Description
Technical field
The present invention relates to a kind of cement kiln cement-free high-strength wearable material, particularly to a kind of main component
Including corundum aggregate, corundum and silicon carbide micro-powder and the material of silicon ash superfine powder.
Background technology
At positions such as cement kiln head, kiln tail, cooler, tremie pipes, due to complex-shaped, it is difficult to be built into
Type refractory brick, the material generally using ordinary cement to combine is built by laying bricks or stones, but the use environment at these positions is disliked
Bad, the variations in temperature of continuing vigorous makes the thermal shock performance of common material be destroyed, particularly the kiln of rotary kiln
At Kou, constantly being acted on by high temperature chamotte in secondary wind and kiln, every revolution, kiln lining material buries sometimes
Under high-temperature material, being sometimes exposed under flame, temperature difference reaches 200.More than DEG C, influence depth 15-20mm,
This gradient of temperature the most repeatedly, causes the damage of material, peels off, falls the phenomenons such as block.
The material cement consumption that this ordinary cement combines is typically at 12-30%, and water consumption is at 9-13%, due to water
Mud consumption is many, and under middle gentle high temperature, the crystalline phase of calcium aluminate changes and causes intensity to reduce, calcium aluminate
CaO reacts with the composition of material, generate low melting point cacoclasite, cause elevated temperature strength, thermal shock performance and
Corrosion resistance declines；The highest with hourly water consumption, the pore of material is the most, and intensity is the lowest, and construction party is being executed
After work terminates, firing up immediately, because temperature raises very fast, shine into material temperature and drastically raise, internal water
Divide a large amount of evaporation rapidly to produce big expansive force, so that material bursts and peels off, thus kiln maintenance must be stopped,
Affect the production of manufacture of cement producer.
Summary of the invention
The above-mentioned technical problem that the invention solves the problems that there is provided a kind of cement kiln cement-free having following characteristics
High-strength wearable material: life-span length, high temperature resistant, resistant to corrosion, the advantages such as elevated temperature strength is high, thermal shock performance is good.
The cement kiln cement-free high-strength wearable material of the present invention is to solve above-mentioned technical problem, the skill of the present invention
Art scheme is as follows: a kind of cement kiln cement-free high-strength wearable material, original material includes corundum aggregate, corundum
With silicon carbide micro-powder and silicon ash superfine powder, outer doping and anti-knock agent；During construction, adding water carries out mixing and stirs
Mix, uniform application in wall after, carry out maintenance and baking.
The proportioning of the original material of the present invention is:
It is 70-85% that corundum aggregate addition accounts for the percentage ratio of original material gross weight,
It is 5-15% that corundum powder addition accounts for the percentage ratio of original material gross weight,
It is 5-10% that silicon carbide micro-powder addition accounts for the percentage ratio of original material gross weight,
It is 3-8% that silicon ash superfine powder addition accounts for the percentage ratio of original material gross weight
Additionally additive addition accounts for the percentage ratio of original material gross weight is 1-10%
It is 0.1-3% that anti-knock agent addition accounts for the percentage ratio of original material gross weight
It is 2-6% that the addition of water accounts for the percentage ratio of original material gross weight
Wherein additive includes reinforcing agent, toughener, quick dry agent, bonding agent respectively；Including methylcellulose,
Carboxymethyl cellulose, polyvinyl alcohol, dextrin, lignosulfite, polymer alumina, zirconium oxychloride,
Aluminum sulfate, aluminum phosphate, sodium tripolyphosphate, sodium hexameta phosphate, sodium polyphosphate, sodium pyrophosphate, sodium silicate,
One in aluminium powder, aluctyl., two or more are used in combination.
Wherein anti-knock agent is styroflex and carbon fiber；
The wherein granularity 8-5 μm of corundum and silicon carbide micro-powder
Wherein granularity≤5 μm of silicon ash superfine powder
During preparation, carry out mixing and uniform stirring according to above raw material and proportioning, pack packaging；During construction,
Add water after carrying out mix and blend more than 5 minutes, uniform application in wall after, stay dilatation joint 3-5mm every 2m,
Then carrying out maintenance, curing temperature is at 20-40 DEG C, and the time is 3-4 hour, then toasts, and toasts
Cheng Zhong, heating rate is at 20-50 DEG C/h, it is impossible to interrupting or stopping temperature-rise period, temperature is at 600-900 always
DEG C, keep 2 hours.
The present invention uses cement-free to combine, and uses superfine powder to combine and optimal grain mixture ratio, will
Property indices has exceeded the high-strength wearable material that cement-free combines.This invention product granularity reasonable mixture ratio,
Void among particles, is almost stuffed entirely with by superfine powder, and therefore water consumption is down to 2-6%, overcomes common material
Material water is many and that cause pore is many, the defects such as intensity is low.This invention have employed silicon ash superfine powder, is to produce
Metallic silicon or the side-product of Antaciron.In electric arc furnace, quartz is at high temperature reduced into silicon, produces simultaneously
SiO gas, escapes outside stove with flue gas, and SiO runs into air, is oxidized to SiO2, it is collected through dust arrester,
Therefore silicon ash superfine powder low cost, activity is high；It addition, after this product adds silicon ash superfine powder, when construction
Baking and use during, temperature when higher, can and corundum in Al2O3React, formed not come
Stone, thus promote the raising of intensity, thermal shock performance, increase 2-4 times than the strength of materials not adding silicon ash superfine powder.
During construction, adding water and carry out mix and blend more than 5 minutes, the mobility being because material must be in stirring one timing
Between just start to play a role；Further, since this invention consistency is high, bring excellent properties for product, and
Need reserved dilatation joint in rational maintenance, baking regime and construction and it needs to add suitable anti-knock agent；
It is thus desirable to curing temperature is at 20-40 DEG C, the time is 3-4 hour, then toasts, in baking process,
Heating rate is at 20-50 DEG C/h, it is impossible to interrupting or stopping temperature-rise period, and temperature is at 600-900 DEG C always,
Keep 2 hours, the moisture in refractory material so can be made to get rid of smoothly, do not cause any defect, thus carry
The combination property of this invention product high.
The product of this invention is compared with common material product, and cold crushing strength improves 2-4 times, 110 DEG C ×
24h >=180MPa, 1100 DEG C × 3h >=150MPa, bulk density >=2700Kg/m3, life-span increase by 3 times more than.
