Walking beam furnace.

In walking beam furnace, it is often difficult ₉ the good heat evenly su on .allen pages ,. The reason for this is primarily "that the material to be heated rests on the lifting beam for a long time in its passage through the walking beam furnace, so that only insufficient and uneven heat is possible from below"

The. "Invention has now set itself the task, su eliminate the difficulties mentioned and shall ensure, au that a uniform Erifärmung is guaranteed.. 'To solve this problem the invention BeFore suggests ₉ that both the lift and on the Pestbalken Carrying constructions made of highly heat-resistant material, perforated on all sides, are fastened "on which the goods to be warmed up" rests. .
