PROPER CONVEYOR OVEN DESIGN INCREASES MANUFACTURING PRODUCTIVITY

摘要

As users of industrial conveyor ovens, you likely want to increase productivity by finding the best match between your manufacturing process and the oven. In pursuit of this goal, certain factors must be considered and decisions must be made if oven designers and manufacturers are to be successful in helping oven users achieve their goals. This article aims to shed light on design points that seem small but often have a large impact on oven design. Operating temperature is an area that is often a source of unexpected adjust- ments. The two most common operating temperature ranges where unexpected adjustments are needed are low temperature (less than 150℉ [65℃]) processes and those in the 450 to 600℉ (232 to 315℃) range. In a typical conveyor oven, the heat source will be infrared, infra-air (a combination of infrared and internal recirculating airflow), and electric or gas hot air convection. The choice of heat type is first based upon the substrate and the heat source that best matches it.
