Chamber electric furnace resistance with protective atmosphere is gas-tight enclosure. As the protective atmosphere is usually nitrogen or argon (in flasks). Shielding gas runs through one of the ports in the sidewalls of the furnace. When the oven creates a slight overpressure (2 ... 5 mm.vod.st. is manometers) to prevent air leaks. There shall be no oven aggressive or conductive gas can damage the elements of the oven. Electric furnace system is equipped with automatic temperature control on the basis of solid-state non-contact relays and programmable digital thermostat sets the temperature, time to treatment and time spent on the operation. Maintaining temperature stability in a steady thermal conditions in the temperature range of 400 ... 1250 ° C, without the cages of at least ± 3 °C.
Heaters of superfehral placed on the tubes in the recesses of the side and end walls of the furnace chamber in the hearth. Hearth heaters covered with ceramic tiles. The furnace lined with modern energy-saving materials. In an oven heat treatment may be carried out in air without using shielding gas. It includes welded tray of heat resistant steel 20H23N18, 8 mm thick, with ribs and thermo-compensation cuts.
