Medium Frequency Converter Melting Furnace

The plant is particularly suitable for the alloys of precious and non-production of grit.
Is composed by :

• medium frequency converter
• Melting furnace with hydraulic or mechanical overturning
• container production grit
• Frame for melting furnace lifting, complete with back stairs and walkway
• Rails for sliding production vessel grit

Converter Features:
• Temperature of cooling water incoming request 25 ° ÷ 35 ° C
• Monitoring of the display of process parameters such as frequency, voltage and power consumption.
• computerized alarm diagnostics for the detection of well 16 alarms or warnings of which the operator must take into account for the proper functioning of the system. Instructions and tips on good working practices are displayed by pressing a button.
• Tracing in memory of the last 20 alarms that have occurred to the machine that allow a rapid diagnosis of any abnormalities.
• closed-loop power control which allows to absorb the power system set regardless of the quantity 'and the type of metal to be melted.
• The internal environment of the converter and 'conditioned by an air-water heat exchanger.

Features of the oven:
The oven is composed of a solid iron structure, with walls of stainless steel of 12 mm thickness in order to minimize losses due to inductive effects. The induction heating coil is immersed in a special refractory cement. Both the crucible that the coil are contained in a thick case made of resin plates and glass fiber.
The crucible tilting system takes place by means of two double-acting hydraulic jacks, with speed 'adjustable.
The rotation of the crucible, without spout, during the overturning is carried out with respect to an imaginary axis passing through the edge of the crucible.
The furnace is equipped with two propane burners that protect the metal from oxidation both during the melting that during casting. It 'also equipped with a timer that automatically shuts off the burner and the water pump of the cooling coil.
