Abstract
The invention relates to a refractory brick, in particular to a composite silicon carbide and mullite refractory brick. The composite silicon carbide and mullite refractory brick comprises an outer magnesite-chrome brick and an inner silicon carbide and mullite brick, wherein the lower surface of the rear side of the magnesite-chrome brick is provided with a notch, and a clamping groove is further arranged at the notch part; and an L-shaped hook body extends out of the lower surface of the front side of the corresponding silicon carbide and mullite brick, the hook body is embedded into the notch and the clamping groove of the magnesite-chrome brick, the magnesite-chrome brick is engaged with the silicon carbide and mullite brick, and a bonding layer is further arranged between the rear side of the magnesite-chrome brick and the front side of the silicon carbide and mullite brick. The composite silicon carbide and mullite refractory brick provided by the invention consists of the outer magnesite-chrome brick and the inner silicon carbide and mullite brick, and the two kinds of brick bodies are engaged with each other so that the brick cannot fall apart; by utilizing the different properties of the two brick bodies, not only is fire resistance improved, the wear resistance is also improved, and the whole fire resistance and shock resistance are improved; and through vertical engagement, the firmness of the whole heat preserving layer is improved, and the service life of the heat preserving layer is prolonged.
Description
Technical field
The present invention relates to a kind of refractory brick, especially comprehensive silicon not refractory brick.
Background technology
Cement rotary kiln clinkering zone, needs to bear bigger pressure, also requires there is certain heat-insulating property, simultaneously resistance to
Mill.Currently used cement rotary kiln clinkering zone liner is substantially fireproof insulation brick and refractory brick monolithic architecture forms, and makes for a long time
With gap can be produced between fireproof insulation brick and refractory brick, cause refractory brick to loosen and even drop, affect the longevity of fireproof insulation brick
Life and heat insulation effect, and refractory brick due to long-term under high temperature and rolling friction service life shorter, change refractory brick and be intended to
All being dismantled by refractory brick around the refractory brick of damage and again spread, maintenance inconvenience, maintenance time is long, and impact produces.
Summary of the invention
For solving the problems referred to above, the present invention provides the comprehensive silicon not refractory brick of a kind of difficult drop-off, high insulating effect, specifically
Technical scheme is:
Comprehensive silicon not refractory brick, including magnesite-chrome brick and the siliceous mullite brick of inner side in outside；On rear side of described magnesite-chrome brick, lower surface is jagged,
Indentation, there also has a draw-in groove；On front side of corresponding siliceous mullite brick, lower surface extends the coupler body of a L shape, and described coupler body is embedded into magnesium
In the breach of chrome brick and draw-in groove, magnesite-chrome brick and siliceous mullite brick are interlocked, on rear side of described magnesite-chrome brick and siliceous mullite brick on front side of it
Between also have tack coat.
Described siliceous mullite brick upper surface has projection, and corresponding lower surface is fluted, between neighbouring siliceous mullite brick, lower floor
Projection is inserted in the groove of upper strata siliceous mullite brick.
The comprehensive silicon not refractory brick that the present invention provides, is made up of the magnesite-chrome brick in outside and the siliceous mullite brick of inner side, two kinds of brick body
Between be mutually twisted composition, difficult drop-off, and utilize two kinds of brick body different qualities, i.e. improve fire resistance and also improve wear-resisting
Performance, overall fire-resistant anti-seismic performance improves, and by being engaged up and down, improves the fastness that heat-insulation layer is overall, extend guarantor
Temperature layer service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The detailed description of the invention of the present invention is described, as shown in Figure 1 in conjunction with accompanying drawing: comprehensive silicon not refractory brick, including outside
Magnesite-chrome brick 1 and the siliceous mullite brick 2 of inner side；On rear side of described magnesite-chrome brick 1, lower surface is jagged, and indentation, there also has a draw-in groove；Corresponding
On front side of siliceous mullite brick 2, lower surface extends the coupler body 6 of a L shape, and described coupler body 6 is embedded in breach and the draw-in groove of magnesite-chrome brick 1,
Magnesite-chrome brick 1 and siliceous mullite brick 2 are interlocked, on rear side of described magnesite-chrome brick 1 and on front side of siliceous mullite brick 2 between also have tack coat 5.
Described siliceous mullite brick 2 upper surface has a projection 3, corresponding lower surface fluted 4, between neighbouring siliceous mullite brick, under
The projection of layer is inserted in the groove of upper strata siliceous mullite brick.
This comprehensive silicon not refractory brick, is made up of the magnesite-chrome brick 1 in outside and the siliceous mullite brick 2 of inner side, between two kinds of brick body mutually
Occlusion composition, difficult drop-off, and utilize two kinds of brick body different qualities, and i.e. improve fire resistance and also improve anti-wear performance, whole
The fire-resistant anti-seismic performance of body improves, and by being engaged up and down, improves the fastness that heat-insulation layer is overall, extends heat-insulation layer and uses
Life-span.
