Support device for radiant tubes

A support device for a radiant pipe, usable in thermal treatment furnaces, for continuous lines for galvanising and annealing strips or plates made of metal sheet and/or other products made of steel and/or other metals or for revamping pre-existing furnaces, comprising:

• a support for radiant pipe or shank and a furnace-side support or socket,
• wherein said support for radiant pipe or shank comprises at least one outer surface, directed during use towards the furnace-side support or socket, an inner surface and a thickness, wherein said thickness corresponds to a distance between the inner surface and the outer surface,
• wherein said furnace-side support or socket comprises at least one first surface and one second surface, the latter directed during use towards the support for radiant pipe or shank, and a thickness, wherein said thickness corresponds to a distance between the first surface and the second surface,
• at least one rotary means and at least one seat for housing said at least one rotary means, wherein said housing seat has a circular opening, wherein said at least one rotary means is positioned by means of said at least one seat within said support for radiant pipe or shank and/or said thickness of said support for radiant pipe or shank and/or is positioned within said furnace-side support or socket and/or said thickness of said furnace-side support or socket, so that said at least one rotary means determines the support of said support for radiant pipe or shank on said furnace-side support or socket and a rolling friction between said support for radiant pipe or shank and said furnace-side support or socket,
• wherein said at least one rotary means comprises a substantially spherical element,
• said at least one rotary means being rotatably constrained within said at least one seat, wherein said at least one rotary means projects from outer surface of the shank and/or from the second surface of the socket and projects from said opening of said housing seat by a distance and wherein between said at least one rotary means and said at least one housing seat, a gap is present during use that allows the rotation of said at least one rotary means and the maintenance thereof within said at least one housing seat, wherein said at least one seat is shaped in a manner such to house said at least one rotary means and constrain said at least one rotary means within said shank and/or socket, simultaneously allowing rolling along an entire surface of said at least one rotary means,
• wherein said at least one seat comprises a first zone or cavity having a shape corresponding to that of the at least one rotary means.

• wherein said at least one rotary means comprises a substantially spherical element and wherein each of said at least one housing seat houses a single substantially spherical element,
• said at least one rotary means being rotatably constrained within said at least one seat, wherein said at least one rotary means projects from outer surface of the shank and/or from the second surface of the socket and projects from said opening of said housing seat by a distance and wherein between said at least one rotary means and said at least one housing seat, a gap is present during use that allows the rotation of said at least one rotary means and the maintenance thereof within said at least one housing seat, wherein said at least one seat is shaped in a manner such to house said at least one rotary means and constrain said at least one rotary means within said shank and/or socket, simultaneously allowing rolling along an entire surface of said at least one rotary means,
• wherein said at least one seat comprises a first zone or cavity having a shape corresponding to that of the at least one rotary means and said at least one seat comprises an insert installed on said support for radiant pipe or shank and/or said furnace-side support or socket.
