China vanadium and titanium resources are disorderly development

Chinese vanadium titanium resources due to become a byproduct of steel smelting was disorderly development, as many of China's iron ore fine vanadium and titanium ore often contains a large amount of vanadium and titanium resources, but there is a 'vicious circle' is its price is low ordinary mine, due to the extensive mode of production, many small mills with a very low price purchase such as iron ore, vanadium and titanium resources for no effective recycling, not only caused great waste of resources of vanadium and titanium, but also to the environment caused tremendous pressure.

In fact our large reserves of vanadium and medical titanium plate resources. According to statistics, currently the world's reserves of about 159.8 million tons of vanadium, which accounted for 46 percent of South Africa, Russia and the former CIS countries accounted for 23.6%, US 13.1%, China 11.6%, 6% less than the sum of the other countries. The basis of the world's titanium reserves of about 1.77 billion tons, accounting for more than 37 percent of China's. Reporters learned of vanadium and titanium resources are mainly distributed in Sichuan and Hebei Chengde Panxi, which Panxi vanadium-titanium magnetite resource most abundant resource of 618 million tons, accounting for about 95% of the country, accounting for 35% of the world.

"Although China is a big country of vanadium and titanium wire resources, but in recent years the issue of industrial development is also very prominent." An industry source said, in which the contradictions accumulate vanadium and titanium resource development and extensive development of the industry have become increasingly prominent, mainly in the non-standard resource development recycling resource level is not high, investment overheating tendencies, unreasonable product structure and so on.

"From a technical point of view, domestic vanadium and titanium recovery technology through decades of development, although vanadium, titanium mention, but still lagging behind Russia and other countries, technology can only be used in low-end products." Beijing Antaike analysis division said in interview, "Economic Information Daily" interview.

Another industry veteran who also admitted that at present a considerable part of the business continued to show a state of disorder on the vanadium and titanium rod stock resource development, no matter how large or small and medium enterprises, qualified or not qualified to see the resources on the development of business, some companies development process, do not pay attention to the production process and technical processes, product quality and resource utilization are not guaranteed, pollution of the environment is relatively large.

How to distinguish between titanium alloy doors and aluminum doors?

Titanium is added to the titanium-based alloy other alloying elements called titanium. Titanium has a low density, high strength, corrosion resistance, good process performance, etc., is an ideal material for aerospace engineering structures. Titanium and titanium plate alloys can be divided into structural heat titanium, titanium alloy or α, β-type titanium alloys and α + β type titanium alloy. Scope of the study also includes forming technology of titanium alloys, powder metallurgy technology, rapid solidification technology, titanium and other military and civilian.


Aluminum is made ​​of aluminum by adding some alloying elements, such as aluminum - manganese alloys, aluminum - copper alloy, aluminum - copper - magnesium-based hard alloy, aluminum - zinc - magnesium - copper based hard alloys. Aluminum is better than aluminum physical and mechanical properties: easy processing, high durability, wide application, good decorative effect, rich color. Aluminum into rust-proof aluminum, hard aluminum, super-hard aluminum and other types of various types have their own range, and have their own code, for users to choose.

Titanium alloy doors and aluminum doors should be in accordance with the following method to distinguish between:


1, the titanium-based alloy is added to other elements of the alloy known as titanium sheet metal. Titanium has a low density, high strength, corrosion resistance, good process performance, etc., is an ideal material for aerospace engineering structures.

2, aluminum is aluminum made by adding some alloying elements such as aluminum - manganese alloys, aluminum - copper alloy, aluminum - copper - magnesium-based hard alloy, aluminum - zinc - magnesium - copper based hard alloys. Aluminum is better than aluminum physical and mechanical properties: easy processing, high durability, wide application, good decorative effect, rich color. Aluminum into rust-proof aluminum, hard aluminum, super-hard aluminum and other types of various types have their own range, and have their own code, for users to choose.

3, aluminum remains the characteristics of the light, but the mechanical properties improved significantly. Use aluminum alloy material has the following three aspects: First, as a stressed member; the second is as doors, windows, pipes, caps, shells and other materials; the third is used as decoration and insulation. After the use of aluminum anodized features can be colored, made of various decorations. Aluminum plates, profiles can be surface corrosion, ginning, painting, printing and other secondary processing, made of various decorative plates, profiles, as a decorative material.

titanium grade 1 Why study the reaction of titanium plates with steam

Tests carried out in a vacuum apparatus with a quartz microbalance in the spring . Reading accuracy is 4 × 10 - sample surface g / cm . Mercury manometer measuring system connected to titanium grade 1 the reaction chamber using the pressure .
    Titanium iodide as a sample . Breaking titanium strip cold rolled to a rod 0.7 mm thick . Then cut the strip size is 9 × 25 mm sample . In order to eventually remove surface dirt , before the test sample with a finely sandpaper and etched in 7% HNO3 solution in HF .
    The tube is filled with distilled water and vacuum means connected to the plug and the device as a source of water vapor . In order to remove the dissolved water gasification will remain for some time in the water under the stars . Samples were heated to a predetermined temperature in a vacuum after the tube with water and the system is turned on, and set up the equilibrium vapor pressure corresponds to the temperature in the system . When the system is full , the system is filled with water and cut off the tube , and then tested in a closed volume .
    Under 800,850,900 and 950 ℃ titanium grade 7 rod and 14 mm Hg vapor pressure tested titanium plate and steam reaction .
    Kinetics of these tests indicate that , in the beginning stage of the reaction , the reaction with water vapor titanium plates subject to the parabolic law . After the reaction started after a certain period of time becomes linear parabolic law rule.
    In order to identify the effect of pressure on the reaction rate , once at 4 mm Hg pressure two experiments .
    Titanium plate during the reaction and steam , and any of metals, and also the reaction gas , is composed by a number of successive stages , in which the main are: 1 ) the gas molecules collide with the metal , 2 ) gas molecules adsorbed on the metal surface 3 ) the dissociation of the gas molecules , 4 ) through the surface of the film agent diffusion reaction product , 5 ) chemical reaction.
    The reaction rate depends on the speed of the pro stage . It was found that the reaction pressure is reduced because the rate of 5 /6 and steam manganese remains unchanged , so it should be acknowledged that the reaction speed depends on the diffusion of the reagents titanium grade 2 sheet through the surface of the membrane , since it is the only one speed stage and the gas pressure independent .
