Cleaning and coating of wire using the EPCAD process

Cleaning and coating of wire using the EPCAD process

$15.00

This paper relates to the use of EPCAD technology to clean and coat steel wire. In cleaning, the wire or wire rod is passed through an electrolytic cell in which the wire is grounded and serves as a cathode while being sprayed or irrigated with a sodium-based electrolyte (e.g., sodium carbonate) which passes through an anode held at high DC voltage (typically 150 to 200V). This paper describes the process, outlining how it works and using electron microscopy to reveal the various processes responsible for the removal of mill scale.
