Molybdenum plate

tuberod

Overview
In glass melt tanks, refractory bricks are exposed directly to the aggressive glass melt, causing corrosion, abrasion and erosion that reduce tank service life and can impair glass flow and final glass quality.

Advantages

• Highest purity for bubble-free operation (Mo ≥ 99.97% guaranteed)
• Excellent corrosion resistance against glass melts
• High creep resistance for long-term high-temperature service
• Oxidation protection via Sibor® coating
• Customer-specific solutions with in-house design and manufacturing

Typical components

• Sibor®-coated molybdenum tank reinforcements to protect ceramic stones (throat, doghouse, crosswall, bubbler, etc.)
• Molybdenum profiles for reinforcing ceramic parts
• Sintered flow and outlet pipes
• Floor drains and gutters made of molybdenum

Sibor® coating — oxidation protection
Sibor® is a hard, dense SiO2-based diffusion barrier developed to protect molybdenum during heating. The coating prevents oxidation up to approximately 1700 °C (3092 °F) and can extend protection life up to ~5000 h depending on operating temperature.

Customization and engineering
Plansee adapts reinforcement designs to each tank and manufactures components to tight tolerances. Experienced furnace engineers support design, engineering and implementation to ensure correct fit and function.
