Abstract
The invention relates to a refractory castable with combination of hercynite and refractory fibers. The refractory castable with combination of hercynite and the refractory fibers is prepared from the following raw materials: iron scales, graphite, zirconium oxide hollow balls, alumina micro powder, carbon nanofiber powder and fireproof steel fibers, wherein the fireproof steel fibers and zirconium oxide hollow balls are taken as aggregates and the carbon nanofiber powder, iron scales, graphite and alumina micro powder are taken as powder. The refractory castable with combination of hercynite and the refractory fibers is prepared from the following raw materials in parts by weight: 30-40 parts of iron scales, 20-25 parts of graphite, 20-30 parts of zirconium oxide hollow balls, 10-20 parts of fireproof steel fibers, 40-45 parts of alumina micro powder and 5-10 parts of carbon nanofiber powder.
Description
Technical field
The invention belongs to technical field of refractory materials, particularly relate to a kind of refractory castable of hercynite combined fire resistant fiber.
Background technology
Compared with qualitative refractory product, with refractory castable be that the unshape refractory of representative has that technical process is short, production energy consumption and cost is low, easy to use, applied widely, globality and the advantage such as result of use is good, thus worldwide obtain and develop rapidly, its proportion shared in whole refractory materials is more and more higher.In the country of some refractory technologies advanced person, the output of unshape refractory is close to the output even having exceeded setting goods.Such as, the ratio that current Japanese unshape refractory output accounts for whole refractory materials reaches about 60%; The U.S. be about 50%; English, moral, Fa Deng state are 40% ~ 50%.Nowadays, refractory castable has been widely used in the high temperature service of the industrial circles such as metallurgy, building materials, electric power, chemical industry, such as, in quality coal in cement kiln systems, has now widely applied the refractory castable of various material.
In new type dry kiln, decomposing furnace tapering, settling chamber, kiln tail slope etc., because thermal load is high, stand the chilling impact that fault stops kiln, these positions mould material used has higher heat resistance and good alkali resistance, wear resistance and thermal shock resistance simultaneously, comparatively normal these positions used be steel fiber castable or High-Alumina Low Cement Castable, due to these local easily putties, through air bubble, the hydraulic giant even impact of iron staff, very serious to the damage of mould material, often stop kiln maintenance.
Summary of the invention
In view of this, for the deficiencies in the prior art, the invention provides and a kind ofly form stable kliner coating in furnace lining inside to improve the refractory castable of the hercynite combined fire resistant fiber in refractory castable work-ing life.
A kind of refractory castable of hercynite combined fire resistant fiber, be made up of following raw material: iron scale, graphite, Bubble zirconia, alumina powder, carbon nanofiber powder, fire-resistant steel flat flanges, wherein, fire-resistant steel flat flanges, Bubble zirconia are aggregate, and carbon nanofiber powder, iron scale, graphite, alumina powder are powder; The parts by weight of above-mentioned raw materials are: iron scale 30 ~ 40 parts, 20 ~ 25 parts, graphite, Bubble zirconia 20 ~ 30 parts, fire-resistant steel flat flanges 10 ~ 20 parts, alumina powder 40 ~ 45 parts, 5 ~ 10 parts, carbon nanofiber powder.
In sum, the present invention compared with prior art, Bubble zirconia in aggregate has special surface tissue and boring, surface irregularity, and under the effect of carbon nanofiber powder, increase contact gear ratio surface-area, aggregate alumina powder in powder is made to be combined firmly, both improve fire performance, turn increase intensity and the heat insulation effect of material, hercynite is generated in the reducing atmosphere that simultaneously iron scale and alumina powder are formed at graphite, hercynite and Bubble zirconia, fire-resistant steel flat flanges is combined closely and is formed stable kliner coating in furnace lining inside.
