Titanium rod has good physical and chemical properties, low density, light weight, non-magnetic, high strength, good corrosion resistance, it has good mechanical properties and welding performance, Baoji titanium rod is widely used in chemical equipment, seawater In desalination, ship parts, electroplating industry, etc., the corrosion resistance of titanium is 10 times that of ordinary stainless steel, and titanium metal is a metal with low human rejection, so the processed parts of medical titanium rods are widely used in human implantation and medical equipment. use.
The reducing activity of various reducing agents to ilmenite decreases in the following order: charcoal>anthracite>petroleum coke>metallurgical coke. Charcoal has high activity and can make the charge have greater resistance, but it is expensive and should not be used. Petroleum coke has high carbon content and low ash content, but low activity and high price. It is not an ideal reducing agent and is only used in small-scale production of high-quality titanium slag. Production practice at home and abroad shows that anthracite is a suitable reducing agent for smelting high-titanium slag, its carbon content and activity are high, its price is low, and its source is reliable. ~340k0/cm3), but should choose anthracite with low ash, low volatile and low sulfur.

Titanium rod 12
In principle, all carbon-containing materials such as coal, petroleum coke, metallurgical coke, charcoal and graphite powder can be used as reducing agents for smelting high titanium slag.
Considering the rationality of process and economy, the reducing agent with high activity, low electrical conductivity, low ash content, low volatile content, low sulfur content and cheap should be selected. The high activity of the reducing agent can increase the reduction speed, reduce the smelting time, reduce the energy consumption and improve the production capacity. The conductivity of the reducing agent is low, which can improve the performance of the charge and ensure a reasonable power supply system. The ash content of the reducing agent is low, which can reduce its pollution to the product high-titanium slag. The volatile content of the reducing agent is low, which can reduce the exhaust gas in the smelting process and is beneficial to the stability of the furnace condition. As mentioned above, sulfur is a harmful impurity of smelting iron slag, and undoubtedly a low-sulfur reducing agent should be selected as much as possible.

Commonly used heat treatment methods are annealing, solution and aging treatment. Annealing is to eliminate internal stress, improve plasticity and organizational stability, and obtain better comprehensive properties. Usually, the annealing temperature of α alloy and (α+β) alloy is selected at 120-200℃ below the (α+β)-→β phase transformation point; solution and aging treatment is fast cooling from high temperature region to obtain martensite α′ phase and metastable Then, these metastable phases are decomposed by heat preservation in the medium temperature zone, and finely dispersed second phase particles such as α phase or compounds are obtained to achieve the purpose of strengthening the alloy. Usually (α+β) alloys are quenched at 40-100°C below the (α+β)─→β phase transition point, and metastable β alloys are quenched at 40~80°C above the (α+β)─→β phase transition point. The aging treatment temperature is generally 450 to 550 °C.

In summary, the heat treatment process of titanium alloys can be summarized as:

(1) Stress relief annealing: The purpose is to eliminate or reduce the residual stress generated during processing. Prevent chemical attack and reduce deformation in some corrosive environments.

(2) Complete annealing: The purpose is to obtain good toughness, improve processing properties, facilitate reprocessing and improve the stability of size and structure.

(3) Solution treatment and aging: The purpose is to improve its strength. Alpha titanium alloys and stable beta titanium alloys cannot undergo strengthening heat treatment, and only annealing is performed in production. α+β titanium alloys and metastable β titanium alloys containing a small amount of α phase can be further strengthened by solution treatment and aging.

In addition, in order to meet the special requirements of the workpiece, the industry also adopts metal heat treatment processes such as double annealing, isothermal annealing, beta heat treatment, and deformation heat treatment.

Titanium metal has excellent corrosion resistance and mechanical properties, and is widely used in many departments. Especially in chemical applications, titanium can replace stainless steel as a corrosion-resistant material, which is of great significance in extending the service life of equipment, reducing costs, preventing pollution and improving productivity. In recent years, the scope of titanium used in chemical industry in my country has been expanding, and the amount of titanium has increased year by year. Titanium has become one of the main anti-corrosion materials in chemical equipment. As a corrosion-resistant structural material used in chemical equipment, titanium has become an ideal material in chemical equipment.
Chlor-alkali industry
The chlor-alkali industry is an important basic raw material industry, and its production and development have a great impact on the national economy. This is because titanium has better corrosion resistance to chloride ions than commonly used stainless steel and other non-ferrous metals. At present, titanium is widely used in the chlor-alkali industry to manufacture metal anode electrolyzers, ionic membrane electrolyzers, wet chlorine coolers, refined brine preheaters, dechlorination towers, and chlorine gas cooling and scrubbing towers. In the past, the main parts of these equipments were mostly made of non-metallic materials (such as graphite, polyvinyl chloride, etc.). Due to the unsatisfactory mechanical properties, thermal stability performance and processing performance of non-metallic materials, the equipment was bulky, energy-consuming and short-lived. , and affect product quality and pollute the environment. Therefore, since the 1970s, my country has begun to replace graphite cells with metal anode cells and ion membrane cells, and replaced graphite coolers with titanium wet chlorine coolers, all of which have achieved good results.
For example: the application of titanium wet chlorine cooler. The production of caustic soda by salt electrolysis is to generate a large amount of high-temperature wet chlorine gas. In the production of chlorine gas produced by electrolysis of salt in my country, the output and quality of chlorine gas were affected by the unreasonable cooling process or the corrosion of cooling equipment, and it also seriously polluted the environment. Titanium coolers resistant to high temperature and wet chlorine corrosion were put into production, which changed the production outlook of chlorine production in the chlor-alkali industry. Titanium is extremely resistant to corrosion in the environment of high temperature and wet chlorine gas. The corrosion rate of titanium in chlorine water at room temperature is 0.000565mm/a; in chlorine water at 80 °C, the corrosion rate of titanium is 0.00431mm/a; In wet chlorine gas, the corrosion rate of titanium at room temperature is 0.00096mm/a. Titanium wet chlorine coolers are often used in many chlor-alkalis, and some have been used for nearly 20 years and are still in good condition.

