TIP of titanium and titanium alloys

TIP of titanium and titanium alloys
Titanium is a refractory metal of a light metal, a density of 4.5 g / cm3, 57% only of iron. Strength titanium plate alloy with high strength comparable to steel, but also has good heat resistance and low temperature performance, long-term work at certain alloy between 450 ℃ ~ 550 ℃ and minus 250 ℃.
Circular blade cutter suitable for milling titanium, because they may be appropriate to change the main angle. As long as these cutters equipped with special blades and apply the correct cutting parameters, under normal circumstances can improve the stability and overall performance. Feed per tooth should be set to the minimum amount, which is crucial.
Titanium and titanium - titanium milling need the right conditions compared with most other metal materials processing, titanium bolts processing requires not only higher, but more limited. This is because the alloy has metallurgical characteristics and material properties and cutting action may have a serious impact on the material itself. However, if you select the appropriate tools and use them correctly and in accordance with the requirements of the titanium processing tools and configuration optimization to the best condition, then fully meet these requirements, and obtain satisfactory performance and perfect results. Many of the problems of traditional titanium metal processing encountered is not inevitable, as long as the properties of titanium to overcome the effects of the process, we can succeed.
Various properties of titanium parts and materials to become a powerful attraction, but many of the properties but also affect its workability. titanium bar stockhas excellent strength - weight ratio, which is usually only 60% of the density of steel. Titanium elastic coefficient lower than steel, so the texture is harder, better deflection. Erosion-resistant stainless steel is better than titanium, and low thermal conductivity. These properties mean that titanium metal in the process will produce higher and higher concentration of cutting force. It is prone to vibrations caused by the tremor occurred while cutting; and, it is easy to react with cutting tool materials in cutting Shihai, thus exacerbating the crater wear. In addition, its thermal conductivity is poor, mainly because of the heat in the cutting area, so the processing of titanium metal tool must have a high thermal hardness.

Introduction What are the characteristics of titanium?

Introduction What are the characteristics of titanium?
Titanium used in petroleum, chemical, pharmaceutical, food industry, has a pivotal role. titanium bars and titanium alloys can be long-term work between 450 ℃ ~ 550 ℃ and minus 250 ℃. Titanium has good salt tolerance classes, the ability to seawater and nitric acid corrosion, Ti-30M alloy is resistant to high concentrations of hydrochloric acid and sulfuric acid corrosion.
Titanium for pitting, etching, stress corrosion resistance is particularly strong; alkali, chloride, chlorine, organic materials, nitric acid, sulfuric acid, etc. have excellent corrosion resistance. However, the corrosion resistance of titanium with a reduction of oxygen and chromium salts medium is poor. Here Xiaobian to introduce titanium characteristics.
Titanium plate is kind of the equivalent of the surface oxide film with a good durable wear hair separating agent, using titanium plate plates save seed separating agent, make peeling easier plate, eliminating the pre-treatment process kinds of plates, titanium plates than seed copper starting sheet to light half titanium starting sheet is more than three times the life of the copper seed plate, depending on the operating conditions of up to 10 to 20 years. Titanium plate preparation seed crystal structure of copper dense, smooth surface, good quality. Because titanium species sheet without smearing separating agent, and thus avoid the contamination of copper electrolyte.Increase productivity reduce copper production costs, which have better economic benefits.

Zunyi Titanium status quo can produce inevitable readjustment

Let Zunyi Titanium anxiety, as well as challenges from the market: Once the relocation of existing capacity, Zunyi Titanium inevitable readjustment, which allowed future business full of variables. 

Nearly seven years after efforts have not opened to door listing, Zunyi Titanium heat exchanger began to deal with another more complex projects: relocation. 
Zunyi Titanium according to previous listing and financing plan, the funds raised will be used to invest additional 10,000 tons of titanium sponge expansion project, the total investment totaling 999.8 million yuan. 
Zunyi Titanium chairman Guo Xiaoguang told the media that the reason to withdraw the IPO application, the main reason is that the overall relocation decision Zunyi Titanium, this move will affect the company's equity investment projects implementation. 
Zunyi City, according to local urban planning, and to the implementation of the southern industrial area "retreat into three city back into the park," the enterprise within the area covered by a "remote technical innovation, the overall relocation." Zunyi Zunyi Titanium Sheet Metal and titanium parent plants are in his column. 
But this move imperative call five or six years later, there has been no substantive movement. 
Zunyi Titanium a retired employee said, now move it, the government had no money, loss of business because no money, "you move to the area involved, the equipment, the original old equipment a move to be scrapped." 
It is reported that other companies can move equipment, machine tools away on the line, Titanium metal supply sponge enterprises to move, it can only be reconstructed, which makes this old state-owned enterprises dilemma. Reporters learned that, corporate relocation, the government does not give money, Zunyi Titanium now rely on loans already in production, the debt ratio of 50% or so. 
Because Zunyi Titanium Financial Officer on a business trip, the reporter was not informed of a more detailed financial data. 
Let Zunyi Titanium anxiety, as well as challenges from the market: Once the relocation of existing capacity, Zunyi Titanium inevitable readjustment, which allowed future business full of variables. "If we have money, we move past the first plant built and up and running, stopped on the line here. But now no money, then go over there and removed the side of production, to the market late in 2034, which how the line? "Panting Xiang said. 
It is understood that the domestic titanium plant by the first two grown to more than 40, affected by the financial crisis drained group, currently more than 20 left. In the meantime, titanium sponge along with the rapid expansion of production capacity, resulting in "more than 100,000 tons of production capacity, the use of only a few million" surplus situation. 
Panting Xiang believes that now the price has reached the bottom of titanium sponge, the future even if the rebound is small, "After all, the current production has more than tripled the demand." 
But relocation has become a trend, therefore, Zunyi Titanium can only hope to send bond financing, "now has a 5 million bond financing is in place in batches, January 19 this year, has come to a one hundred million." Panting Xiang said, without misappropriating public yet, but the bond issuers to repay.

