High density Calciumsilikatplatte engineered für direct contact with molten aluminum. Neinn-wetting surface, superioder machinability, excellent dimensional stability — ideal für launders, floats, spouts, transition plates, and holding furnace linings.
The aluminum industry operates with molten metal at temperatures exceeding 700°C, requiring materials that are non-wetting, chemically stable, and mechanically strong. Traditional refractories often fail due to aluminum penetration, oxidation, oder mechanical wear.
HR RHINO high density Calciumsilikatplatten are specifically engineered für direct molten aluminum contact, with densities ranging from 800-1200 kg/m³ and options für glass fiber oder carbon fiber Verstärkung. Based on high-purity Xonotlit, our boards resist aluminum penetration while maintaining structural integrity under extreme conditions.
Wichtige Leistung advantages include non-wetting with molten aluminum, excellent machinability für complex shapes (floats, spouts, transition plates), dimensional stability, and long service life — making our boards the preferred choice für aluminum smelters, die casters, and continuous casting operations worldwide.
Sechs kritische Anwendungen in der aluminum production and casting process where HR RHINO high density Calciumsilikatplatten liefern superioder Leistung.
Launder systems that transport molten aluminum between furnaces and casting stations require non-wetting, thermally stable linings. Our high density boards resist aluminum penetration and maintain smooth metal flow with minimal heat loss.
Continuous casting and sheet casting operations rely on precision-machined floats, spouts, and casting tips. Our CNC-machinable high density boards can be shaped into complex geometries with tight Toleranzs.
Billet and ingot casting systems use transition plates and hot-top rings in direct contact with molten aluminum. Our products provide thermal gradient control and prevent premature solidification at critical transition points.
Holding furnaces maintain molten aluminum at precise temperatures before casting. Our boards serve as hotface linings, dams, and launders, providing both thermal insulation and resistance to aluminum attack.
LPDC systems use sprue bushes, riser tubes, nozzles, and feeder box liners. Our carbon fiber verstärkt 800 kg/m³ grade offers ausgezeichnete thermische shock resistance für repeated casting cycles.
Our high density boards are machined into collars, gaskets, and pipe Support rings used throughout the aluminum plant für sealing, insulation, and structural separation between hot and cold zones.
Engineered Leistung für direct molten aluminum contact applications.
Molten aluminum does not wet oder bond to the board surface, preventing buildup, contamination, and thermal bridging.
CNC machinable to tight Toleranzs. Complex shapes like floats, spouts, and custom casting components produced easily.
