Abstract
The utility model discloses a novel fireproofing tile. The novel fireproofing tile comprises a fireproofing tile body; and two grooves are formed on the bottom surface of the fireproofing tile body in a width direction. The grooves pass through the front and rear sides of the fireproofing tile body. According to the fireproofing tile, the grooves are formed on the bottom surface of the fireproofing tile, so the contact area between the fireproofing tile and a kiln body of a ceramsite kiln is reduced, and the heat loss is reduced; and meanwhile, the grooves are formed on the bottom surface of the fireproofing tile in the width direction, so the structural intensity of the fireproofing tile is guaranteed, the structure of the upper surface of the fireproofing tile is not damaged, and the fireproofing tile can continuously bear the friction and impact which is generated by ceramsite.
Description
Technical field
The utility model relates to a kind of refractory brick, relates to a kind of refractory brick that is used for the haydite kiln in particular.
Background technology
The haydite kiln is a kind of kiln that haydite is carried out preheating and roasting, and it has charging aperture and discharging opening, is provided with the thermal source of heating at the discharging opening place; The haydite kiln is in work, and haydite gets into from the charging aperture of kiln body, through going out from discharging opening after thermal source preheating, the roasting; Temperature is than higher in the time of roasting, and in 1400 deg.c, this temperature has surpassed the temperature that iron and steel melts; In order under this temperature, to make haydite kiln operate as normal; Resistant to elevated temperatures refractory brick all is installed in the kiln body, and the refractory brick that is provided with in the existing haydite kiln is wedge shape, and its width narrows down gradually to the process of end face from the bottom surface.Refractory brick is generally by bauxite, kaolin, and clay, materials such as diatomite are processed; Have resistant to elevated temperatures characteristic,, also do not have any thawing sign even under 1400 ℃ high temperature; But existing refractory brick has certain thermal conductivity, through actual measurement; Adopt the haydite kiln of such refractory brick, it is in the position near discharging opening 1m, and the temperature of haydite kiln outer wall is above 450 ℃; Even arrived the charging aperture place apart from tens meters of discharging openings, the temperature of haydite kiln outer wall also surpasses 200 ℃, and heat scatters and disappears very big.
The utility model content
The purpose of the utility model provides a kind of novel refractory brick, and its thermal conductivity ratio is lower, can reduce scattering and disappearing of haydite kiln heat.
In order to solve the problems of the technologies described above, the technological solution of the utility model is following: novel refractory brick comprises the refractory brick body; Described refractory brick body is being provided with the groove that runs through on its width on the bottom surface.
Described novel refractory brick, described groove are 2.
Described novel refractory brick is filled with the lightweight high-temperature refractory in the described groove.
Described novel refractory brick, described lightweight high-temperature refractory are polycrystalline mullite fibre or polycrystalline alumina fiber or ceramic fibre.
Described novel refractory brick, described refractory brick body has one deck high temperature resistant heat insulation coating in the bottom surface.
The utility model beneficial effect is:
1) bottom surface has groove, has reduced the contact area of refractory brick and haydite kiln kiln body, has reduced scattering and disappearing of heat;
2) groove is opened on the width of refractory brick bottom surface, has guaranteed the structural strength of refractory brick, can not destroy the refractory brick surface structure simultaneously, makes it can continue to sustain friction and the impact of haydite to its generation;
3) be provided with high temperature insulating material in the groove, can further reduce scattering and disappearing of heat.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the front view of the utility model;
Fig. 2 is the left view of the utility model.
Among the figure:
1-refractory brick body, the 101-groove;
2-lightweight high-temperature refractory;
The 3-high temperature resistant heat insulation coating.
The specific embodiment
The following stated is merely the preferred embodiment of the utility model, is not that scope to the utility model limits.
Embodiment sees accompanying drawing 1,2, and novel refractory brick comprises refractory brick body 1; Whole refractory brick body is by bauxite, and resistant to elevated temperatures material such as kaolin is processed, and is low wide and up narrow wedge shape, sees accompanying drawing 1, and as can be seen from the figure refractory brick body 1 is provided with groove 101 on the bottom width direction.The quantity of groove 101 is 2.Groove 101 runs through the width of refractory brick body 1 bottom surface, just runs through its front and back sides.These two grooves 101 are that symmetry is offered, and promptly are convenient to process the structural strength of also being convenient to guarantee the refractory brick body, simultaneously, in order further to strengthen the heat-proof quality of refractory brick, in described groove 101, are filled with lightweight high-temperature refractory 2.Described lightweight high-temperature refractory 2 is polycrystalline mullite fibre or polycrystalline alumina fiber or ceramic fibre.For the effect of heat insulation of further increase refractory brick, described refractory brick body 1 has one deck high temperature resistant heat insulation coating 3 in the bottom surface.The thickness of high temperature resistant heat insulation coating 3 is between 1.0mm-3.0mm, and concrete can select according to the situation of reality.Through these above-mentioned improvement, adopt the haydite kiln of the utility model refractory brick, its heat-proof quality promotes greatly, and through actual measurement, it is in the position near discharging opening 1m, and the temperature of haydite kiln outer wall is about 200 ℃.
