WAM® 60-24 LW – Standard Lightweight Castable

WAM® 60-24 LW is a lightweight castable with approximately a 60 pound per cubic foot density and a 2400oF maximum operating temperature limit. In general the lower the density the greater the insulating capability of the material.

 

Lightweight castables are primarily used as insulating backup linings. However, they can be used as working linings in non contact areas such as roofs. In some cases it is appropriate to use lightweights in contact areas but one should discuss the specific application with your technical sales representative to determine if appropriate for the specific product and the contact material.

 

Depending on your specific thermal and contact needs your WAM® representative will recommend a combination of insulating backup materials and hot face or working lining materials to fit your needs. Design of furnace lining configurations to achieve energy usage goals is an area we excel, particularly in aluminum contact applications.  We use a proprietary thermal program to ensure proper shell temperatures, freeze plan locations and energy savings for your process.
