Technology Update

the coils are automatically purged with protective atmosphere (N 2 + H 2 ). Working on a step continuous basis, the stacks are transported by rollers from one stationary position to the next. Once a pre-set cycle time has elapsed the stack is driven into the vacuum chamber where a vacuum is created. After a predetermined time, the chamber is then refilled with the process protective atmosphere, and the stack is advanced into the entry vestibule, where it remains for one cycle before going into the furnace. The high convection furnace is indirectly heated under protective atmosphere, and the complete line from entry vestibule to the end of the cooling zone remains under protective atmosphere 100 per cent of the time. The stack of coils moves through the furnace on a step continuous basis during which time the coils are automatically purged by the CTP system. This serves the purpose of removing any oil from the bores of the tube as it vaporises, which assists in producing the so called ‘Super Clean’ tube. At the end of the heating phase the stack is passed into the cooling section, where

the material temperature is reduced to a level below that which copper oxidises when it comes into contact with air. The stack is then discharged from the line via the exit vacuum chamber, it is transported to the destacking device, and the coils are removed from the separated trays. A complete materials handling system is included for the conveying, stacking and de-stacking of the work trays.
