To produce high quality wire, you need to prevent fouling or damaging of the wire during the annealing process. This is a problem for annealing companies today.
Solution: Avoid metal to metal contact! A new way of thinking is all you need to produce the quality needed in todays demanding world.
When ALF sleeve is installed in the pipe through which the metal wire runs it will avoid the wire from touching the metal of the pipe and becoming distorted. One important aspect when using ALF is the straight alignment of the pipes running through the furnace. This can be obtained by using, for instance, counterweights attached to the end of the pipes. The weights will capture the expansion of the pipe during the annealing process in the furnace.
