Copper Components for Electric Arc Furnaces

Application Scope

Winworth manufactures drawing-based copper and copper-steel components for electric arc furnace (EAF) high-current and water-cooled systems. Depending on the installed furnace, the ordered scope may include water-cooled wall panels or roof sections, current-conducting electrode arms, clamps or holders, busbars, water-cooled cables, contact parts, and associated cooling components.

The page does not treat EAF, submerged arc furnace (SAF), and ladle furnace parts as automatically interchangeable. Confirm furnace type, circuit arrangement, phase position, duty, mechanical envelope, and cooling interfaces before selecting a product page or preparing a quotation.

Electrical, Mechanical, and Cooling Interfaces

For current-conducting parts, provide phase and equipment position, electrical path, mating contact surfaces, clamping method, terminal or flexible-connection geometry, bolt pattern, insulation boundaries, movement envelope, support loads, and required surface condition. Any current, resistance, temperature-rise, or conductivity acceptance value must come from the buyer's specification.

For water-cooled parts, define panel or roof position, contour, pipe and manifold layout, supply and return circuits, connections, joints, clearances, lifting points, seals, refractory or slag exposure, and test method. State whether the scope is a copper part, copper-steel assembly, repaired component, or complete replacement assembly.

Material, Manufacturing, and Inspection

Material grade, copper-clad or fabricated construction, plate or tube specification, machining, forming, welding, brazing, heat treatment, joint qualification, and surface treatment follow the approved drawing. The same component name may require a different manufacturing route when current transfer, cooling, motion, and support functions differ.

Inspection may include material and dimensional records, contact-face geometry, assembly alignment, joint examination, specified NDT, cooling-circuit verification, pressure or leakage testing, insulation/interface checks, and trial fit. No current rating, power-on time, cooling performance, or furnace productivity is inferred from a component name.

RFQ Information

Provide the EAF type and position, equipment and component drawings, exact supply boundary, electrical duty specified by the buyer, cooling map, connections, material and construction, mating interfaces, movement and load data, tolerances, tests, quantity, documentation, packaging, and destination.
