ABSTRACT:
A refractory sheathing made from insulating shapes for vertical support members, in particular riser pipes, in heat-treating furnaces, e.g., pusher furnaces, comprises an inner layer made from a refractory, fibrous, insulating material, or an appropriately shaped article, surrounding the support members and an outer layer of positively interengaging, refractory, shell-shaped shapes of, for instance, the same height throughout, surrounding said inner layer. To avoid a large number of different shapes having to be correspondingly expensively manufactured in different moulds to match support members of different dimensions and double pipes, it is proposed that only equal-leg angle pieces of different leg lengths, in particular two different angle pieces, and straight intermediate pieces of different widths, in particular only two or three widths, be provided as shapes. All shapes have grooves on two contiguous sides at right angles and matching tongues on both of the other contiguous sides at right angles. The inner layer surrounding the support members is formed from set-up, substantially rigid, flat insulating boards.
