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.

A hearth roll includes a base roll, a thermally sprayed coating formed on the base roll, and a modified coating formed on the thermally sprayed coating. The modified coating is formed by modifying a part or the whole of a surface of the thermally sprayed coating by melting and solidification of the thermally sprayed coating, by irradiating a part or the whole of the surface of the thermally sprayed coating with an energy beam. The thickness of the modified coating is from 2 to 20 m, and the Vickers hardness HV of the modified coating is from 1.2 to 1.4 times larger than the Vickers hardness HV of the thermally sprayed coating.

The transport roller disclosed herein includes: an outer tubular member which is tubular and is made of a metal material; an inner tubular member which is provided inside the outer tubular member, is tubular, and is made of a ceramic material; multiple ring-shaped projections which each have a ring shape along an outer peripheral surface of the outer tubular member, are made of a metal material, and are supporting the heating target; and protection members which are formed in respective portions of the ring-shaped projections in contact with the heating target, and each include a ceramic coating containing a ceramic component.

A mobile removable hearth skid for a furnace and/or cooling chamber including: a base, the base including a top horizontal surface supporting a refractory platform which possesses a perimeter edge including a front perimeter edge, a rear perimeter edge, and at least two side perimeter edges. The rear perimeter edge and the at least two side perimeter edges form a continuous shoulder extending beyond the base perimeter edge. Also disclosed is a furnace and/or cooling chamber including a refractory lining with a continuous ledge at the bottom edges of the refractory linings mounted on the rear wall and the at least two side walls. A gap is formed by the furnace supports between a bottom surface of the ledge and a surface supporting the furnace supports. The shoulder and ledge form a removable refractory seal.

The invention relates to a charge carrier (10) for the defined arrangement of processed objects, the charge carrier comprising, as components, at least a support grid (11) having a plurality of receiving elements for receiving the objects, the receiving elements being connected to the support grid in a form-fitting manner via a plug-in connection, wherein the receiving elements are designed as adapters (25) for the positioned individual reception of the objects, the adapters being received in adapter receptacles of the support grid so as to be arranged in a positioned manner.

A continuous heating furnace (200) includes a conveyance body (210) stretched in an endless shape and configured to convey a burning target, a furnace main body (212) partially or entirely surrounding the conveyance body to form a burning space, and a roller (214) configured to support a portion of the conveyance body in the furnace main body. The continuous heating furnace (200) further includes one or more closed gas heaters having an introduction hole configured to introduce a fuel gas into a heater main body, a combustion chamber in which the fuel gas is combusted, a discharge section to which an exhaust gas is guided, a radiation surface heated by the exhaust gas flowing through the discharge section or combustion in the combustion chamber and configured to transfer radiant heat to a burning target, and an exhaust hole configured to exhaust the exhaust gas that heats the radiation surface to the outside of the heater main body, and disposed in the furnace main body, and an exhaust pipe (216) in communication with the exhaust hole of the closed gas heater and through which the exhaust gas is guided. In addition, the exhaust pipe enables heat exchange between the exhaust gas flowing through the exhaust pipe and the roller.

The present invention relates to a water-cooled handling roll (100) for handling a load (50), in particular a thin slab, in a furnace for temperature heating, maintaining and for buffering, arranged between casting and roughing, in a continuous casting and rolling process for thin carbon steel slabs. The roll (100) comprises a first internally hollow shaft (110), which is coated by an insulating and/or refractory material and a plurality of wheels (25) connected in stably fixed manner to an outermost surface (111) of the first shaft (110) to handle and support the load (50). According to the invention, the roll (100) also comprises a second shaft (120) arranged within an inner cavity of the first shaft (110) in position coaxial to the first shaft (110) and so as to define a gap (30) between the first shaft (110) and said second shaft (120). The roll (100) further comprises cooling water circulation means housed at least in part within said second shaft (120).

A protective and abradable coating composition is suitable for application on rolls and more particularly for application on conveyor rolls. The abradable coating is suitable for use in high temperature applications. Rolls incorporating the coating may be produced and used according to disclosed processes and procedures. Application of the composition to rolls reduces corrosion by aluminium melt, and enables the removal of built-up substances by friction. The life time of the roll is thereby increased.
