Abstract
The invention discloses a formula of silicon carbide spray coating, comprising the following components: silicon carbide, mullite, alumina micropowder, silica micropowder and compound additive composed of sodium tripolyphosphate and methylcellulose. The formula comprises the following components in percentage by weight: 10-40% of the silicon carbide, 40-60% of the mullite, 10-20% of the alumina micropowder, 0-15% of the silica micropowder and 0-2% of the compound additive. When the spray coating prepared by the formula of the invention is used for spraying a rotary cement kiln, a spraying layer has small possibility of falling and has good stability and long service life.
Description
Technical field
The present invention relates to a kind of spray material that is used for dry method cement rotary kiln.
Background technology
Along with developing rapidly of domestic new type nonaqueous cement rotary kiln, under the effort of person skilled, refractory materials has all been realized production domesticization in the kiln at home.Particularly a large amount of utilizations of unshape refractory are for cement production enterprise has reduced many times when going into operation and building by laying bricks or stones.But, when using traditional product, when the mould material at positions such as kiln hood cover, tertiary-air pipe comes off, generally, must stop kiln more than one day, when equitemperature drops to room temperature, the workman just can enter and prize the part mould material in the kiln, and formwork erection is manually poured into a mould again again, and also need maintaining after the cast could light a fire more than 3 days again puts into production, off-time is very long, construction labour intensity is big, and, like this mould material and original remaining lining to combine effect undesirable, come off easily after using for some time, work-ing life is shorter.Only be about half a year refractory materials its work-ing life as the kiln hood cover place after repairing.
Summary of the invention
Technical problem to be solved by this invention just provides the siliceous spray material prescription of a kind of carbonization, and the spray material that uses this prescription to make sprays cement rotary kiln, sprayed coating difficult drop-off, good stability, long service life.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the siliceous spray material prescription of a kind of carbonization, it is characterized in that: the component of described prescription comprises silicon carbide, mullite, alumina powder.
As preferably, the component of described prescription also comprises silicon powder.
Further, the component of described prescription also comprises the composite additive that tripoly phosphate sodium STPP and methylcellulose gum are formed.
As preferably, the weight percent of each component is silicon carbide 10-40%, mullite 40-60%, alumina powder 10-20%, silicon powder 0-15%, composite additive 0-2% in the described prescription.
Further, the weight percent of each component is silicon carbide 40%, mullite 40%, alumina powder 20% in the described prescription.
Further, the weight percent of each component is silicon carbide 20%, mullite 50%, alumina powder 15%, silicon powder 15% in the described prescription.
Further, the weight percent of each component is silicon carbide 30%, mullite 55%, alumina powder 13%, composite additive 2% in the described prescription.
Further, the weight percent of each component is silicon carbide 35%, mullite 45%, alumina powder 10%, silicon powder 9%, composite additive 1% in the described prescription.
Further, the weight percent of each component is silicon carbide 30%, mullite 43%, alumina powder 20%, silicon powder 5%, composite additive 2% in the described prescription.
Further, the weight percent of each component is silicon carbide 30%, mullite 50%, alumina powder 14%, silicon powder 4.5%, composite additive 1.5% in the described prescription.
In spray material, add silicon carbide and mullite among the present invention, formed Al
2O
3-SiO
2The rock steady structure of-SiC, and aggregate mullite and silicon carbide and alumina powder and silicon powder proportioning be controlled at about 6.5: 3.5, make it that enough tap densities and physical strength be arranged, and reduced the rebound degree of this product, make product in use have more stability and reliability.Select tripoly phosphate sodium STPP and methylcellulose gum to form composite additive, to improve workability and use properties.
