Technical field
The present invention relates to technical field of refractory materials, it is related to a kind of refuse furnace wear-resistant castable.
Background technology
The furnace construction such as alkaline refuse furnace position has alkaline atmosphere composition weight, and clinker and heat smoke souring are strong, ring
The border temperature difference is big, the special operation condition condition such as refractoriness height, and higher to the index request of capabilities of refractory materials, conventional products typically make
It is the corundum porzite flame-proof castable that cement is combined, the problem of it is present has：The thermal coefficient of expansion of corundum than larger,
Thermal shock resistance is bad, and corundum is changed into β phase corundum in cement kiln alkaline atmosphere by α phase corundum, causes volumetric expansion, easily causes
Structure is destroyed, intolerant to alkaline attack so that the life-span of coal injection pipe shortens dramatically, the need for can not meeting market.At present, it is new
Dry cement production line scale expands day by day, and in order to improve the running rate of whole firing system, strengthens the market competitiveness of enterprise,
New Type Dry-process Cement Production enterprise is applied to wherein in the urgent need to high-quality castable refractory.
The traditional construction mode of castable is constructed for vibration, there are some shortcomings, for example, vibrator undervibration causes to pour
Not enough, overvibration particle easily produces segregation to injection body density, and easily leaves cavity during vibrating head insertion extraction, in addition vibrator
There is noise pollution, influence construction environment.
The content of the invention
The present invention will provide refuse furnace wear-resistant castable, and it is brilliant that the refuse furnace wear-resistant castable can improve institutional framework
Phase structure uniformity, optimizes body of material explosion-proof performance, and then obtains that a kind of corrosion resistance is good, alkali resistant splits, good thermal shock,
It is wear-resistant, change traditional construction mode, prepared using from stream mode, a kind of castable of easy construction.
The concrete technical scheme that the present invention is used is as follows：
A kind of refuse furnace wear-resistant castable, including following components raw material and parts by weight：30-50 parts of 15-0mmA88 spinelles,

5-8 parts of zirconium gel powder, particle diameter is less than 1 μm of 3-8 part of silicon powder, Al of the particle diameter less than 1.2 μm2O33-5 parts of micro mist, silicate
625 1-3 parts of cement, 3-8 parts of magnesium colloidal sol, 0.12 part of sodium pyrophosphate, 0.15 part of defoamer, 0.3 part of explosion-proof fiber, aluminium carbonate
0.2 part.
It is preferred that, the A88 spinelles include 15-8mm, 3-8mm and 0-3mm particle.
It is preferred that, the composite inorganic powder is that mass ratio is 1:2：1：1 andalusite, kyanite, sillimanite and modification is not
Carry out the combination of stone flour.
It is preferred that, the defoamer agent is the PA-311 and TCB-1 of crop field chemical production.
It is preferred that, the heat-resistant steel fiber main component is Fe, Ni and Cr, in addition to micro Nb, Mn and C, Yi Jiji
Micro Si, P and S；Specifically component ratio is：Ni-40wt%, Cr-16wt%, Nb-10wt%, Mn-5wt%, C-0.5wt%, Si-
Below 0.1wt%, below P-0.1wt%, below S-0.1wt%, surplus are Fe.
It is preferred that, the explosion-proof fiber is 3 μm of diameter, and length 7mm, fusing point is less than 90 degree of polymer fiber.
Preferential, the fineness of the aluminium carbonate is 180 mesh.
It is a further object to provide a kind of preparation method of refuse furnace wear-resistant castable.
A kind of preparation method of refuse furnace wear-resistant castable, comprises the following steps：A. by above-mentioned raw materials（Magnesium colloidal sol is removed
Outside）Pour into agitating device, mixing is stirred at room temperature；B. the magnesium colloidal sol for adding 3-8% stirs；C. the material injection being stirred
Mould, band mould is dried after conserving 48h, demoulding maintenance 36-48h；D. 300 insulation 6h are warming up to 5 DEG C/min, with 10 DEG C/min
It is warming up to 1300 DEG C of insulation 4h, you can obtain product.
Beneficial effects of the present invention are as follows：
The present invention, as aggregate, utilizes the hardness height of spinelle, the characteristics of wearability is good, to improve castable using spinelle
Anti-wear performance and erosion-resisting characteristics；Composite inorganic powder is andalusite, kyanite, sillimanite and modified mullite powder group in castable
Close, andalusite, sillimanite are irreversibly converted into mullite and SiO at high temperature2, SiO2It is substantially inside mullite crystal,
The SiO being softened at high operating temperatures in mullite crystal2Volume Changes caused by temperature change can be absorbed, while aquamaine
The mullite conversion temperature of stone is low compared with andalusite, can form the mullitization reaction of gradient distribution, can be avoided to obtain same
The expansion of sample, all avoids concentrating the caused crackle of expansion using andalusite；Modified mullite used at the same time belongs to a kind of sub-
Kaolin, can absorb the alkaline matter in kiln atmosphere during use, also can continue mullitization with kiln temperature change,
Playing optimization matrix of materials improves material property effect, and three can realize perfect combination to avoid a kind of product not
Foot.By defoamer PA-311 and TCB-1 compound addition, bubble can be preferably eliminated, gas is more easy to discharge, improves stomata
Distribution, it is to avoid inequality, which is homogenized, inside castable avoids material segregation, and 0.15 part of usage amount is proper, more than 0.15 part
Material property is influenceed, less than 0.15 part bubble can not be excluded fully.Zirconium gel powder is added, silicon powder, magnesium colloidal sol, aluminum oxide is micro-
Powder, the cement of silicate 625 can form magnesia spinel forsterite zirconium silicate composite construction so that the principal crystalline phase of matrix is many
Item composite construction, it is engaged to each other, structural homogenity between castable crystalline phase is improved, and then improve the entirety of castable
Performance；Invention also uses aluminium carbonate, explosion-proof fiber is compound to prevent the explosion of castable, and explosion-proof fiber is soft in fire process
Change, shrink, fusing, eventually form stomata and be carbonized, aluminium carbonate can after being cast with water generated reactive gas, in material internal shape
Into small network stomata, aqueous vapor passage is formed, lightening material internal stress improves thermal shock resistance, extends the use longevity of castable
Life, the product after decomposition is active aluminium hydroxide again, can be with component formation high-temperature-phase material in system.
In addition, the present invention changes traditional construction mode, can be automatic stream using vibrator vibration from stream mode, is not required to
Move, shakeout, closely knit and solidification, it is to avoid the problems such as the castable segregation that vibration construction may be brought, while the compound froth breaking of addition
Agent makes castable possess good froth breaking exclusion gas function.The present invention carries out inside to castable using heat-resistant steel fiber and added
Gu, heat-resistant steel fiber rough surface can combine closely with the powder after wetting and play certain supporting role, contribute to castable
It is quickly moulding.With traditional castable ratio, magnesium colloidal sol complex abrasion-proof castable high volume stability is good, alkali resistant corrodes, antiknock
Split, service life is long.
