A system for conditioning stucco particulate material includes a vessel having separation chamber in communication with a holding chamber having a holding volume therein. The conditioning system includes the holding volume sufficient to condition the stucco particulate material therein and/or a control system configured to delay discharge of the stucco particulate material from the holding chamber. The system for conditioning stucco particulate material is configured to increase residence time of the stucco particulate material in the holding chamber to promote calcining conditioning therein.

A method of fluxing or degassing a molten metal residing as a bath in a furnace. The bath of molten metal includes a bath surface height and the method provides at least one rotating impeller in the molten metal bath to initiate a flow of the molten metal. The flow in the molten metal results in elevating a portion of the molten metal above the bath surface height where at least one of a fluxing agent and an inert gas is introduced into the elevated portion of the molten metal.

A detection wave from a transmitting/receiving means is guided to the interior of a blast furnace via an antenna and a reflecting plate, and when a reflected wave from the surface of a loaded material is reflected by the reflecting plate and received by the transmitting/receiving means, the reflecting plate is rotated together with the antenna, or the reflecting plate is rotated additionally, and the surface profile of the loaded material is measured by scanning the surface of the loaded material in a linear manner or a planar manner during the turning of a chute or for each prescribed turn of the chute. A deposition profile is obtained on the basis of this surface profile and is compared to a predetermined theoretical deposition profile, and the chute is controlled so as to correct the error with respect to the theoretical deposition profile and then which new loaded material is introduced.

Melting plant having a melting chamber which by way of a gas protection hood is separated from the environment, wherein the gas protection hood or another part of the melting chamber encasement has a lead through in which an electrode rod for moving an electrode to be melted is guided in a gas-tight manner by way of a sealing means. Hydraulic or pneumatic equalisation means, for exerting on the electrode rod equalisation forces which are in a proportional correlation with the gas pressure prevailing within the melting chamber are provided so as to compensate for the gas-pressure forces acting on the electrode rod.

Devices, systems, and methods for pressure-regulated melting are disclosed. A vessel includes a solids inlet, a fluids outlet, a cavity, and a melting device. Solids enter the vessel through the solids inlet. The cavity has an internal pressure. The solids inlet has a reducer that produces a first back pressure on the solids in the solids inlet. The melting device heats the vessel, the contents of the vessel, or a combination thereof. The heating rate of the melting device is matched to the feed rate of the solids such that the solids are melted directly to a product liquid at the internal pressure. The product liquid passes through the fluids outlet through a restriction that maintains the internal pressure in the cavity.
