Abstract

The invention discloses a furnace cover for producing sponge titanium, which comprises a cylinder, a panel arranged on the cylinder, and a bottom plate under the cylinder, wherein, the furnace cover is provided with an aisle bushing, a feeder bushing and a vacuum pipeline bushing. The furnace cover is characterized in that: a sleeve is arranged below the bottom plate of the furnace cover to ensure that the aisle bushing and the feeder bushing are arranged inside the sleeve, the vacuum pipeline bushing is positioned outside the sleeve, the bottom plate of the furnace cover is of an upward vaulted spherical shape, and a heat insulating material, namely sayla cotton containing zirconium is filled in a cavity enclosed by the panel, the bottom plate and the cylinder. The furnace cover can effectively prevent distilled materials from being directly pumped by a vacuum unit, and does not affect the production of reduction reaction at the same time; the vaulted bottom plate has large anti-deformation ability, which solves the problems of furnace cover deformation, threatening weld craters, short service life and so on. The furnace cover has universal interchange function, avoids distillates from contacting the air to be polluted, and assures the steady operation of the production.

Description

Technical field: [0001] The invention belongs to the technical field of non-ferrous metal smelting, and particularly relates to a furnace cover for producing sponge titanium. Background technique: [0002] In the production process of magnesium sponge titanium, the reaction tank and the large cover can be combined together to form a complete reactor. The large cover plays an important sealing role in the working process of the magnesium sponge titanium production reactor. In CN200620109550.8, a large cover of a reaction tank for producing titanium sponge by magnesium method is disclosed, which consists of a cylinder, a panel and a bottom plate to form a large cover, and an evacuation sleeve, a feeding pipe sleeve and a large cover are installed on the large cover. The center tube is filled with slurry refractory material between the panel and the bottom plate, and after drying, the reaction tank lid is formed into a solid body. The vacuuming sleeve of the large cover and th...
