Abstract

1461976 Furnace linings; shields BRUUN & SORENSEN AB 8 April 1974 [9 April 1973] 15517/74 Heading F4B A framework for a refractory shield or furnace lining comprises a plurality of H- shaped elements, opposed sides of one leg of each H having concave surfaces, and the opposed sides of the other leg having convex surfaces. The elements are assembled on their sides, Figs. 1 and 2, the upper limb 11 of each element having convex surfaces 14 and the lower limb 12 of each element having concave surfaces 14, and a concave limb 12 and a convex limb 11 of each of two adjacent elements fit between the convex upper limb and the lower concave limb of each element. The thickness of each convex limb perpendicular to the plane of the H is less than the distance between opposing concave surfaces in the assembled framework, so that a damaged element may be removed with those below without disturbing elements above. The curved surfaces may be tapered so that a curved wall may be formed, Fig. 3. The top of the framework is provided with hanger elements, Fig. 5, the upper limb 7 of the element being longer than the lower limb 8 and having a channel section projection 4 to hook over a supporting beam. The upper limb 7 and lower limb have concave surfaces 6 to co-operate with the upper limbs of the main framework. The lower edge of the framework is finished by bottom members, Fig. 8, with channel shaped extensions to the lower limb, and a convex upper limit 21. The bottom members are of two types, the H-shaped type of Fig. 8 alternating with a T-shaped type, Fig 10, with the base of the stem having a channel section extension 18<SP>1</SP>. Shaped locking pieces engage the channels in the extensions 18, 18<SP>1</SP> to hold the framework in place. Each limb of each element has an undercut recess 25, Figs. 2, 5 and 10, and the cross-piece of each element is of cross shape in section, Fig. 3, so that refractory material applied to the framework is keyed in place.

Description

(54) FRAME The invention relates to scaffolds for protective devices, installed in furnaces, combustion chambers and the like. The known frame is predominantly for thermal units, which contains separate elements that form the main, upper and lower parts of the frame, which are installed with the possibility of F-X connector. A disadvantage of the known frame is the need to install the supporting ones. the surfaces or similar means on which the lining is installed forming the inner surface, which conditions the construction and installation of the device. The aim of the invention is to simplify the construction and installation of the frame. The goal is achieved by the fact that, in the frame, mainly for thermal units, which contain separate elements that form the main, upper and lower parts of the frame, which are detachably installed, the elements that form the main part of the frame are made with a transverse H-shaped section and protrusions. at the same time, in the same element, between the projections located one opposite the other, there are high1, which are bent outwardly, the surface of the other element, and protrusions, having surfaces bent inward, the third element. The thickness of the protrusions that have isoped inside the surface, each element i is not less than the thickness of the protrusions, and the surfaces bent outwardly. In order to prevent lateral displacement of the elements by means of fixing means, the elements installed in the lower and upper parts of the frame are provided with hook-shaped windows and transverse projections with surfaces bent inwards and outwards with recesses. To ensure | and the joints between the frameworks and the fire-resistant element, applied over the framework, to the front and rear side t of the protrusions of each element, make indentations extending inwards.

The frame for thermal units contains elements 1, forming the top. part of Kirkas, elements 2, forming the main part of the frame, and elements 3 (Fig. 7 and 8), forming the lower part of the frame. The elements 1 are provided with hook-shaped protrusions 4 (FIG. 5), intended for visiting and elements 1 on the part of the heat unit and formed by flange beams or similar means. Element 1 is made with inwardly curved surfaces 5 and 6 and is provided with transverse protrusions 7 and 8, the protrusion 8 being shorter than the protrusion 7. The protrusions 7 and 8 located one opposite the other surface 5 and 6 are bent inward, as a result of which recesses 9 and 10, directed in opposite directions.

Elements 2 forming the main

part of the frame, made with a transverse H-shaped section and protrusions 11 and 12 (Fig. 1) having the same lengths In each element 2, surfaces 13 and 14 of protrusion 11 are bent outward, and surfaces 1.5 and 16 of protrusion 12 are bent inward. In the gap 17 between the located one opposite the other, the protrusions 11 and 12 of one element 2 are located the protrusions 12 of another element 2 displaced laterally and vyspraspolozhennogo, and the protrusions 11 of the third element 2, shifted sideways and downstream, while the protrusion 12 vyraspolozhennogo element 2 matched with the surface

14 of the protrusion 11 of the first element 2 and with the surface 13 of the protrusion 11 of the third element 2, and the protrusion 11 of the third element 2 is associated with the surface 15 of the protrusion 12 of the first element.

The element 3, forming the lower part of the frame, provided with a hook-shaped protrusion 18 (Fig. 7 and 8) on the transverse protrusion

19 with an upper inward curved surface 20 and a transverse protrusion 21 with outwardly curved surfaces 22 and 23. In the embodiment of element 3, the hook - shaped protrusion 18 is made on the lower narrow web of element 3. The hook elements 18 form a nest for fixing means 24 ( Fig. 11 and 12), connecting the adjacent elements 2 and inserted from above into the slots of the hook protrusions.

On the front and rear surfaces of the elements 1, 2 and 3, recesses 25 are made in the form of a dovetail.

When assembling the frame of the heat unit, first elements 1 are hung on a part of the heat unit with hook protrusions 4, and then elements 1 sequentially visit elements 2 and 3. As a result of different heights of the elements 3 forming the lower part of the frame, a smooth bottom edge is obtained, which is fixed in the required position with the help of the locking means 24.

The thickness of the protrusions 11 and 21 of the elements 2 and 3, having 11x. The outwardly curved surfaces are equal to or less than the distance by the inwardly curved surfaces 5, 6, 15, 16, and 2O of the projections 7, 8, 12, and 19, as a result of which only a damaged element can be removed during carcass repair.

Elements 1, 2 and 3 can be brought into engagement and disengaged from adjacent elements 1, 2 and 3 by rotating around the protrusions 11 and 21 of elements 2 and 3 and removing from the corresponding gap between adjacent elements 1, 2 and 3 .

When a refractory material is applied to the frame of the thermal unit, the latter enters the recesses of 25 elements 1, 2 and 3, and the shape of the recesses prevents them from exiting the refractory material.

The frame can be made flat, cylindrical or arcuate. For the implementation of the lateral deviation between the elements 1, 2 and 3, the outward-facing surfaces 13, 14 of the centers 22, 23 of the projections 11 and 21 have a slight taper, i.e. the bending radius at the outer end of the surfaces 13, 14, 22, 23 is smaller than that at the inner end.
