Furnaces of this type are intended for melting and holding of aluminum and aluminum alloys. They may also be used for melting of other metals with a melting point up to 1200 ° C.
The casing is made of sheet and structural steel with square shape.
The furnace is equipped with a crucible located in the workspace. In the crucible are loaded metal blocks to be melted.
On top, the metal crucible closes with a well-sealed heat insulated lid. Tilting of the furnace is performed with hydraulic cylinders supplied by a hydraulic station.
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.
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.
