This document provides information about a bell type furnace system for heat treating metals in the armament industry. The furnace is a SOLO Swiss Profitherm 500 that can perform hardening, carburizing, and austenitizing processes. It has a salt tank, furnace, washing machine, and salt recovery system. The furnace can reach 950°C and the salt tank 450°C to heat loads up to 700mm in diameter and height. It offers advantages like simple automation, modularity for future needs, a second furnace for increased production, and minimized part deformation through salt quenching.
