Main equipment installed in steel works of JFE Steel have passed 30–40 years since its operation. Inspection activities of cracks and corrosion have been strengthen to prevent equipment failure due to aging. In addition, high operating rate and stable operation have been required to improve equipment efficiency. The development and introduction of higher efficient equipment monitoring technology is needed and JFE Steel has developed technologies such as remote control diagnosis device to measure cracks and steel thickness without building a foothold, new diagnosis system for low speed rotating machines and journal bearings, diagnosis technology for large-sized motors and generators without stopping the motor. These new monitoring technologies have contributed to production improvement and establishment of “Safe Safety” operations.
