Reducing heat loss in pusher-type continuous reheating furnaces

One of the rolled-products shop at the Chelyabinsk combine has begun to use heat-insulating elements in the form of two half-rings to line the glide tubes in its pusher-type continuous furnace. The half-rings are attached to the tubes by welding. The inner layer of each element is made of 10-mm-thic...

Zusammenfassung:One of the rolled-products shop at the Chelyabinsk combine has begun to use heat-insulating elements in the form of two half-rings to line the glide tubes in its pusher-type continuous furnace. The half-rings are attached to the tubes by welding. The inner layer of each element is made of 10-mm-thick refractory mullite-corundum panels of grade MKRKG-400, while the outer layer is made of refractory concrete 50 mm thick.
