Furnaces of this type are used for heat treatment of steel details. They may be used for annealing, tempering, hardening, normalization, and other processes that require heating of details up to 1000 ° C.
The furnace casing is made of sheet and shaped steel sheets.
The thermal insulation of the furnace is made of chemically neutral and resistant to various gas environments light-weight refractory bricks, rigs, vacuum formed refractory elements, felts, mats and protective coatings.
The heating elements made of new high quality resistance alloys, are arranged appropriately in the working chamber.
The temperature in the furnace chamber is regulated by a programmable microprocessor PID temperature controller, adopting direct signal from a standard thermocouple.
The door of the furnace is operated automatically using hydraulic cylinders and hydraulic station. There is a blocking of the power supply to the heating elements when opening the door.
In front of the furnace is installed a loading fork which is serviced manualy.
Electrical switchboards are designed for power and control of the furnace with operating voltage according to the design and the control of the thermal processes. The electrical switchboards provide appropriate control and protection of the circuits and automation, providing the required security.
The electrical resistance furnaces and respectively the switchboards for powering and management work with three-phase mains voltage (380 V) – to power the load chain and 250 V for control circuits (command and protective circuits related to the safety).
Available furnaces of this type are made in accordance with the technical assignment of the client and in accordance with the requirements of the technology for heat treatment of the products.
