Embodiment

[0013] A kind of reactor lid that produces sponge titanium is used, and it comprises cylinder body 7, panel 6 that is installed on cylinder body 7, bottom plate 3 below cylinder body 7, and cooling water ring 5 is installed on panel 6, in this reactor The cover is equipped with passage sleeve 1, feeder sleeve 2 and vacuum pipeline sleeve 4, which run through the panel 6 and bottom plate 3 of the reactor cover, and fill in the cavity surrounded by the panel 6, bottom plate 3 and cylinder 7 Insulation material 8—zirconium-containing Sierra cotton (also known as zirconium-containing ceramic wool), the bottom plate 3 of the reactor cover is an upwardly arched spherical shape, and a sleeve 9 is installed under the bottom plate 3 of the above-mentioned reactor cover to make the aisle The casing 1 and the feeder casing 2 are placed inside the sleeve 9 , and the vacuum pipeline casing 4 is outside the sleeve 9 .

Abstract

The invention provides a cover of a reactor used for producing sponge titanium. The cover comprises a barrel, a panel arranged on the upper part of the barrel, a bottom plate arranged on the lower part of the barrel; and a channel sleeve, a feeder sleeve and a vacuum piping sleeve are arranged on the cover of the reactor. The cover is characterized in that a cavity enclosed by the panel, the bottom plate and the barrel is filled with a heat insulating material-serra cotton containing zirconium, the bottom plate of the cover of the reactor is arched spherical, a sleeve barrel is arranged below the bottom plate of the reactor cover, the channel sleeve and the feeder sleeve are arranged inside the sleeve barrel, the vacuum piping sleeve is arranged outside the sleeve barrel. The reactor cover has the advantages of simple structure, easy manufacturing, light weight, safety and reliability and hard deformation, and can effectively avoid distilled materials from being directly pumped out by a vacuumizer and simultaneously does not affect the completion of the reduction reaction. The reactor cover has the functions of universal interchangeability, and can ensure the normal operation of production, and the product quality is not threatened, so that the main equipment problem of producing the sponge titanium by the combined method is radically solved.

Description

Technical field: [0001] The invention belongs to the technical field of smelting nonferrous metals, in particular to a reactor cover for producing sponge titanium. Background technique: [0002] In the production process of titanium sponge by magnesium method, the reaction tank and the large cover can be combined to form a complete set of reactors. The large cover plays an important sealing role in the working process of the reactor for producing sponge titanium by magnesium method. Due to the large single-furnace output of the inverted "U" type furnace and the large diameter of the reactor, the diameter of the reactor cover becomes correspondingly larger, which imposes very strict requirements on the structure of the reactor cover. Thermal deformation will lead to the opening of the welding joint, shortening the service life, and is a major threat to product quality. The original reactor cover adopts methods such as vacuuming or filling refractory materials to solidify to ...
