furnace, heated, high -pressure water removes the scales and enters the rolled rolled machine.Then enter the refined rolling machine and implement the computer control rolling. After the final rolling, it passes through layer flow cooling (computer control the cooling rate) and the rolling machine roll to become straight hair rolls.
