Abstract

Abstract The present invention relates to the art of producing refractory metals, and more particularly to apparatus for magnesium thermoreduction of titanium halides and subsequent vacuum separation of the reduction products. The apparatus proposed herein is characterized by that it is made sectionalized. A middle section thereof hermetically separates the spaces of a reaction chamber and a condenser, and functions as a heat screen. Through said middle section there pass a main channel adapted to communicate the spaces of the reaction chamber and consenser, a drive of a locking means adapted to shut off said main communication channel during the reduction process, communication channels for feeding reactants into the space of the reaction chamber, and a channel for connecting the condenser to an evacuation system, extending to the external surface of the middle section. The apparatus is intended, mainly, for producing titanium sponge.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 74 words
An apparatus as claimed in claim 1, wherein said middle section has a portion that extends into said condenser and forms an annular space with the internal surface thereof, the width of said annular space being so selected as to ensure the formation of a filtering bridge from the condensing products of the vacuum separation process between the edge of the extending portion of said middle section and the internal surface of the condenser.
Claim 2
Dependent Claim 17 words
An apparatus as claimed in claim 1, wherein the reaction chamber and the condenser are made interchangeable.
Claim 3
Dependent Claim 58 words
An apparatus as claimed in claim 1, wherein the middle section is made symmetrical to the transverse section plane and has a double number of communication channels outgoing from each side of said middle section and provided with plugs for shutting off said communication channels, depending on the operations being carried out in the reaction chamber and condenser.
