Controlled Atmosphere Heat Treatment Furnace for Stress Relieving & Precision Processing

A controlled atmosphere heat treatment furnace is high-end precision thermal processing equipment that realizes artificial adjustment and stable control of internal furnace gas composition, concentration and pressure. By filling specific protective gases such as hydrogen, nitrogen and inert gas and maintaining stable sealed atmosphere environment, it completely isolates external air, oxygen and moisture, realizing oxidation-free, decarburization-free and pollution-free precision heat treatment of metal workpieces. It is core equipment for high-precision metal stress relief, bright sintering, bright annealing and high-standard surface modification treatment, and is widely used in precision machinery, electronic components, aerospace and high-end hardware industries.

As a typical application of controlled atmosphere equipment, the stress relieving furnace is specially used to eliminate internal residual stress of metal workpieces after welding, stamping, forging and machining. Long-term residual stress will lead to gradual deformation, size deviation and structural instability of finished parts during use. After precise atmosphere protection and slow cooling stress relief treatment, the internal crystal structure of metal materials tends to be uniform and stable, effectively improving material dimensional stability and service life. Equipped with professional hydrogen atmosphere system, the hydrogen atmosphere sintering and hydrogen annealing processes can form ultra-clean and bright metal surface, completely replacing traditional pickling, polishing and passivation processes, reducing production links and environmental pollution while improving product surface quality.

All controlled atmosphere heat treatment furnaces are equipped with intelligent atmosphere monitoring and automatic compensation system, which can real-time monitor and automatically adjust gas concentration and flow to ensure stable and consistent furnace atmosphere environment. The multi-zone temperature control technology ensures uniform heating of workpieces, avoiding local overheating and insufficient stress relief. The equipment runs stably for a long time with high processing precision and strong process adaptability, and can be customized according to customer material characteristics and process standards, providing high-precision and high-stability heat treatment solutions for high-end manufacturing enterprises.
