Abstract: A method of transferring molten metal from an upper source reservoir to a lower reservoir using an inverted substantially U-shaped conduit (3) having a curved section (4) and two leg sections (7, 8). Molten metal is drawn up into the upper, generally shorter leg (7) of the conduit to partially fill the conduit. The level of vacuum in the conduit is then controlled to prevent the curved section of conduit completely filling with molten metal and provide a controlled and/or constant flow of molten metal to the lower reservoir (2).

Abstract: The invention relates to an apparatus and method for regulating the flow rate of a liquid furnace product. The apparatus comprises a heat exchange jacket (10) surrounding a conduit (9) through which liquid furnace products flow. The heat exchange jacket (11) removes sufficient heat from the conduit and product flowing therein to cause a shell of solidified product to form on the internal surface of the conduit. The flow rate in the conduit is controlled by regulating the coolant flow through the heat exchange jacket and consequent shell thickness.

Abstract: A device for liquid pumping comprises a pump chamber (21) arranged to receive a subportion of the liquid to be pumped. The pump chamber is provided with means for cyclic variation of the pressure in the pump chamber between an overpressure and a depression with regard to the pressure in the chamber (17) where the main portion of the liquid is. The pump chamber (21) is further provided with an input opening (22) and an output opening (23). The input opening (22) has a substantially lower flow resistance in the direction into the pump chamber (21) than in the opposite direction, and the output opening (23) has a substantially lower flow resistance in the direction out of the pump chamber than in the opposite direction, so that with a depression in the pump chamber a larger liquid quantity is sucked into the pump chamber through the input opening (22) than through the output opening (23) and that with an overpressure in the pump chamber a larger liquid quantity is forced out through the ouput opening (23) than through the input opening (22). Due to this fact a net liquid quantity can be sucked in through the input opening and forced out through the output opening. The device makes it possible to pump many types of liquids, for example molten metal, without the use of movable valves.

Abstract: For the purposes of transferring a predetermined amount of liquid metal from a vessel (1) containing a molten metal bath (2) into a receiving container (3), there is provided a discharge flow pipe (4) which has a refractory lining and which is in the form of an inverted U or V with two downwardly pointing limbs (5, 6) of which the first has an intake opening and the second has an outlet opening for the liquid metal, which outlet opening can be gas-tightly closed by a closure means. Provided in the upper region of the discharge flow pipe (4) is a pipe connection (14) which has a refractory lining and which can be communicated with a vacuum means (19, 20). The discharge flow pipe is dipped with its first limb (5) into the molten metal bath (2) and the liquid metal is removed on the basis of the principle of a liquid siphon.

Abstract: Guide troughs for leading molten products tapped from blast furnaces or electric furnaces or the like. A lengthy trough body (1), formed in one block with monolithic refractories, is provided with hook-engaging means in order for the body to be lifted and transported. The hook-engaging means comprises supporting pipes (2) which are laid longitudinally in the upper portion of the body on both sides thereof; supporting transverse members (3) which are disposed in an appropriately spaced-apart relationship to interconnect the supporting pipes on both sides of the trough body; and cut-out portions (4) provided in the trough body at suitable locations to expose the supporting pipes (2) to be engaged by hooks. The fact that the trough body has such stout supporting means and hook-engaging means which does not project from the upper surface of the trough body as the suspension plates in the conventional guide trough of this type, allows the following advantages to be obtained. Namely, the hook-engaging means is protected against radiant heat and splashing from high temperature molten products flowing through the trough. This greatly enhances safety during transportation. In addition, as there are no objects projecting from the upper surface of the trough body, the guide troughs can be stored by stacking. This permits a reduction in storage space.
