Furnace for preheating and tempering under nitrogen atmosphere

Convection furnace for preheating, tempering and heat treatment in temperatures of up to 650°C. The furnace body is gastight and can be equipped with nitrogen supply for heat treatment under nitrogen atmosphere. A powerful fan placed underneath the charge ensures rapid heating and good temperature uniformity. The temperature is controlled by a digital controller, but the furnace could also be equipped with a programmable controller.

The furnace can be used as a single furnace or form part of a furnace line. It can be equipped with charge supports for various types of charging machines.

As an option the furnace can be supplied with pre-ventilation when preheating and tempering charges where there is a risk of oil smoke.

Convection furnace for nitriding and nitrocarburizing as well as tempering and annealing under protective atmosphere

Convection furnace for nitriding and nitrocarburizing as well as tempering and annealing under protective atmosphere in temperatures of up to 750°C. The furnace body is welded gastight and the furnace door is equipped with a locking device with an inflatable silicon rubber seal. The furnace has a safety waste gas burner system for combustible process gases. The process gases can be chosen for the desired type of nitriding, nitrocarburizing, tempering or annealing process. A powerful fan placed underneath the charge ensures rapid heating and good temperature uniformity. This design also enhances the circulation of the atmosphere, granting uniform nitriding and nitrocarburizing results. An integrated cooling system for cooling the charge after completed process helps shorten the total process time.

The furnace is controlled by a controller/PLC system and is operated via a panel. The PLC system incorporates a modem for fast service and support.

The furnace can be used as a single furnace or form part of a furnace line. It can be equipped with charge supports for various types of charging machines.

Multipurpose furnace for heat treatment under protective atmosphere

Multipurpose furnace with high capacity and high process quality for mass production and hardening of tools etc. In the multipurpose furnace different processes can be run, such as carburizing, carbonitriding, nitrocarburizing and neutral heat treatment with quenching in oil or cooling under protective atmosphere. The furnace atmosphere is controlled by the furnace controller in combination with an oxygen probe.

The multipurpose furnace is operated from a panel where all functions are graphically indicated. The furnace carries out the pre-selected processes automatically and with full reproducibility. All data from the process are logged. A superior system could also be connected for logging and process control.

The furnace can be used as a single furnace or form part of a fully automatic furnace line consisting of Sarlin's multipurpose furnace, tempering and preheating furnace, charging machine and washing machine as well as charging and discharging tables.
