Definitions
- the present invention relates to a repair process and / or partial construction at hot industrial facilities including a structure in refractory materials, in particular installations operating by indirect heating using flues, such as coke oven batteries, according to which at least one element is used prefabricated in refractory materials which are secured with said structure by reactive projection, by means a carrier gas stream containing oxygen, a mixture of particles which can react exothermically with oxygen and particles of refractory material, preferably inert.
- French patent FR 2541440-B1 (Glaverbel) describes a hot repair process using, on the one hand, such bricks of vitreous silica and, on the other hand, a ceramic welding process for make the joints of the new masonry and the full reloading of the structure (GB 1.330.894 and GB 2.110.200 A from Glaverbel).
- the bricks of glassy silica preferably have a chamfer for facilitate the creation of joints.
- the glassy silica bricks when brought to high temperature, start a slow process of crystallization (in cristobalite and tridymite), they do not keep their sensitivity to creep when they are subjected to a load at high temperature.
- One of the essential purposes of this invention aims to propose a new method to remedy to the aforementioned drawbacks calling into question the reliability of this type of repair or partial construction and this in a relatively simple and economical way justified.
- the invention provides a method of hot repair of industrial installations comprising a structure of refractory materials (11) of a siliceous nature, in particular installations operating by indirect heating using flues (10), such as batteries of coke ovens, according to which use is made of at least one prefabricated element (1) made of refractory materials which is secured to said structure (11) by projection, by means of a stream of carrier gas containing oxygen, a mixture of refractory particles and particles which can react exothermically with oxygen chosen from the group formed on the one hand, by the following metals: Al, Si, Mg, Ca, Fe, Cr, Zr , Sr, Ba and Ti, and, on the other hand, by the compounds of these metals which can, by decomposition, form with oxides derived from these metals, mixed oxides, so as to constitute a binding phase for the abovementioned particles in refractive material shut up, these particles of a refractory material making it possible to form in situ a coherent refractory mass (14) fixing the
- This prefabricated element is characterized by the fact that it is based on a refractory product to Mullitic crystallization with alumina content between 30 and 85% and preferably between 50 and 80% alumina and which preferably has a prismatic shape rectangular, one of the faces of which is provided with means for perform mechanical attachment with a refractory mass coherent formed by reactive projection on this face.
- Figure 1 is a sectional view along line I-I of FIG. 2, of a prefabricated element suitable for implementing the method according to a preferred embodiment of the invention.
- Figure 2 is a front view of the prefabricated element.
- Figure 3 shows a section vertical portion of coke oven wall repaired by the implementation of the method according to the invention.
- Figure 4 is a horizontal section partial reconstruction of part of flues according to the method of the invention.
- Figure 5 shows a graph showing the expansion curve in% as a function of the temperature of different refractory products.
- the present invention therefore also relates to well hot repair of industrial plants comprising a structure of refractory materials that the hot reconstruction of part of such installations industrial and hot modifications to them.
- the process, following the invention is based on the dissociation of stresses encountered at the exchange wall of heat from a structure of refractory materials industrial installation.
- the invention is therefore applicable in all industrial facilities where such situation occurs.
- composition of this mixture is chosen in such a way as to form a mass in situ refractory that is compatible with the composition and coefficient of thermal expansion, on the one hand, of the element and, on the other hand, the original masonry, and this taking into account the stresses to which this mass will be subject to working conditions.
- this element prefabricated has the advantage of having good strength thermal shock, while ensuring refractoriness, high mechanical strength and creep resistance in a wide range of temperatures.
- the refractory mass thus deposited by reactive projection on the prefabricated elements can have a nature chemical different from that of these elements, this mass refractory constitutes with these elements a very good interface.
- the granular fraction of inert refractory particles based on oxides such as: SiO 2 , Al 2 O 3 , ZrO 2 , MgO, Cr 2 O 3 , TiO 2 , CaO
- oxides such as: SiO 2 , Al 2 O 3 , ZrO 2 , MgO, Cr 2 O 3 , TiO 2 , CaO
- the pulverulent fraction composed of oxidizable particles of metallic nature such as: Al, Si, Mg, Fe, Cr, Zr, Ti
- chemical substances which, by decomposition, form, with the oxides derived from the oxidizable particles, mixed oxides so as to constitute a binding phase for inert refractory particles.
- chemical substance should be understood to mean in particular metallic peroxides, such as CaO 2 , MgO 2 , BaO 2 , SrO 2 or metallic salts such as AlCl 3 , SiCl 4 , MgCl 2 .
- refractory particles based on the oxides mentioned it is necessary to understand their different mineralogical varieties such as tridymite, cristobalite and silica glass for SiO 2 as well as associated forms like zircon ZrSiO 4 , spinel MgAl 2 O 4 , zirconia stabilized with CaO or MgO, the solid solution Al 2 O 3 -Cr 2 O 3 in any proportion, etc., which each have a particular technological interest depending on the application envisaged.
