Problems solved by technology

In this process, zirconium tetrachloride will come into contact with air, which will produce deliquescence and consume part of zirconium tetrachloride, and deliquescence will produce waste of zirconium tetrachloride; in addition, there are also low efficiency of zirconium sponge reduction reaction and poor reduction reaction efficiency Defects
In production, zirconium tetrachloride and magnesium are placed in the zirconium tetrachloride reaction furnace and the reduction furnace respectively. The purified zirconium tetrachloride is gaseous, and the metal magnesium in the reduction furnace is liquid. The reduction furnace is connected, and the gaseous zirconium tetrachloride enters the reduction furnace equipped with liquid magnesium for reduction reaction to make zirconium sponge, but the efficiency is low and the quality of the sponge produced is low

Embodiment 1

[0003] In order to solve the above-mentioned technical problems, the present invention provides a kind of production equipment and technology of sponge zirconium, by setting the gas explosion tube structure of inert gas on the production equipment of sponge zirconium and gas explosion in the magnesium liquid of furnace gall and let explosive body Explosively increasing the reduction efficiency process achieves the purpose of improving the efficiency of zirconium sponge reduction reaction and improving the quality of zirconium sponge. In order to achieve the purpose of the above invention, the present invention provides a zirconium sponge production equipment, including a sublimation furnace and a first reduction furnace communicated with each other through a channel provided on the top, the channel is provided with a first one-way valve, the first A furnace body of a reduction furnace is provided with a furnace and a circulating water device, an insulating charge is provided be...

Embodiment 2

[0005] Embodiment 2 This embodiment is further improved on the basis of Embodiment 1, the difference is: Figure 6 As shown, in the zirconium sponge production equipment provided in this embodiment, a trachea branch is provided between the intake pipe 107 and the second one-way valve 108, and a third one-way valve 117 and an explosive body 118 are provided on the trachea branch. The storage box 116 has several explosive bodies 118 stored in the storage box 116. The air pump 109 first uses the negative pressure to suck the explosive body 118 into the branch circuit, and then uses the generated positive pressure to press the explosive body 118 into the intake pipe 107 And in the gas explosion tube 104 , the explosive body 118 is pushed out from the bottom of the gas explosion tube 104 by the pressure of argon gas and explodes in the magnesium liquid in the furnace 115 . In this embodiment, as shown in FIG. 7, the explosive body 118 is arranged in a spherical structure, the oute...

Embodiment 3

[0006] In this embodiment, the shell 119 is made of graphite, and the graphite is mainly composed of carbon, which can react with impurities in zirconium tetrachloride, such as reacting oxygen in it to produce carbon monoxide or carbon dioxide, which can be Oxygen in zirconium tetrachloride is removed, and the quality of zirconium sponge produced is higher; the preferred technical solution, because the shell 119 is made of a mixture of graphite and calcium carbonate, wherein calcium carbonate can form impurities with zirconium tetrachloride The reaction generates slag, and the slag will float on the surface of the first reduction furnace 10 liquid magnesium to absorb impurities and improve the quality of zirconium sponge; in addition, calcium carbonate can also react with chlorine in zirconium tetrachloride to generate chlorine Calcium and zirconium, increase the efficiency of the reduction reaction. In this embodiment, because the explosive body 118 is pressed out from the ga...

Abstract

The invention relates to the technical field of metal smelting, in particular to a production equipment and process of zirconium sponge. The production equipment of a kind of sponge zirconium provided by the present invention comprises the channel that connects the sublimation furnace and the first reduction furnace; The temperature and pressure device, the equipment for supplying inert gas, and the airtightly connected air inlet pipe. The air pump and the second one-way valve are arranged on the air inlet pipe, and the gas explosion pipe is arranged on the lower side of the air inlet pipe. Between the air inlet pipe and the second one-way valve There is a trachea branch, the trachea branch is equipped with a third one-way valve and a storage box for providing explosives, and the explosives are ejected from the bottom of the gas explosion tube by the pressure of inert gas and explode in the magnesium liquid in the furnace speed up the reduction reaction. The invention improves the production efficiency and quality of the zirconium sponge, and achieves good economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of metal smelting, and in particular relates to production equipment and technology of zirconium sponge. Background technique [0002] Sponge zirconium, also known as metal zirconium, is a silver-gray metal with a steel-like appearance and luster. It has very strong corrosion resistance and ultra-high hardness and strength. It is mainly used in aerospace, military, nuclear reactions, etc. At present, the production of sponge zirconium mainly includes two steps: the first step is to purify zirconium tetrachloride, remove impurities in crude zirconium tetrachloride, and purify zirconium tetrachloride; The production of zirconium is carried out by reduction reaction, that is, the zirconium tetrachloride after reduction and purification reacts with magnesium to produce zirconium sponge. In this process, zirconium tetrachloride will come into contact with air, which will produce deliquescence and consume part of...
