Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] FIG. 1 shows a view of the two pieces that shall form the oven of the invention, recently unmolded and in the upper open position, so that the concavity thereof can be appreciated.

[0009] FIG. 2 shows a view similar to FIG. 1, wherein the upper part has been turned over prior to being placed on the lower part.

[0010] FIG. 3 shows a view of the finished oven, and a detail of the contact area between the two pieces, which are joined by refractory cement.

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

[0011] The oven (1) of the invention (see FIG. 3) is of the type that comprises a receptacle (2) of refractory material, wherein the receptacle (2) comprises two concave pieces (3, 4) that are joined by the edges (5) thereof.

[0012] Very preferably the edges (5) are joined with the participation of a refractory binder (6), since on the one hand it reinforces the joint, and on the other hand it cooperates in sealing the receptacle (2) against heat leaks. Said binder (6) ideally comprises refractory mortar.

[0013] In addition, it has been provided that the edges (5) are preferably coplanar in each piece (3, 4), that is, that all their points are contained in the same plane with the logical tolerances. In this case, entrance to the oven can be achieved by means of a recess (7) in the edge of the pieces (3, 4). It has also been provided that the edges (5) of both pieces may comprise mutually coupling tongue-and-groove joints (50), also to reinforce the settlement between both pieces (3, 4) and to prevent heat leaks.

[0014] Having sufficiently described the nature of the present invention, as well as a way of putting it into practice, it should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications in detail as long as they do not alter the fundamental principle
