A melting apparatus for steel production includes a support structure to support a shell for the production and tapping of steel, and a source or zone for the emission of fumes resulting from the tapping of the steel from the shell. The melting apparatus also includes a tapping hood integrated into the support structure and provided with a suction mouth positioned directly above the zone for the emission of fumes, the shell is provided with a bottom wall in which an E.B.T. is provided for tapping the steel.

Apparatus for continuously conveying and pre-heating a metal charge inside a container of a melting plant, includes at least a channel for conveying the metal charge, at least a hood disposed above the conveyor channel defining a tunnel and/or an expansion chamber, inside which at least part of the fumes exiting from the container advance, and apertures made in cooperation with lateral walls of the conveyor channel to discharge the fumes. The conveyor channel includes an activator that divert the fumes and/or delimit the zone occupied by the metal charge of the conveyor channel, and that cooperate longitudinally with at least part of the conveyor channel.

A refractory component for forming a refractory lining includes a refractory brick, and a support member having at least one surface fixed to the refractory brick.
