Coating furnace

BACKGROUND OF THE INVENTION The present invention relates to a metallization furnace, in particular a zinc plating with a ceramic and a bath tub.

In aaa-temporal dubbing, there is a fixed ceiling of the tapping part and a dividing partition between the topnau part and the working part at the baking ovens. This gives the size of the working position regardless of the product range, and the size of the product varies over time. During working breaks, heat is sucked into the ancient hall and aunt's heat needs to be replenished, which means increased energy consumption, mainly gas. Only some furnaces are covered with a self-insulating cover, which must be stored close to the furnace and placed above the bath and removed before starting work. If the plating pause is shorter, the bath remains exposed.

These drawbacks have been eliminated by the metallization furnace of the present invention, characterized in that the furnace ceiling lining is rigidly connected to the furnace ceiling support structure, which is movable in both vertical and horizontal directions.

The bearing structure of the ceiling of the furnace is connected via a lifting device to a running gear which corresponds to a rail which is mounted on the substructure.

A separating wall, including a cutting edge, is attached to the structure of the furnace ceiling, to which a vapor extraction outlet above the bath is associated on the side of the working portion of the furnace.

The movable ceiling allows the size and assortment of the goods to be packed immediately to be adjusted even at very short breaks. This property of the furnace allows substantially

213 O 4S reduce the consumption of heat escaping today by radiation from the working part of the pool.

In the case of high consumption of heat by metal plating, it is possible to quickly heat up the pool area by heating up the entire pool area and thus increase the productivity of work.

An exemplary embodiment of a baking furnace according to the invention is shown in the drawings, wherein FIG.

Fig. 2 shows a longitudinal section of the furnace in the left half along section line C-C and in the right half along section line D-D in Fig. 1.

In an exemplary embodiment of the galvanizing furnace according to the invention, it is based on a substructure

1, to which the movable ceiling support structure 2, which is provided with a lining 11, is associated. The entire ceiling including the support structure 8 and the lining 11 is supported via a lifting device 11 ensuring vertical movement of the ceiling and a running device providing horizontal movement on the substructure 1 The horizontal movement of the ceiling is ensured by the drive 4, which consists of an electric motor and a gearbox with the possibility of manual movement. Vertical movement is provided by hydraulic cylinders. The two movements of the furnace ceiling are interconnected in such a way that a horizintal movement cannot be performed without first raising the ceiling.

In the ceiling of the furnace are built-in burners 10, divided into groups with automatic shutdown when leaving the furnace space.

A separating wall 8 is attached to the furnace ceiling structure 2, separating the working and melting furnace sections, which is provided with a separating lip 7. On the side of the furnace working space, a separating wall 12 is assigned to the separating wall 8 for exhausting vapors above the bath. Observation and measurement holes are provided in the side walls and in the ceiling of the furnace.

Claims (3)

SUBJECT OF THE INVENTION Plating furnace, in particular for galvanizing, characterized in that the furnace ceiling lining (11) is rigidly connected to the furnace ceiling support structure (2), which is movable in both vertical and horizontal directions. The metallization furnace according to claim 1, characterized in that the support structure (2) of the furnace ceiling is connected via a lifting device (5) to a carriage (6) corresponding to a rail (3) which is supported on the substructure (2). 1). The metallization furnace according to claim 1, characterized in that a separating wall (8) including a separating blade (7) is attached to the furnace ceiling structure (2), to which a vapor extraction hood (12) is associated on the side of the furnace. above the bath. 2 drawings 213 04S The invention relates to a metallization furnace, in particular a zinc-coated furnace with a movable ceiling, in both vertical and horizontal directions for furnaces having a ceramic & metal tray. The essence of the invention is that the lining of the furnace stroxp is rigidly connected to the supporting structure of the furnace ceiling, which is mounted movably in both vertical and horizontal directions. The bearing structure of the furnace ceiling is connected via a lifting device to a running gear which corresponds to a rail which is supported on the furnace bottom structure. A separating wall, including a cutting edge, is attached to the structure of the furnace ceiling, to which a vapor extraction system above the bath is assigned from the side of the working part of the furnace. The subject matter of the present invention is best seen in the appended Fig. 1. The present invention can be used to reduce heat leakage from the working area of a pool in all of the plating furnace designs.
