Expanded metal is a common product throughout the world and much expanded metal goes through a rolling mill. These are normally very large 2-high or 4-high rolling mills that are very expensive. The top two rolls is where the reduction is taking place. This mill has only 16” diameter rolls. The lower roll has a
Precision measuring normally requires an entrance gauge, which records the thickness of the material going into the rolling mill. This is referred to as anticipatory automatic gauge control. The entrance thickness gauge adjusts the rolls in microseconds if there are any changes in thickness. The exit gauge records the thickness, and the rolls adjust based
All rolling mills should be equipped with an apron to feed and receive the part or strip. The material can be niobium, tantalum, titanium, or aluminum. These rolling mills require very large separating forces and an apron to feed and receive the small pieces at the passline of the rolls. These high strength aprons are
Expanded metal is used primarily for grating, filtration media, and fencing. Carbon and stainless steels can be perforated with holes or expanded to a diamond shaped pattern, which reduces the surface area. When an expanded metal is made, it is sometimes skin passed, which removes any burrs from elongation process. It also improves the expanded
