Definitions

  • the galvanizing furnace generally comprises a furnace housing with a galvanizing trough arranged therein.
  • the furnace housing typically has a rectangular cross-section.
  • the furnace housing has two opposite longitudinal side walls and two opposite front side walls, the longitudinal side walls being larger than the front side walls.
  • Burners in particular gas burners, are typically used to heat the liquid zinc in the galvanizing tub. These burners heat the interior of the furnace between the walls of the furnace housing and the galvanizing tank through a flame tube. Electrically heated galvanizing furnaces are also known.
  • the corner areas of the galvanizing tub which are directly opposite the flame outlets of the high-speed burners, are covered on their outside with flame guide plates and thus protected.
  • the availability of the galvanizing furnace according to the invention can be increased in a surprisingly simple manner.
  • the service life of the galvanizing tub can be increased significantly, so that the intervals in which the galvanizing tub has to be replaced by a new one can be considerably increased.
  • the time intervals in which the galvanizing furnace is operated with the burners stored in the first receptacles or in the second receptacles can be predetermined empirically.
  • the wall thickness of the galvanizing tub can be measured with the ultrasonic measuring head while the galvanizing furnace is in operation.
  • the galvanizing tub has an essentially rectangular shape that is adapted to the cross section of the furnace housing Cross section on.
  • a flame guide plate is attached to the outer wall of the galvanizing tub.
  • the outputs of the burners are expediently set as a function of the measured values recorded with the first or second temperature sensors.
  • the upper edge of the galvanizing tub 6 is received in an edge segment 9 of the furnace housing 2 running on the upper sides of the longitudinal side walls 4 and the end side walls 5.
  • the open top of the galvanizing tub 6 can be closed with a cover, not shown.
  • the interior of the furnace housing 2 is heated by means of burners.
  • the burners are designed as gas burners, in the present case as high-speed burners 14.
  • control openings 19 are incorporated into the longitudinal side walls 4 of the furnace housing 2, which can be closed with covers not shown separately.
  • ultrasonic measuring heads (not shown) are provided. To carry out such a measurement, the cover is removed from a control opening 19 and then the ultrasound measuring head is guided through the control opening 19 to the wall of the galvanizing tub 6, where the ultrasound measuring head adheres to the wall of the galvanizing tub 6 in a defined measuring position, preferably by means of an integrated magnet.
  • the galvanizing furnace 1 can continue to be operated without the risk of damage, since in the second phase, with high-speed burners 14 in the second receptacles 16 in areas A, only there is little wear.
