All raw materials must meet extremely high standards to assure the best quality wire processing. Our in-plant process controls ensures that we produce wire with excellent surface quality, maximum formability and spheroidization. When combined with our Japanese experience and innovative leadership, our Cold-Forming wire production makes Blue Ridge Metals a superior supplier of Cold Heading Quality (CHQ) wire.
Blue Ridge Metals wire processing include pickling, annealing and wire drawing. All are produced and accomplished through control routings that meets or exceed our customer requirements.
Blue Ridge Metals has four computer controlled Short Timed Cycle (STC) annealing furnaces. The roller hearth batch furnaces perform an impressive variety of annealing processes and can process both wire coils and parts for cold forgings. The total combined wire capacity exceeds 80,000 kilograms.
BRM uses it experience and expertise to define annealing methods that will meet or exceed requirements.
Blue Ridge Metals has a variety of wire drawing machines to meet our customer needs. But when it is imperative that the wire be certifiably free of surface defects, Blue Ridge Metals offers a rigorous quality assurance system. Our wire draw eddy current machines examines wire in its prefabricated stage and identifies detrimental surface flaws to a minimum of 0.10mm (0.004 inches). The defect material is marked in such a way that the defective locations can be identified with paint spray markings. Marked material can then be split or rejected during the cold-forming process.
Eddy Current Testing
In some cases the surface can be corrected through the use of wire peeling. The wire peeling process is designed to eliminate seams, surface defects and imperfections such as mill flaws, scratches and decarburization.
BRM's in-plant wire pickling process produces wire with excellent surface quality, maximum formability and spheroidization. Our certified routings are managed from our ERP (Enterprise Resource Planning) software system that ensures proper pickling methods and bath times. These controls ensure that our customer's requirements are met for their specific application.
