*AUTOMATIC SINTERING MACHINE MOD. 18STV, WITH CONTROLLED ATMOSPHERE, ONE STATION, 120Kva THREE-PHASE, 95 TON.

 

Main features

        Sintering machine suitable for the production of average and large size segment series, continuous rim blades, grinding wheels for glass and other diamond tools.

        Mould heating system for direct passing of direct current (Joule effect).

        Sintering with steel and graphite moulds.

        Sintering under controlled atmosphere by means of vacuum/inert gas programmable wash.

        Type K thermo-couple for operating temperatures up to 1000C.

        Plates cooling, transformer and vacuum chamber with flow visualisation and water temperature.

        120kVA three-phase transformer, (max. power supply is limited electronically to 210A) by switch for 3 different tensions between the electrodes(maximum power limit for heating).

        Controller program with cycles divisible into 12 steps. each step includes:

         temperature

         pressure

         max. power limit

         heating time

         holding time

        Compression force controlled electronically (loop system)

        Process data visualisation (set and real) and alarms.

 

Options

        Bar code for selecting sintering programs.

       Temperature control 350-1300C by infra-red rays pyrometer

        Type R thermo-couple for operating temperatures up to 1200C.

        Additional control thermo-couples.

        Segment height control while sintering takes place (linear transducer on cylinder, resolution of 0,01mm)

        Minimum compression force reduction system (from 4200 to 2400kg).

        Data acquisition system on external PC.

        Electrodes in graphite and amorphous carbon.

        Graphite plates.

        Graphite moulds.

        Aluminium frames.

        Prearrangement for modem installation for remote assistance.
