    摘要: A process for the econimic recovery of metallic fractions generated during operation of a cupola furnace comprises the steps of the separating filter dust containing metal fractions from an off-gas stream and recirculating the metal fraction back to the cupola furnace for combustion with additional feedstock so as to enrich the metallic concentration of the filter dust to a level where economic recovery of the metallic fraction can occur.

    摘要: A ceramic filter for filtering molten iron is disclosed. The ceramic filter is made from a high-melting ceramic material having an open-celled foam structure, a variable bulk density in different portions of the filter, and at least one afflux surface. In order to filter molten iron efficiently, the ratio of filter surface to filter volume should be in the range of about 0.0003 to 9 m.sup.2 /cm.sup.3, the specific filter resistance should be in the range of about 0.1 to 0.9 bar-cm at a flow rate of 5 m.sup.3 /hour, and the pressure loss .DELTA.p across the filter should depend on the specific resistance .rho., the filter length, and the surface area of the afflux plane F in accordance with the relationship: ##EQU1## A method for filtering molten iron using this ceramic filter is also disclosed. In this method, the ceramic filter is located near the point in the casting system where the molten iron has its greatest kinetic energy. The molten iron is first caused to flow tangentially by the afflux plane of the ceramic filter and then is deflected to create turbulence directly before the afflux plane of the filter.

    摘要: A casting furnace is fed an inert gas under pressure through a feed line with the pressure being regulated by a melt level control device. When the pressure is reduced, the inert gas is exhausted from the casting furnace by an exhaust line, the feed line having a check valve to prevent gas which is contaminated by magnesium from entering the feed line. An oxidizing gas, preferably pressurized air, is periodically fed into the exhaust line by an oxidizing gas line for cleaning the drain line and the pressure-controlling aperture therein by oxidizing the magnesium.
