Titanium steel composite plate


Titanium is widely used as various chemical reaction vessels and heat exchanger materials because of its excellent corrosion resistance, but the disadvantage is that the cost is high. Especially when used as a structural component of this problem is particularly prominent, an effective solution is to use titanium composite steel plate. Titanium and ordinary steel composite called titanium steel composite, both the corrosion resistance of titanium, there are ordinary steel plate as the strength of the structure, it is important that the cost is also significantly reduced.


In recent years, titanium steel composite plate has added a new use, namely in the field of marine civil engineering began to apply to the steel structure of the anti-corrosion material. This is not only because of its low cost, as the main body of the steel structure of the welding installation point of view, we must also use titanium steel composite plate.


Summary of Titanium Steel Composite Plate


What is the titanium steel composite plate?


Titanium clad steel plate refers to the ordinary ordinary steel plate surface with good corrosion resistance of metal titanium coating, ordinary steel plate corrosion resistance naturally increased.


In the JIS standard, the plate is mainly used for pressure vessels, boilers, nuclear reactors, storage, etc., are used in the thickness of 8mm or more composite steel, the specifications for the G3603.


The History of Titanium Steel Composite


The production of titanium in Japan began in 1954, titanium composite steel plate began in 1962. The method of production at that time was called the "explosive recombination method", and the method of joining with the explosive energy of the explosive. In 1986, hot rolling and thick plate rolling were developed. 1990 also developed a continuous hot-rolled coil production method, mainly refers to the production of thin plates.


Titanium steel composite plate applications


Explosion method, plate rolling method for the manufacture of titanium steel composite plate for the thick plate, its use is mainly used for corrosion resistance of structural materials. High-purity equipment such as phthalic acid chemical equipment, the condenser tube plate used in power generation equipment.


Continuous hot-rolled titanium steel composite plate for the manufacture of thin sheet, mainly used in marine steel structure of the lining, the application of marine civil engineering.


Titanium steel composite plate manufacturing method


General composite steel plate manufacturing methods are: filling the metal ingot rolling method, explosive composite method, rolling crimping method, surfacing and so on. In the case of titanium-steel clad plate, the explosive cladding method or the rolling-and-crimping method is often adopted in the industry in consideration of the characteristics of titanium. The actual production methods include ① explosive cladding method, Method ③ and continuous hot rolling method. The explosive compounding method is usually carried out at room temperature, and the rolling and crimping method is a process of assembling and heating the plate.


Explosive compound method


Explosive composite method points: first to be pressed to the two metal plates to maintain a certain interval between the place on top of the above and then put the right amount of explosives. Initiated by the end of the explosive, the explosion speed of several kilometers per second, with the outbreak of the titanium plate from the angle of the substrate plate collision. At the collision point, the substrate steel plate and the titanium plate exhibit fluid behavior at a very large deformation speed and an ultrahigh pressure. The oxide film and the gas adsorbing layer on the two metal surfaces are excluded as metal jets and clean surfaces Of the joint in an instant to complete, called the cold junction.


Titanium steel clad plate manufactured by this method can be hot-rolled to plate thickness of 4mm, so it is also called explosive compound method.


Thick plate rolling method


Plate Rolling Process Initially, a titanium plate (composite) and a steel plate (substrate) are assembled in an embedded slab. In this case, a suitable intermediate insert is placed between the titanium plate and the steel, and electron beam welding is performed under high vacuum. Finally placed in the heating furnace, the plate rolling mill to the required pressure to the thickness, so that the titanium plate and the plate is really joined. Finally, the peripheral cut, separated into two plates.


Continuous hot rolling method


The continuous hot rolling method is basically the same as the thick plate rolling method except that the steel plate is added in the middle of the two plates, the arc welding is conducted in the atmosphere, and finally the required thickness is continuously rolled on the continuous hot rolling mill, Form. Finally, the peripheral cut, separated into two plates.


Applications:


Equipment area


Application in the field of equipment mainly refers to the previously described similar to the phthalic acid production equipment, chemical equipment, power plant condenser tube plate with the power equipment. Especially in the field of electricity shipments have been accumulated to more than 1000. This field is the pillar industry of titanium steel clad plate. Recent topics: Bleaching treatment in paper mills and sub-chlorite hydrochloric acid treatment tanks in sewage treatment plants are also using titanium steel clad plates.


Marine civil engineering


Maintenance of Marine Structures


With the development of economy, the space of the facilities such as circulation, transportation and city functions is being used by the sea area, and from the shallow sea area of the inland sea and inner bay to the present sea area, Deep sea development. To this end, Japan set up a large floating technology research group, on the scale of a few kilometers, 100-year-old super-large floating structure of the sea for theoretical research and field trials. Titanium has excellent corrosion resistance, little dissolution of ions in the sea water environment, non-toxic, do not have to worry about environmental pollution, etc., and thus become the marine structure of the preferred material.


Development of titanium steel clad plate


As described in Table 1, titanium has very good corrosion resistance in flowing seawater, and there are two ways to make titanium material as a marine structure anti-corrosion material. One is made of titanium thin plate and organic corrosion composite cladding material; the second method is coated with titanium clad steel plate welded to the new building. As for the second method, there are two problems, one is the titanium as the lining of the bonding problem. The use of titanium alone as a structure is not economically viable. Only give full play to the corrosion resistance of titanium, the main body of the steel structure is the economy. However, brittle intermetallic compounds formed by direct welding of titanium with iron are also impractical. Only the titanium and steel using hot-rolled integration of the process of "titanium steel composite plate", the composite part of the steel plate welded joints will be the main steel structure, the use of composite titanium corrosion. The second titanium steel composite plate size. In the past, the titanium steel composite sheet could not be produced, and when the material was used as the lining material, its size and shape were limited due to the thickness of the plate. So the use of thin steel plate manufacturing process using continuous hot rolling mill, the thickness of only 5mm of coil-like titanium composite thin steel plate. The bonding strength of the composite steel sheet is about 150 to 200 MPa, which is slightly higher than the value stipulated in Japanese standard JIS-G3603, and is suitable for use as an anticorrosive material lining material.


(2) titanium organisms are not toxic to the surrounding ecological environment has no effect; (3) the titanium composite steel sheet has the following advantages: (1) titanium in the water is basically not corrosion, titanium metal ions will not be dissolved; If the titanium in the ultra-long period of time does not occur corrosion, then the environment will be a very friendly material.


Concluding remarks


Titanium composite steel plate since its inception has gone through more than 40 years, the main application areas of the condenser tubesheet has been used more than 1000. On the other hand, in marine civil engineering also began to use, and will have more opportunities. Titanium steel composite plate is the effective use of the excellent corrosion resistance of titanium and steel strength, the cost to achieve the best combination of the future look forward to further development in this area.
