Abstract

The present invention relates to fire-retardant concrete and a prefabricated component thereof, wherein the prefabricated component is mainly used for the kiln walls of ceramic tunnel kilns. The fire-retardant concrete is composed of aluminum-silicon aggregate, aluminum-silicon powder, aluminate cement and additives, wherein the additives are a naphthalene high-efficiency water reducing agent, rosin salts and polyphosphate; the fineness of the powder is less than 0.08mm. The prefabricated component for the kiln walls, which is produced by the concrete, is in a hollow type, and a heat-insulation material can be filled in the prefabricated component. The concrete of the present invention has the advantages of good strength after being burnt at intermediate temperature, good heat shock performance and low heat-conduction coefficient, and the prefabricated component used for building the kiln walls has the advantages of labor and time saving and good heat-insulation effect.

Description

Fire-retardant concrete for porcelain tunnel kiln wall
The present invention relates to a kind of refractory concrete.
At present, the porcelain tunnel kiln wall working lining mainly adopts refractory brick such as high alumina brick, clay brick to build by laying bricks or stones, and heat shield liner mainly adopts insulating brick to build by laying bricks or stones, take a lot of work, time-consuming, and effect of heat insulation is also not ideal enough.Build the kiln wall by laying bricks or stones if make the assembling of hollow assembled kiln wall prefabricated component with refractory concrete, then have effect preferably, this refractory concrete is particularly suitable for building by laying bricks or stones of the energy-conservation tunnel kiln wall of wide section.
The objective of the invention is to develop a kind of refractory concrete and prefabricated component thereof, make it under prerequisite, have thermal shock resistance and lower thermal conductivity preferably simultaneously with higher intensity.
Refractory concrete of the present invention is made into by aggregate, powder, wedding agent and compound additive, wherein aggregate is a silica-aluminum materials, and the same aggregate of the material of powder, wedding agent are aluminate cement, compound additive is for mixing outward, is composited by naphthalene series high-efficiency water-reducing agent and abietate and poly-phosphate.The prescription of described refractory concrete is:
Sal aggregate 65～85%
Sal powder 5～10%
Aluminate cement 5～25%
Naphthalene series high-efficiency water-reducing agent (adding) 0.2～0.5%
Abietate (adding) 0.003～0.005%
Poly-phosphate (adding) 0.1～0.3%
Wherein aggregate can be mullite, bauxite clinker (Al 2O 3Content is 65～90%) or flint clay grog (Al 2O 3Content is 40～48%), the fineness＜0.08mm of powder, aluminate cement can be pure calcium aluminate cement or high-alumina cement.
Prefabricated component is made hollow type when making the porcelain tunnel kiln wall prefabricated component with above-mentioned refractory concrete, but the good filamentary materials of heat-proof quality such as its hollow part filling ceramic wool, and the heat radiation of kiln wall is very low when making its assembling build use by laying bricks or stones.
Earlier with powder, wedding agent and compound additive are mixed thoroughly when preparing refractory concrete of the present invention, add aggregate again and fully mix thoroughly and get final product.Prefabricated component can adopt the vibrating casting method to make.
Utilize the present invention can make the kiln wall of different sites in the wide section energy-saving ceramic tunnel furnace.For the kiln wall prefabricated component of making the band burner, its prescription is prescription one: fused mullite 77% fused mullite powder 5% pure calcium aluminate cement (Al 2O 3Content is 70%) 18% naphthalene series high-efficiency water-reducing agent, 0.2% abietate, 0.003% poly-phosphate 0.1%
For making clinkering zone kiln wall prefabricated component, its prescription is prescription two: bauxite clinker (Al 2O 3Content is 70%) 75% bauxite clinker powder, 7% pure calcium aluminate cement (Al 2O 3Content is 70%) 18%
Compound additive kind and consumption are with prescription one
For the kiln wall prefabricated component of making other each band in the kiln, its prescription is prescription three: flint clay grog (Al 2O 3Content is 45%) 76% flint clay grog powder, 6% high-alumina cement 18%
Compound additive kind and consumption are with prescription one
Material property by the said ratio preparation sees the following form
Figure C9510121300051
Prefabricated component of the present invention can connect by high temperature steel with the outside steelframe of kiln, prevents hyperthermia stress-strain and the damage and the slump that cause, prolongs its work-ing life.
Refractory concrete of the present invention is compared with general refractory castable has higher middle temperature burning back intensity, also have thermal shock resistance and lower thermal conductivity preferably simultaneously, being used to make the porcelain tunnel kiln wall prefabricated component compares with brick kiln wall, the saving of labor, save time, but and because prefabricated component hollow, can utilize fibrous insulating material more conveniently, make the heat-proof quality of kiln wall better.The present invention is specially adapted to wide section energy-saving ceramic tunnel furnace.
