Description

JÜDk

The annealing material is transported in the annealing furnace by rollers made of highly heat-resistant materials. When passing objects of great length and small cross-section, such as in particular pipes and Small diameter rods present difficulties in that these articles sag and get caught under the transport rollers. So far, to remedy this problem, For the purpose of transporting the annealing material, glow shoes are used in which the otherwise sagging material is inserted became.

The subject of the invention is a device in annealing furnaces when the annealing material is transported on rollers, especially for the passage of pipes, rods and other objects of great length and small cross-section, characterized by being arranged between the rollers and free of thermal stress in the conveying level mounted baffles.

Further details and a preferred embodiment of the invention emerge from the following Description on the basis of the drawing.

Fig. 1 is a plan view of the device according to the invention;

Fig. 2 is a side view of the section along the line H-II of Fig. 1;

Figure 3 is a perspective view of the baffle support.

Guide plates 2 are arranged between two transport rollers 1, expediently at an angle of inclination from about 5 ° to the horizontal. In order to achieve a thermally optimal circulation of the The heat transfer medium, generally air, is the distance between the baffles and those leaving the material to be annealed Rolls appropriate 5 to 10 cm. On the next roller that takes up the material to be annealed in the direction of movement If the baffles lie loosely, it is advisable to do so a few millimeters below the apex of the roll. The baffles are laterally at least close to the rollers that take up the material to be annealed in the direction of movement upwards, 3, angled so that the material to be annealed cannot come off the track.

With regard to the temperature fluctuations inside the furnace, the guide plates are in the conveying level stored without thermal stress. This is achieved by being rigid with the underside of the guide plates connected, e.g. B. welded, suitably oval socket pipes 4 support elements with play loosely out are rigidly connected to bearing elements arranged perpendicular thereto, which are movable in trough-shaped Recesses are stored. As support elements and bearing elements are preferred Tubes 5 and 6 are used that are detachable or non-detachable, e.g. B. by welding, rigidly connected to each other are. The tubes 6 are, for example, in a facility in annealing furnaces

Trough-shaped recess stored in the furnace floor itself.

The tubes 6 serving as bearing elements expediently have such a longitudinal dimensioning, that a plurality of tubes 5 serving as support elements can be attached to a tube 6.

An arrangement of baffles in annealing furnaces is already known; but it served completely others Purposes that are not related to the transport of the material to be annealed through the furnace, but rather through the For example, a controlled distribution of heat within the furnace should be sought.

A roller cooling furnace for intermittently rolled glass plates is also known, in which the plates produced in a rolling machine are fed to the cooling furnace either directly or on a roller conveyor over inclined surfaces. However, there are other considerations for the downward routing of just cast or rolled glass plates obliquely downward than for the forwarding of heat material in a horizontal plane according to the invention. An indication of this is not given by the known arrangement of the inclined surfaces insofar as in the known cooling furnace itself with its horizontal conveyor roller route arrangements corresponding to the inclined surfaces are not made, although a ¹ larger roller spacing could also come into consideration there glass plates that have not yet become sufficiently stiff could result in uselessness.