- the attachment between the coherent mass projected refractory and the prefabricated elements is further favored by providing, on the latter, on the side of the heat treatment chamber, means for producing mechanical attachment between it and the mass projected refractory.
- the prefabricated element suitable for carrying out the following process the invention is formed from a prismatic block rectangular 1, the side 2 of which is intended to be directed to the heat treatment chamber is provided with means for producing, in addition to the ceramic bond obtained by reactive projection, mechanical locking with the refractory mass applied to this face 2.
- these means are formed by a mortise-shaped notch 3 extending parallel to the longitudinal edges of this block over the entire the length of the latter and substantially in the middle of its side 2.
- this block advantageously has at its upper 4, lower 5 and lateral 6 and 7 faces, corresponding fitting means, so that allow precise and stable dry stacking of several blocks 1 on top of each other.
- these interlocking means are: on the faces lower 5 and lateral 7, a groove 8 extending also over the entire length of these faces and, at the faces upper 4 and side 6 opposite, a rib corresponding 9 can engage in a groove 8 of a stacked block.
- This example concerns the repair of a partition wall between flues and a room thermal coke ovens as shown schematically to Figure 4 attached.
- the damaged area of the wall to be repaired was first cleaned to clear the parts healthy of its structure.
- the wall to be repaired had a 11 cm total thickness, while the thickness of the blocks 1 was 5 cm.
- the junction between the new masonry, formed by these blocks 1, and the old masonry 11 of the wall as well as the covering of the face 2 of the blocks directed towards the heat treatment chamber 12 were produced by reactive spraying in an oxygen stream containing 13% by weight of Si with an average diameter of 20 ⁇ m, 12% by weight of CaO 2 with an average diameter of 10 ⁇ m and 75% of SiO 2 , in the form of tridymite and cristobalite with an average diameter of 300 ⁇ m.
- the repaired area which restored the profile and the thickness of the old masonry 11, was therefore consisting of masonry 13 of mullitic nature on the side flue 10 and a siliceous refractory layer 14 formed by reactive projection, firmly linked to blocks 1 by ceramic bond and mechanical anchoring in notches 3 on the side of the heat treatment chamber.
- Figure 4 which is a section partial horizontal, shows a variant of this example 1 and concerns the partial reconstruction of a flue 10.
- This example mainly concerns the repair of large areas of an exchange wall of heat between flues and a treatment chamber thermal. It can therefore be the illustrated case as well by FIG. 3 than that illustrated by FIG. 4.
- repair block 1 for example for a coke oven, must both resist thermal shock during installation and move closer to the expansion plan, masonry behavior original 11 in silica bricks and that of the layer refractory 14 formed by reactive projection, it has been found, in a rather unforeseen way, as already indicated above, that a block 1 of mullitic nature represents a interesting compromise to satisfy these two requirements antagonistic.
- a variant of the invention consists in using a mixture of repair to be projected, in which one has replaced, within of the refractory charge, part of the silica crystallized (cristobalite and tridymite) by a fraction of vitreous silica, the particle size of which is included between 100 and 500 ⁇ m and preferably between 200 and 400 ⁇ m.
- the graph shown in Figure 5 gives different expansion curves of the products involved in repair and hot reconstruction industrial facilities.
- curve A relates to the expansion in% as a function of the temperature of a crystallized silica brick
- curve B relates to the refractory mass 14 obtained by reactive spraying of a mixture corresponding to the formulation given in Example 1
- curve C is that of the mullitic block 1
- curve D is that of a glassy silica brick
- curve B ' is that of a refractory mass obtained by reactive projection of a mixture corresponding to the following formulation :
- the benefit of this addition is to reduce the mechanical stresses, to the working temperature, which may result from a disagreement thermal over a long interface, without this addition has a negative influence on mechanical properties of the repaired area.
- the invention is not not limited to particular embodiments of concrete examples but that other variants may be envisaged in the context of the invention, both in this which concerns the shape and dimensions of the blocks mullitics and the means to achieve mechanical anchoring possible refractory mass projected 14 on side 2 of these blocks.
- the mortise-shaped notch 3 does not for example not necessarily extend to the edges longitudinal of side 2 but could for example extend obliquely or perpendicularly to these edges. So instead of forming continuous grooves across the entire length of the repaired area, the 3 notches in the assembled blocks could form interrupted grooves.
- the relative report of the quantities used for each of the components of this mixture may vary within limits relatively wide as long as care is taken to avoid this projected refractory mass can by reaction chemical degrade blocks 1 and that total expansion of this mass and blocks at working temperature does could cause the refractory mass to drop out blocks 1.
- the allowable difference between these expansions largely depends on the surface to be repaired. So, for relatively small areas a larger gap it is accepted that when the surface to be repaired is relatively large where it is necessary to ensure that the dilations are as close as possible to each other.
- the prefabricated element 1 may have a hole, of preferably of rectangular section, facilitating the manipulation of the element during its installation.
