13 Annealing Boxes for a defined Protective Atmosphere for use in Chamber and Pit-Type Furnaces with Air Circulation

N 250/65HA with protective S 120/65A with annealing box and gas annealing box cooling platform for fast cooling

Annealing Boxes for Models N 30/45 HA - N 500/85 HA, S 30/45A - S 500/85A Using annealing boxes, you can operate our standard air circulation furnaces, models N 30/45 HA - N 500/85 HA and models S 30/45 A - S 500/85A, under a defined protective atmosphere. This allows processes such as bright annealing, annealing under protective gas, or curing of copper alloys.

On standard models, the boxes are equipped with a lid and a protective gas inlet and outlet. The lid is sealed by means of a sealing channel with a high-temperature gasket before loading into the furnace. The furnace is equipped with a special pass-through for the box inlet and outlet connections. The box inlet is connected to a gas supply panel. We have gas supply panels available for either manual or automatic control.

As a vacuum model, the box allows air evacuation in cold condition before refilling with protective gas. This system is particularly useful for bright annealing of bulk materials, since the oxygen can be more efficiently removed from the box by means of pre-evacuation than through purging alone. In our modern research center we can carry out tests and experiments to demonstrate how these boxes perform with your materials.

Automatic gas supply panel for annealing  Protective gas inlet and outlet box  Sealing channel with high-temperature gasket  Made of high heat-resistant stainless steel 1.4841 (314)

Electrically heated convection chamber furnace with air circulation N 4000/26AS for drying of foundry cores with an alcohol- based binder

Safety Technology for Chamber Furnaces

Ship-lock type furnace N 560/26 with Certain processes release solvents or evolve other flammable vapors when heat is applied. The concentration of safety technology, front charging and rear these vapors must be kept below a certain limit to prevent ignition. European Norm EN 1539 (formerly VGB4) and unloading NFPA 86 in the USA describe these limits, and proscribe safety equipment to ensure these limits are not exceeded.

For appropriate applications and processes, all air circirculation furnaces of the series N ../45HACLS (page 13), and N ../26A, or /45A (page 10/11) are available with safety technology for protection of ignition in the furnace chamber.

To prevent ignition, flammable vapors must be diluted with air. Special care must be taken so high concentrations of flammable materials do not accumulate in “dead” areas within the furnace. For this purpose, the furnaces are equipped with an exhaust gas fan, providing a defined suction flow. A measurement system monitors this flow. In parallel, the furnace atmosphere is diluted by the inflow of fresh air. The air circulation is also monitored by the measurement system. Furnaces with a capacity greater than 1000 liters are additionally equipped with an explosion pressure relief.

Sealed annealing box Annealing tray with alloy bag and Annealing box with protective gas Annealing box with protective gas inlet protective gas inlet inlet and outlet and outlet, constructed for evacuation at ambient temperatures

Our protective gas and carburization modules allow you to upgrade our annealing and hardening furnaces into a compact annealing and hardening system as an economical alternative to expensive vacuum systems and protective gas furnaces. We can recommend different systems based on your application. Our professional R & D department will be pleased to test your product samples in order to specify the right heat treatment equipment for you.

 Annealing Box Our annealing boxes with lid sealing may be used for carburizing, annealing and hardening in neutral atmospheres, powder nitriding or boriding. Your charge is placed in the box and bedded in carburizing granulate, neutral annealing coal or nitriding or boriding powder. The box is sealed, and when heated, the resulting atmosphere in the closed annealing box provides for the respective surface reaction of the charge. Automatic gas supply panel for 2 gases For carburizing and similar processes, the annealing box may be removed while hot, opened and the charge with flow meter and solenoid valves quenched in fluid. For annealing processes, the box may remain in the furnace until it is cooled down.

 Annealing Tray with Alloy Bag This system, consisting of a lightweight tray with gas port and alloy bag, is particularly useful for air-quenched steels. The thin-walled alloy bag allows fast heat transfer. Its protective gas connections allow you to process your charge in a defined atmosphere. The small size of the gas lightweight tray you to pre-flush or cool the unit outside the furnace or place it on a cooling table for fast cooling by fan.

 Annealing Box with Protective Gas Inlet and Outlet The boxes are equipped with lid and protective gas inlet and outlet. The lid is sealed by means of a sealing channel with a high-temperature rope gasket before it is introduced into the furnace. The furnace is equipped with a special passage for the protective gas connections. The box is connected to a gas supply panel to introduce the required atmosphere in the box. When the heating process is finished, the box may be removed from the furnace, the lid removed and the parts quenched in liquid or air.

 Annealing Box with Protective Gas Inlet and Outlet constructed for Evacuation Ambient Temperatures This version of our annealing box is designed to be evacuated prior to the heating cycle. After evacuation, the box is refilled with a protective atmosphere for the heating cycle. This system is particularly useful for bright annealing of bulk materials, and nonferrous and noble metals, since oxygen can be more efficiently removed from the box by evacuation than through purging. Temperature-resistant seals allow this version of the annealing box Sophisticated gas supply system to maintain a vacuum at ambient temperatures.

 Additional Accessories In addition to the above-mentioned protective gas and carburization systems, Nabertherm has a variety of heat treatment accessories ranging from the sealing cords for the annealing boxes to fully automatic gas supply panels. Please check on Heat Treatment II catalog.

SHS 41 This compact system is very suitable for hardening under protective atmosphere and subsequent quenching of the charge under protective gas in oil. Hence, this system can be used for hardening processes that would otherwise require complex furnace systems. In our modern research center we can carry out tests and experiments with different materials to specify the right heat treatment process for you.

An annealing box with protective gas port containing the work pieces is charged into the furnace. After finishing the heat treatment, the box is extracted out manually and placed onto the quenching facility. Reaching the rear trigger, the box bottom automatically lowers into the hardening oil, and is moved up and down. The space above the oil surface is flushed with protective gas to displace oxygen in order to avoid ignition.

34 Furnace 1 Furnace 2 Cooling station Furnace 3 Furnace 4 Unloading

Furnace 8 Furnace 7 Cooling station Furnace 6 Furnace 5 Loading

Fully automated Furnace Plant consisting of 8 x W 1280/70AS This fully automated tempering plant consisting of 8 air circulation bogie hearth furnaces, two cooling stations and loading and unloading facilities, Nabertherm offers an ideal solution for many heat treatment processes. The loading and unloading stations buffer the continuous processes before and after the heat treatment system. If necessary, the plant can be equipped with exhaust gas treatment facilities including after burner systems.

After the operator has released the fully loaded bogie at the charging station, the system runs automatically without further operator intervention. The shuttle delivers the charge into the selected furnace. With the electro-hydraulic lifting doors closed, the heat treatment process starts. When the 24 hour long temperature program is finished, the charge is transferred into one of the two cooling stations, where it stays until a safe handling temperature is reached. The shuttle then transports the charge to the unloading facility. If the facility is occupied the charge will be stored on a buffer station until the unloading area is available. The Nabertherm- Software Control Center (NCC) takes care of control, visualization and documentation.

The system shown below can be expanded or adapted in modular steps to meet your individual needs.
