The invention relates to electrothermal and can be used in the construction of samospekavkhsya electrodes of arc furnaces. · $

The purpose of the invention is to reduce the complexity of manufacturing and ease of assembly.

FIG. 1 shows the electrode housing, a general view; in fig. 2 - section A-A on the south of FIG. one; in fig. 3 shows the node I in FIG. 1 (view of the vertical slot); in fig. 4 shows a section BB in FIG. 3,

The casing of the self-caking electrode contains lindrical sections 1, which are welded to each other between the cylinders, which consist of shells 2 and ribs 3.

The ribs 3 have a cross-sectional shape of an non-equilateral angle, while the small shelf 4 ribs with an outer side is welded to the inner surface of the shell 2.

In the upper part, the edge 3 also has a small shelf 5, offset to the center of the shell 2 by an amount equal to or greater than the thickness of the small shelf 4 of the rib 3, and protruding above the upper end 6 of the shell 1.

In the lower ends 7 of each shell 2, vertical 30 slots 8 are opened downwards. Inside the shell 2, opposite the side surfaces 9 of the vertical slots, there is an edge of a small shelf 4 ribs 3.

Upper end 6 of each shell 2 35

has a cylindrical band 10 flanged to the center of the shell 2, while the outer diameter of the cylindrical belt 10 is smaller than the inner diameter of the shell 2 ″. If there is a cylindrical belt 10, the edge 3 in the lower part of section 1 is installed at some distance from the lower end 7 of the shell 2, commensurate with the width of the cylindrical belt 10. 45

The ribs 3 of the adjacent abutting cylindrical sections are welded to each other at the junction of the end of the small flange 4 of the ribs 3 to the outer side of the small flange 5 by a welding seam 11 overlap, and the vertical slot formed by the inner side surface 9 of the slot and the welding seam 11 is welded by the seam 12. The joint between the lower end 7 of the upstream shell and the downstream section 1 is welded with a welding seam 13.

18 4

The Assembly of the cylindrical sections of the casing self-caking electrode is as follows.

The expandable section 1 is installed with a crane until it touches the lower section 1 so that in the expandable section 1 the inside of the small shelf 4 of the ribs .3 overlaps the outside of the small shelf 5 of the edges 3 protruding above the upper end 6 of the lower section 1.

After that, the shells 2 are welded with an annular weld seam 13, then the edges of the 3 joined shells 2 are welded in the vertical slot 8 with the welding seam 11 and the vertical gap is welded between the side surface 9 of the vertical slot 8 with the butt seam 12. As a result of this assembly, a tight joint of sections 1 is provided.

The invention allows to simplify the design of the casing self-caking electrode, to reduce the complexity of manufacturing sections of the casing, to facilitate the process of assembling and mounting the casing and to reduce the time spent when building sections of the casing self-caking electrode.

Claims (2)

Claim 1. A casing of a self-curing electric arc of an electric arc type, containing sections welded together, consisting of a shell with ribs attached to it from the inside, made in the form of unequal angles protruding above the upper edge of the shell, and vertical slots in the lower part of the shell are made , characterized in that, in order to reduce the complexity of manufacturing, a small shelf of each edge is made with a bend in the upper part to the center shell, and the edge is set by the edge of a small ’shelf opposite the vertical slot. 2. Casing pop. 1, characterized in that, in order to facilitate assembly, the ribs in the lower part of the section are installed from the end of the shell at a distance less than the height of the corners protruding above the upper edge of the shell. 1504818 Aa Thebes.2 FIG. 3
