Abstract
The invention discloses a high-strength castable with functions of seepage prevention and corrosion resisting. The castable is a novel synthesized dense refractory aggregate Bonite obtained by adding a mineral phase based on calcium hexaluminate (CA6) into a traditional castable formula and remarkably improves the seepage prevention and corrosion resisting properties of a refractory material. Meanwhile, zirconium oxide micro powder is added into the formula, and zirconium oxide is melt into the hexaluminate phase to form a co-melt during calcinations. Accordingly, the sintering activity of the hexaluminate phase is improved, the growth of the hexaluminate phase is promoted, and the dense hexaluminate refractory material can be obtained under a lower addition amount (6-9%) of Bonite. Meanwhile, the sintering temperature is also effectively reduced, so production energy consumption is reduced, production efficiency is improved and energy conservation and emission reduction are facilitated.
Description
Technical field
The present invention relates to technical field of refractory materials, particularly relate to the corrosion-resistant castable of a kind of high-strength antiseepage.
Background technology
Gravity flow pouring material, refers to low cement, ultra-low cement or cement refractory castable with its mixed mobility as spy
Levying, external force is i.e. flowable and degassing without applying to have the castable refractory of this mobility, and without obvious segregation.Due to gravity flow
Castable has good flow behavior, has caused the concern of people in recent years.
The corrosion-resistant castable of high-strength antiseepage is suitable for garbage incinerating system, territory, rotary kiln kiln body discharge zone.For high temperature furnace
When discharging all by erosion in various degree, its feature is, antiacid alkaline residue liquid, the oxidation of anti-fluorine cyanogen, antiscour.
Some in particular cases, barrier performance to castable, under particularly caustic corrosion, metal and regulus corrosion condition
Antiseepage decay resistance require higher, therefore be necessary to study the corrosion-resistant castable of a kind of high-strength antiseepage.
Content of the invention
The technical problem existing based on background technology, the present invention proposes the corrosion-resistant castable of a kind of high-strength antiseepage.
The corrosion-resistant castable of a kind of high-strength antiseepage, including following components in percentage by weight：
Preferably, the particle diameter of described Bo Naite is 320 mesh.
Preferably, the particle diameter of described alumina powder and zirconium oxide micro mist is 250 mesh.
Preferably, described bonding agent is S71 cement.
Preferably, the described corrosion-resistant castable of high-strength antiseepage, including following components in percentage by weight：
Bo Naite is the one novel synthesis of densified refractory aggregate based on calcium hexaluminate (CA6) mineral facies.CA6 has following
Main performance：Very high refractoriness；Solubility in iron content slag is low；Stability in reducing atmosphere (such as carbon monoxide)
High；Chemical stability in alkaline environment is good；Wetability low (iron and steel and non-ferrous metal) to motlten metal and slag.
In extreme conditions, for the bauxite containing BaSO4+silicon powder castable (BX1), Bo Naite's is good
Good aluminum-resistant liquid aggressivity is relevant with its pore-size distribution.In addition to low wetability, the microcellular structure of Bo Naite castable is also that it is high
The rodent reason of aluminum-resistant liquid.
Bo Naite is applied in refractory material as aggregate thus the decay resistance that improves refractory material has obtained extensively
General report, but Bo Naite's is expensive, how to add a small amount of Bo Naite i.e. to can reach the corrosion resistant effect of high-strength antiseepage
It is the emphasis that the present invention studies.
This programme is beneficial in that：The present invention adds zirconium oxide micro mist in formula, in calcination process, and oxidation
Zirconium fuses into formation eutectic in calcium hexaluminate phase, thus improves the sintering activity of calcium hexaluminate phase, promotes calcium hexaluminate phase
Grow up, can obtain fine and close calcium hexaluminate grog refractory under relatively low Bo Naite addition (6-9%), also effectively drop simultaneously
Low sintering temperature, thus reduce energy consumption, improve production efficiency, promote energy-saving and emission-reduction.
