大型支承辊低频感应淬火技术研究与应用
Research and application of low-frequency induction quenching technology for large backup rolls
摘要
Abstract
A large-scale backup roll induction quenching integrated equipment was developed with complete localization based on the"one-shot method"principle.The innovative application of high-power low-frequency(4MW/25Hz)digital power supply and multi-turn variable tap technology for induction coil.Combined with multi-furnace engineering temperature field tests,the induction heating simulation technology for large backup rolls was successfully developed,achieving full coverage of induction quenching technology applications for nearly 70 specifications of backup rolls[including(φ 1000～φ 1650mm)×(1200～2400mm)].A large number of industrial application practices have shown that the independently developed low-frequency static integral induction quenching integrated technology for large backup rolls can stably achieve the technical indicators of"roller body hardness uniformity △≤±1HS and'zero'hardness drop at 100mm in the radial direction of the working layer",with the hardness quality of the rolls reaching the international top level.关键词
