Abstract
The invention discloses the high-strength anti-chilling castable refractory of breathing freely of one kind, belong to indefinite form technical field of refractory castable.Technical scheme main points are：A kind of high-strength anti-chilling castable refractory of breathing freely, is prepared from by the raw material of following parts by weight：40 50 parts of flint clay, carborundum give up 5 15 parts of fragment of brick, 30 40 parts of mullite, fused alumina zirconia give up 12 parts of 35 parts of fragment of brick, 35 parts of silica, 35 parts of kyanite, 35 parts of aluminum oxide, 46 parts of aluminous cement and metal fiber.Castable refractory produced by the invention has the performance that preferably anti-cold water cold air corrodes, and effectively increases the service life of Thermal Equipment.
Description
Technical field
The invention belongs to indefinite form technical field of refractory castable, and in particular to a kind of high-strength anti-chilling refractory casting of breathing freely
Material.
Background technology
At present, domestic Thermal Corp's cogeneration of heat and power and Thermal Equipment need rapid cooling in process of production, operate repeatedly
Castable is formed, it is damaged in chilling, cause stopping production to change, and the castable used at present can not meet above-mentioned use well
It is required that, the productivity effect of enterprise is have impact on to a certain extent.
The content of the invention
Present invention solves the technical problem that there is provided a kind of stronger high-strength anti-chilling refractory casting of breathing freely of adaptability
Material.
The present invention is to solve above-mentioned technical problem to adopt the following technical scheme that, a kind of high-strength anti-chilling refractory casting of breathing freely
Material, it is characterised in that be prepared from by the raw material of following parts by weight：40-50 parts of flint clay, carborundum give up 5-15 parts of fragment of brick,
30-40 parts of mullite, fused alumina zirconia give up 3-5 parts of fragment of brick, 3-5 parts of silica, 3-5 parts of kyanite, 3-5 parts of aluminum oxide, calcium aluminate
1-2 parts of 4-6 parts of cement and metal fiber.
Further preferably, described high-strength anti-chilling castable refractory of breathing freely is prepared from by the raw material of following parts by weight
's：40 parts of flint clay, carborundum give up 10 parts of fragment of brick, 35 parts of mullite, fused alumina zirconia give up 4 parts of fragment of brick, 4 parts of silica, kyanite 4
Part, 4 parts of aluminum oxide, 6 parts of aluminous cement and 1 part of metal fiber.
Castable refractory produced by the invention has the performance that preferably anti-cold water cold air corrodes, and effectively increases thermal technology
The service life of equipment.
Embodiment
The above to the present invention is described in further details by the following examples, but this should not be interpreted as to this
The scope for inventing above-mentioned theme is only limitted to following embodiment, and all technologies realized based on the above of the present invention belong to this hair
Bright scope.
Embodiment
Raw material is weighed respectively according to following weight proportion（Kilogram）：
1st, the useless fragment of brick 10 of flint clay 40, carborundum, mullite 35, fused alumina zirconia useless fragment of brick 4, silica 4, kyanite 4, aluminum oxide
4th, aluminous cement 6 and metal fiber 1；
2nd, the useless fragment of brick 15 of flint clay 40, carborundum, mullite 30, fused alumina zirconia useless fragment of brick 5, silica 3, kyanite 5, aluminum oxide
3rd, aluminous cement 6 and metal fiber 1；
3rd, the useless fragment of brick 5 of flint clay 50, carborundum, mullite 40, fused alumina zirconia useless fragment of brick 3, silica 5, kyanite 3, aluminum oxide
5th, aluminous cement 4 and metal fiber 2.
Production method：The above-mentioned raw material weighed is well mixed respectively high-strength anti-chilling castable refractory of breathing freely is made,
The castable refractory is adapted in the furnace linings such as thermal kiln furnace, CFB boiler shake construction.
Have been shown and described above the general principle of the present invention, principal character and advantage, do not depart from spirit of the invention and
On the premise of scope, the present invention also has various changes and modifications, and these changes and improvements both fall within claimed invention
Scope.
