Abstract
800,311. Extracting refractory metals. NATIONAL LEAD CO. June 5, 1957 [June 22, 1956], No. 17940/57. Addition to 758,763. Class 82(1): In a process for the production of a refractory metal compact by reacting a halide of the refractory metal and a reducing metal in a fused salt bath, employing a ram-type reactor as described in the parent Specification, the seal of frozen salt which surrounds the compact and retains it in the. reactor is melted sufficiently to enable the compact to be removed from the reactor. As shown, the compact is formed at the lower end 12 of the reaction vessel by pressure exerted by an upper ram and by ram 13 at the exit of the vessel. During the reaction, a seal of frozen salt is maintained between the compact and the vessel by cooling coil 30 and by coolant circulated through the coil of copper tubing 26. For removal of the compact, an alternating current from alternator 27 causes the coil 26 to act as an induction heater and the salt seal is melted thereby enabling the compact to be removed by lowering ram 13. The coil 26; which comprises a number of turns of soft copper tubing 28, is wound on an insulating material, such as a moulded mica composition 32 mounted on asbestos paper 31 wound on to the surface of the reaction vessel, and the outside of the coil is protected by an insulated sleeve 33. Specification 799,471 is referred to.
