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.

Properties and applications of fused cast AZS

Unwrought refractory composition, in particular for producing glass furnace hearths. Therefore, selected key parts of the glass furnace, so that these parts of the life and the other part of the lower scale. 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 pencil prepared from the formula of Example 1 lost only an average of To simulate the harsh conditions in a glass melting furnace, refractory corrosion tests were performed to evaluate resistance to sodium hexametaphosphate.

Article made from refractory material for contact with a liquid metal or alloy, a method for manufacture, use and method of use of same. The first set of components may include other compounds such as a setting agent. The method of claim 21 wherein the first set of components comprises alumina particles with an average particle size greater than 1 mm.

The glass-making materials usually include a mixture of cullet and batch materials. The refractory composition has been found to provide excellent corrosion resistance.

The zirconia may be provided by zircon flour or a zirconia bearing material. Development of AZS refractories for the glass industry. The furnace was operated for a period of time and the composition was found to perform well throughout the furnace. 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. To simulate the harsh conditions in a glass melting furnace, refractory corrosion tests were performed on the colloidal silica refractories to evaluate their resistance to molten glass.

Fused Cast AZS Refractories ~ LONTTO Refractory

The refractory composition of claim 1 wherein the refractory composition is formed on at least one wear portion of a glass melting furnace. Xzs AZS refractory blocks are made from molten material cast into molds, which are machined after hardening.

The colloidal silica binder holds or binds the first set of components together in a monolithic form. Reading, OhioAlcan, Inc.


After the test, the samples were analyzed to determine the resistance of the refractory composition to the harsh conditions.

Mainly used in glass furnaces, they can withstand aggressive conditions in contact with molten glass. EP EPB1 en The present invention provides a colloidal silica refractory composition that is especially rrefractory for glass melting furnaces.

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 may contain no erfractory.

Montreal, Canadaand other conventional suppliers. A refractory composition comprising: Hollow piece for producing a sintered refractory product exhibiting improved bubbling behaviour.

The alumina may be reactive or calcined. In one refractlry, the colloidal silica may have an average particle diameter in the range of about 4 nm through about nm. Brass scrap is collected and transported to the foundry where it is melted in the furnace and recast into billets.
