Shuttle Kilns, also for Glazing Crucibles for the Solar Industry

When cooling, decorating, glazing or sintering special glass during production, bogie hearth furnaces
offer numerous advantages. Due to their very good temperature uniformity, these models are perfectly
suited for burning in a separation layer of silicon nitride in crucibles for the solar industry. The bogie can
be charged outside the kiln. The shuttle can be loaded outside the furnace. Several shuttles can be used,
so that one shuttle can be charged while the other shuttle is in the kiln.

• Tmax 900 °C, 1280 °C, 1340 or 1400 °C
• Double-walled housing with rear ventilation, provides low shell temperatures
• Swing door hinged on the right side
• Heating from five sides (four sides and bogie) provides for a uniform temperature distribution
• Automatic power connection to the bogie when moved into the furnace
• Heating elements mounted on support tubes provide for free radiation and long service life
• Floor heating protected by SiC tiles on the bogie providing level stacking surface
• Multi-layer insulation consisting of lightweight refractory bricks backed by microporus silica insulation
• Self-supporting roof arch
• Freely moving shuttle with rubber tires
• Adjustable air inlet damper
• Manual vapor vent on the furnace roof

• Customized dimensions
• Additional shuttles
• Second door instead of back wall for charging from both sides
• Electro-hydraulic lift door
• Rail operation for heavy loads
• Electrical shuttle drive
• Controlled cooling system: the preset cooling curve is carried out exactly via a variable speed fan
• Automatically driven vapour vent flaps
• Heat protection shuttle to minimize heat loss when the charged shuttle has left the kiln
• Multi-zone temperature control for optimal temperature uniformity
• Fully automatic process control and documentation
• Load weights up to 50 tons
• Furnace in HDB design featuring fresh air pre-heating, exhaust gas ventilation and an extensive safety
• package for debinding and sintering in one process, i. e. without transfering the
• material from the debinding furnace to the sintering furnace.
