Overview of Vacuum Arc Remelting (VAR) Furnaces
Consarc Corporation specializes in the production of Vacuum Arc Remelting furnaces, crucial for manufacturing specialty steels, superalloys, and reactive metals like titanium. The VAR process involves melting an electrode in a vacuum to produce high-quality ingots with enhanced material properties.

VAR Process Description
The process starts with loading the electrode into the furnace, which consists of a movable furnace head and a fixed melt station. The electrode acts as the cathode, and the crucible base as the anode. A high current arc creates a molten metal pool, with precise control over the arc gap and melt rate to ensure directional solidification and minimize segregation.

Automatic Melt Controls
Consarc's Generation 7 Automatic Melt Controls use a SCADA system for precise melting process control. It includes a PLC for logic functions, a dripshort processor for monitoring short circuits, and a PC interface for data logging and analysis, allowing for detailed customization and consistent results.

Power Supply Technology
Consarc designs its own DC power supplies, offering Variable Reactance Transformer (VRT) and Thyristor SCR based units. These water-cooled power supplies are tailored to meet VAR application demands, ensuring reliable and stable power delivery.

Advantages of Consarc VAR Furnaces
Consarc VAR furnaces address issues like uncontrolled metal stirring and alloy segregation. Features include coaxial design for melt uniformity, precise electrode positioning, and automated systems for ease of operation. They are designed for safety, especially with reactive metals like titanium.

Furnace Configurations
Consarc offers a variety of standard and custom VAR furnace sizes to meet different customer needs, equipped with advanced safety features and configurable for primary or secondary melting processes.

Conclusion
Consarc's VAR technology provides a robust solution for producing high-quality metal ingots, with advanced control systems and proprietary power supply designs offering superior performance and safety in remelting specialty and reactive metals.

Safety Features
Includes argon gas purged valves, emergency argon backfill, and protective concrete bunkers. The ram drive system prevents excessive arc gap, ensuring safety during operation.

Additional Equipment
The Vacuum Stub Welder is an adjunct to the RVAR furnaces, allowing electrode stubs to be welded under vacuum, optimizing furnace time for remelting.
