The disclosure relates to a method for operating a cooling chamber in a strand guide device and the strand guide device 10 as such. The strand guide device serves to deflect a freshly cast strand, typically made of metal, into the horizontal. During the deflection, the cast strand passes through a cooling chamber 1 inside the strand guide device 2, in which it is sprayed with a coolant 33, with the formation of steam 5. The steam forms at least a steam-air mixture 5 with sucked-in secondary air, which is sucked out of the cooling chamber by a suction device 20. In particular, in order to reduce the pollutant content of the sucked-in and sucked-off steam-air mixture 5 and its emission into the environment, the present invention provides for pollutants, primarily dust, located in the steam-air mixture 5 by a separator 6, 6 to deplete.

A casting system includes a casting surface; a rim area disposed on the casting surface or associated therewith; a heat resistant impermeable diaphragm having an edge area. The diaphragm covers a portion of the casting mold when it is positioned on the surface so as to form a space defined by at least a base constituted by the surface, and at least a casting face constituted, at least partially, by the diaphragm; a sealing arrangement for sealingly engaging the rim and edge areas, thereby sealing the space; an outlet for withdrawing gas from the space; a heat resistance coefficient of the diaphragm is such that it can melt when coming in contact with the molten material. The diaphragm covers an area larger than that through which molten material is case so that, when the space is sealed, vacuum application causes the diaphragm to adhere to a portion of the mold.

A jetting device includes: a fluid chamber connected to a nozzle and containing an electrically conductive liquid to be jetted out through the nozzle; a magnetic field generator arranged to create a magnetic field in the fluid chamber; a pair of electrodes contacting the electrically conductive liquid in the fluid chamber; and a controller arranged to control a flow of an electric current through the electrodes and the electrically conductive liquid. The magnetic field generator is arranged to create a rotating magnetic field in the fluid chamber.

A method for casting cast parts in which a casting mould is provided. The casting mould is enclosed in a housing, forming a filling space between an inner surface section of the housing and an associated outer surface section of the casting mould. The filling space is then filled with a free-flowing filling material and molten metal is poured in the casting mould. As a consequence a binder of the mould material begins to vaporise and combust disintegrating the casting mould. During the filling of the filling space, the filling material has a minimum temperature, starting out from which the temperature of the filling material rises, to beyond a boundary temperature at which the vaporising binder ignites and combusts.

A die casting mold evacuation valve assembly features a two-part valve casing. Machined in the front casing part is an evacuation duct closable by an evacuation valve. Housed in the casing is an actuator for actuating a valve piston of the evacuation valve. The actuator includes a casting material actuated force transducer and a force transmission member for transmitting the closing movement of the force transducer to the valve piston of the evacuation valve. The actuator features in addition a stacked spring assembly for returning the actuator and/or force ejecting the riser. The front casing part is provided with a sleeve surrounding at least a head part of the valve piston and/or a further sleeve surrounding at least the head part of the force transducer. Both sleeves are harder than the front casing part.

A method of neutralizing an amine gas odor in a cold box process, and an amine gas generator using the method are disclosed. The method includes: making molding sand by mixing sand and forming resin; putting the molding sand into a mold; hardening the molding sand by injecting an amine gas into the molding sand in the mold; and removing an amine gas odor remaining in the mold by injecting an amine gas odor neutralizer into the mold. Accordingly, it is possible to inject an amine gas odor neutralizer in casting of a core or a mold in order to reduce the amine gas odor that remains and leaks through a gap of a mold in the casting. Further, an odor neutralizer is immediately injected simultaneously with discharging of an amine gas, so it is possible to simply remove an odor.