Chemical classification of titanium

Chemical properties

Chemically, titanium exhibit good stability in a variety of industrial solutions have good corrosion resistance. Titanium is an excellent industrial refrigeration equipment parts and materials.
Commercially pure titanium compounds can be widely used in the alkaline solution, and a medium such as saline solution, and the reaction occurs with difficult, excellent corrosion resistance; inorganic titanium at room temperature a low concentration of hydrochloric acid, sulfuric acid, nitric acid and the like having good corrosion resistance; but with the increase in the concentration and temperature of the medium, commercially pure titanium and the above-mentioned inorganic acid is easy to react, so that a reduction in corrosion resistance of titanium, therefore, the heat exchanger should be noted that the concentration of the process medium and temperature; commercially pure titanium at room temperature for formic acid, oxalic acid, lactic acid and other organic acids having a good corrosion resistance.

Titanium compound with superior wear resistance

Titanium pigment to a number of areas from aerospace alloys have been widely known magical elements, perhaps in turn has a new purpose. American Afton Chemical Corporation and the National Institute of Standards and Technology (NIST) materials scientist, 23, said they found that the addition of the titanium compound into the oil (lubricant), the wear on the vehicle's engine can be formed easily damaged parts of the surface nano-coating to improve the wear resistance of oil. If the titanium compound in the future be able to replace oil in the current anti-wear additives, will be able to get environmentally friendly oil.
Engine oil is a complex mixture of mucus, wherein up to 20% of the ingredients for a particular additive, the purpose is to enhance the characteristics of the oil, such as viscosity and stability, to reduce engine wear and the formation of grease. Over the years, the oil antiwear performance mainly depends on the phosphorus compound, especially ZDDP. The compound forms a thin film on the polyphosphate engine parts, thereby reducing the wear rate components. But phosphorus is a chemical substance harmful to the vehicle catalytic converters, will reduce the efficiency of the catalytic converter and shorten its life. Therefore, the industry has long been looking for ways to replace or less of the substance or use of ZDDP. But never did find a solution.

Introduction and application of titanium copper composite materials

Metal composite material is a material made ​​of two or more chemically different combination of the starting monomer material, or is reinforced by the base material and the raw material and the obtained composite disposed new material. Compared with the monomer material, the composite material has a function of many things in common, the mechanical advantage is its primary function, the function of the physical or chemical function satisfactorily specific requirements or to reduce the cost function, which is the starting monomer material can not be achieved.
     Currently there are many types of titanium composite materials, such as titanium clad steel plate, titanium package copper rod, copper and titanium steel, titanium and other transition joints, titanium composite materials can not only satisfied the needs of users to use, and the price is lower than that of pure titanium or titanium alloy, welcomed by the mall. Such as titanium steel composite panels, both with the strength of steel, but also has the function of corrosion-resistant titanium, widely used in the metallurgical and chemical equipment production.

Titanium copper composite rod copper rod known as titanium package. Electrolytic copper metal anode is made of titanium composite rod support, its role has three points: First, to support the anode; two conductive; Third corrosion. For the satisfaction of these needs, the use of the corrosion resistance of titanium and copper conductivity, the contact with both. Composite bar intermediate copper, outsourcing a layer of titanium, a square lantern-shaped cross-section two, completely satisfied with the use of demand. Titanium copper composite billet in the extrusion process by strong pressure, metallurgy contact form two metal interface, waveform interface is the best way to contact the two metals, copper and titanium composite rod enhance contact reliability, resistivity small, conductive function better. Foreign developed a titanium-copper composite pipe, the copper outer titanium, its strength lies in saving copper materials, corrosion function better.
