An equipment management system is provided with an RFID provided for each equipment, an equipment position information storage unit, an equipment management data storage unit, an image information storage unit, a reader/writer, and a portable information terminal transmitting and receiving information with each storage unit. The image information storage unit has point group information and other image information of the inside of a facility. The equipment position information storage unit has installation position information of the equipment associated with the RFID and a virtual tag allowing reference to equipment management data on the equipment management data storage unit corresponding to the equipment and the image information associated with the equipment associated with the RFID in the image information storage unit. The portable information terminal has a confirmation information acquisition unit capable of acquiring information of the virtual tag corresponding to the RFID based on information from acquired RFID.

Equipment management system

Provided is a vertical annealing furnace, in which a heating zone and a soaking zone are communicated with each other in the upper part of the furnace, in which a part of the furnace other than the communicated parts is separated by a dividing wall, in which part of the furnace gas is suctioned into a refiner having a deoxidation device and a dehumidification device which is placed outside the furnace to decrease the dew point of the gas by removing oxygen and moisture from the gas and such that the resultant gas having a decreased dew point is returned into the furnace, in which a gas suction port into the refiner is located in the lower part of the connection part between the soaking zone and the cooling zone and in which one or more gas suction ports are located in the parts of the heating zone and/or the soaking zone outside of an area within 6 m in the vertical direction and 3 m in the longitudinal direction of the furnace from the steel strip entrance in the lower part of the heating zone.

Continuous annealing furnace for steel strip, continuous annealing method, continuous galvanizing apparatus and method for manufacturing galvanized steel strip (as amended)
