Closed table bag for titanium sponge production

Abstract

The invention discloses a closed ladle for titanium sponge production. The closed ladle comprises an argon filling pipe 2 arranged at the upper part of a cavity of the ladle; a flow guide pipe A is arranged on the ladle cavity, a connecting flange A is arranged at the top of the flow guide pipe A, the connecting flange A is connected with a connecting flange B through a bolt, the connecting flange B is connected with an upper flow guide pipe B, and the upper flow guide pipe B is connected with a lower flow guide pipe C; a sealing gasket is arranged between the connecting flange A and the connecting flange B; the pipe diameter of the flow guide pipe C is larger than that of the upper flow guide pipe B; and if a magnesium emission accident occurs, the argon filling pipe is opened to damage the siphon. According to the invention, when magnesium is emitted during magnesium addition, the siphon principle during magnesium addition is destroyed, magnesium overflows out of the reactor, and expansion safety accidents and increase of production cost are avoided.

Description

Technical Field

[0001] The invention relates to a production device for titanium sponge, and in particular to a closed ladle for titanium sponge production. Background Art

[0002] Sponge titanium production adopts the Klauer process, which uses molten metal magnesium in a closed container composed of a reactor and a large cover to reduce titanium tetrachloride to obtain titanium and magnesium chloride. Before the reduction production, the high-temperature molten metal liquid magnesium must first be transported to the reduction production workshop through the magnesium adding bag, and the high-temperature liquid magnesium prepared in the electrolytic magnesium chloride process is transported to the reduction production workshop. The magnesium in the magnesium adding bag is injected into the reactor through the guide pipe using the siphon principle, and then the reduction production is carried out. When adding magnesium, if the magnesium bubbling phenomenon occurs, the existing technology does not destroy the siphon principle, and the magnesium in the magnesium bag can only be allowed to overflow from the reactor, resulting in the expansion of safety accidents and increased production costs. Summary of the invention

[0003] The invention aims to solve the technical problem that when magnesium is added to a magnesium adding bag, after magnesium bubbling occurs, it is impossible to prevent the magnesium in the magnesium adding bag from continuing to flow out.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A closed ladle for titanium sponge production, comprising an argon filling tube provided at the upper part of the ladle cavity; a flow guide pipe A provided on the ladle cavity, a connecting flange A provided on the top of the flow guide pipe A, the connecting flange A connected to the connecting flange B by bolts, the connecting flange B connected to the upper flow guide pipe B, and the upper flow guide pipe B connected to the lower flow guide pipe C; A sealing gasket is provided between the connecting flange A and the connecting flange B; The diameter of the lower guide pipe C is larger than that of the upper guide pipe B.

[0005] The beneficial effects of adopting the above technical solution are: 1. The present invention realizes the siphon principle of adding magnesium to the ladle during the titanium sponge production process, destroying the siphon principle of adding magnesium to the guide tube, and solves the technical problem that it is impossible to prevent the magnesium in the magnesium ladle from continuing to flow out.

[0006] 2. The present invention reduces production costs and avoids the expansion of safety accidents.

[0007] 4. The present invention has a simple structure and is durable. BRIEF DESCRIPTION OF THE DRAWINGS
