Each ceramic fiber block is temporarily supported by a supporting member and bar combination previously secured to the furnace casing, before it is finally secured to the casing by another supporting member and bar combination. No separate means for holding the block temporarily is required. As ceramic fiber blocks and supporting members are alternately attached to the casing, it is possible to ensure intimate contact between every two adjoining blocks. The absence of any extra work for holding the blocks temporarily improves the efficiency of the block installation work. |
