Recipient hood for annealing furnaces

摘要

In recipient hoods 1 with gas baffles 2, provided for guiding circulating gas, for annealing processes at reduced pressure and/or excess pressure inside or outside the recipient hood, the stiffness is to be increased and the cost is to be reduced in such a way that the hood wall 3 forms a shell space 5 with the gas baffles 2 formed as a cylinder 4, vertically gas-permeable stiffening rings 7, which transversely pass through the shell space 5, being provided as spacers 6. <IMAGE>
