Cold coil is made of hot rolled coil at room temperature and below the recrystallization temperature, including plate and coil, of which the sheet delivered is called steel plate, also known as box plate or plate; the long length and delivered in coil is called steel strip, also known as coil plate.
Production process:
Due to no heating, there are no pitting and scale defects in hot rolling. The surface quality is good and the surface finish is high. Moreover, the dimension precision of cold rolled products is high, and the properties and structure of products can meet some special requirements, such as electromagnetic properties, deep drawing properties, etc.
Performance: mainly made of low carbon steel, with good cold bending and welding performance, as well as certain stamping performance.
SPCC is commonly used cold rolled carbon steel sheet and steel strip.
SPCC Specification
Features of cold-rolled steel plate:
1, Cold rolled steel plate thickness more accurate, smooth surface, beautiful, but also has superior mechanical properties, especially machining performance.
2. The maximum thickness of cold-rolled steel plate is less than 0.1-- 8.0mm, such as the thickness of cold-rolled steel plate in most factories is less than 4.5mm;The minimum thickness and width are determined according to the equipment capacity and market demand of each plant.
3, cold rolled steel mill power, low rolling efficiency, and the rolling process in order to eliminate the work hardening have to carry out intermediate annealing, so the cost is higher, but cold rolled steel surface bright, good quality, can be used to process finished products, cold rolled steel is widely used.
