SOLO Swiss Mesh belt furnace for the heat treatment of fastener systems

SOLO Swiss, manufacturer of atmosphere furnaces since 1945, delivered 2 furnaces type 302-60/500 to a fastener systems manufacturer in France and in Germany.


This SOLO Swiss heat treatment production line is equipped with an electrically heated belt furnace for temperatures up to 950°C, a 450°C salt quenching tank designed with a carrousel based extraction, a transfer tank, a washing system for an automatical washing after salt quenching, and a salt recovery system. This new furnace, as the entire SOLO product range, is powered by AXRON Swiss advanced process control.

This production line has an effective capacity of 300 kg/hour, with an effective heating zone of 630mm (width) x 5000mm (length) x 120mm (height), and has a total heating installed power of 420 kW.

Thanks to advanced atmosphere control based on protective gases (nitrogen, methanol), as well as gases additions for set point regulation (natural gas, propane, air) combined with measurement probes enabling both austenitizing and carburizing, SOLO Swiss succeeded in meeting the strict specifications of the customer’s metallurgical requirements.

This furnace exhibits the following unique advantages:

–   High precision and perfect homogeneity of heat treatment

–   No risk of mixing between sets of parts due to the sequential carrousel based quench tank

–  Compliant with the most stringent environmental requirements (reprocessing and recycling of washing waters, salt recovery)

–  Process control, M.E.S. and supervision by Axron Swiss
