Description
Technical field
The utility model relates to fire resisting material field, particularly a kind of Novel fireproof brick.
Background technology
Existing refractory brick, if application number is refractory brick disclosed in the Chinese patent of 2011204553142, refractory brick and rotary kiln lean on the metal shell of refractory brick to touch, can deformation be there is in metal shell after being subject to the heat intensification of refractory brick transmission, this deformation extruding refractory brick, it is the major reason that refractory brick breaks, in order to ensure that the intensity of refractory brick is to resist Metal Deformation, make refractory brick life higher, application number is disclose the refractory brick comprising working lining and thermal insulation layer double-layer structure in the Chinese patent of 201420360800X, strengthens heat-insulating capability and the rigidity of refractory brick.Air is the insulation medium being better than refractory brick brick body, but in refractory brick brick body, added multiple air layer for after heat insulation, refractory brick Stiffness can be caused, thus be easy to damaged, in above-mentioned two kinds of prior art, all have employed mode heat dam being set near one end of metal shell at refractory brick and strengthen effect of heat insulation further, but be exactly the insufficient rigidity of refractory brick with the problem that this brings.
Summary of the invention
The object that the utility model will reach is to provide a kind of Novel fireproof brick, ensures the rigidity of refractory brick while improving refractory brick heat-insulating capability.
In order to achieve the above object, the utility model adopts following technical scheme: Novel fireproof brick, described refractory brick comprises thermal insulation layer and working lining, working lining is provided with projection along a side of refractory brick width, thermal insulation layer is provided with the groove corresponding with the projection of working lining, the projection of working lining embeds in the groove of thermal insulation layer, described thermal insulation layer is provided with heat dam away from a side of working lining, heat dam extends along the direction being parallel to place side, the wall of high temperature zirconium cotton is provided with in heat dam, wall covers heat dam inwall, heat insulation is provided with in heat dam, heat insulation and wall are fitted, heat insulation is provided with some insulation holes, the aperture of insulation hole is 9mm-11mm, the pitch of holes in adjacent insulation hole is 7mm-9mm.
Heat insulation is added in the heat dam of refractory brick, wall is provided with between heat dam and heat insulation, wall is made up of high temperature zirconium cotton, heat insulation, wall, thermal insulation layer, working lining can be interconnected successively and be structure as a whole, heat insulation has filled up the vacancy of heat dam, thus improve the rigidity of refractory brick, the insulation hole be provided with in heat insulation can form the effect of approximate air heat-insulation layer, make the heat dam of refractory brick be filled up rear heat-proof quality can not decline to a great extent, wall substantially increases the heat-proof quality of refractory brick further, the heat transmission that metal shell is subject to declines, thus the temperature of metal shell declines, the deformation that metal shell occurs reduces, the extruding force that refractory brick produces is declined, although thus the rigidity of refractory brick decreases because of the existence of insulation hole, but the external force that refractory brick is subject to also reduces simultaneously, be equivalent to the rigidity that ensure that refractory brick.
Further, described heat insulation comprises two end faces on heat insulation length direction, and the insulation hole nearest from end face and the spacing of end face are 8mm-10mm, guarantee the bonding strength of heat insulation and thermal insulation layer.
After adopting technique scheme, the utility model tool has the following advantages:
The rigidity of refractory brick is ensured while improving refractory brick heat-insulating capability.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
