Abstract
The invention relates to an uncooled furnace roll (1) for transporting continuously cast material from a continuous casting facility, and to a method for the production of such a furnace roll. The furnace roll (1) comprises a cylindrical roll body (2), conical end pieces (6) being attached to the end faces (8) of the roll body. Inside the furnace roll (1) a hollow space (4) is provided in the region of the roll body (2) and/or in the region of at least one conical end piece, said hollow space being sealed off from the atmosphere (A) and being placed under vacuum.

An uncooled furnace roll (1) for transporting continuously cast material from (or in) a continuous casting facility comprised of
- a cylindrical roll body (2), and
- conical end pieces (6) which are attached to the respective end faces (8) of the roll body (2),
- characterized in that
- inside the furnace roll (1) a hollow space (4) is provided in the region of the roll body (2) and/or in the region of at least one conical end piece (6), said hollow space being sealed off from the atmosphere (A) and being under vacuum, so that vacuum means of thermal insulation are provided, at least for the roll body (2) and/or the conical end piece (6).
A method for producing an uncooled furnace roll (1), characterized by the following steps:
- preparing a cylindrical roll body (2);
- preparing at least one conical end piece (6);
- and
- attaching the conical end piece (6) to an end face (8) of the roll body (2), such that thereby a hollow space (4) which is formed inside the furnace roll (1) in the region of the roll body (2) and/or in the region of the conical end piece (6) is closed off so as to be sealed against the atmosphere (A), wherewith the hollow space (4) is placed under vacuum.
