Heat or chemicothermal treatment is used to harden surface of parts in a proper way. In most cases the process is carried out in protective gas with developing of necessary carburizing atmosphere.

 

Aichelin is one of the oldest European producers of heat treatment plants and equipment. Nowadays the company is a recognized world leader in manufacturing of high quality systems and equipment for heat and thermochemical treatment of metallic parts. The products of Aichelin have been familiar to the Russian customers since the time of Soviet Union, when Aichelin was the most well-known brand name among westen manufacturers of heat treatment plants and systems.

 

Aichelin manufactures a wide range of plants, systems and equipment, namely:

 

	Heat treatment of parts for automobile industry and machine-building
	Rotary hearth furnace plants Hearth diameter - from 1 m up to 5 m; preliminary heating of parts for subsequent treatment, austenitizing, gas carburizing, nitrocarburuzing, annealing, recrystillizing; as well as in combination with hardening press for hardening with low skellering.
	Pusher furnace plants without protective atmosphere (single- or multi-row); recrystillizing, different types of annealing; heat treatment of light alloys.
	Pusher furnace plants with protective atmosphere (single- or multi-row performance); carburizing, nitrocarburizing, recrystillizing, bainite quenching; as well as in combination with hardening in gas atmosphere under pressure.
	Low pressure carburizing plants (double or multi-chamber performance) for hardening in gas in a cool chamber. High quality and efficiency due to usage of nitrogen at max. pressure of 20 bar (a patented method).
	Heat treatment of fasteners
	Belt furnace plants for heat treatment of mass production parts in bulk or separate parts; for recrystillizing, bainite quenching; nitrocarburizing, tempering and annealing; woven wire coveyor belts or belts from casted rings are used.
	Plants for heat treatment of bearings and other blanks/half finished products
	Roller hearth furnace plants These plants are used for completely automated connection of such processes like nitrocarburizing, annealing, hardening, tempering, heat treatment of light metals as well as QUELLFLUTENR process for hardening with low skellering in an oil or salt bath.
	Thermal equipment and systems
	Vertical retort furnace plants Max. diameter is 4 m, max. depth is 10 m; for gas carburizing, nitrocarburizing, nitration, recrystillizing, all types of annealing, brazing and tempering.
	Chamber furnace plants Multifunctional chamber furnace plants with a preheating chamber and an integrated quenching bath, alternatively working  in throug pass mode; for recrystillizing, nitrocarburizing, gas carburizing, repeated carbonization, hardening, normalizing, nitration and oxidation.
	FLEXICLEANR System for cleaning and vacuum drying of parts before and after heat treatment. Some water solutions and neutral washing agents are used. VACUPEARLR: cleaning technology at low pressure.
	Protective gas generators for generation of protective, blowing or basic gas.  Endomat: generation of basic gas for nitrocarburizing and hardening. Nitromat: generation of  inert gas for neutral atmosphere and blowing.
	Heating units technology  NOXMAT
	NOXMATR Efficient recuperator burners for direct and indirect heating in industrial furnaces; in performance from steel or ceramic.
