Application
Furnaces of this type are intended for melting aluminum, copper and their alloys. They may also be used for other metals and alloys with a melting point up to 1200 ° C.
Construction
The casing is made of sheet and structural steel with round or square shape.
The heat insulation of the furnace is made of chemically neutral and resistant to various gas environments light-weight refractory bricks, vacuum formed refractory elements, mats and protective coatings.
The heating elements made of new high quality resistance alloys, are arranged evenly over the entire surface of the working space of the furnace.
The temperature is controlled by a programmable microprocessor PID controllers, perceiving direct signal from standard thermocouples located in the workspace of the furnace.
The execution of the furnace ensures minimal heat loss, rapid warming and cooling and high precision of maintaining the set operating temperature.
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.
