Ultratemp-AL is an economical low density calcium silicate board that has received an additional heat treatment. The resultant prouct has minimal shrinkage after heating. Since most failures from these types of refractory boards are due to cracks (checks) developing as the result of thermal shrinkage, the low shrinkage of Ultratemp-AL makes it an ideal candidate for many molten metal contact applications such as: Transition Plates, Caster Tips, Skim Dams, Trough Dams & Components, Launder Sections, Floats, Spouts
1560 F (849 C ). It provides prolonged resistance to cracking and disintegration from thermal cycling or the action of liquid metal flow which reduces the risk of inclusions and casting contamination. The low thermal capacity and high insulating value of Ultratemp-AL ensures that low metal melting and holding temperatures are maintained, resulting in better fuel economy, reduced surface metal oxidation, and improved metal quality.
SHRINKAGEUltratemp-AL is factory heat treated to provide extremely low thermal shrinkage. The resultant board exhibits minimal thermal movement and retains dimensional stability when in direct contact with molten metal and other high temperature environments.
Ultratemp-AL board has a smooth non-porous surface, and added raw materials that prevent metal adhesion, allowing for easy removal of any frozen metal residues after cooling without damage to the components.
Ultratemp-AL can be easily machined using standard shop equipment. Normal engineering techniques and tooling will produce high definition, tight tolerance components with excellent surface finishes.
