Description
Technical field
The present invention relates to a kind of corundum fireproof coating, a kind of corundum light-weight refractory coating.
Background technology
High temperature kiln furnace lining is commonly used alumina hollow ball material and is built working lining by laying bricks or stones, reaches the most high temperature resistant but also insulation, can realize again heat resistanceheat resistant simultaneously and peel off, but it is expensive disposable and maintenance replacing puts into the biggest.Alumina hollow ball belongs to lightweight refracrory, its intensity is not so good as compact refractory material, the most in use, alumina hollow ball refractory lining is often clashed into by the product burnt on external blow such as kiln car or kiln car and ftractures, falls block, causes kiln heat radiation aggravation to be affected kiln sintering effect.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides one to smear conveniently, and agglutinating property is good, curing time is short, the fire-resistant coating that can be rapidly roasted and use, and this material outstanding feature is exactly that application property is good, smear and facilitate agglutinating property good, and curing time is short, can be rapidly roasted and use.At high temperature, this coating can be together with old lining sintering, and bond strength is high, difficult drop-off.
The present invention solves that the technical scheme that above-mentioned technical problem is used is: a kind of corundum fireproof coating, it is characterized in that it includes the component of following parts by weight: 3-1mm mullite aggregate 30-40 part, 1-0mm alumina hollow ball 5-15 part, 0.5-0mm alumina hollow ball 10-20 part, mullite powder 11-21 part, modified Faku County soil 4-6 part, aluminate cement 5-7 part, mullite 1-5 μm whisker 1-3 part, titanium nitride 1-5 μm whisker 1-3 part, additive 3-5 part, the additional Alumina gel accounting for above-mentioned gross weight 10-18%；Additive is magnesium sulfate calcium potassium powder, silicon powder and carbonic acid zirconium powder, and its weight ratio is 1:1:1, the density of Alumina gel be 1.1g/mL, pH be 4.5.
In above-mentioned dispensing, described Alumina gel such as can be replaced at the Ludox of weight.
The aluminum content of described aluminate cement is more than 50%.
Described modified Faku County soil first step is that after Faku County's soil is incubated 10 hours at 700 DEG C, acquisition product 1 is then uniform with polyvinyl alcohol product 1 by weight 50:1, is modification Faku County native.
Beneficial effect: one corundum fireproof coating of the present invention, has and has good workability, and easy to apply, agglutinating property is good, and curing time is short, can be rapidly roasted and use.After high-temperature heat treatment, this coating can together with old lining sintering, and intensity height, good thermal shock, the most easy to crack, repair efficiency are good, be greatly improved the service life of high temperature kiln, after a maintenance, service life improves more than 30%.
Detailed description of the invention
For making the technical problem to be solved, technical scheme, the technique effect of acquirement taked should be readily appreciated that the present invention is further illustrated in conjunction with embodiment.
