Diffusion article
A diffusion component for impregnating molten steel with a gas includes a barrier having a first side and a second side, a through-hole formed within the barrier, the through-hole connecting the first side to the second side, and a porous element arranged within the through-hole such that the flow of molten steel passes over the porous element. At least one flow disrupter is arranged relative to the porous element and configured to promote non-laminar flow of molten steel passing through the through-hole.

PROCESS TO MAKE A CERAMIC FILTER FOR METAL CASTING
A ceramic foam filter system includes a filter body having multiple tortuous path channels through the filter body to filter a molten liquid. A filter holder configuration defining a canister in a runner passage receives the filter body. An upstream end of the filter body receives the molten liquid having multiple inclusions. A predominant portion of the inclusions are larger than the multiple tortuous path channels and are trapped against the upstream end of the filter body. The multiple tortuous path channels are sized to trap a predominant portion of multiple oxides within the molten liquid as trapped oxides within the filter body. A filtered molten material having the multiple inclusions and the multiple oxides removed is directed from the multiple tortuous path channels as a discharge flow to exit at a downstream end of the filter body.

MOLTEN METAL PURIFICATION DEVICE
A molten metal purification device for purifying molten metal flowing through a flow body having a flow path formed by a pair of opposed side walls and a bottom wall. The device includes internal and external members provided inside and outside the flow body, respectively. The internal member includes an electrode body provided inside the path made of a conductive member and has a pair of opposed electrodes provided in the path where current flows across the electrodes through the molten metal and a non-conductive filter. The external member is configured as a magnetic field device having an upper surface side magnetized to an N or S pole and disposed below the flow body. Lines of magnetic force coming out from the N pole or entering the S pole intersect with the current to generate Lorentz force for driving the molten metal along a flowing direction in the path.

Filter handling tool
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.
Method of casting articles from aluminum alloys
The invention relates to the field of aluminum metallurgy and can be used to produce ingots from high quality aluminum alloys when manufacturing aerospace and automotive products. The use of this invention relates to the technology of secondary modification. The method of casting products from aluminum alloys includes the following stages: a) aluminum melt preparation in the alloying furnace; b) addition alloy introduction into melt; c) degassing of the aluminum melt containing the addition alloy; d) addition alloy re-introduction; e) filtration of the aluminum melt obtained at stage d) and f) feeding the filtered melt into the crystallizer. It ensures the improved effectiveness of the aluminum melt modification with addition alloys without additional constructional changes in existing lines for aluminum ingot casting. It allows reducing the alloy modification costs, decreasing the grain in resulting alloys and improving plastic and mechanical properties of the obtained cast ingots and their products.
