Copper Components for Vacuum Arc Remelting Furnaces

Application Scope

Winworth manufactures drawing-based water-cooled copper components for vacuum arc remelting (VAR) furnaces. The primary solidification component is commonly identified as a copper crystallizer or mold; some equipment documents may use crucible terminology. The buyer's furnace drawing controls the formal order name.

VAR continuously remelts a consumable electrode by an electric arc under vacuum and forms a new ingot in a water-cooled copper mold. This process position is different from an EB cold hearth and from an ESR water-cooled mold surrounding a slag pool.

Ingot, Electrode, Base, and Vacuum Interfaces

Provide the furnace arrangement, consumable-electrode and ingot relationship, round, square, slab, or other ingot section, cavity dimensions and taper, active and overall length, hot-top region, baseplate and starter interface, withdrawal or stationary arrangement, flange, support and alignment datums, seals, chamber clearances, lifting, removal, and maintenance access.

Cooling documentation should identify the copper body and outer jacket relationship, supply and return paths, channel or annular-space construction, partitions, inlet and outlet orientation, pipes, plugs, closures, joints, circuit separation, monitored points, and the buyer's pressure or leakage test.

Material, Manufacturing, and Inspection

Copper grade and condition, forged, rolled, cast, machined, drilled, fabricated, welded, or assembled construction, outer jacket, joining procedure, cleaning, and surface requirements follow the approved furnace specification. No material label alone establishes arc stability, melt rate, ingot quality, or furnace compatibility.

Inspection may include material records, cavity and taper, wall and flange geometry, concentricity and alignment, base and chamber interfaces, cooling-passage verification, joints and closures, specified NDT, pressure or leakage testing, circuit separation, cleanliness, and trial fit. No vacuum level, current, melt rate, ingot size, chemistry, defect reduction, or service life is claimed from the component alone.

RFQ Information

Provide the VAR furnace and crystallizer drawings, consumable-electrode and ingot data, stationary or withdrawal arrangement, exact supply boundary, copper and jacket specifications, full cooling map, baseplate, chamber and support interfaces, tolerances, cleanliness, NDT and test procedures, quantity, documentation, packaging, lifting, and destination.
