Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] like figure 1 As shown, the vacuum system for the production of titanium sponge in a 7.5-ton I-type furnace of the present invention includes three low, medium and high vacuum pumping passages, and the components include a still 1, and the still 1 is connected to the first pneumatic baffle valve through a three-way connection. 2 and the second pneumatic flapper valve 3, the connection at this place is connected by a vacuum pipeline, the same below. A vacuum gauge 16 is also arranged between the distiller 1 and the tee.

[0021] The first pneumatic flapper valve 2 is connected to the first catcher 4, the first catcher 4 is connected to the first manual valve 5, the first manual valve 5 is connected to the second manual valve 6, and the second manual valve 6 is connected to The third pneumatic baffle valve 7 is connected to the first screw pump 8 . Wherein, a vacuum...

Abstract

The invention discloses a vacuum system for producing sponge titanium in a 7.5-ton I-type furnace, which belongs to the field of sponge titanium preparation and solves the problem that pump oil pollutes sponge titanium in the existing vacuum system using a slide valve pump as a roughing pump. The technical scheme adopted in the present invention is: a vacuum system for producing titanium sponge in a 7.5-ton I-type furnace, including three low, medium and high vacuum pumping passages, and the low vacuum pumping passage: distiller-first pneumatic baffle valve-first Tractor-first manual valve-second manual valve and third pneumatic baffle valve-first screw pump; medium vacuum pumping path: distiller-first pneumatic baffle valve-first trap-second One manual valve - pneumatic flapper valve - third manual valve and fourth pneumatic flapper valve - Roots pump - second screw pump; high vacuum pumping path: distiller - second pneumatic flapper valve - second capture Device-oil booster pump-third manual valve and fourth pneumatic baffle valve-Roots pump-second screw pump. The invention is suitable for preparing sponge titanium by vacuum distillation.

Description

technical field [0001] The invention belongs to the field of sponge titanium preparation, and in particular relates to a vacuum system for producing sponge titanium in a 7.5-ton I-type furnace. Background technique [0002] Titanium and titanium alloys have the characteristics of high strength, corrosion resistance and high temperature resistance, and are widely used in aerospace, deep sea exploration, chemical industry, medical treatment and other fields. Sponge titanium is used as a raw material for the preparation of titanium and titanium alloys, and is industrially prepared by magnesia thermal reduction. Magnesium reduces TiCl 4 The resulting titanium sponge has 8-12% MgCl remaining 2 , 25 to 30% of Mg is generally separated by vacuum distillation in industry. [0003] The vacuum system is an important part of the sponge titanium production device, and its ultimate vacuum degree, pumping rate, air tightness and other properties directly affect the vacuum separation ef...
