AZS REFRACTORY PDF

Fused Cast AZS block is also called electro Zircon corundum block, which is abbreviated as AZS because it contains Al2O3-ZrO2-SiO2. Alumina-zirconia-silica (AZS) fused-cast refractories began to increase in popularity in glass furnace applications for the glass contact and. fused Cast AZS refractories are the most widely used materials both in glass contact and superstructure of glass melting products are made of.

Thus, the pencils prepared from the composition of Example 1 were surprisingly resistant to corrosion. Ceramic powder compositions and azw device substrates utilizing the same.

Development of AZS refractories for the glass industry|INIS

Glass melting furnaces include pot furnaces, glass tanks, tank furnaces, and the like. The fingers were dipped into molten refractpry at a high temperature. It is the most widely used in the products of glass furnace, the upper part of the structure is mainly applicable to the molten pool, pool wall brick and tile work pool, material etc.

The refractory blocks usually receive considerable wear from the molten glass and the charging of glass making materials. The cross sectional area of the pencil lost refrxctory the test was measured and the results were averaged. Thus, the colloidal silica refractories disclosed herein show superior resistance under harsh conditions compared to a refractkry art refractory.

The refractory composition has been found to provide excellent corrosion resistance.

The method of claim 21 wherein the furnace is a glass furnace. Get permanent URL for this record.

It is known that particle size effects the properties of the liquid refractory compositions such as pumpabilityas well as the mechanical and chemical properties of the final refractory.

Green member for the manufacture of a sintered refractory product having improved bubble generating behavior. Mainly used in glass furnaces, they can withstand aggressive conditions in contact with molten glass. Proper particle provides good particle packing zzs reduced porosity, which leads to greater strength and less glass penetration in the refractory.

The refractory blocks can become deeply scored and may develop wear spots or portions where the molten glass has eroded or dissolved the refractory. Fused-cast-alumina-zirconia-silica refractory, methods of making it and glass melting furnace employing it. Year of fee payment: The mechanical rferactory from the frame and outer blocks holds the blocks together. The refractory composition of claim 1 wherein the first set of components comprises alumina particles with an average particle size greater than 1 mm.

Other proportions of the first refracttory of components may be used.

The refractory composition may be cast into blocks for subsequent use in a glass tank or other furnace, or may as formed directly onto the wear portion of a glass tank or other furnace. The various components are available from AluChem, Inc. Refractory materials that include cement tend to be difficult to dry when setting, especially at lower temperatures.

More particularly, this invention relates to colloidal silica refractories for the lining of furnaces, such refractorj glass and brass furnaces. Please provide a name for this query: Fused AZS particles consist of particles each comprising alumina, zirconia, and silica.

Brass scrap is collected and transported to the foundry where it is melted in the furnace and recast into billets. The refractory composition may be formed on one or more portions of the sidewall or hearth. Reference Number Reference Number.

Therefore, the invention is not limited to the specific details, representative embodiments, and illustrated examples in this description. Publication Year Publication Year.

Properties and applications of fused cast AZS

The furnace is also used to heat up billets azss the brass into the right form and size. The test was repeated for each sample for a total of two tests for each composition. Fused cast AZS36 brick due to the increase in chain like zirconia more crystals, and glass phase content is relatively low, so the 36 fused zirconia corundum brick corrosion resistance has been further enhanced.

The colloidal silica refractory provides surprisingly good resistance to high temperature corrosive environments. So suitable for glass liquid velocity faster or high temperature region. Glass may be constructed of separate refractory brick or blocks within a frame.

Hollow piece for producing a sintered refractory product exhibiting improved bubbling behaviour. The results obtained indicate that the composition with low content of ZrO 2 can provide better properties than the commercial product, with some modifications in the particle size distribution.

The first set of components includes alumina and zirconia. Refractory compositions containing monoclinic zirconia and articles formed from these compositions exhibiting improved mechanical strength at high temperatures and improved resistance to thermal shocks. Dense microstructure of Fused Cast AZS 33 bricks to glass corrosion resistant performance is good, not easy to produce slag and other defects in glass kiln.

The particle size of the refractory material allows for a multi-functional material which can be easy shotcreted, pumped or cast. The first set of components also may include a flow modifier to enhance or alter the flow properties for forming the colloidal silica refractory prior to setting. The median particle size of the first set of components may be greater than 40 microns. In another aspect, a method of preparing a refractory includes providing a first set of components and a colloidal silica binder.
