Abstract
The invention relates to the technical field of refractory materials and specifically relates to a high-strength refractory castable. The castable is prepared from the following materials in percentage by weight: 10% to 20% of high-alumina clinker, 10% to 20% of pure calcium aluminate cement, 1% to 3% of sodium tripolyphosphate, 4% to 8% of silica micropowder, 20% to 40% of alumina, 10% to 20% of electrically fused magnesite and the balance water. The invention aims to provide the high-strength refractory castable with stable performance and extensive use.
Description
Technical field
The present invention relates to the technical field of refractory material, specifically a kind of high-strength fireproof pour material.
Background technology
In recent years, with the continuous development of China's refractory material and progressively going deep into for every research, make the kind of refractory material
Class and quantity are continuously increased, and quality is increased substantially.Refractory material is the inorganic non-metallic that refractoriness is not less than 1580 DEG C
Material, is the structural material for building the Thermal Equipments such as kiln.In the application of refractory material, unsetting fire proofed wood
Material is excellent with small investment, power consumption province, the entirety liner body good thermal shock stability made, good, the energy fettling of air-tightness etc.
Point, therefore it compared with the sizing refractory material such as refractory brick, application is more extensive.The species of unshape refractory is very
Many, low-cement refractory pouring material is one of them, the more traditional aluminate cement castable refractory of the castable, is had
The advantages of compact high-strength, thixotropy are good, service life is longer.The primary raw material of low-cement refractory pouring material has high alumina bone
Material, high-alumina fly, additive sodium tripolyphosphate and bonding agent silicon powder etc. are constituted, and during use, Jing dry mixing, water are mixed, poured
Injection forming, natural curing, baking are just accused and are completed.Although the castable using effect is preferably, its elevated temperature strength,
Resistance to slag etc. is still unsatisfactory, below 1500 DEG C of Applicable temperature, it is impossible to bear such as cement kiln outlet, clinkering zone for a long time
Deng the mal-condition at position.
The content of the invention
It is to provide a kind of stable performance, widely used high-strength fireproof pour material that the purpose of the present invention is.
The technical solution used in the present invention is that a kind of high-strength fireproof pour material, each material press following weight percent
Than composition：High alumina 10-20%, pure calcium aluminate cement 10-20%, sodium tripolyphosphate 1-3%, silicon powder 4-8%,
Aluminium oxide 20-40%, fused magnesite 10-20%, balance of water.
It is an advantage of the invention that anti-spalling is good, high intensity, be widely used, long service life.
Specific embodiment
The present invention is further described with the following Examples.
Embodiment 1, a kind of high-strength fireproof pour material, each material are constituted by following percentage by weight：High alumina is ripe
Material 20%, pure calcium aluminate cement 10%, sodium tripolyphosphate 1%, silicon powder 8%, aluminium oxide 20%, fused magnesite 20%,
Balance of water.
Embodiment 2, a kind of high-strength fireproof pour material, each material are constituted by following percentage by weight：High alumina is ripe
Material 10%, pure calcium aluminate cement 20%, sodium tripolyphosphate 3%, silicon powder 4%, aluminium oxide 40%, fused magnesite 10%,
Balance of water.
Embodiment 3, a kind of high-strength fireproof pour material, each material are constituted by following percentage by weight：High alumina is ripe
Material 15%, pure calcium aluminate cement 15%, sodium tripolyphosphate 2%, silicon powder 6%, aluminium oxide 30%, fused magnesite 15%,
Balance of water.
It should be understood that the embodiment is only illustrative of the invention and is not intended to limit the scope of the invention.Furthermore, it is to be understood that
After the content for having read instruction of the present invention, those skilled in the art can be made various changes or modifications to the present invention,
These equivalent form of values are equally fallen within the protection domain limited by the application appended claims.
