Description

[0042] In the following, the invention is further described by the means of one embodiment. The figures showeach in a schematic representation:

[0043] FIGS. 1a-d: The structure of a brickwork assembly with bricks in three rows on top of each other,

[0044] FIG. 2: a schematic representation of the joint progression in the brickwork

[0045] FIGS. 3a-c: Cross sections A-A, B-B, C-C according to FIG. 2

[0046] FIG. 1 shows a lower, third row R3 of the brickwork assembly, consisting of three adjacent cuboidal refractory bricks R3.1, R3.2, R3.3. Two outer bricks R3.1, R3.3 are wider, thus have a wider front face VS than the brick R3.2 placed in-between. Joints between the bricks R3.1, R3.2 and R3.2, R3.3 are labelled F3.1, F3.2. The joints F3.1, F3.2 extend linearly and at right angles between the front faces VS and the rear faces HS of the bricks R3.1, R3.2, R3.3. Independently of the wear of the bricks R3.1, R3.2, R3.3 (in the direction of the joint), the position of the joints 3.1, 3.2 remains the same.

[0047] A second row of bricks R2 is arranged on top of the third row of bricks R3, consisting of two bricks R2.1, R2.2 which together (arranged adjacent to each other) form a cuboidal shape and have corresponding slanted side faces SF.

[0048] The right side face SF of the brick R2.1 in FIG. 1c extends at an angle of circa 45 to the front face VS, wherein a vertical joint F2 can be seen between the front faces VS of the bricks R2.1, R2.2 which extends offset (offset to the right) to the joint F3.2 when the brickwork is newly lined.

[0049] A first row of bricks R1 is arranged on top of the second row of bricks R2, consisting of two cuboidal refractory bricks R1.1, R1.2 which are of identical format and arranged in such away that the joint F1 which extends between the bricks R1.1, R1.2 extends exactly in the middle of the joints F3.1, F3.2 upon new lining.

[0050] In the plan (top) view this results in a joint progression as shown in FIG. 2. The FIGS. 3a-c show three degrees of wear according to FIG. 2.

[0051] It can be seen in FIG. 3a that the wear is at a stage where the joint F2 is aligned with the joint 3.2.

[0052] In FIG. 3b, the degree of wear of the bricks is at a stage that the joint F2 is aligned with joint F1, while in FIG. 3c the maximum degree of wear is shown where the joint F3 has moved so far to the left that it aligns with the joint F3.1 of the third row of bricks R3.

[0053] This corresponds to the wear up to the line C-C shown in FIG. 2. This is a signal to the personnel that the maximum degree of wear has been reached and the bricks have to be replaced.

[0054] All bricks within the displayed brickwork are MgOC bricks and the joints are filled with a refractory mortar.

[0055] In a reduced embodiment the brickwork only consists of the bricks of the rows R1, R2 and the degree of wear shown in FIG. 3b corresponds to the degree of wear at which the bricks have to be replaced.
