Description
This paper will discuss recent developments in graphite furnace technology widely used in the production of oxygen-free copper wire rod. This includes high-speed casting of 8-mm rod at 5 m per min., reducing the need for operator intervention and space requirements, and the optimization of thermal balance in a graphite high-intensity heating system. Other novel features will be described, including improved versatility of machine design to permit rod casting from 8- to 30-mm diameter production of high-copper alloys.
