Low Cement Castables (LC)

All Low Cement Castables produced by Westmoreland Advanced Materials, LLC are based on the latest surfactant and bonding matrix technology. These premium products are designed to flow exceedingly well at low moisture contents making them ideal to pump and shotcrete in addition to vibration cast. This group of castables is represented by a broad range of products with service temperatures up to 3,400oF in a variety of service environments.

 

Alumina Based - Low Cement Castable Systems

As  with most of the  products produced by Westmoreland Advanced Materials, LLC these castables are available with an aluminum penetration resistance package for use in contact with molten aluminum metal. These compositions are designated with the AL prefix. These products are also available with a very coarse aggregate. Compositions utilizing the coarse aggregate are very resistant to impact an abrasion and are successfully employed in floors, jambs and lip rings and other applications. These compositions are designated with a C postscript. A fine version is also available for use in making highly detailed cast shapes and are designated with an F postscript. Alkali resistant additives are available and are designated with an AR postscript. Finally we offer Thermal Shock Resistant packages for use in applications such as burner block or other thermally cycling environments. These products are designated with a TSR postscript.

Available Alumina Based Variations:

 WAM® 50 LC    WAM® 60 LC    WAM® 70 LC    WAM® 80 LC    WAM® 93 LC    WAM® 98 LC

 

Silicon Carbide Based - Low Cement Castable Systems

These Low Cement Castables are premium products based on the latest surfactant and bonding matrix technology. They are designed to flow exceedingly well at low moisture contents making them ideal to pump and shotcrete in addition to vibration cast. This group of castables is represented by a broad range of products with service temperatures up to 3300oF in a variety of service environments. (note: SiC will oxidize above 2500oF)

 

These products contain Silicon Carbide. Silicon carbide provides a very high degree of abrasion resistance. These products find applications where solid materials are pushed on or across the cast surface. For example sows being sweated on a hearth of an aluminum melting furnace. They are also used in application where molten metal streams impact refractory.

 

As  with most of our products these are available with an aluminum penetration resistance package for use in contact with molten aluminum metal. These compositions are designated with the AL prefix. These products are also available with a very coarse aggregate. Compositions utilizing the coarse aggregate are very resistant to impact an abrasion and are successfully employed in floors, jambs and lip rings to name a few applications. These compositions are designated with a C postscript. We offer a Fine version for use in making highly detailed cast shapes. These are designated with an F postscript.

Spinel Bonded - Low Cement Castable Systems

WAM® 20 SP LC is a low cement castable which also contains preformed spinel and is suitable for use up to 3300oF. The elongated structure of spinel combined with its thermal behavior make it ideal for use in thermally cyclic environments. The orientation of the mineral provides for excellent impact resistance and overall strength. Spinel is also resistant to chemical attack by many common slags particular to the steel industry.

 

WAM® 20 SP LC finds application in several areas related to steel production.  This includes most areas within a ladle. It also has application as precast parts for use in the ladle such as impact pads. It is available in a coarse version which increases the material abrasion and impact resistance.

Available Spinel Bonded Variations:

 WAM® 20 SP LC
Silica Based - Low Cement Castable Systems

Low Cement, Silica Based Castables produced by Westmoreland Advanced Materials, LLC are premium products based on the latest surfactant and bonding matrix technology. They are designed to flow exceedingly well at low moisture contents making them ideal to pump and shotcrete in addition to vibration cast. This group of castables is represented by products with service temperatures up to 2000oF.

 

These products are based on vitreous silica. A typical application area is in aluminum troughing and related transfer vessels. These products tend to have lower thermal conductivity and expansion compared to their alumina or silicon carbide based counter parts.

 

A Fine version (designated with an F postscript)  is available for use in making highly detailed cast shapes.

 Available Silica Based Variations:

 WAM® 80 VS LC
