The Rotary Retort furnace is designed to uphold the superior quench hardening performance required for uniform heat treatment of small parts, with the maximum temperature in the furnace being 950oC. An adjustable speed heat resistant cast retort fitted inside the Rotary Retort furnace facilitates constant motion for the work piece - for both uniform heating and carburising. Rotary Retort furnaces from HIGHTEMP are predominantly well suited for carburising of small components such
