The production of titanium sponge of magnesium reduction method

A magnesium chloride cycle, production of titanium sponge , magnesium reduction process is to chloride as chlorinating agent, reducing agent to magnesium. Magnesium and chloride containing titanium sponge plant 's products, the main by-product generation for anhydrous magnesium chloride.

  Anhydrous magnesium chloride is a good raw material for magnesium smelting, recycling is an important measure to reduce the cost of production of sponge titanium. Production of  titanium sponge ( aerospace castings )by Kroll Process Factory, are equipped with anhydrous magnesium chloride electrolysis workshop, recovery of metal magnesium and chlorine.

The core of the production of titanium sponge

Reduction, distillation process is the core of the production of titanium sponge , non union, semi joint and combined technology division.

  American Titanium Metal Company (TIMET) and Oregon Metallurgical Company (0RMET) have a style of one's own non united method used, reducing treatment of reactant leaching acid with TIMET,titanium ingot price 0RMET not only with a unique horizontal reduction pot reduction reaction, but also with helium as the carrier, from the tank residual magnesium and magnesium chloride.

The supply of titanium sponge

Japan and the former Soviet Union, China titanium sponge plant all adopt vacuum distillation treatment reaction. Semi joint and combined process is the main design scheme selection.

  Crushing sponge titanium sponge titanium is an important link of goods provided. Chinese Titanium Casting Manufacturer has used two crushing system,

(1) to the hydraulic press and the jaw crusher crushing system machine.
(2) the crushing system in oil press and roll crusher etc.. The latter is a more advanced, suitable for the production of grain character large quantities of goods titanium sponge in compliance with international standards.

Titanium sponge plant and chloride furnace

In the design of titanium sponge plant , the general use of open type or closed type three-phase arc furnace smelting of titanium slag. The former low thermal efficiency, high energy consumption, poor labor conditions and low yield.

  Chloride furnace has several types, vertical furnace, a sieve plate fluidized chlorination furnace, no sieve fluidized chlorination furnace and molten salt chlorinator etc.. aerospace castings

  Furnace type selection depends on the grade of raw materials, harmful impurities (Mg, CA), the content of raw materials, energy consumption and metal yield.

  Calcium and magnesium chloride containing fewer impurities titanium raw material, selects the fluidizing chlorination furnace. Molten salt chlorination device is an effective device for processing low grade and high content of calcium and magnesium rich titanium sponge material, but there must be effective facilities disposal or recycling of waste salt.

Four refining process of crude titanium tetrachloride of titanium sponge

Coarse titanium tetrachloride refining process by four vanadium removal and separation of four chlorinated silicon two system components. Four refining process for coarse titanium tetrachloride in the production of titanium sponge , and the two system. In addition to the four chlorinated silicon technology is not suitable for the production of titanium dioxide.

  Chinese separation of four chlorinated silicon using float valve tower device. Vanadium removal by using mineral oil, hydrogen sulfide, aluminum and copper and copper titanium sponge powder method.

  The production of precision industrial four titanium chloride, vanadium removal technique to replace the metal vanadium removal work much with non metal art.( Titanium Golf Club Heads )

Titanium sponge chloride process

The chlorination process of low productivity, poor labor conditions, but also must be equipped with briquetting and coking process facilities have been gradually eliminated.

  Twentieth Century at the end of the 50's to 70's,titanium sponge powder have developed into a molten salt chlorination and fluidizing chlorination (boiling chlorination) new technology.

  Application of two kinds of process, depends on the composition of raw material, molten salt chlorination of titanium slag is suitable for treatment of Gao Gai, magnesium content,general and multi-purpose the fluidization of chloride production coarse( titanium sponge ) four titanium chloride.

Early sponge titanium production

Chlorination process choice depends on the TiO2 content in raw material. Many western countries to natural rutile (95% ~ 98%TiO2) and high-grade artificial rutile as raw material, the process is simple, chloride, low material consumption, high utilization rate of chlorine and simple equipment system.

  China titanium slag as raw material, the content of impurity, high material consumption, low utilization rate of chlorine, equipment system is huge.  Titanium sponge production early, some factory used shaft EAF process.

Production of sponge titanium materials

Magnesium reduction process is composed of process of titanium concentrate or titanium rich material, refined, chloride reduction distillation and broken packing etc..

  China lack of natural rutile, titanium sponge production of raw materials can only be based on by the rich titanium material titanium iron enrichment.

  Rich titanium material is referred to as the titanium slag and rutile in commodities. The production of artificial rutile titanium slag and process had electric method, hydrochloric acid direct decomposition of titanium concentrate, combined dressing and smelting of dilute hydrochloric acid leaching method and reductive leaching pressure leaching method, pre oxidation fluidized acid etc..

Judging from the above process complexity, multi-purpose furnace smelting of titanium slag.

Reduction dose of per tonne of titanium sponge

The two kind of method choice, depending on the country of magnesium, sodium output and price.

  In the two method, reduction of dose per tonne of titanium sponge production required, sodium nearly twice higher than magnesium, sodium price must be less than half the magnesium, sodium reduction method have the competitiveness.

Comparison method for industrial production of titanium sponge

Sponge titanium production quantity by Kroll, accounts for more than a total of 80% world production of sponge titanium. Klau Apha is the advantage of the purification by distillation of the products of good quality, chlorine content is low, in favor of processing smelting.

  Chlorine content and gas Hunter method of product impurities, processing and smelting difficult, but less investment, finished product size of titanium sponge alloy for small.

  Easy preparation, powder metallurgy.
