A melting pot includes a pot body and a float salvaging apparatus. The pot body is provided with a melting chamber having an open upper end. The float salvaging apparatus includes a hanging bracket, a bearing plate, a rotating plate and a drive assembly configured to drive pivoting of the rotating plate. The hanging bracket is disposed above the melting chamber. The rotating plate is pivotably disposed on the bearing plate, and the bearing plate and the rotating plate are provided on the hanging bracket between an initial position and a first salvaging position in a manner of moving up and down. The drive assembly is connected to the rotating plate.

There is disclosed a furnace (10), a fluid feed component, a fluid reforming system, and a method of reforming a fluid (20). The furnace (10) comprises a vessel (12) that defines a chamber (14) for holding a body of liquid (16). A fluid inlet (18) is provided for introducing a fluid (20) into the chamber (14) below a level (22) of the body of liquid (16) to cause the fluid (20) to interact with the liquid (16) and to migrate therethrough towards an outlet (24) for discharging a product (26) of the interaction from the chamber (14). A liquid circulation passage (28) is implemented, having a weir (30) which is operatively located near the level of the body of liquid (16), and a port (34) which is located remote from the weir (30) and in fluid (20) communication with the fluid inlet (18) so as to enable the liquid (16) to flow over the weir (30) through the liquid circulation passage (28) and through the port (34).

A slag door for a melting furnace for the production of steel is suitable to be associated with an aperture provided in a lateral wall of the melting furnace and to cooperate with a slag channel provided inside the melting furnace itself.

A melting work device and a melting work method by which work can be easily performed on a melting furnace without a worker approaching the melting furnace. A melting work device performs work on a melt obtained by melting a material in a melting furnace. The melting work device has a drive mechanism; and a plurality of work tools that are operated by the drive mechanism; wherein the drive mechanism is able to move the work tools in an arbitrary direction at an arbitrary location above the melting furnace.

A slag door arrangement (10) for a metallurgical furnace (1) includes a furnace vessel (2) with a slag tunnel (8) having a rectangular opening cross section extending laterally through the furnace vessel (2). A pivoting movement of the slag door about a horizontal pivoting axis and a lifting movement of the slag door in a direction perpendicular to the horizontal pivoting axis are independent of each other. A method for cleaning a slag opening of such a metallurgical furnace (1) includes pivoting the slag door to perform a cleaning movement from a position of the slag door in the slag tunnel near the interior of the furnace towards the outside of the furnace out of the slag tunnel at controllably different distances (clearances) from the bottom of the slag opening or of the slag tunnel.

A method and an installation (10) for removing slag allows both slag removal and metal recovery from slag (60′) to be performed quickly and easily. The risk of slag fires is reduced.

A skim tool and method for removing impurities from molten alloys in furnaces generally includes a collection portion and an arm. The collection portion has an interior and a blade member having a plurality of apertures configured to capture impurities during application and direct the impurities into the interior. The skim tool further includes a conduit having a first end with an inlet and a second end having a plurality of fingers that extend in various directions along the front side of the blade member. Each of the fingers define an outlet end that are in fluid communication with the inlet. The inlet for receiving a source of nitrogen to be blown through the conduit into the molten metal in the form of a gas.
