Abstract

The utility model provides the technical scheme of a glass-ceramic plate for sluiceways, which belongs to a sluiceway accessory of a blast furnace. The technical scheme includes that an L-shaped glass-ceramic plate is provided with a vertical edge and bottom flat edge, at least two dovetail grooves are arranged on the outer side of the vertical edge, the dovetail grooves of the vertical edge are parallel to each other and arranged horizontally, and at least two bolt holes penetrating through the vertical edge are arranged on the vertical edge and provided with bolt head slots on the inner side of the vertical edge. By aid of the structure, when the glass-ceramic plate is bonded with a sluiceway outer die via bonding materials such as concrete, the glass-ceramic plate is firmly bonded with a bonding layer and not easy to be stripped by aid of the dovetail grooves at the vertical edge. Bolts can be inserted into the bolt holes during bonding, each bolt forms a rivet between the bonding layer and the glass-ceramic plate so as to rivet and fix the glass-ceramic plate, and then the shortage that the glass-ceramic plate is easy to be stripped during usage can be avoided.

Description

A kind of sluice glass cermaic plate

Technical field:

The utility model relates to the sluice accessory of a kind of blast furnace in the metallurgy industry, especially a kind of sluice glass cermaic plate.

Background technology:

The sluice of iron-smelting blast furnace is to be made of external mold and liner, because interior slag of sluice and water flow velocity are bigger, and, also have acidity, so comparatively serious to the wearing and tearing and the corrosion of sluice liner.In the prior art, known sluice liner is to adopt the orthogonal glass cermaic plate to assemble to form, because glass cermaic plate has wear-resisting and corrosion resistant characteristics so can satisfy the requirement of sluice.But; the adhesive property of glass cermaic plate is bad; be easy to come off with the external mold of sluice; therefore; the glass cermaic plate that is in operation comes off and will cause the sluice external mold to lose the protection liner; make the sluice external mold be subjected to heavy wear and corrosion, even can cause stopping production, this is the existing in prior technology weak point.

Summary of the invention:

The purpose of this utility model, be exactly at the existing in prior technology deficiency, and a kind of sluice technical scheme with glass cermaic plate is provided, this scheme is processed into glass cermaic plate the L shaped plate on the flat limit of the stile and the end, the outside at stile also has dovetail-indent, this structure, because the existence of dovetail-indent is arranged, when between glass cermaic plate and sluice external mold, boning with matrix materials such as concrete, dovetail-indent can make the glass cermaic plate tack coat of holding effectively, promptly form can not " demoulding " state, therefore, in use just avoided the disadvantage that comes off easily.

This programme is realized by following technical measures: the characteristics of this programme are L shaped glass cermaic plates that the flat limit of the stile and the end is arranged, and in the outside of stile at least two dovetail-indents are arranged.The concrete characteristics of this programme also have, and each dovetail-indent in the described stile outside is parallel to each other, and is horizontal.On described stile, also have two keyholes that penetrate stile at least.Described keyhole has bolt head groove at the medial surface of stile.

The beneficial effect of this programme can be learnt according to the narration to such scheme, because the glass cermaic plate in this scheme is a L shaped glass cermaic plate that the flat limit of the stile and the end is arranged, at least two dovetail-indents that are parallel to each other are arranged in the outside of stile, and on described stile, also have two keyholes that penetrate stile at least.This structure, because the existence of dovetail-indent is arranged in the glass cermaic plate stile outside, when boning with matrix materials such as concrete between glass cermaic plate and the sluice external mold, the dovetail-indent on the stile can make the glass cermaic plate tack coat of holding be difficult for peeling off effectively.In addition, on stile, also have keyhole, but this keyhole inserting bolt when bonding, and bolt just constitutes a rivet between tack coat and glass cermaic plate, rivet clasp glass cermaic plate, therefore, glass cermaic plate has in use also just been avoided the disadvantage that comes off easily.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the A-A sectional structure synoptic diagram of Fig. 1.

Among the figure, 1 is flat limit, the end, and 2 is stile, and 3 is keyhole, and 4 is bolt head groove, and 5 is dovetail-indent.

Embodiment:

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.

By accompanying drawing as can be seen, the sluice glass cermaic plate of this programme is a L shaped glass cermaic plate that the flat limit of the stile and the end is arranged, and with flat limit opposing L shape glass cermaic plate at the bottom of two, has just constituted one section flute profile glass cermaic plate liner of sluice.In the outside of glass cermaic plate stile at least two dovetail-indents are arranged, what this embodiment adopted is five dovetail-indents.Be parallel to each other between each dovetail-indent in the described stile outside, and be horizontal.But have two keyholes that penetrate the stile inserting bolt on described stile at least, this embodiment adopts two keyholes exactly.Described keyhole has bolt head groove at the medial surface of stile, is used to imbed the bolt head on the bolt.

Claims (4)

1. sluice glass cermaic plate, it is characterized in that: glass cermaic plate is a L shaped glass cermaic plate that the flat limit of the stile and the end is arranged, and in the outside of stile at least two dovetail-indents is arranged.

2. glass cermaic plate according to claim 1 is characterized in that: each dovetail-indent in the described stile outside is parallel to each other, and is horizontal.

3. glass cermaic plate according to claim 1 and 2 is characterized in that: also have two keyholes that penetrate stile on described stile at least.

4. glass cermaic plate according to claim 3 is characterized in that: described keyhole has bolt head groove at the medial surface of stile.
