WAM® 80 LC – Alumina Based Low Cement Castable

WAM® 80 LC is a high temperature, low cement, castable comprised primarily of a 80% alumina bauxite containing aggregate. The bauxite content and lower cement levels in this product permit the material to be suitable for use up to 2,900oF. Bauxite is a high temperature aggregate that does not contain mullite, but has a larger amount of accessory oxides compared to the mullite aggregates. As such it is more susceptible to chemical reactions at elevated temperatures. However, since bauxite is a naturally fused mineral it is very hard and thus abrasion and impact resistant.

 

Westmoreland Advanced Materials, LLC low cement castable compositions incorporate the latest available technology in regards to particle size distribution, surfactants, and in-situ reactants that promote volume stability at temperature, density, non-reactivity, water demand, working time and placement characteristics. You will not find a superior product in the market place. It is available in several versions. The coarse version increases the material abrasion and impact resistance. Packagesare made available for aluminum penetration resistance, alkali resistance, and thermal shock resistance. A fine package is also available for patching and  intricate precast shapes.

 

WAM® 80 LC finds application in several areas as a high temperature, thermal protection material. This material is commonly used in areas that undergo increased amount of abrasion and impact. This includes Delta sections, furnaces, ladles, and other furniture  for iron and steel foundries and mills. It has been used in copper furnaces and a variety of rotary kiln areas and precast impact pads or similar shapes.
