工频感应加热可用于轧辊和大型轴类零件的表面淬火,使用频率为50Hz 工业电源,不需要特殊供电设备。由于设备比较简单、生产率高、操作方便,易于实现机械化和自动化,能获得深的淬硬层,因此技术发展迅速,应用也越来越广泛。近年来,轧机向高速度、高载荷发展,大型冷轧工作辊的工频感应加热工艺,也在不断创新,以提高轧辊的质量。 Power frequency induction heating can be used for surface hardening of rolls and large shaft parts using a frequency of 50Hz industrial power supply, does not require special power supply equipment. As the equipment is relatively simple, high productivity, easy operation, easy mechanization and automation, can get deep hardened layer, so the technology is developing rapidly, the application is also more and more widely. In recent years, the mill to high-speed, high load development, large-scale cold-work roller frequency induction heating process, are also constantly innovating to improve the quality of the roll.
