Abstract
The utility model relates to a furnace door of a medium plate heating furnace, which comprises a door body which is connected with the medium plate heating furnace through a hinge mechanism. The furnace door is characterized in that the door body comprises a grid-shaped rib plate and a door plate connected with the rib plate, and a fire-resistant fiber felt, a fire-resistant anti-vibration layer and a reinforced fire-resistant anti-vibration layer are sequentially fixed on the inner surface of the door plate through an anchor hook arranged on the door plate. The furnace door has the advantages of simple structure, long service life, strong anti-thermal anti-deformation capacity, and capacity of being free from affecting temperature of blank in the heating furnace of the middle plate and improving production quality of the heating furnace of the middle plate effectively.
Description
Technical field
The utility model belongs to metallurgical steel-making and uses equipment technical field, particularly relates to a kind of middle plate Compaction of Heating Furnace Door of anhydrous type.
Background technology
At present, the plate Compaction of Heating Furnace Door is one of critical piece of heating furnace in metallurgical the using, and directly influences the service life and the metallurgical production efficiency of heating furnace the service life of fire door.The high temperature of heating furnace is to influence the fire door principal element in service life, is to increase the fire door main means in service life so improve the heat resistance of Compaction of Heating Furnace Door.In the prior art, Compaction of Heating Furnace Door generally improves its heat resistance by water cooling, and promptly fire door inside is provided with circulating cooling water pipe, and cooling water pipe carries out the water circulation so that fire door is lowered the temperature by water system.
The circulation waterway of above-mentioned fire door water cooling heat resistanceheat resistant structure in being arranged on fire door, also must be provided with the circulating water supply system that is connected with the water route, structure is very complicated, and water system is stopped between long-time, gross distortion then can take place even scrap in fire door, have a strong impact on production safety, maintain and replace cost height.In addition, adopt the water circulation that fire door is cooled off, will certainly the interior temperature of centering plate heating furnace exert an influence, thus the heating quality of the interior blank of plate heating furnace in reducing.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, heat resistance strong, long service life and can not influence in the middle plate Compaction of Heating Furnace Door of blank heating temperature in the plate heating furnace.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: plate Compaction of Heating Furnace Door in a kind of, comprise the door body that is connected with middle plate heating furnace by linkwork, it is characterized in that: described door body comprises netted gusset and the door-plate that is connected with gusset, on the inner face of door-plate by being arranged on anchoring hook fixedly fire-retardent fiber felt-rug, the fire-resistant antidetonation layer and strengthen fire-resistant antidetonation layer successively on the door-plate.
The utility model can also adopt following technical scheme: the netted gusset of rectangle that described netted gusset is made up of horizontal steel plate and vertical steel plate.
Described door-plate is the bending plate body, and door-plate is that bending line is to being provided with the one side bending of anchoring hook with the center line.
Described fire-retardent fiber felt-rug is the high aluminum fiber felt.
Described fire-resistant antidetonation layer waters material feeding for porzite flame-proof.
The fire-resistant antidetonation layer of described enhancing be mixed with the castable refractory of steel fibre in being.
Described netted gusset is provided with stiffener.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly the door body is provided with netted gusset, and netted gusset connects door-plate, has strengthened the non-deformability of door body.The fire-retardent fiber felt-rug that the door-plate inboard sets gradually, fire-resistant antidetonation layer and strengthen fire-resistant antidetonation layer can prolong the service life of door-plate under the environment for use of high temperature, frequent vibrations.Water circulation cooling structure compared to existing technology, the utility model are not only simple in structure, long service life, heat resistanceheat resistant non-deformability are strong, and the temperature of blank exerts an influence in can centering plate heating furnace, has effectively improved the quality of production of middle plate heating furnace.
Door-plate is the bending plate body, and door-plate is bending line with the center line to being provided with the one side bending of anchoring hook, and so structure makes the fire-resistant antidetonation layer of the enhancing interior thickness that is fixed on the door-plate increase, on the one hand, can effectively strengthen strengthening the bonding strength of fire-resistant antidetonation layer, avoid this layer to drop; On the other hand, can reduce near the temperature of the steel plate in fire door center.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is that C-C among Fig. 1 is to view.
Among the figure: 1, door body; 1-1, vertical steel plate; 1-2, horizontal steel plate; 1-3, door-plate; 2, linkwork; 3, stiffener; 4, fire-retardent fiber felt-rug; 5, fire-resistant antidetonation layer; 6, strengthen fire-resistant antidetonation layer; 7, anchoring hook.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, now exemplify following examples, and conjunction with figs. is described in detail as follows: see also Fig. 1 and Fig. 2, a kind of middle plate Compaction of Heating Furnace Door comprises the door body 1 that is connected with middle plate heating furnace by linkwork 2.In the present embodiment, described linkwork 2 is than axle.Door body 1 comprises horizontal steel plate 1-2, vertical steel plate 1-1 and door-plate 1-3.Horizontal steel plate 1-2 and vertical steel plate 1-1 square crossing constitute the netted gusset of rectangle, and door-plate 1-3 is interspersed to be arranged in the netted gusset of rectangle, constitute the door body 1 with rectangular mesh with this.For the intensity of reinforced door body 1, also be welded with stiffener 3 on the netted gusset.Evenly be welded with Y type anchoring hook 7 on the inner face of above-mentioned door-plate 1-3, door-plate 1-3 goes up by anchoring hook 7 fixedly fire-retardent fiber felt-rug 4, fire-resistant antidetonation layer 5 and strengthen fire-resistant antidetonation layer 6 successively, fire-retardent fiber felt-rug 4 is the high aluminum fiber felt, fire-resistant antidetonation layer 5 is a mullite pouring material, is mixed with the castable refractory of steel fibre in strengthening fire-resistant antidetonation layer 6 and being.Above-mentioned door-plate 1-3 Yanzhong alignment is provided with a side bending of anchoring hook 7, and the thickness of fire-retardent fiber felt-rug 4 and fire-resistant antidetonation layer 5 is even, so will strengthen that fire-resistant antidetonation layer 6 is coated with can the thin structure in thick both sides, formation center after flat, this structure more helps strengthening the fixing of fire-resistant antidetonation layer 6, and can reduce near the temperature of the steel plate in fire door center.
