An apparatus may comprise a degassing system and a treatment station. The treatment station may comprise a shell, a refractory disposed in the shell, and insulation disposed between the shell and the refractory. The refractory may comprise a first plurality of slots, a second plurality of slots, and a trough. The first plurality of slots may be upstream from the degassing system and the second plurality of slots may be downstream from the degassing system. A first skim brick may be slideably disposed in a first one of the first plurality of slots and a second skim brick may be slideably disposed in a first one of the second plurality of slots. A first filter may be slideably disposed in a second one of the first plurality of slots and a second filter may be slideably disposed in a second one of the second plurality of slots.