As a new material, titanium alloy has only been developed and used in my country's pharmaceutical industry, medical equipment, human implants and other fields for nearly 20 years. However, it has achieved great success, and achieved significant social and economic benefits, shortening the gap between my country and the advanced countries in the world.

In recent years, a large number of titanium materials and titanium equipment have been used in the technological transformation of many domestic pharmaceutical companies and in VC, VB and other products, which has also established a special position of titanium in the pharmaceutical industry.

Medical instruments and surgical instruments are also one of the fields that have developed rapidly in recent years. Due to the special advantages of titanium materials used as surgical instruments, they are deeply welcomed by surgeons, ophthalmologists, and cardiothoracic surgeons, and are also one of the development directions of surgical instruments today. .

Another remarkable feature of titanium alloys is that they have good biocompatibility, so they are selected as ideal human implant materials. For more than ten years, many research departments, medical schools, hospitals, etc. in the world and in my country have also done a lot of basic work and clinical research, confirming titanium as an ideal human implant material from the depth and breadth. Thousands of cases of artificial femoral head, artificial wrist joint, knee joint, artificial dental implant, skull repair, cardiac pacemaker, etc. have been recorded. After years of research, follow-up and comparison, in the reports so far, titanium is the human body. Implant physical ideal material.

All rods and plates can be processed, cut and delivered according to customer needs, and various titanium alloy precision parts can be customized and processed according to customer needs.

The specific strength (strength to weight ratio) of titanium and its alloys is very high among metal structural materials, its strength is comparable to that of steel, but its weight is only 57% of that of steel. In addition, titanium and its alloys have strong heat resistance, and can still maintain good strength and stability in the atmosphere of 500 ° C, and the working temperature in a short time can even be higher. While aluminum loses its original mechanical properties at 150°C and stainless steel at 310°C. When aircraft, missiles, and rockets fly at high speed, the engine and surface temperatures are quite high, and aluminum alloys are no longer competent. At this time, titanium alloys are very suitable. It is precisely because titanium and its alloys have comprehensive and excellent properties of high strength, light weight and strong heat resistance, when it is used to replace other metals in aircraft manufacturing, it can not only prolong the service life of the aircraft, but also reduce its weight, thereby greatly reducing its weight. improve its flight performance. Therefore, titanium is one of the promising structural materials in the aerospace and space industries.

Titanium and its alloys are mainly used in the aviation industry to make aircraft engines and airframes. Generally speaking, for aircraft with Mach number less than 2, the engine uses part of titanium and its alloys, and the fuselage generally uses aluminum alloy. For aircraft with Mach number 2, the amount of titanium used in the engine is increased, and the fuselage also needs titanium in part. For aircraft with a Mach number greater than 3.5, the engine inlet temperature is already very high, so titanium alloys cannot be used but superalloys are required, but the amount of titanium used in the fuselage is significantly increased.



Titanium and its alloys also have good low-temperature resistance. Even at the ultra-low temperature of -250 °C, it still has high impact strength and can withstand high pressure and vibration. Therefore, titanium and its alloys are used in rockets, missiles and spacecraft. Not only for the manufacture of engine casings and structural components, but also for the manufacture of high-pressure containers, such as high-pressure gas cylinders, low-temperature liquid fuel tanks, etc.

The alloying of the surface of the titanium tube can also be called a kind of coating. Compared with the oxide coating of palladium coated on titanium, it has the advantages of strong bonding force, wear resistance and corrosion resistance. Compared with titanium-palladium alloy, palladium has high surface content, which saves precious metal palladium, reduces cost, and also has excellent performance.
Aluminizing the surface of the titanium tube can reduce the hydrogen absorption tendency of titanium. It is a good aluminizing condition to mix 88% alumina, 4% aluminum fluoride and 8% aluminum powder and coat it on the titanium workpiece, and the temperature is 810 °C. The thickness and structure of the aluminized layer depends on the holding time. Using the infiltration method to aluminize, a thin coating with a thickness of about 2 mm can be obtained by diffusion in a short time, and the bonding force is good and does not affect the mechanical properties of the substrate. The coating consists mainly of the titanium oxide phase, which forms a very effective barrier against hydrogen permeation.
Titanium tube

After the palladium is plated on the titanium tube, the palladium-plated layer can be diffused to the surface area of ​​the titanium tube by different heating methods to form a titanium-palladium alloyed layer on the surface, thereby improving the corrosion resistance. Thermal diffusion or laser surface remelting are in principle feasible. Using a laser to irradiate the titanium surface to make it melt and condense rapidly, the pre-vacuum-deposited 150-micron palladium-plated film can be rapidly melted to form an effective palladium alloy.
