In the metal processing industry, the square tube mill is a key equipment for producing square steel tubes. The control of the roller spacing during the forming process is crucial. This link is not only directly related to the dimensional accuracy of the finished square tube, but also affects the production efficiency, material utilization rate and stable operation of the equipment.
The basic principle of used directly forming to square pipe mill of is to transform the metal billet from the initial form into a square steel tube of the required size through the gradual rolling of a series of rollers. In this process, the spacing of the rollers becomes a key factor in determining the dimensional accuracy of the finished product. If the roller spacing is too large, the size of the finished square tube will be too small, or even unable to form an effective square section; if the spacing is too small, excessive metal extrusion may occur, resulting in material waste and roller wear, and even damage to the equipment in severe cases.
In order to accurately control the roller spacing, the square tube mill is usually equipped with a precise roller adjustment device. These devices can automatically or manually adjust the relative position between the rollers according to the preset rolling parameters to ensure a constant spacing during the rolling process. The working principle of the adjustment device is based on advanced mechanical transmission and control systems, which can achieve micron-level control of the roller spacing and meet the needs of high-precision production.
In actual operation, precise control of the roller spacing needs to be started from multiple aspects. First, it is necessary to calculate a reasonable roller spacing based on the material, thickness and width of the metal billet and the size requirements of the finished square tube. This step usually relies on advanced computer-aided design (CAD) and computer-aided manufacturing (CAM) technology to ensure the accuracy and reliability of the calculation results.
Secondly, during the rolling process, it is necessary to monitor the changes in the roller spacing in real time. This is usually achieved through sensors and measuring instruments installed on the rolling mill, which can provide real-time feedback on the actual spacing of the rollers and compare it with the preset value. Once a deviation is found, the adjustment device will start immediately to fine-tune the roller spacing to ensure that it fluctuates within the allowable range.
In addition, attention should be paid to the wear of the rollers. As the number of rolling increases, the surface of the rollers will gradually wear, resulting in changes in the roller spacing. Therefore, the rollers need to be inspected and replaced regularly to ensure that they operate in the best condition. At the same time, it is also necessary to record and analyze the wear of the rollers in order to provide a basis for the subsequent adjustment of rolling parameters.
Used directly forming to square pipe mill of to square pipe mill is a complex and delicate process that requires advanced equipment and technical means to achieve. Through precise calculation, real-time monitoring and regular maintenance, it can ensure that the dimensional accuracy of the finished square pipe meets the requirements, improve production efficiency and material utilization, and create greater economic benefits for the enterprise.
