ABSTRACT:
A portable dross processing system has a support frame with a base and an upper support. A pair of wheels are mounted to the base, and a steering wheel can be pivotably mounted to the base. A dross receiving crucible is mounted in a crucible frame which is pivotably mounted to the upper support. The crucible has a sidewall and a bottom having a port. The crucible may be formed from a mounting rim of steel plate to which a metal mesh reservoir form is attached. The mesh is then covered with moldable refractory cloth, over which a ceramic wash is applied. A finishing wash is applied to the crucible interior. Preheated dross is loaded into the crucible while in a dross loading position. The dross is preferably mixed with an exothermic compound and stirred to promote coalescence of the entrapped metal. After the molten metal forms a pool in the bottom of the crucible, the port is opened to drain the metal. The port can be opened by a closure plate slidably engaging a pair of channels and supporting a port plug. A metal collection pan below the crucible accepts the metal. A handle affixed to the support frame aids in maneuvering the system. The crucible is pivoted to a spent dross removal position to deposit the spent dross into a container such as a drum.
