Abstract
The utility model discloses a kind of composite type energy-saving roller aperture bricks, including the identical high intensity brick body of size shape and low heat conduction brick body, it is bonded by refractory mortar between the high intensity brick body and low heat conduction brick body, the high intensity brick body, the middle part of low heat conduction brick body are uniformly set on the center line of length direction there are two perforative circular hole, high intensity brick body, low heat conduction brick body both sides, semicircular through-hole is respectively equipped on the center line of length direction.The heavy brick that the utility model is high using intensity, wearability the is good light-weight brick progress excellent with heat-proof quality is compound, and the weight of club is born by high intensity brick body, and the low heat conduction brick of lightweight does not have to load-bearing, only serves heat-insulated effect.Therefore, the utility model has both the advantages that holding intensity height, excellent wear resistance, excellent heat-proof quality, and in the use of roller kilns, the heat utilization rate of roller kilns will be greatly improved, reduce the defect ware rate of firing product.
Description
Technical field
The utility model belongs to Industrial Stoves renovation technique field, and in particular to a kind of composite type energy-saving roller aperture brick.
Background technology
Roller way kiln is mainly used for the sintering of domestic ceramics as a kind of most commonly seen Industrial Stoves.It is continuously to burn
At kiln its main feature is that burner hearth bottom can install numerous clubs, pass through turning for club using the roller stick of rotation as delivery vehicle
The dynamic transport for realizing article.And club installation need two pieces of roller aperture bricks as fulcrum, usual roller aperture brick is located at both sides furnace wall, because
This has row brick structure with holes in the both sides of roller kilns.Since club desired strength is very high, mostly heavy material, therefore want
Ask the roller aperture brick of both sides that there is preferable performance of weighing, simultaneously as club is in ceaselessly rotating, it is desirable that roller aperture brick has
Fabulous wearability.
In order to ensure there is roller aperture brick preferable load-bearing capacity and wearability, current most of roller kilns all to use heavy
High-alumina brick.But heavy high-alumina brick heat-proof quality is poor, often roller aperture brick position becomes the hot spot of entire furnace wall, compares it
It uses the position of lightweight thermal insulation brick, and temperature will be higher by much stove outside, as a result, on the one hand leading to the neighbouring temperature of club not
Uniformly, the sintering of domestic ceramics is influenced, a large amount of heat-energy losses are on the other hand caused, increases production cost, while can cause
Operating ambient temperature is higher.
Invention content
Goal of the invention：The purpose of this utility model is that in view of the deficiencies of the prior art, one kind is provided and takes into account high intensity, resistance to
The composite type energy-saving roller aperture brick that mill property is good and heat-proof quality is good, is replaced traditional heavy roller aperture brick, not only can effectively be carried
The heat utilization rate of high roller kilns can also improve the qualification rate for firing product, extend the service life of roller kilns.
Technical solution：In order to reach foregoing invention purpose, the utility model is specifically achieved like this：It is a kind of compound
Energy saving roller aperture brick, including the identical high intensity brick body of size shape and low heat conduction brick body, the high intensity brick body and low heat conduction brick
Bonded by refractory mortar between body, the high intensity brick body, the middle part of low heat conduction brick body, on the center line of length direction
It is even to set there are two perforative circular hole, high intensity brick body, low heat conduction brick body both sides, set respectively on the center line of length direction
There is semicircular through-hole.
Wherein, the center of described two circular holes is located at the 1/4 and 3/4 of engineering brick body and low heat conduction brick body long side.
Wherein, the diameter of the circular hole is consistent with through-hole diameter.
Wherein, the circular hole, through-hole perpendicular to high intensity brick body and low heat conduction brick body adhesive surface.
Wherein, the high intensity brick body is one kind in corundum brick, high-alumina brick, alumina hollow ball, clay brick brick, resistance to
Compressive Strength is more than or equal to 10MPa.
Wherein, the low heat conduction brick body uses mullite insulating fire brick, thermal coefficient to be less than or equal to 0.3W/
（m.K）.
Wherein, the refractory mortar can bearing temperature be no more than 1600 DEG C of high temperature, and its thickness is 1 ~ 2mm.
Advantageous effect：The heavy brick that the utility model is high using intensity, wearability is good and the excellent light-weight brick of heat-proof quality
Carry out compound, the weight of club is born by high intensity brick body, and the low heat conduction brick of lightweight does not have to load-bearing, only serves heat-insulated
Effect.Therefore, the utility model has both the advantages that holding intensity height, excellent wear resistance, excellent heat-proof quality, in the use of roller kilns,
The heat utilization rate of roller kilns will be greatly improved, reduce the defect ware rate of firing product.
