After hot-rolled and cold-rolled c-beam photovoltaic support, stretch straightening is the first leveling method to be used. Tension straightening is the combination of stretching and bending technology, and the required operating power input is not high. It can effectively obtain excellent straightness correction ability. For the first type of defect, the straightness can be increased by 100 times. The technicians of Jinan c-beam factory believe that the tension produced by the roller tensioning device of the straightener on the steel strip is usually 15% - 25% of the yield stress and 0.002% of the elongation of the steel strip. Adjusting the elongation of the steel strip according to the size of the sickle bend can correct the flatness defect of the steel strip c-shaped steel photovoltaic support, and the operation is relatively simple.
After leaving the hot rolling mill, carbon steel and stainless steel coils are usually pickled before further cold rolling. The connecting straightening machine is used in most modern pickling lines to improve the flatness of the c-shaped steel photovoltaic support, reduce warpage and help to break scales. Placing the straightening machine at the inlet of the pickling line can remove some iron scales and improve the pickling efficiency.
In the process of acid washing, the improvement of the straightness of the c-shaped steel photovoltaic support can better pass through the plate and reduce the noise of the strip steel. Reducing warpage can make the strip steel pass through the pickling line quickly without passing through the plate. When using a high-quality welding machine to weld the strip, the head and tail of the steel strip with poor shape can be straightened to reach the same quality as the main body of the steel coil. The iron scale powder can fall into the wet sludge or absorb and remove the floating dust through the duct dust suction system.
In the hot and cold rolling process of the c-beam photovoltaic support. Efforts to improve the shape of the plate are being carried out extensively. The main purpose of rolling is to make the c-beam photovoltaic support reach the predetermined thickness and shape. At the same time, the straightness of the c-type steel photovoltaic support shall be guaranteed.
During the leveling process after rolling, the c-section steel photovoltaic support shall meet the flatness requirements at the end of use, and the performance and coating quality of the c-section steel photovoltaic support shall be improved. Improve the output and productivity of the leveling process. In order to improve the straightness of the c-beam photovoltaic support, different forms of leveling technology are applied, which can make the c-beam photovoltaic support obtain a specific shape for further rolling.
After the steel strip is rolled. Before the final delivery, there are many uncoiling, rewinding and heat treatment processes. In these processes, stretch straightening and roll leveling are used many times to change the shape of the c-beam photovoltaic support.
