Product Specifications

Technical details and manufacturing context for Atmosphere System

Definition
The Atmosphere System is a critical component of Industrial Heat Treatment Furnaces responsible for generating, regulating, and distributing a specific gas mixture (atmosphere) inside the furnace chamber. It prevents oxidation and decarburization of metal workpieces, facilitates processes like carburizing or nitriding, and ensures consistent metallurgical outcomes by controlling the chemical composition of the furnace environment throughout the heating, soaking, and cooling cycles.
Working Principle
The system typically consists of gas supply lines, flow controllers, mixing units, and injection ports. It introduces inert gases (like nitrogen or argon), reactive gases (like carbon monoxide, hydrogen, or ammonia), or prepared mixtures into the sealed furnace chamber. Sensors monitor atmosphere composition (e.g., oxygen probes, dew point analyzers), and feedback controls adjust gas flows to maintain preset parameters, ensuring the protective or reactive atmosphere remains stable despite temperature changes and process demands.

Stainless steel, High-temperature alloys, Ceramic seals
