    摘要： Separating volatile impurities from AlCl.sub.3 by supplying impure AlCl.sub.3 into a molten salt bath of a gas separation compartment in an electrolysis cell. The impurities are removed from the compartment and molten salt bath containing dissolved AlCl.sub.3 is carried under a partition into a chamber where the AlCl.sub.3 is electrolyzed. In a preferred embodiment, desublimation is avoided by supplying AlCl.sub.3 to the bath as a gas rather than in solid form.

    摘要： The shot sleeve of the invention is used in a die casting machine and defines a bore for containing molten metal to be injected into a die. At least one passageway disposed generally parallel to the bore for containing a first fluid having a fluid temperature and a fluid flow rate is provided, whereby substantially uniform temperatures can be maintained across the width of the shot sleeve by controlling the fluid temperature of the fluid flow rate or both the fluid temperature and the fluid flow rate. A die casting machine and an associated method are also disclosed.

    摘要： A molten metal treatment furnace (10) with metal treatment and level control includes a heating chamber (12) for containing and heating a supply of molten metal (60), a pump (22) connected to the heating chamber (12), a molten metal treatment chamber (16, 18) located at the outlet of the pump (22), and a dosing chamber (40) located downstream and in fluid communication with the molten metal treatment chamber (16, 18). A trough (44) is connected to the dosing chamber (40) for supplying the molten metal (60) to a downstream process. A molten metal level sensor (66) is located in the dosing chamber (40). The pump (22) is a variable speed pump having a pump inlet (24) connected to the heating chamber (12) and configured to pump the molten metal (60) through the furnace (10) during operation. The molten metal level sensor (66) is connected to the pump (22) for providing a pump speed control signal to the pump (22). The molten metal level sensor (66) is configured to monitor the level of the molten metal (60) in the dosing chamber (40) and maintain a preset level of the molten metal (60) in the dosing chamber (40) by controlling the speed of the pump (22) with the pump speed control signal.

    摘要： The fill chamber bore of a die-casting machine is lubricated and prepared for casting by inserting an elongated member into the die-end of the bore while spraying with lubricant. During withdrawal of the elongated member, a conical spray of gas directed toward the die-end drys the lubricant and sweeps vapor and flash, or solder, out of the die-end. The elongated member is preferably a flexible carrier which is guided between the bore and a path between the open die halves lateral to the bore. The lateral path is perferably defined by a tubular member supported by a vertical carriage mounted on a vertical mast for alignment of the flexible carrier with the fill chamber bore when the dies are open. The vertical mast can be mounted on a horizontal carriage moveable along a horizontal bore to preclude interference with normal operation of the die-casting machine. The flexible carrier can be housed in a arcuate chamber pivoted on the side of the fixed platen and swung between the open dies to align the flexible carrier with the fill chamber bore.

    摘要： A vacuum die-casting machine has a sprue cavity with sufficient depth facing the shot cylinder that the shot cylinder piston can easily crush with a pressure of less than 1000 psi the thin cylindrical shell of solidified metal which develops into the biscuit, and continue to advance after the die cavity becomes fried with molten metal to inject additional molten metal into the die cavity to make up for shrinkage porosity as the cast part cools. The runner through which the molten metal passes from the sprue cavity into the die cavity has generally spherical reservoirs adjacent circular gates to further assure the supply of the additional molten metal to make up for shrinkage in the part. In addition, the piston can be oil cooled steel to delay formation of the biscuit.
