| 摘要 |
PURPOSE:To keep pressure in inner covers constant, by covering lower end portions of outer circumferences of the inner covers and projected portions of seal plates of an annealing furnace of a multi-type steel plate coil with heat insulating materials, to prevent the blowoff of atmospheric gas in the inner covers due to the thermal deformation of the seal plates. |
