Forced circulation furnaces

Chamber resistance electric furnaces with forced atmospheric circulation are intended for operation in industrial conditions of thermal sections of production.

 
A key feature of the furnace is the high uniformity of the temperature field inside the working chamber.
A wide range of tasks:
• Heat treatment of non-ferrous metals.
• Soldering in protective atmospheres.
• Diffusion annealing
 
 
Technical features:

• Multilayer lining.
• Lining materials are safe for operating personnel, confirmed by hygiene certificates.
• Type K main thermocouple
• Regulation of the heating process - microprocessor PID controller.
• The circulation inside the furnace atmosphere is carried out by a fan located on the rear wall.
• Ceramic penetration to accommodate an extra thermocouple.
• Four-sided heating - under, ceiling, left and right sides.
• The inner chamber is made of high quality polished stainless steel.
• Door opening - hinged.
• The location of the control controller directly on the furnace body.
• Thermocouples used in the furnace are made in Russia, entered into the state register of measuring instruments, have a full set of metrological documents.


 
Main technical specifications:

• The working space of the furnace chamber, l .. - from 30 to 500, large sizes by prior agreement
• Maximum operating temperature of the furnace, ° С - up to 850
• Temperature uniformity during holding, ° С - ± 5, higher values ​​are achievable with additional furnace settings
• The number of zones for regulating heaters, pcs. - 1.
• Accuracy of regulation, ° С - 1
• Types of possible controllers - TERMODAT, Nabertherm, Schneider-electric
• Number of heating sides, pcs. - 4 (under, ceiling, left and right wall)
• Location of heaters - between the inner working chamber and the furnace body with the main lining.
• Ceramic penetration to accommodate an additional thermocouple as part of a fireproof plug.
 
The composition of the resistance furnace with forced circulation:

• Oven body.
• Supporting metal frame to accommodate the furnace body.
• Oven control controller.
• Thermocouple.
• A set of cables for connecting to power.
• A set of documentation in Russian.
 
Options for expanding functionality:

• The supply of protective gas to the working chamber of the furnace - allows you to reduce the effect of oxygen on the surface of the treated cages.
• Increased regulation zones by heaters; the option improves temperature uniformity.
• Control of the furnace by thermocouple placed on the processed sample.
• Heat-resistant boxes - allow to provide high purity of protective gas, processing of parts in bulk, heat treatment in powders.
• Managed exhaust flaps — Provides controlled cooling.
• Fan to purge the furnace chamber with external air - allows you to speed up the cooling process, and this option is also necessary for controlled cooling of the charge.
• Accessories for complex part geometries and / or suspended parts.
• Thermist personal protective equipment (mittens, masks, aprons).
• Hand tools for loading / unloading the furnace.
• Connection of the furnace controller to the enterprise IT network.
• External registrars, including paper recorders.
