Eck Industries, Manitowoc, Wis., operates a specialty aluminum foundry that manufactures various sand-cast aluminum parts for the automotive, defense, and other industries. The foundry operates 24 hours a day, 7 days a week, and makes more than 3,500 different cast-aluminum parts weighing as little as 1/2 pound to more than 2,000 pounds. About 2 years ago, the company decided to expand the foundry and install a thermal sand-reclamation system to reclaim up to 6,000 lb/hr of sand for reuse in the casting operation. Because of the sand’s abrasiveness, the company needed to use special pipe and elbows in the system’s conveying lines.
