GRAIN PRODUCTION SYSTEMS WITH A PROTECTIVE ATMOSPHERE

Technical specifications of the plant:

• Possibility to create an over-pressure in the upper chamber in order to clean the internal die
• Water cooling by heat exchanger in order to maintain the water temperature constant from the first to the last cycle
• Melting, pouring, grain tank loading and discharge operations are controlled by a PLC unit with a touch-screen panel, able to memorise various melting programmes according to the type of alloy to be molten
• The converter is provided with a centrifugal pump placed inside the converter’s frame to be used for the recycling of the cooling water. The above pump is equipped with a pressure switch, thermals, fuses and a timer for the automatic stop. You need only a demineralised water storage tank or a water chiller.
• Monitoring on the display of the various process parameters (frequency and absorbed power).
• Computerised alarm diagnostics for 12 alarms which the worker must take note of for the system to work properly. By simply pressing a button, instructions and advice appear on the display.
• Closed ring power regulation which allows the system to absorb the set power regardless of the quantity and type of metal to melt.
• The internal environment of the converter is conditioned by an air-water exchanger.
