Abstract
The invention relates to a corundum fireproof coating, in particular to a corundum lightweight and fireproof coating. The corundum fireproof coating is composed of, by weight, 30-40 parts of mullite aggregate of 2-1mm, 5-15 parts of alumina hollow ball of 1-0mm, 10-20 parts of alumina hollow ball of 0.5-0mm, 11-21 parts of mulltie powder, 4-6 parts of modified faku soil, 5-7 parts of aluminate cement, 1-3 parts of mullite of 1-5um, 1-3 parts of titanium nitride 1-5um crystal whisker, 3-5 parts of additive and aluminum sol accounting for 10-18% of total weight of the above components. The mullite fireproof coating is high in coating performance and sinterability and short in maintenance time and can be quickly put into firing and using. After going through high-temperature thermal treatment, the coating can be sintered together with furnace lining and is high in strength and thermal shock resistance, less prone to cracking, good in repairing effect and capable of effectively prolonging service life of a high-temperature furnace.
Description
Technical field
The present invention relates to a kind of corundum fireproof coating, specifically 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 not only high temperature resistant but also heat insulating, can realize again heat resistanceheat resistant simultaneously and peel off, but it is expensive, and disposable and maintain and replace drops into very large.Alumina hollow ball belongs to lightweight refractory, its intensity is not as compact refractory material, and therefore in use, alumina hollow ball refractory lining often ftractures by the product that external blow such as kiln car or kiln car burn clashes into, falls block, cause kiln to dispel the heat to aggravate, affect kiln sintering effect.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides one and smear conveniently, coking property is good, and curing time is short, the fire-resistant coating that can drop into baking fast and use, this material outstanding feature is exactly that application property is good, smears conveniently, coking property is good, and curing time is short, can drop into baking fast and use.At high temperature, this coating can together with old lining sintering, and bonding strength is high, difficult drop-off.
The present invention for solving the problems of the technologies described above adopted technical scheme is: a kind of corundum fireproof coating, it is characterized in that it comprises 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, modification 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 is 1.1g/ml, PH is 4.5.
In above-mentioned batching, described Alumina gel such as to can be replaced at the silicon sol of weight.
The aluminium content of described aluminate cement is more than 50%.
Described modification Faku County soil the first step is that Faku County's soil is obtained product 1 700 DEG C of insulations after 10 hours, then by weight 50:1, product 1 is mixed evenly with polyvinyl alcohol, is modification Faku County soil.
Beneficial effect: a kind of corundum fireproof coating of the present invention, have and have good workability, easy to apply, coking property is good, and curing time is short, can drop into baking fast and use.After high-temperature heat treatment, this coating can together with old lining sintering, and intensity is high, good thermal shock, not easy to crack, and repair efficiency is good, and greatly can improve the work-ing life of high temperature kiln, after a maintenance, work-ing life improves more than 30%.
