Abstract: According to one aspect of the present disclosure, a method of priming a ceramic filter element for removal of solid inclusions from liquid metal is provided. The filter element is contained in a filter box and at least two separate inductors are placed on opposed sides of the filter element. The method includes the steps of a) applying an excitation current to the inductors, b) adding sufficient liquid metal to cover an upstream side of the filter element, c) allowing the current induced in the liquid metal by the inductors to create Lorentz forces which press upon and stir the liquid metal such that the liquid metal is forced into the ceramic filter element, hence priming the filter element, and d) discontinuing the excitation current once a predetermined degree of priming has been obtained.

Abstract: A molten metal filter box. The filter box includes a filter housing provided in a flow path for molten metal. A horizontal partition is disposed within the filter housing and has at least one filter receiving passage. A filter medium in the shape of a substantially flat plate is positioned within the filter receiving passage and below an inflow path of the molten metal. The filter medium includes a hole. A filter handling tool is disposed within the hole. The filter handling tool can optionally include a handle secured to the molten metal filter box to suspend the filter medium. Advantageously, the filter medium can be removed by grasping the filter handling tool and removing the filter medium.

Abstract: An electromagnetic device for pumping, circulating or transferring non-ferrous molten metal has a duct made of a refractory material with a first aperture at a first end of the duct and a second aperture at a second end of the duct. The duct conveys a body of non-ferrous molten metal between the first and second apertures. The duct encloses the body of non-ferrous molten metal between the first and second apertures. The duct has opposing first and second external side surfaces. A first inductor assembly extends adjacent to the first side surface. The first inductor assembly comprises a plurality of inductors arranged along a length of the duct adjacent to the first side surface. An electronic circuit generates direct current pulses that energise each inductor of the plurality of inductors in a sequence, so as to generate a moving magnetic field within the body of non-ferrous molten metal which propels the body of non-ferrous molten metal along the duct.

Abstract: An apparatus and method are described for effectively priming a non-electrically conductive filter for removal of solid inclusions from liquid metal. In one embodiment, the ceramic filter media is surrounded by a low frequency induction coil (1-60 Hz) with its axis aligned in the direction of the net metal flow. The coil is positioned to enhance the heating of any metal frozen onto, or in the pores of, the filter element. In one embodiment, the coil is positioned in order to generate Lorentz forces, which act to cause heated metal to impinge on the upper surface of the filter element, enhancing the priming action. Once a filter equipped with such a coil has been primed, it can be kept hot or reheated, and subsequently reused during several batch tapping sequences.

Abstract: Implementations of the present disclosure include methods, systems, and computer-readable storage mediums for model-to-model transformation including actions of providing a source meta-model, the source meta-model having a plurality of classes and one or more references, receiving first user input to a graphical editor, processing the first user input to provide a plurality of class modules and one or more reference modules, each class module corresponding to a class of the plurality of classes and each reference module corresponding to a reference of the one or more references, automatically generating transformation code based on the plurality of class modules and the one or more reference modules, receiving a source model, the source model being provided based on the source meta-model and being provided in a computer-readable file that is stored in memory, and generating a simulation model based on the source model and the transformation code.
