WAM® 60 ULC – Ultra Low Cement Castable

WAM® 60 ULC is a high temperature, ultra-low cement containing castable.  It is comprised primarily of a 60% alumina mullite containing aggregate. As a result of the increased mullite content and the very low cement levels in this product; the material is suitable for use up to 3100oF. In addition to the higher temperature limits the product is less susceptible to chemical attack and has higher hot strengths compared to its low cement counterpart.

 

Westmoreland Advanced Material LLC’s  ultra-low cement castable technology incorporates 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.

 

Several versions of these ultra-low cement castables are available including a coarse mix that  increases the material’s resistance to both abrasion and impact. Also available are add on packages for aluminum penetration resistance, alkali resistance, and thermal shock resistance. A fine package is available for patching and  intricate precast shapes.

 

WAM® 60 ULC finds utilization in several areas as a high temperature, low reactivity thermal protection material. Furnaces, ladles, and other furniture  for iron and steel foundries and mills, kiln car decks, annealing furnaces and bases, soaking pits and ladle lip rings are typical applications. The AL version has been used in all aluminum processing and transport vessels. It has been used in a variety of rotary kiln and hearth furnace applications while the TSR version has been used to cast burner blocks.
