Abstract

The utility model provides a depletion electric stove furnace roof structure, hang roof beam, jib, hang frame, lifting hook and resistant firebrick including what top-down set gradually, it sets up to the spandrel girder to hang the roof beam, the upper end and the lower extreme of jib are fixed with hanging the roof beam respectively and hanging frame swing joint and accessible nut, the upper end and the lower extreme of lifting hook respectively with hang frame and resistant firebrick fixed connection. The utility model discloses a to hang the roof beam and set up to the spandrel girder and on refractory material, just so need not adopt the conventional water-cooling H type crossbeam that buries at refractory material as bearing atress component to can avoid leaking the danger that brings for the furnace body because of water-cooling H type crossbeam.

Description

Furnace top structure of dilution furnace

Technical Field

The utility model belongs to the technical field of metallurgical chemical industry, in particular to a depletion electric furnace top structure.

Background

In the metallurgical chemical industry, the existing furnace top structure of the dilution furnace generally adopts a water-cooling H-shaped cross beam as a bearing stress member, and the water-cooling H-shaped cross beam is buried in a refractory castable. Because the copper pipe in the H-shaped cross beam is easy to corrode or is broken down due to electrode arcing, water leakage is caused and the safety of the furnace body is endangered, the structure not only shortens the service life of the furnace body, but also the refractory castable is difficult to replace.

SUMMERY OF THE UTILITY MODEL

In view of the above prior art, the to-be-solved technical problem of the present invention is to provide a furnace top structure of an electric dilution furnace, which has a simple and reasonable structure and is convenient to maintain.

In order to solve the technical problem, the utility model provides a depletion electric stove furnace roof structure, hang roof beam, jib, hang frame, lifting hook and resistant firebrick including what top-down set gradually, it sets up to the spandrel girder to hang the roof beam, the upper end and the lower extreme of jib are fixed with hanging the roof beam respectively and hanging frame swing joint and accessible nut, the upper end and the lower extreme of lifting hook respectively with hang frame and resistant firebrick fixed connection.

More preferably, the thickness of the refractory brick is 350-450 mm.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the hanging beam is arranged as the bearing beam and is arranged on the refractory material, so that the conventional water-cooling H-shaped beam buried in the refractory material is not needed to be used as a bearing stress component, and the danger of the furnace body caused by water leakage of the water-cooling H-shaped beam can be avoided.

2. Simple and reasonable structure, convenient maintenance and longer service life.

Drawings

FIG. 1 is a schematic view of a structure of a blast furnace roof of the cleaning furnace of the present invention.

Illustration of the drawings: 1-hanging beam, 2-hanging rod, 3-hanging frame, 4-hanging hook and 5-refractory brick.

Detailed Description

The invention will be further described with reference to the drawings and preferred embodiments.

Fig. 1 is a schematic view of the furnace top structure of the impoverishment furnace of the present invention, which comprises a hanging beam 1, a hanging rod 2, a hanging frame 3, a hanging hook 4 and a firebrick 5 arranged in sequence from top to bottom. Wherein, the hanging beam 1 is arranged as a bearing beam, so that the whole weight of the furnace top can be born by the hanging beam 1; the lower part of the hanging beam 1 is fixedly provided with a plurality of hanging rods 2 through nuts, the lower ends of the hanging rods 2 are also provided with threads, the hanging rods can be fixedly connected with a hanging frame 3 through the nuts, and the height of the hanging frame 3 can be adjusted through the up-and-down movement of the nuts; hang frame 3 and set up to the rack that becomes by the band steel welding, its accessible a plurality of lifting hook 4 and resistant firebrick 5 fixed connection, and the thickness of resistant firebrick is 350 ~ 450 mm. The utility model discloses a to hang the roof beam and set up to the spandrel girder and on refractory material, just so need not adopt the conventional water-cooling H type crossbeam that buries at refractory material as bearing atress component to can avoid leaking the danger that brings for the furnace body because of water-cooling H type crossbeam.

The foregoing merely illustrates preferred embodiments of the present invention, which are described in considerable detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes, modifications and substitutions can be made, which are all within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.

Claims (2)

1. A blast furnace roof structure characterized by: the hanging beam, the hanging rod, the hanging frame, the lifting hook and the refractory brick are sequentially arranged from top to bottom, the hanging beam is arranged to be a bearing beam, the upper end and the lower end of the hanging rod are respectively movably connected with the hanging beam and the hanging frame and can be fixed through nuts, and the upper end and the lower end of the lifting hook are respectively fixedly connected with the hanging frame and the refractory brick.

2. A lean furnace roof structure according to claim 1, wherein: the thickness of the refractory brick is 350-450 mm.
