Descriptions

·Furnace body

    Tapping manners: spout and EBT. Tubular water-cooled and

    traditional foof are available.

·Tilting mechanism.

·Electrode lifting mechanism

    It can be realized by bogie movement or mast lifting, common copper

    tube arm or advanced water-cooled conducting arm are available.

·Roof lifting and swinging mechanism.

    Integrated or separated foundation designs for your choice.

·Cooling-water monitoring and alarming system.

·Hydraulic station and control valves system.

·Electric control system:

    Automatic regulator of electrode lifting can be VVVF controlled or

    computer controlled. The later can equipped with CPT displayer.

The acting of all parts and interlocks is controlled by PLC.
