Abstract
The utility model discloses a low-thermal-conductivity composite brick. The low-thermal-conductivity composite brick comprises a silicon mullite brick on the upper layer and a high-alumina brick on the lower layer. A groove hole is formed in the bottom of the high-alumina brick, and aluminum fiber cotton is accommodated in the groove hole. The low-thermal-conductivity composite brick improves heat-insulating property, ensures strength and refractoriness of light portions, further improves abrasive resistance and corrosion resistance, and meanwhile improves thermal shock resistance. The design of the bottom reduces the friction force between the composite brick and a rotary kiln, prolongs service life of the composite brick and the rotary kiln, and greatly reduces production cost.
Description
Technical field
The utility model belongs to fire resisting material field, is specifically related to a kind of low heat conduction composite brick.
Background technology
Along with constantly bringing forth new ideas of technology of producing cement, the manufacture of cement main process equipment develops to the maximization direction, the key that increase output, improve the quality, save energy and reduce the cost, Jiangdu cost becomes increase benefit in the production management.Existing refractory brick and insulating brick mostly structure are single, need during use the brick of all kinds of performances is used, if on relatively-stationary equipment, as tunnel cave, are used also and can meet the demands; But on the equipment of some relative motions, as rotary kiln, be used and just be difficult to meet the demands.At present, now domestic producer withdraws from the composite brick of some lightweights and heavy combination, but no matter light-weight brick or the design of heavy brick are in lower floor, with the phase mutual friction of rotary kiln junction, in the course of time can cause composite brick and rotary kiln to impact, thereby reduce operating efficiency, improve maintenance cost.
Summary of the invention
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of low heat conduction composite brick is provided.
Technical scheme: in order to reach the foregoing invention purpose, the utility model is specifically finished like this: a kind of low heat conduction composite brick, comprise the siliceous mullite brick on upper strata and the high-alumina brick of lower floor, and described high-alumina brick bottom has slotted eye, is filled with the aluminum fiber cotton in the slotted eye.
Wherein, between described siliceous mullite brick and the high-alumina brick by cement-bonded.
In order to mate the shape of rotary kiln, described composite brick cross section can be designed to rectangle, trapezoidal or hexagon.
Beneficial effect: the utility model compared with prior art improves heat-proof quality, and guarantees intensity and the refractoriness at lightweight position, has further improved wearability and corrosion resistance, has also improved thermal shock resistance simultaneously; The design of bottom has reduced the frictional force of composite brick and rotary kiln, has increased the service life of composite brick and rotary kiln, greatly reduces production cost.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
As shown in drawings, a kind of low heat conduction composite brick that the utility model provides comprises the siliceous mullite brick 1 on upper strata and the high-alumina brick 2 of lower floor, described high-alumina brick 2 bottoms have slotted eye 3, be filled with the aluminum fiber cotton in the slotted eye 3, by cement-bonded, the composite brick cross section is rectangle between described siliceous mullite brick 1 and the high-alumina brick 2.
Claims (3)
1. one kind low heat conduction composite brick is characterized in that, comprises the siliceous mullite brick (1) on upper strata and the high-alumina brick (2) of lower floor, and described high-alumina brick (2) bottom has slotted eye (3), and slotted eye is filled with the aluminum fiber cotton in (3).
2. low heat conduction composite brick according to claim 1 is characterized in that, between described siliceous mullite brick (1) and the high-alumina brick (2) by cement-bonded.
3. low heat conduction composite brick according to claim 1 and 2 is characterized in that, described composite brick cross section is rectangle, trapezoidal or hexagon.
