Harper’s patented Vertical furnace systems are our latest thermal processing innovation for a wide range of product feedstocks, particularly for materials requiring high temperature solid-solid and solid-gas reactions, such as carbides, nitrides, borides and refractory metal powders.
This new system is a design alternative to other traditional furnace types, with the following advancements:
-Minimizes the opportunity for product sticking or gas-phase entrainment during processing
-Maximizes product uniformity and reaction time by minimizing or eliminating bulk bed effects
-Provides better heat and mass exchange between products and reactants for improved efficiency
-Limits heating and cooling requirements to the process material only – containment remains at temperature and the process material moves through it
In Harper’s Vertical Conveyor furnace, reactions occur more uniformly and quickly over the surface layer of material, and off-gassed material exits the process upwards and away from the product. The system’s specialized material movement limits the potential for overheating problems, such as melting/sublimation, sintering or excessive grain growth. In addition to the container-less nature of the design, thermal transfer between product and reactants significantly improves the power efficiency of the unit.
