Abstract

The invention provides a lip tile, which is prepared from the following raw materials by weight percent: 35-45% of tabular corundum, 25-35% of aluminum oxide, 10-20% of zircon sand and 15-20% of mixture, wherein the mixture comprises the following components by weight percent: 25-45% of phosphoric acid or phosphate, 10-20% of boron anhydrous, 40-60% of alpha-Al2O3 micro powder and 2-5% of calcium compound. The tabular corundum good in sudden change resistance and erosion resistance is employed as the aggregate of the lip tile; therefore, the lip tile is good in sudden change resistance and erosion resistance, long in service life, and capable of improving the quality, yield and benefit of a glass product; and the lip tile is low in cost.

Description

Lip tile
Technical field
The present invention relates to fire resisting material field, be specifically related to a kind of lip tile.
Background technology
Lip tile is as the refractory materials between domestic and international glass industry glass melter and the feeding machine, and its quality directly influences the quality and the outward appearance of glasswork.At present domestic commonly used be to adopt ramming process, the lip tile that clay saw lumber matter is produced, it is many bubble in use to occur, not anti-erosion, work-ing life is short.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of lip tile, and good plate diamond spar is done aggregate to select anti-acute degeneration and erosion-resisting characteristics for use, and its anti-sudden turn of events, corrosion-resistant property are good, and long service life can improve glassy product quality, output and benefit, and is cheap.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: lip tile, and raw materials used comprising: by weight percentage, plate diamond spar 35-45%, aluminum oxide 25-35%, zircon sand 10-20%, mixture 15-20%; Said mixture comprises: by weight percentage, and phosphoric acid or phosphoric acid salt 25-45%, boric anhydride 10-20%, α-Al 2O 3Micro mist 40-60%, calcareous compound 2-5%.
As preferably, said plate diamond spar granularity is below the 1mm.Anti-acute degeneration of the brick of processing and resistance to fouling are good.
As preferably, said aluminum oxide grain size is below the 0.5mm.The anti-acute degeneration of the brick of processing, resistance to fouling, quality are good.
As preferably, said zircon sand granularity is below the 0.1mm.The anti-acute degeneration of the brick of processing, resistance to fouling, intensity are good.
As preferably, said α-Al 2O 3Al in the micro mist 2O 3Proportion>=99.6%, true specific gravity>=3.95g/cm 3Purity is high, impurity is few, becomes the brick quality good.
As preferably, said α-Al 2O 3The micro mist powder granularity is below the 10 μ m.The quality of the brick body that makes is good.
As preferably, said lip tile adopts vacuum batch mixing, vacuum injection when batch mixing prepares.The adobe that makes is better.
As preferably, when firing, adopt said lip tile hyperthermia tunnel Kiln to fire.Fire effective, energy-conserving and environment-protective.
As preferably, said lip tile firing temperature is 1500-1650 ℃.Fire effective under this TR.
As preferably, utilize the waste heat in the hyperthermia tunnel Kiln dry during said lip tile cooling.Fast drying, energy-conserving and environment-protective.
Beneficial effect:
The lip tile that the present invention adopts technique scheme to provide, good plate diamond spar is done aggregate to select anti-acute degeneration and erosion-resisting characteristics for use, and its anti-sudden turn of events, corrosion-resistant property are good, and long service life can improve glassy product quality, output and benefit, and is cheap.
Embodiment
Embodiment one:
Lip tile, raw materials used comprising: by weight percentage, plate diamond spar 45%, aluminum oxide 25%, zircon sand 15%, mixture 15%; Said mixture comprises: by weight percentage, and phosphoric acid or phosphoric acid salt 25%, boric anhydride 10%, α-Al2O3 micro mist 60%, calcareous compound 5%.Said plate diamond spar granularity is below the 1mm.Said aluminum oxide grain size is below the 0.5mm.Said zircon sand granularity is below the 0.1mm.Al2O3 proportion >=99.6% in said α-Al2O3 micro mist, true specific gravity >=3.95g/cm3.Said α-Al2O3 micro mist powder granularity is below the 10 μ m.Said lip tile adopts vacuum batch mixing, vacuum injection when batch mixing prepares.When firing, adopt said lip tile hyperthermia tunnel Kiln to fire.Said lip tile firing temperature is 1650 ℃.Said lip tile utilizes the waste heat cooling in the hyperthermia tunnel Kiln when cooling off.
During production; Earlier by than part respectively with plate diamond spar be crushed to that granularity is below the 1mm, aluminum oxide powder is broken to that granularity is below the 0.5mm, to be broken to granularity be below the 0.1mm to zircon flour; Then the three is mixed, and then mix with mixture, slip casting processes the brick body, go into tunnel again after the drying and fire.
