preparation example Construction

[0053] In another aspect of the present invention, a method for preparing titanium sponge using the aforementioned preparation system is proposed, figure 2 For the preparation method flowchart of the present invention, refer to figure 2 As shown, it specifically includes the following steps. Among them, in order to better describe and understand the process flow of the preparation system of the present invention, the present invention describes the combustion system on one side as the combustion system on the A side, and describes the combustion system on the other side as the combustion system on the B side. as follows.

[0054] (1) Add titanium tetrachloride and metal magnesium raw materials in proportion (mass ratio is 3-5:1) into titanium tetrachloride heating tank and metal magnesium heating tank respectively, after connecting the preparation system, use argon gas Replace the entire preparation system so that the entire preparation system is in an argon atmosphere, an...

Embodiment

[0064] (1) Add titanium tetrachloride and metal magnesium raw materials into titanium tetrachloride heating tank and metal magnesium heating tank respectively according to the mass ratio of 3:1, and after connecting the preparation system, use argon to replace the whole preparation system, Make the entire preparation system in an argon atmosphere, and turn on the vacuum system to maintain the system pressure <10Pa.

[0065](2) Put into the combustion system, use natural gas as fuel, adopt the single regenerative combustion method, and open the A-side combustion system: pass normal-temperature natural gas and normal-temperature air into the combustion chamber and burn through the burner, and the high-temperature flue gas generated by combustion passes through radiation, After heat transfer methods such as convection increase the temperature in the reaction chamber, heat is stored in the regenerator of the B-side combustion system, and then discharged through the flue gas pipelin...

Abstract

The invention provides a preparation system and method of titanium sponge. The preparation system mainly comprises a reaction system, a combustion system, an induced draught fan, a vacuum distillationsystem, and a vacuum system. The reaction system comprises a reaction chamber, a titanium tetrachloride heating tank, a magnesium heating tank, a cyclone separator, and a cooling tank. A fluidizationreaction mode is adopted, titanium tetrachloride and magnesium are fed into the reaction chamber in a steam mode; reactants carry out reactions after reactants contact with each other in the reactionchamber through a gas-gas or gas-droplet mode; the reaction efficiency is improved efficiently; the high temperature cyclone separator is used to separate raw materials, the raw materials are returned through a descending pipe, the utilization rate of raw materials is improved effectively, and the yield of titanium sponge is increased.

Description

technical field [0001] The invention belongs to the technical field of vacuum metallurgy, and in particular relates to a preparation system and method of titanium sponge. Background technique [0002] my country is rich in titanium resources, the reserves rank first in the world. At present, my country's titanium resources are mainly used to produce titanium dioxide, and the utilization rate is only about 30%. Titanium and titanium alloys have the advantages of low density, high specific strength, excellent corrosion resistance and non-toxicity, and are widely used in aerospace, chemical industry, metallurgy, light industry, shipbuilding, automobile, medicine, construction and other industries. As the potential demand for titanium and titanium alloys increases, the efficient use of titanium resources is becoming more and more important. [0003] At present, the industrial method of titanium metal production is the Kroll method. During the production process, titanium-conta...
