T&H Lemont custom welding, straightening units work with existing roll forming line

T&H Lemont has shipped two sets of custom-made welding and straightening units to roll forming customers to be integral components for another brand of roll forming line.

The five-roll weld box has two vertical side rolls, two canted top rolls, and a bottom roll. One of the side rolls and the bottom roll have custom contours to support the profile’s shape. The weld box is followed by a dual OD scarfing unit that has automated, pneumatically powered advance and retract that works in conjunction with the mill’s start and stop activity.

The straightener unit is an eight-roll Turk’s head with fully motorized adjustments in the X and Y axes. The straightener is preceded by several side roll stands that assist the final shaping of the product.
