Incomplete Hydrogen Removal? Upgraded Si₃N₄ Rotor Systems Enhance Casting Quality and Process Stability

2025-02-02
Latest company news about Incomplete Hydrogen Removal? Upgraded Si₃N₄ Rotor Systems Enhance Casting Quality and Process Stability

In aluminum die-casting operations, degassing efficiency directly determines casting integrity. Conventional graphite rotors oxidize and erode quickly, creating uneven gas dispersion and frequent maintenance.
The Silicon Nitride Ceramic Rotor System utilizes a precision-engineered impeller design with optimized bubble diffusion channels to maximize hydrogen removal.

Constructed from dense Si₃N₄, it resists thermal shock and corrosion even during 1,000-hour continuous runs at 900–1000 °C.
The result is a 30–40 % reduction in hydrogen content, 8–10 % increase in metal density, and a significant drop in pinhole defects.
Because the ceramic is chemically inert to molten aluminum, it ensures a cleaner melt, extending filter life and improving downstream quality.

For automotive wheels, pistons, and structural die-cast parts, the upgraded Si₃N₄ rotor system delivers higher yield, lower maintenance, and superior consistency—helping manufacturers achieve lightweight, defect-free aluminum components for demanding markets.
