An apparatus and method for filtering molten metal (M), such as aluminum or an aluminum alloy includes at least one ceramic foam filter or any other type of filtration media such as porous tube or alumina balls disposed in a receptacle (12) for the molten metal (M). A vibrator vibrates at least one of the filter, the receptacle (12) or the metal and may be used to induce priming, filtering and/or drainage of the filter. The vibrator may be retrofitted to an existing filter system and may be adjustable in frequency and amplitude. The vibration may be continuous over a given period or produced in a single shock.

The pouring apparatus includes: a ladle including a nozzle and configured to store molten metal; a tilting mechanism configured to tilt the ladle so that a tapping position from the nozzle of the ladle is maintained at a constant position; and a radiation thermometer including a sensor head configured to output a signal related to a temperature at a measurement position and an amplifier configured to process the signal output by the sensor head, wherein the sensor head is disposed so that the measurement position is at the tapping position, and outputs a signal related to a temperature of molten metal in a molten metal flow at the tapping position.

A control method and apparatus for inhibiting slag entrapment in ladle (1) during continuous casting production. An optimal control model calculating unit (11) receives related signals and data sent by a ladle weight detector (4), a molten steel flow field detector (5), a slag detector (7), a sliding gate opening detector (9), and a process signal interface unit (10), performs calculation and analysis according to an optimal control model to obtain a corresponding optimal control strategy, and outputs the strategy to an electromagnetic brake (6) and a sliding gate controller (8) for slag entrapment inhibition control. Regarding the two processes where a vortex may be formed, by means of different optimal control strategies, which respectively inhibit or destroy the formation of a vortex, slag generation is postponed, and molten steel may flow out without bringing slag out, thereby reducing residual ladle steel and improving molten steel yield.

A tundish with improved flow characteristics for molten metal has an outlet in its base. The outlet is spaced longitudinally in the tundish from a pour zone. The pour zone is positioned to receive a stream of molten steel from a ladle. The outlet is provided with a refractory barrier at its upper end. A portion of the floor of the tundish circumferential to the outlet is provided with a refractory structure having an interior free volume. Structures within the tundish, such as a dam extending upwardly from the tundish floor between the pour zone and the outlet, or a well in the tundish floor surrounding the outlet, may be used to affect the flow of molten metal in the tundish.

A pouring facility includes a mold conveying device configured to convey a mold, a molten-metal discharging container configured to store waste molten metal, and a pouring machine movable on a conveyance path located between the mold conveying device and the molten-metal discharging container, the pouring machine being configured to tilt a ladle in a first direction to pour molten metal into the mold conveyed by the mold conveying device, and tilt the ladle in a second direction opposite to the first direction to discharge waste molten metal into the molten-metal discharging container.

The invention Ceramic Metal Riser Tube stalk is designed to countermeasure the problems caused by the use of conventional riser tubes. The subject matter uses metals and ceramics combination therefore achieving properties of both materials. The invention reduces safety risks of Riser tube replacement, down time, reduces losses caused by casting defects and it is economical to manufacture. Components of the subject matter can be reused for further economic benefits.

The present invention relates to the field of alloy-smelting facilities, and provides an aluminum-based ultra-thin launder. The launder has a body with a wall thickness of 12 mm to 25 mm. The body has a segmented structure, including a part of alloy in, a first launder, a second launder and a part of alloy out that are connected in sequence. The body of the launder provided in the present invention is lighter and thinner. The cost of production and use is reduced due to the significantly-decreased wall thickness and weight. The connection mode for components of the body is changed, which is beneficial to the replacement, and fundamentally lowers the risk of a repair material contaminating melted alloy.
