COLD ROLLED STEEL
290 次浏览
Cold-rolled steel refers to hot-rolled steel that has undergone further processing. Rolling involves the range of processes involved in forming the steel, including turning, grinding, and polishing. The other operations modify an existing hot rolled steel into a more refined product. The term “cold rolled” essentially applies to steels that have undergone compression.
At the cold reduction mills, the manufacturer cools the steel and re-rolls it at room temperature either by cold roll forming or press-braking. This process helps to achieve desired shape and dimensions.
Cold Rolled materials are HRP&O coils that have been cold-reduced and annealed. The thickness is more accurate than that of a HR. Also the surface is less porous and cleaner, as well as having better forming properties. The main uses are in auto parts, household appliances, lighting, furniture
