Abstract
A portable dross pressing apparatus utilizes a frame which may be made portable by wheels, by forklift tubes or the like. A press head is mounted to an upper portion of the portable frame and a drive means is used to force a skim pot upwardly into juxtaposition with the press head wherein dross within the skim pot may be compressed between the skim pot and the press head. The pot and/or head may contain ribs which may or may not mate. The pressing components may be made of cast steel or of a refractory material, such as ceramic. A pot of refractory material would be constructed over a metal shell for reinforcement. Preferably, the skim pot and sow mold are mounted within a traveling frame which is movably mounted to the portable frame. The skim pot may be provided with an automatic dumping mechanism and the sow mold may be mounted on a slide drawer mechanism. In a preferred embodiment, the skim pot is provided with means for preheating which may either be a gas burner or electrical resistance heaters. In the refractory skim pot, electrical resistance heaters may be mounted within the refractory material. In another aspect, skim pots may be constructed with a removable insert drain …
