A roller for a high temperature annealing line includes a cylindrical shell and an axial support element and including a spindle at at least one of its ends, and first and second keys fastened to the axial support element and each arranged in a respective first or second through opening formed in the shell. The first key is mounted to bear against a first circumferential bearing surface of the first through opening while the second key is mounted against a second circumferential bearing surface of the second through opening opposite to the first circumferential bearing surface of the first through opening in a circumferential travel direction. The first key is mounted to bear against the second longitudinal bearing surface of the first through opening, while the second key is mounted against the first longitudinal bearing surface of the second through opening opposite to the second longitudinal bearing surface.

Composite material roller for high-temperature annealing

A packing structure according to the invention for a fluid contacting column forms a volume comprising an ordered arrangement of bundles of tubes of diameter ranging between 5 and 50 mm. The walls of the tubes comprise orifices which promote circulation and mixes fluids in the structure. The orifices are inscribed in rectangles whose sides range between 2 and 45 mm, and each one of the orifices extends over a surface area greater than 2 mm.

Packing structure for fluid containing column and manufacturing method

The invention relates to a packing structure () for a fluid exchange column, the packing structure defining an exchange surface for at least one down-flowing liquid phase that is to be put into intimate contact with at least one up-flowing gas phase, the structure including a volume formed by a plurality of rows of bundles of tubes (), each bundle having four tubes (-) respectively oriented along four directions (D-D) forming an angle relative to the axis of the structure, the plurality of tubes forming a plurality of passages opening out to the outside surface of the structure ().
