QuikBuild™ refractories are special flour blends that are designed to enhance the performance of Remasol® QuikBuild.
The wide particle size distribution of the QuikBuild refractories maximises the benefits of a QuikBuild slurry creating thicker shell layers.
It is available in two types:
• QuikBuild F – Fused Silica
• QuikBuild A – Aluminosilicate
Aluminosilicate Refractory Flour & Sand
REMASIL® is the trade name for REMET®’s Aluminosilicate products. REMASIL 50 is calcined to a constant weight and ground to specific grade of both grains and flours. These products produce investment casting shells of excellent refractoriness and high temperature stability, at an incredibly economical rate. The REMASIL 50 range provides increased strength when compared to Fused Silica systems.
In the case of stucco grains, the custom grinding of REMASIL results in a more uniform product which has a narrow range of particle sizes and a minimum amount of fines (dust). Reduced fines improve both permeability and intercoat adhesion. Whilst the powder grains can offer the user a greater level of flexibility, through its offering in two separate cuts, allowing a foundryman to choose the specific grade that best suits their needs.
REMASIL 50 Benefits
- Increased hot strength.
- Robust and resilient.
- Easy knockout.
Available in the following grades:
REMET® LHT Fused Silica
REMET® LHT Fused Silica is made from pure, natural white silica rich sand at 1980oC. At this temperature, the crystalline quartz melts and becomes non-crystalline. The resulting refractory is a pure material that is readily available, which provides a long life slurry practical for both ferrous and non-ferrous metal casting.
REMET LHT Fused Silica has excellent thermal characteristics, as it exhibits a very low level of thermal expansion (5.0 x 10-7 cm/cmoC). Whilst it also provides low thermal conductivity, together these attributes provide a refractory with excellent thermal shock resistance.
This product provides for excellent slurry stability as well as good pH stability, when used in the primary coating. This will aid in preventing the solution from dropping out, which is crucial in achieving an even coat application, essential in avoiding surface defects.
The shell produced using REMET LHT Fused Silica, is both light weight and highly permeable. Whilst the refractories unique behaviour under extreme heat, creates a shell that once cooled, allows for an easier knockout.
This material is offered in a wide variety of powder and grain sizes, for both primary and secondary coat slurry applications.
REMET LHT Fused Silica is available in the following grades:
- RP2 (120 mesh)
- RP1 (200 mesh)
- RG3 (50/100)
- RG2 (20/50)
- RG1 (10/20)
