Cold Rolled Steel Sheet High Productivity


The cold-rolled steel sheet is made of hot-rolled sheet at room temperature, although the steel sheet is heated during the machining process, although it is cold rolling. As a result of hot rolling through continuous cold deformation made of cold rolling, the mechanical properties are relatively poor, the hardness is too high. Cold-rolled Steel Plates Must be annealed to restore its mechanical properties, no annealing is called rolling hard roll. Rolling rolls are generally used for products that do not require bending or stretching.

Cold-rolled steel plate is usually seen in the box, from the steel when it has been a good start. Applicable to most of the manufacturing industry, the common specifications are: 0.7-3.0mm. Material ST12, ST13, ST14, ST15, ST16, ST17 and so on. Because from the steel out, Cold-rolled Steel Plates the mechanical group control is relatively fine, out of the cold-rolled steel plate is more accurate, so the general customer in the board is not required under the circumstances willing to use cold-rolled steel, that is, the so-called box. But there are also some manufacturers or manufacturers with board size requirements, such as a wider 1780 or narrower. Longer or shorter, this time, Cold-rolled Steel Plates you need cold rolled rolls. Cold rolled rolled as we saw in the daily life of the tape, the cold rolled steel rolled up, so called cold rolled coil. Cold rolled rolls can be sized according to customer requirements. It is more convenient to use.

Features of Cold Rolled Steel Plate

Production of steel methods are rolling, forging, extrusion, drawing and so on. Production of steel by rolling method, with high productivity, variety, the production process is strong, Cold-rolled Steel Plates easy to mechanize automation and so on. Therefore, 85 to 90% of the steel is produced in the rolling mill.

Cold rolling is a steel sheet that is further rolled to a desired thickness at room temperature. Compared with hot-rolled steel, cold-rolled steel plate thickness is more accurate, and the surface is smooth, beautiful, but poor mechanical properties, especially in processing performance. Cold-rolled Steel Plates Because the cold rolled original roll is more brittle, not suitable for processing, so under normal circumstances cold rolled steel plate after annealing and surface leveling before the customer.
