The Gadda group produces multiple types of high-quality continuous furnaces to perform different heat treatment processes.
A typical continuous furnace has the shape of a tunnel with a motorized pulling system that moves the load at a controlled speed through the different sections.
Various advancement systems are offered as motorized rollers and chain transport systems. Different types of heating elements and heat recovery devices are available. Specific thermal profiles are obtained by modulating heating in the different zones.
Forced cooling, spray quenching or quenching tank sections could be added in series.
Excellent furnace temperature uniformity is obtained by CFD engineered forced air recirculation. When needed, air is recirculated in a chamber created between the insulated external panels and an internal stainless-steel panel.
A fan mounted on the furnace floor extracts the air from the load and generates a turbulent flow in the recirculation chamber where air is heated up by the heating elements. Hot air flows back into the chamber from below the parts being treated and transfers the heat to the load. Recirculation fans and heating elements are mounted on plugs for easy maintenance operations.
