BTU INTERNATIONAL

BTU’s Walking Beam is a high temperature thermal processing system that provides continuous temperatures up to 2000°C under precisely controlled temperature and atmospheric conditions, in a full range of oxidizing and reducing atmospheres. Typical applications include high temperature metal and ceramic sintering and uranium and gadolinium processing for power generation.
The patented beam transport system is designed with high stacking capability for processing heavy loads. Product carriers are designed specifically to support individual stacks for greater thermal and payload efficiencies. The beam system maintains product spacing during processing with no hearth or carrier abrasion, minimizing maintenance.
BTU provides direct worldwide support for installation and startup of all Walking Beam systems, which are also backed by a comprehensive warranty program.

Walking Beam Product Movement
Patented wheel and inclined plane beam movement system maintains proper spacing and eliminates friction between product and furnace parts.
Custom Refractory Materials
Alumina refractory insulation eliminates product reaction and provides easy removal for maintenance, minimizing downtime.
Flame Barriers
Barriers at furnace entrance and exit burn off potential contaminants and provide optimum atmosphere integrity.
Atmosphere Sampling Ports
Sampling ports in all heated zones offer maximum temperature control.

Multi-Atmosphere Capability
Walking Beams operate in nitrogen/inert, hydrogen (dry or wet), and air atmospheres or a combination depending on process requirements.
Atmosphere Saturator
Maintains proper dew point conditions through closed-loop temperature and water level control.

Return Conveyor
Aluminum rollers and alumina friction cross tables provide long, contamination-free process life. 
Multiple Heater Types
A range of heater types (Silicon Carbide, Molydisylicide, Molybdenum Ribbon, Tungsten) are available to handle high temperature applications up to 2000°C.
