WAM® 60 CG – Construction Grade Castable

WAM® 60 CG is a high temperature castable blending low cement and ultra low cement technology.  It is comprised primarily of a 60% alumina mullite containing aggregate. The amount of mullite contained in this aggregate is significantly more than the lower alumina containing aggregate present in the WAM® 50 CG. As a result of the increased mullite content and lower cement levels in this product; the material to be suitable for use up to 3100oF. WAM®

 

Construction Grade 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. It is an economical choice to the premium grade products when trying to match desired product lifetime to an existing maintenance schedule. It is available in several versions. The coarse version increases the material abrasion and impact resistance. There is also 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 CG finds application in several areas as a high temperature, low reactivity thermal protection material. This includes furnaces, ladles, and other furniture  for iron and steel foundries and mills, kiln car decks, annealing furnaces and bases, soaking pits, ladle lip rings, 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 as well. The TSR version has been used to cast burner blocks.
