Project Description

WALKING BEAM REHEAT FURNACE

Installation of new 3,000,000 lb walking beam gas fired reheat furnace consisting of over 12,000 individual pieces. The furnace is used to reheat slabs of steel approximately 9″ thick x 4′ wide by 40′ long weighing 40,000 lbs. The furnace is capable of reheating about 800 tons of steel to 2,400 degrees F per hour. The reheated steel is then rolled into plate steel.
