Controlled Rolling Technology

Rolling control technology Rolling technology is a kind of metal cold processing technology which is widely used in modern metallurgical industry.It can make various kinds of ferrous metals and non-ferrous metals into cylindrical or tapered parts of different shapes and sizes through different kinds of rolling mills. It has the advantages of high production efficiency, saving energy, high accuracy of workpiece size, good surface quality and simple process, etc. In the production process of rolling technology, the quality of the workpiece size and the surface quality of the workpiece depend on the design and control of the rolling process. Rolling process control includes three main parts: the first is the time control, which is to control the time of rolling, which can make the workpiece reach the required size, strength, plasticity and other performance. The second is the rolling force control, which is to control the rolling pressure and make the workpiece reach the required size, strength, plasticity and other performance. The third is the temperature control of the rolling process, which is to control the rolling temperature and make the workpiece reach the required size, strength and plastic reliability. The rolling control technology used in the production process of rolling technology includes the time control of rolling, the force control of rolling and the temperature control of rolling. Through these three methods of rolling control, the quality of the workpiece size, the surface quality of the workpiece and the performance of the workpiece can be guaranteed. Time control of rolling. The main purpose of time control of rolling is to control the rolling speed in order to make the workpiece reach the specified size, strength and plasticity. The rolling speed should be selected according to the material and the rolling process. Generally speaking, the rolling speed should be fast when the material is hot and slow when the material is cold. If the rolling speed is too fast, the surface of the workpiece is easily damaged or the size of the workpiece is not accurate. On the contrary, if the rolling speed is too slow, it will affect the rolling efficiency and make the production stop. Therefore, the rolling speed should be controlled in order to make the workpiece reach the required size and performance. Force control of rolling. The main purpose of force control of rolling is to control the rolling pressure in order to make the workpiece reach the specified size, strength and plasticity. The rolling pressure should be selected according to the material, the rolling speed and the rolling process. Excessive rolling pressure often causes uneven thickness of the workpiece and adverse effects on surface quality and plastic reliability. Therefore, the rolling pressure should be controlled in order to make the workpiece reach the required size and performance. Temperature control of rolling. The main purpose of temperature control of rolling is to control the rolling temperature in order to make the workpiece reach the specified size, strength and plasticity. According to the size and properties of the workpieces, the rolling temperature should be reasonably selected. Generally speaking, the rolling temperature should be low for thick workpieces and high for thin workpieces. If the rolling temperature is too high, the workpieces plasticity and strength will decrease, and its size and surface quality will also be affected, while if the rolling temperature is too low, the workpieces plasticity and strength will increase, but its size and surface quality will still not meet the requirements. Therefore, the temperature of the rolling process should be reasonably controlled in order to make the workpiece reach the required size and performance. In summary, the quality of the workpiece size, the surface quality of the workpiece and the performance of the workpiece depend on the design and control of the rolling process. Rolling process control includes time control, force control and temperature control of rolling. By controlling the rolling speed, rolling pressure and rolling temperature, the rolling control technology can guarantee the quality of the workpiece size, the surface quality of the workpiece and the performance of the workpiece.
