Abstract

The invention relates to the building construction of blast furnaces and can be used in the reconstruction and overhaul of blast furnaces. The purpose of the invention is to improve the convenience of the production of works in the reconstruction and overhaul and reduction of metal consumption. The support system of the blast furnace 8 contains the posts 1 and the beams 2 connected to them. New in the system is that the system is made of two inclined beams 2 and two racks 1, the latter are located outside the working area on one side of the furnace 8, while the beams 2 are positioned above the top of the top plate 9, supported on top of the stands 1 and connected to the stands which are fixedly fixed between themselves in the transverse direction, and the beams are connected to the inclined skip bridge 10 by the communication system 3. 1 c.p. f-ly, 7 ill.

Description

The invention relates to the building construction of blast furnaces and can be used in the reconstruction and overhaul of blast furnaces.

The purpose of the invention is to improve the convenience of the production of works during reconstruction and overhaul and reduction of metal consumption "

Fig „1 shows the support structure of the blast furnace, general side view; in fig. 2 is a section A-A in FIG. 0 1; FIG. 3 shows a section BB in FIG. 1; in fig. 4 - section bb In Fig 1; FIG. 5 is a section on the HGD of FIG. one; in fig. 6 is a general side view of the support system of the blast furnace when the side of the furnace is fed (sliding) a new furnace without its dome; in figs 7 - the same, when feeding from the side (sliding) new

one-piece furnace casing with a top plate mounted on it.

The support system contains two racks 1, two inclined beams 2, connection 3 beams 2, connection 4 racks 1, suspension 5, temporary struts 6, auxiliary beams 7 with

Racks 1 are located on one side of the blast furnace 8 at a distance, at which they do not interfere with the work during reconstruction and overhaul of the blast furnace. Racks 1 in the transverse direction are bonded to each other by ties 4 g. Beams 2 are located console above the top plate 9, supported on top of racks 1 and fixed with an inclined skip bridge 10 by the communication system 3, which ensures the geometric invariance and stability of the beams 2.

The beams 2 can be solid and lattice and are made obliquely, for example, parallel to the span of the inclined bridge 10. Each beam 2 is fixed with the lower end to a fixed support located in the skip area, the second mobile support is stand 1, which is the mobile support of beam 2 in the longitudinal

the direction in the transverse direction of the support 1, due to the connections between them m 4, are non-fixed supports for the beams 2. Racks 1 are located outside the working area in alignment with the pylon 11 of the inclined bridge 10 "

Racks 1 with links 4 and beams 2 with links 3 are designed for loads arising from the suspension to the cantilever sections of beams 2 of the blast furnace top furnace device, tsa. top site 9 with a pile, vertical ducts 12 and the upper part of the furnace casing, for example, the dome part 13. When combining the design of the supporting system with the design of the inclined bridge, the loads from the skip farm are added to the specified loads.

This design of the support system can be used both during the reconstruction and overhaul of the blast furnace, and during its operation. In the case when the support system is used during the operation of the furnace, the top plate 9 with a pile and equipment on it is fixed to the beams 2 with the help of hangers 5 (the copra design can be eliminated and replaced by the corresponding structures attached to the beams 2). system, which, in particular, eliminates the need to use the support site with a pile of columns of the furnace shaft for supporting).

The use of the support system during the stopping of the furnace for reconstruction or overhaul makes it possible not only to enlarge as much as possible and freely supply the new components and elements of the furnace to the side of the installation site, but also to replace the furnace casing fully together with the structures adjacent to it. I

using the hangers 5, the top plate 9 with the equipment supported on it and vertical guokhohod 12 together with the dome 13 attached to them 13 of the furnace 8 is fixed to the beams 2. The new furnace 8 assembled aside (without the dome part) is fed to the entire installation site from the side by sliding .

FIG. 7 shows the support system with the complete replacement of the furnace casing together with the top plate. In this case, the support system takes up the load from the remaining vertical ducts 12, which in the lower part loosen for the time of installation with temporary struts 6, is supported on the beams 2 by means of auxiliary beams 7. The new furnace casing 8 is assembled aside A new top plate 9 is mounted, after which the entire structure is fed (by sliding) into the design position.

The use of the support system made in this way will allow co787836

to shorten the time of a simple blast furnace at its reconstructions and overhaul.

Claims (2)

1. The blast furnace support system, which contains counters located outside the furnaces and are connected to them. Q beams, different with by the fact that, in order to increase the convenience of the production of works during reconstruction and overhaul and reduce metal consumption, the racks are placed with one 5 sides of the furnace, and the beams are installed on them obliquely with the formation of a console hanging above the top plate, to which the elements of the blast furnace are attached. 2. The system of claim 1, characterized in that the inclined beams are combined with the skip bridge of the furnace, and the racks with the pylon of the skip bridge, while the racks are fastened together, and the beams with the skip bridge - connections of rigidity. 3 S fie.Ь Phi (6 Compiled by L.
