Definitions

  • the invention relates to a galvanizing furnace and a method for operating a galvanizing furnace.
  • the galvanizing furnace generally includes a furnace housing having a galvanizing trough disposed therein.
  • the furnace housing typically has a rectangular cross-section.
  • the furnace housing has two opposite longitudinal side walls and two likewise opposite end side walls, wherein the longitudinal side walls are larger than the front side walls.
  • Burners in particular gas burners, are typically used to heat the liquid zinc in the galvanizing tank. These burners each heat the furnace interior between the walls of the furnace housing and the galvanizing trough by means of a flame tube. Furthermore, electrically heated galvanizing ovens are known.
  • a widely used burner system for such galvanizing furnaces operates with gas burners in the form of high speed burners. These high-speed burners are provided at diagonally opposite corners of the furnace housing.
  • the high-speed burners are each mounted in an end-side side wall of the furnace housing so that the flame generated by the respective high-speed burner in the gap between a longitudinal side wall of the furnace housing and a side wall of this opposite side wall of the galvanizing trough is.
  • several high-speed burners can be mounted one above the other in the diagonally opposite corners of the furnace housing.
  • the corner regions of the galvanizing trough which are directly opposite the flame outlets of the high-speed burners, are clad on their outer sides with flame deflectors and thus protected.
  • the invention has for its object to provide a galvanizing furnace and a method for its operation, which allows an increase in the availability of the galvanizing furnace with little design effort.
  • the invention relates to a galvanizing furnace having a galvanizing trough and a furnace housing enclosing the galvanizing trough, which has a rectangular cross section.
  • the furnace housing has two opposite longitudinal side walls and two opposite end side walls and further includes burners for heating liquid zinc in the galvanizing trough.
  • At least one first receptacle for a burner In the areas of the two other diagonally opposite corners of the oven housing a second receptacle for a burner is provided in each case.
  • the burners are arranged either in the first recordings or in the second recordings. Flames generated by the burners are each guided in the region between a longitudinal side wall of the furnace housing and the opposite wall of the galvanizing trough.
  • the invention relates to a method for operating a galvanizing furnace.
  • the availability of the galvanizing furnace according to the invention can be increased in a surprisingly simple manner.
  • the invention is based on the finding that the wear of the galvanizing trough is mainly due to the high temperatures generated by the burners. It was found that in the area of the flame outlet at the respective burner, or if the galvanizing a Flammenleitblech is located immediately behind the flame outlet, the strongest wear of the galvanizing occurs, ie in this area is reducing the wall thickness of the galvanizing due to high temperatures at the highest, whereas with increasing distance to the respective burner, the wear, that is, the reduction of the wall thickness of the galvanizing trough, continuously decreases.
  • the burners which are preferably designed as high-speed burners, can optionally be used either in the first recordings or in the second recordings.
  • the operation of the galvanizing furnace is then according to the invention such that the galvanizing is first operated for a predetermined period of time with the burners in the first shots.
  • the burner that is to say in the area of the first receptacles, experiences increased wear of the galvanizing trough, that is to say an increased reduction of the wall thickness. This wear decreases continuously along the respective side wall of the galvanizing trough in the direction of the second recordings.
  • the life of the galvanizing trough and thus the availability of the galvanizing furnace compared to a conventional operation of the galvanizing furnace are significantly increased.
  • the burners would always be stored only in the first recordings. This would selectively lead in the first recordings associated flame outlet areas to a spatially limited strong reduction of the wall thickness of the galvanizing, so that they must be replaced in a relatively short time.
  • the life of the galvanizing trough can be significantly increased, so that the intervals in which the galvanizing trough must be replaced by a new, can be significantly increased.
  • the time intervals in which the galvanizing furnace is operated with burners mounted in the first recordings or in the second recordings can be specified empirically.
  • means for location-dependent detection of the wear of the walls of the galvanizing trough are provided. Depending on the determined wear values, it is possible to change the burners from the first recordings to the second recordings or vice versa.
  • the time intervals in which the galvanizing furnace is operated with burners mounted in the first or in the second receptacles can be predetermined and optimized as a function of the measured wear values.
  • the wall thicknesses over the entire side walls of the galvanizing trough, along which the flames of the burners are guided, are measured.
  • the current wall thickness of the galvanizing trough is expediently detected in the region of the flame outlet of at least one burner. A change of the burners is then carried out when the current wall thickness falls below a predetermined limit.
  • an ultrasonic measuring head is provided for measuring the wall thickness of the galvanizing trough.
  • the ultrasonic measuring head it is possible to measure the wall thickness of the galvanizing trough during operation of the galvanizing furnace.
  • closable inspection openings are advantageously provided in the longitudinal side walls of the furnace housing.
  • the ultrasonic measuring head is guided through a control opening to the outside of a wall of the galvanizing trough.
  • the location-dependent course of reducing the wall thickness of the galvanizing trough can be accurately detected.
  • the measurements can easily be done by just one person.
  • the respective person only needs to open the closure of the desired inspection opening, in order then to guide the ultrasonic measuring head through the inspection opening into the furnace interior and then against the wall of the galvanizing trough.
  • the ultrasonic measuring head is designed as a so-called hot head, which is suitable for use at high temperatures, as in the interior of the furnace exist, is suitable. Furthermore, the ultrasonic measuring head advantageously has a magnet with which the ultrasonic measuring head can adhere to the wall of the galvanizing trough. This ensures an accurate and reproducible measurement of the wall thickness with the ultrasonic probe.
  • the receptacles for the burners are each arranged in a frontal side wall.
  • a plurality of receptacles, in each of which a burner can be arranged, are provided in each corner region of the furnace housing.

  • the galvanizing trough has a substantially rectangular shape adapted to the cross section of the furnace housing Cross-section on.
  • a Flammleitblech is attached to the outer wall of the galvanizing trough.
  • the burners can be stored either in the first or second receptacles and thus can be arranged in each corner region of the furnace housing, it is accordingly expedient to protect each corner area with flame deflectors against flames from burners.
  • control openings are provided in the longitudinal side walls of the furnace housing in such a way that the ultrasonic measuring head guided through such a control opening is guided directly against a wall of the galvanizing trough adjacent to a flame guide plate.
