Titanium Clad Steel Plate

Titanium because of its excellent corrosion resistance for a large number of containers, the heat exchanger material of a variety of chemical reactions, but the disadvantage is the high cost. This problem is particularly prominent in particular, when used as structural components, effective solution is to use titanium clad steel plate. The titanium composite material with ordinary steel called the titanium steel composite material, both the corrosion resistance of titanium, another ordinary steel as the strength of the structure, it is important that the costs are greatly decreased.

In recent years, titanium clad steel plate has been added to the new use in marine civil engineering field that became applicable to the steel structure of the anti-corrosion material. This is not only because of its lower cost, titanium clad steel plate welding installation of the steel structure as the main point of view, it must be used.

Overview of titanium clad steel plate
What is titanium clad steel plate?
Titanium clad steel plate in general steel surface with good corrosion resistance of titanium coated, corrosion resistance of ordinary steel naturally improve.
JIS standard, the board is mainly used for pressure vessels, boilers, nuclear reactors, reservoir, are composite thickness up to 8mm steel specification number G3603.

History of titanium clad steel plate
The Japanese titanium mill production began in 1954, titanium clad steel plate since 1962. Then the production method called explosion composite method, a method of bonding with explosives outbreak can. In 1986, developed a method of hot-rolled heavy plate rolling method. In 1990, developed the production method of continuous hot-rolled coils, mainly refers to the production of the sheet.

Applications of titanium clad steel plate
Explosion method, heavy plate rolling method of manufacturing titanium clad steel plate is a thick, its purpose is mainly used as the corrosion resistance of construction materials. Chemical equipment, the tube plate of the condenser of the high-purity terephthalic acid equipment, etc. used in power generation equipment.
Continuous hot-rolled manufacturing titanium clad steel plate, sheet, mainly used in the lining of the marine steel structures, applications for marine civil engineering.

Titanium clad steel plate manufacturing method
The general composite steel plate manufacturing method: filler metal the ingot rolling Law, explosive compound method, rolling crimping method, surfacing law. The titanium clad steel plate of the occasion, taking into account the characteristics of the titanium, is often used in the industrial the explosive clad method or rolled crimping method, while the actual production methods include rolling crimping method also includes ② ① explosive composite slab rolling Method ③ continuous hot rolling method. Explosive composite method is usually conducted at ambient temperature, rolling crimping method of the plate assembly, heating and rolling.

Explosive compound method
Explosive composite method points: For pressure contact between two metal plates to keep a certain spaced, on the amount of explosives in its upper recapture. By the end of the explosives to detonate explosive speed of several kilometers per second, by virtue of the outbreak can be titanium plate collision from the point of view of the base steel sheet. The exclusion out clean between surfaces shows that due to the very large deformation speed and ultrahigh pressure fluid behavior of the oxide film of the two metal surfaces, the gas adsorption layer in the base material steel plate and the titanium plate of the collision point as a metal spray bonding instantaneous called cold bonding.
The use of titanium clad steel plate manufactured by the Act may continue hot rolled to plate thickness 4mm, so they called explosive compound.

Heavy plate rolling method
Heavy plate rolling method initially titanium plate (composite material) with steel plate (substrate) embedded slab assembly. Then, in suitable intermediate between the titanium plate and the steel into the embedding material, and then under high vacuum, using electron beam welding. Finally into the furnace for heating, extreme pressure on the plate mill rolling to the desired thickness, so that the titanium plate and steel plate is really bonded. Finally, the peripheral cutting, is separated into two plates.

Continuous hot rolling method
The continuous hot rolling method and the slab rolling method is substantially the same, the difference is added by the middle of the two plate is a steel plate in the atmosphere of arc welding, and finally in a continuous hot rolling machine continuously rolled to the required thickness to the tape roll the form of removal. Finally, the peripheral cutting, is separated into two plates.

Applications:
Equipment in the field
In the field of equipment mainly refers to the previously described similar phthalate manufacturing equipment, chemical equipment, power plant condenser tube plate electrical equipment. Especially the power sector shipments have totaled more than 1000. In the field is the pillar industry of titanium clad steel plate. Recent topics: paper mill bleach treatment tank, the sewage treatment plant secondary chlorite the harsh sodium hydrochloride treatment tank also using titanium clad steel plate.

Marine civil engineering field
The maintenance problems of the marine structure
Japan is surrounded by sea, the base of the economic activity in the offshore area, with the needs of economic development, circulation, transportation, urban functions, facilities space are taking advantage of the sea, and from the inland sea, within the shallow waters of the Gulf off the coast of The deep waters of the development. To this end, Japan has set up a very large floating Technical Study Group, durable 100 years of very large floating marine structures on the scale of a few kilometers, theoretical research and field trials. Titanium has excellent corrosion rarely Dissolved ions in seawater environment, non-toxic and do not have to worry about the pollution of the environment, etc., and thus become the material of choice for marine structures.

Development of titanium clad steel plate
As described in Table 1, titanium has a very good corrosion resistance in flowing seawater, there are currently two ways to make the titanium material can be used as the marine structures anticorrosive material. A titanium sheet and organic compound made of corrosion-resistant material coated material; second method is coated with titanium clad steel plate welded to the new building. For the second method, there are still two kinds of problems, one of which is titanium engagement as lining. The only titanium alone is used as the structure is not established in the economic. Only by giving full play to the corrosion resistance of titanium, the structures main steel manufacturing is the economy. Titanium directly the formation of brittle intermetallic compounds with iron welding, however, is not practical. Titanium clad steel plate only titanium and steel hot rolled integration process, the steel part of the composite plate welding joint body of steel structures, and then take advantage of the corrosion resistance of titanium composites. Second titanium clad steel plate size problem. Because they can not produce the titanium steel composite sheet, plate thick with the material as a lining material to its size and shape is restricted. Therefore, manufacturing process of the thin steel sheet using a continuous hot rolling mill, the thickness of only 5mm coil-shaped titanium composite thin steel sheet. The bonding strength of the composite plate of approximately 150-200MPa, slightly higher than the predetermined value of the Japanese standard JIS-G3603 and the anticorrosive material suitable as the lining material.

This titanium clad steel sheet is advantageous in that: (1) titanium in seawater substantially no corrosion, nor dissolution of titanium metal ion; (2) titanium organism is not toxic, and no effect on the surrounding ecological environment; (3) If titanium corrosion does not occur in the ultra-long-term time, so is an extremely friendly on the environment in terms of the material.

Conclusion
The titanium steel composite board has experienced since its birth 40 years, its main application field of the condenser tube sheet has been used by more than 1000. On the other hand, in the Ocean Civil begin using, and will have more opportunities. Titanium clad steel plate is the effective use of the strength of the excellent corrosion resistance of titanium and steel, the cost to reach the best Combination future, looking forward to further development in this regard.
