Description
Technical field
The present invention relates to cement kiln clinkering zone alkali resistant Mg-Al spinel brick, in particular it relates to a kind of cement kiln clinkering zone
With alkali resistant Mg-Al spinel brick and preparation method thereof.
Background technology
Cement rotary kiln experienced very long differentiation and evolution, at present cement industry kiln mainly by kilneye, descended
Cross band, clinkering zone, lower intermediate zone and set of safety belts into；Because clinkering zone and the working environment of intermediate zone are more severe, so need
Refractory brick is set on clinkering zone and the kiln wall of intermediate zone.Refractory brick in ideal needs to have the characteristics that：1）Excellent
Hang kliner coating performance；2）High heat resistanceheat resistant chemical reaction ability；3）Excellent anti-slag ability；4）Excellent mechanical strength；5）Excellent heat
Shake stability.
But often to having the resource reutilization of various industrial wastes and low-grade former combustion in existing cement rotary kiln
The use of material, cement kiln is turned into the consumer of industrial refuse, made due to the burning of these discarded objects alkali in cement kiln,
Chlorine, the increase of sulfur cycle amount, the erosion to refractory material can aggravate, and sheeting problems are more serious.
The content of the invention
It is an object of the invention to provide a kind of cement kiln clinkering zone alkali resistant Mg-Al spinel brick and preparation method thereof, the water
Stall clinkering zone alkali resistant Mg-Al spinel brick has excellent alkali resistance, while the preparation method has process simple and original
The advantages of material is easy to get.
To achieve these goals, the invention provides a kind of preparation of cement kiln clinkering zone alkali resistant Mg-Al spinel brick
Method, the preparation method include：
1）Magnesium aluminate spinel, pottery sand, silicon powder, urea, hydrazine hydrate, metal chloride and water are subjected to hydro-thermal reaction so that hydro-thermal is made
Reaction product；
2）By bauxite, attapulgite, aluminium ore slag, carborundum, yittrium oxide, quartz sand, hydro-thermal reaction product, lignin sulfonic acid
Calcium, sodium metasilicate, cyclodextrin and water are mixed, are aged so that compound is made；
3）Compound is suppressed so that adobe is made；
4）Adobe is dried, fired, is cooled down so that cement kiln clinkering zone alkali resistant Mg-Al spinel brick is made；
Wherein, spinel particle A, the average grain diameter 0.32-0.45mm that magnesium aluminate spinel is 0.12-0.18mm by average grain diameter
Spinel particle B and average grain diameter be 1.6-2.0mm spinel particle C according to 10：10-15：3-5 weight is than composition；
The metal chloride is made up of nickel chloride, manganous chloride, molybdenum pentachloride, vanadium chloride and palladium bichloride.
Present invention also offers a kind of cement kiln clinkering zone alkali resistant Mg-Al spinel brick, the cement kiln clinkering zone alkali resistant
Mg-Al spinel brick is prepared by upper preparation method.
Burnt till in cement kiln made from the combination that above-mentioned technical proposal, the present invention pass through each raw material and each operation
Band alkali resistant Mg-Al spinel brick has an excellent alkali resistance, while the preparation method has process simple and raw material is easy to get
Advantage.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
