Technical Parameters of Atmosphere Generator

Small Split Nitrogen Generator Guidelines

Methanol High-temperature Decomposition Furnace

 

The trolley-type annealing furnace features an all-fiber furnace chamber (saving 30% electricity), automatic trolley sealing, and an integrated rail connection. Its temperature control accuracy reaches ±1°C and is primarily used for quenching and annealing materials such as high-chromium steel, ductile iron, and ship weldments, as well as for heat treatment of mechanical parts.

RX Endothermic Atmosphere Gas Generators

 

As the basic atmosphere for controllable atmosphere carburizing and the protective atmosphere for annealing, it has the characteristics of low operating cost and high degree of automation; compared with nitrogen-methanol atmosphere or methanol atmosphere, it can greatly improve the carburizing quality and effectively protect the decarburization of materials. It solves many atmosphere-related problems in the heat treatment process.

Nitrogen Generator for Heat Treatment

 

As a replaceable gas and annealing protective atmosphere, it has the characteristics of low operating cost and high degree of automation; it effectively protects the decarburization of materials. It solves many atmosphere-related problems in the heat treatment process.

Common Mistakes and Avoidance Methods

Mistake 1: Parts still discolor even when using 99.9% pure nitrogen

Cause: 99.9% pure nitrogen contains 1000 ppm of oxygen, which is 100 times the requirement for bright annealing.

Solution: Upgrade to a truly high-purity nitrogen supply (oxygen content < 10 ppm).

Mistake 2: Oxide scale appears during the cooling process

Cause: Nitrogen flow stops too early. Oxidation may still occur at temperatures above approximately 300°C.

Solution: Continue flowing nitrogen until the parts are cooled to below 250°C. If possible, use a furnace cooling jacket.

Mistake 3: Inconsistent processing results between batches

Cause: Air leakage (from furnace door seals, thermocouple ports) or unstable moisture content introduced by the workpieces.

Solution: Conduct furnace leakage rate testing with soapy water under positive pressure; if workpieces have been cleaned or stored in a humid environment, they must be pre-dried.
