• Description: This article considers the accumulation of “dirty” material in the weld plates which continually dribbles into the die. This material is often considered dead, but it has been shown that these zones are dynamic and the contamination from the surface and teh ends of preceding billets can continuously feed into the “dead zones” and, from there, into the extrusions’ surface. This article describes experimental work studying the dynamics of the dead zones and includes work published at ET ’12 and more recent work submitted to INALCO 2013, which looks at the effect of feeder plate and shallow pocket geometry on the location and thickness of these surface layers and the resulting streaks.
