Abstract
A kind of secondary siliceous mullite brick coating, belongs to cement kiln residual heat generating technical field of refractory materials.The percentage by weight of composition is：Each Ingredient percent is：The secondary siliceous mullite brick 45~55% of granularity≤3mm, silicon ash 2~6%, aluminate cement 8~15%, clay 5~10%, the silica brick powder 3~8% of the mesh of high alumina fine powder 10~15%, 180, alumina powder 8~15% separately adds additive.Advantage is waste and old resource is obtained secondary utilization, and the product being made has intensity high, and anti-wear performance is good, easily construction etc..
Description
Technical field
The invention belongs to cement kiln residual heat generating technical field of refractory materials, specifically provide a kind of secondary siliceous mullite brick and apply
Skinning loam.More particularly to a kind of cement kiln residual heat generating with secondary siliceous mullite brick as aggregate high-strength wearable coating.
Background technology
Current about 10,000,000 tons of refractory material of China year consumption, waste and old refractory material reaches 4,000,000 tons, is produced to save industry
The cost of product, the cycling and reutilization of waste and old refractory material is a practical way, and the system of refractory material can be not only greatly lowered
Standby cost, moreover it is possible to bring significant economic and social profit.At present, relevant experimental study shows：Using a high proportion of
Secondary refractory material can be made the products such as refractory brick, castable, the ramming mass of high-quality, and properties of product are accessible or are higher than
The level of original product, therefore, constantly being risen in the fireproof raw material market price, the fire resisting manufactured goods market price but receives user cost
Demand and constantly decline, secondary resistance to material is made full use of, with very real meaning.
In unshape refractory, cement kiln is important application direction.In the pipe-line equipment of cement kiln residual heat generating
Flue gas in there is the features such as dust size is thick, abrasiveness is big, can seriously grind with the stronger clinker particulate of abrasiveness, the particulate
Boiler is damaged, the service life of boiler is reduced.And airduct reducing in waste heat power generation equipment is more, elbow is more, and wind speed is fast, and abrasion is tight
Weight.To meet cogeneration development need, the technological progress of refractory material must be accelerated, the refractory material for cogeneration is necessary
There are high wearability, good alkali resistance, toughness, thermal shock resistance, also good workability.
The content of the invention
It is an object of the invention to provide a kind of secondary siliceous mullite brick coating, solve waste and old siliceous mullite brick cycling and reutilization with
And the problem that refractory material wears no resistance.Product has excellent wearability, and intensity is high, has good workability, and is remarkably improved pot
The service life of the airduct of stove and connection boiler.
A kind of secondary siliceous mullite brick coating, each Ingredient percent is：The secondary siliceous mullite brick 45 of granularity≤3mm~
55%, silicon ash 2~6%, aluminate cement 8~15%, clay 5~10%, the silica brick powder 3 of the mesh of high alumina fine powder 10~15%, 180
~8%, alumina powder 8~15%.
It is another to add additive, account for the 0.02~0.23% of above-mentioned each material summation quality.
Al in secondary siliceous mullite brick2O3Content 60-65wt%, SiC content 5-10wt%, SiO2Content 15-25wt%.
Additive is one or more in sodium tripolyphosphate, carboxymethylcellulose calcium, sodium lignin sulfonate and lithium hydroxide.
The advantage of the invention is that：Recycling for secondary siliceous mullite brick is realized, has been found newly to process secondary siliceous mullite brick
Application direction, and improve the performance of product.The high-strength wearable coating for preparing simultaneously can operate with cement kiln waste heat
The industries such as generating, improve the running rate of equipment；Secondly the secondary siliceous mullite brick of the products application can effectively reduce product cost, produce work
Skill is simple, excellent wear-resisting property, recycles resources circulation.
Specific embodiment
Embodiment 1
A kind of secondary siliceous mullite brick coating, each Ingredient percent is：
The 0.02% of above-mentioned gross weight additive is separately added, additive is sodium tripolyphosphate.
The properties of the high-strength refractory castable produced by present example are as follows：
。
