Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a take stainless steel group to solid fixed ring's of formula hearth roll as shown in fig. 1-3, including DS spindle nose 1, roll body 2, group to formula fixed establishment 3 and TS spindle nose 4, the one end of roll body 2 is equipped with DS spindle nose 1, the other end of roll body 2 is equipped with TS spindle nose 4, the surface symmetry formula of roll body 2 is equipped with group to formula fixed establishment 3.

The paired fixing mechanism 3 comprises a first fixing ring 31, a second fixing ring 32, a mounting edge 34, a locking bolt 35 and a locking nut 36, wherein the first fixing ring 31 and the second fixing ring 32 are all of an integrated structure made of stainless steel materials; the solid fixed ring of 31 of first solid fixed ring and the solid fixed ring of second 32 both ends side surface all is equipped with installation limit 34, sets up the solid fixed ring of 31 of first solid fixed ring and second 32 both ends's installation limit 34 is the integrated structure that steel construction material welded and formed.
