Methods and systems are provided for treating oxide scale on the surface of a metal object. In one embodiment, a system temperature control apparatus controls the temperature of metal object's surface to an application temperature below the Leidenfrost temperature point of an alkali metal hydroxide aqueous conditioning solution. An application apparatus wets the metal object's surface at the controlled temperature with a thin layer of the solution that engages the oxide scale, and a heating apparatus heats the wetted surface to a final conditioning temperature above a melting point of the alkali metal hydroxide by an additional value selected to effect conditioning of the oxide scale at a reasonable but not excessive rate by the melting alkali metal hydroxide reacting with the oxide scale. The system terminates additional conditioning to prevent creation of additional oxide scale beyond the conditioned depth.

Metal surface scale conditioning

A method and device for removing particulate matter from a liquid medium, especially a molten salt bath. The structure includes a device for capturing and removing particulate matter from a liquid medium. In operation, the device is inserted into the liquid having the particulate matter, with a particulate matter collector in the particle collecting position. An agitator circulates the liquid having the particulate matter therein. A portion of the particulate matter is collected in the particulate matter collector during the circulation. Thereafter, the circulation is ceased and the device is removed from the liquid with the particulate matter in the particulate matter collector. The device is moved to a discharge position, and the particulate matter collector is moved to a particle discharge position to discharge the particulate matter.
