An improved permeable bottom crucible is provided. The permeable bottom crucible is particularly suitable for degassing molten metal. The permeable bottom crucible comprises a refractory ceramic body comprising walls and an integral bottom wherein the integral bottom has a porous portion. The porous portion has a porosity which is higher than a porosity of the walls. Inductive coils are around the refractory ceramic body. A plug is arranged to disperse gas through the porous portion.

The method according to the invention enables a facility having a rather reduced dimension, for incinerating to be used, melting and vitrifying mixed waste (30) introduced into a reactor (10), by means of a basket (18) in turn passing through an air lock (12). Plasma torches (14) burn all waste (30) contained in the basket (18). The waste is then lowered in a melting bath of a furnace (20) with an inductor (24) including a crucible-forming container (23). A combustion gas treatment train completes the facility. The furnace (20) can be dismantled, after a series of treatments of several baskets (18) of waste (30) for disassembling the crucible-forming container (23) from the furnace (20). Application in treating different radiologically contaminated and/or toxic mixed waste.

The present invention relates to a process for measuring the temperature of a fusion furnace, in particular for the production of superalloy components with directional (DS)/monocrystalline (SX) grain structure by means of a lost wax precision casting process by means of a temperature probe, said fusion furnace comprising a melting chamber, a thermal chamber in connection with said melting chamber, and an extraction chamber in connection with said thermal chamber, a valve interposed between said two melting and thermal chambers, said probe comprising a thermocouple for high temperatures, a support element for positioning the temperature probe in the melting chamber of the furnace, displacement and measurement means of the position of the thermocouple for displacing and measuring the position of the thermocouple within the thermal chamber of the furnace, control device to actuate and control said displacement and measuring means.
