Forehearths TRIZ Cases
- Transfer Pipe Movable Flange Design for Pre-Heating Thermal Expansion
See how a movable flange support allows transfer pipe thermal expansion during pre-heating, red
- Glass-Ceramic Composition With Compressive Layer for Crack Resistance
Controlled crystallization and ion exchange improve crack resistance, drop performance, fracture toughness, and low-haze transparency.
- Forehearth Fluorescent Glass Frits for Uniform Rare-Earth Dispersion
Rare-earth glass frits added in the forehearth create uniform fluorescent glass at lower loading across multiple glass types and effects.
- Stilling Tank and Feeding Spout for Stable Molten Glass Flow
A stilling chamber with non-submerged burners and a feeding spout calms foamy molten glass and delivers a stable downstream feed.
- Joule-Heated Glass Conduit Structure to Prevent Devitrification
Localized insulation and a concave heating member keep molten glass above liquidus temperature at the conduit exit, preventing devitrification.
- Electrical Flange Support Assembly for Thermal Expansion Isolation
A movable bracket and insulated bracing support heavy electrical flanges while accommodating vessel thermal expansion and preventing misalignment.
- Glass Feeder Channel Heating With Slim Flames for Uniform Melt Temperature
Alternating fuel and oxidant lances create slim, non-contacting flames that heat glass melt uniformly while reducing wall load, heat loss, and NOx.
- Molten Glass Agitation Structure With 360° Flow Balancing
Multi-point 360° molten glass flow balances agitator forces, reduces oscillation, and improves homogenization at high flow rates.
- Glass Transport Leak Mitigation Using Silica Viscosity Barriers
Silica-containing barriers raise leaked molten glass viscosity to slow or stop flow, protecting insulation and reducing rebuild risk.
- Molten Glass Delivery Rail Carriage for Thermal Expansion Relief
Angled rails and grooved rollers let the molten glass delivery carriage absorb conduit expansion, cutting thermal stress and extending component life.
