At Oryvia Refractories, we offer Mortar Lee Set-50, an alumina-based refractory mortar developed for high-temperature refractory bonding applications. This product features a chemical/ceramic bonding system and is designed for applications where suitable bonding between refractory materials is required. With an alumina content of 45–50% and a maximum safe application temperature of 1450°C, Mortar Lee Set-50 is an industrial bonding material for appropriate refractory lining requirements.
Mortar Lee Set-50 is classified as an alumina mortar with a chemical/ceramic bond. Its fine particle structure supports the preparation of a workable mortar consistency for appropriate refractory installation applications.
Our product has a specified top grain size of 0.5 mm. The recommended water requirement for achieving trowelling consistency is 21–28%, subject to the applicable preparation and installation requirements.
The product has a specified sintering temperature of 1000°C and a maximum safe application temperature of 1450°C. These are distinct technical parameters and should be considered separately when evaluating the material for an industrial application.
Industrial Applications
Mortar Lee Set-50 is intended for suitable refractory bonding applications. Refractory mortars are generally used to form bonding joints between compatible refractory bricks and masonry components in high-temperature installations.
Potential application areas for an appropriately selected alumina refractory mortar include:
Application suitability depends on the refractory brick composition, operating temperature, furnace environment, joint design and installation conditions. We recommend confirming compatibility before selecting the mortar for a particular lining system.
Before selecting Mortar Lee Set-50, industrial buyers and refractory engineers should evaluate the following factors:
