- Bricks lined vessel known, with some stones are shaped and arranged to each other, that the wear of the stones can be detected from the front.
- two stones are used, which in each case have an obliquely running side surface between parallel front and rear end faces.
- the two stones are laid form-fittingly along their sloping side surfaces. The respective degree of wear results accordingly by a displacement of the joint along the inclined surface
- the invention is based on the object to provide a wear detection for refractory bricks, with the
- Wear rate can also be determined quantitatively.
- the corresponding stones in the known solution are offset by 90 ° from the rest of the lining.
- the stones are arranged with oblique side surfaces between two continuous stones of large size.
- the "wandering of the joint" (the lateral displacement of the joint) with increasing degree of wear depends on the angle between the face and the side surface of the stones.This angle is generally unknown, and the degree of displacement can thus never be determined quantitatively.
- the invention provides, this gap between the
- Inclined surfaces of adjacent stones offset to arrange at least one joint of a row of stones arranged above or below, this adjacent row of stones consists of stones whose format is such that the gap formed between the stones remains essentially the same place de (viewed from the front) , independent of
- different degrees of wear can be indicated, for example 1 ⁇ 4, 1 ⁇ 2 or% of the maximum degree of wear or 1 ⁇ 3, 2 ⁇ 3 or 1/5, 2/5, 3/5, 4/5, 5/5.
- Stone composite can be visually easily evaluated. Special measuring devices are not necessary.
- the wear indicator is reliable. It can be placed in one or more places within the refractory lining. The Verschl casanzei ge exists
- the invention relates in its most general embodiment, a refractory ceramic stone composite with the following features: a first row of at least two juxtaposed refractory Kerami's stones, between which runs a joint that retains its position and orientation in the stone composite, regardless of degree of wear of the stones ei ner second row of at least two refractory ceramic bricks, which are separated from each other by a joint form-fitting side and adjacent to the joint side surfaces of the stones with corresponding front faces of the stones an angle ⁇ between 10 ° and 80 ° or between 1 70 ° and 1 Make 00 °,
- the joint of the first row runs in the same orientation, but offset to the joint of the second row.
- alignment of the joint refers to the orientation of the joint, that is, in particular vertically in the stone composite
- the viewing of the joint (s) is always from the front, ie from an oven interior to the
- An advantageous wear indicator results when the joint of the first row is at a distance from the joint of the second row corresponding to a displacement of the joint of the second row, when the stones of the second row are worn so far that they are to be replaced and the Fugue of the second row is aligned with the fugue of the first row.
- the stone composite consisting of at least two rows each
- Other stones in a row can be identical to the other stones in the series or have a different shape.
- the stones can be glued or mortared together.
- the joint width can be adjusted for each application.
- all joints between the front end face and the rear end face of the stones should be as constant as possible
- the corresponding, sloping side surfaces of the stones of the second. Row can be between the front and back
- the angle to the sloping side surfaces of the stones is clearly defined.
- the angle is determined by an imaginary surface, which is spanned between the left and right edge of the front face of the stones.
- the angle between the front end faces of the stones of the second row and the adjacent side faces is e i ner
- Embodiment more than s 30 ° for the one stone or less than 1 50 ° for the corresponding stone.
- the values are ⁇ 60 ° and> 120 °, whereby the values are advantageously 1 80 ° +/- max. Add 1 0 °.
- the concrete rules can be selected specifically for each application, and in such a way that they can be used to identify a particular candidate
- the stones of the first row may consist of two stones of the same format, for example two parallelepipedic stones,
- a third row of stones can be added, arranged so that the second row is between the first and third row.
- the third row then consists, for example, of at least three refractory ceramic bricks, with a joint extending in each case between adjacent bricks, which retains its position and alignment regardless of the degree of wear of the bricks
- the joints of the third row are aligned in the same orientation but offset to the joints of the first row and the second row.
- the joints of the third row are preferably also offset to the joints or within the first row.
- the stones of the third row can have different formats, for example, a narrow stone (a stone with a narrower
- the stones of the third row may also have a cuboid shape
- stones can be used which have a trapezoidal shape, for example, in the top view.
- Other stone form ate are possible without departing from the spirit of the invention.
- the arrangement of the stones in the Neuzusteliung the stone composite is, for example, chosen so that the joint of the second row is flush with a joint of the first row or the third row, when the stone composite has reached 1 ⁇ 4, 1 ⁇ 2 or 3 ⁇ 4 of the degree of wear, in which replaced the stones should be.
- the gradation is, for example, chosen so that the joint of the second row is flush with a joint of the first row or the third row, when the stone composite has reached 1 ⁇ 4, 1 ⁇ 2 or 3 ⁇ 4 of the degree of wear, in which replaced the stones should be.
