The furnaces of this type are designed for heat treatment of steel details. They can be used for tempering, normalization, annealing and other processes that require heating of detail up to 1000 ° C.
It consists of a furnace equipped with mechanized horizontal conveyor for moving details subject to heat treatment.
The casing is made of sheet and structural steel.
The thermal insulation is made of chemically neutral and resistant to various gas environments light-weight refractory bricks, rigs, vacuum formed refractory elements, felts and 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 heating zone of the furnace is regulated by PID microprocessor-based programmable temperature regulators, perceiving direct signal from standard thermocouples.
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.
