Abstract
The utility model relates to a NO8825 nickel-based alloy clad steel plate which is characterized by being provided with a double-layer composite plate, wherein one layer of the double-layer composite plate is a NO8825 nickel-based alloy plate, and the other layer thereof is a general steel plate. The NO8825 nickel-based alloy clad steel plate can effectively composite the NO8825 nickel-based alloy plate with the general steel plate, thus guaranteeing the composite steel plate to have the required strength under the premise of having all advantages of NO8825 nickel-based alloy, and further saving the using amount of expensive metal. Simultaneously, the NO8825 nickel-based alloy clad steel plate has extremely high welding quality and guarantee long-term stable use without dropping.
Description
Affiliated technical field
The utility model relates to the metallic explosive composite plate.
Background technology
NO8825 (0Cr21Ni42Mo3Cu2Ti) alloy belongs to nickel Fe-Cr HTS abros, and adds little metal molybdenum and copper.In oxidizing acid and reductive acid, this alloy has good corrosion resistance, stress corrosion dehiscence resistant, anti-spot corrosion and crevice corrosion behavior; Sulfuric acid and phosphoric acid also there is good corrosion resistance.This alloy has good cold and hot working performance, is easy to cold forming and welding.Typical case's range of application: the heating tube that sulfuric acid washing factory uses, container, and chain etc.; Cooled with seawater heat exchanger, marine prods pipe-line system, sour gas environment pipeline; Heat exchanger in the phosphoric acid production, evaporimeter, washing, dip pipe etc.; Air heat exchanger in the petroleum refining.But, satisfy the needs of intensity again, so NO8825 and common metal composite need be used because the market price of NO8825 is higher.
Explosion welding technique is the high-voltage pulse load that produces by explosive detonation, promote the another kind of material (base material) of a kind of material (multiple material) high speed inclined impact, its loading stress is higher than the yield strength of metal material far away, the moment property of loading procedure (generally with millisecond meter), the locality of material stand under load, interweaving occurs in the small adjacent domain of application point and mode such as moves at high speed, realizes the metallurgical binding of two kinds of metals, and the land is rendered as wavy metallurgical binding.Explosive welding is again the new and high technology a kind of of great practical value of carrying out the intermetallic welding and producing metallic composite as the energy with explosive.Its maximum characteristics are metallic combination to be welded together simple, rapid and strongly in moment.The advantage of comparing explosion welding technique with solder technology such as rolling, built-up welding, casting is:
Material adaptability and solderability are applicable to most ductile metal or alloy widely; Especially for the welding of large-area metal, can be described as unique method of attachment; Be not only applicable to the combination of intermiscibility metal, and be applicable to the combination of non-intermiscibility metal, be applicable to the metal and the alloy of compound between easy generation brittle metal yet; Have good thermal conductivity, low interface resistance, the land does not have the heat affected area and constitutes good joint performance, and the thermal process of moment does not have the interface or a spot of dissolving is only arranged.
Summary of the invention
The purpose of this utility model provides a kind of NO8825 nickel-based alloy composite steel plates to remedy the deficiency of prior art.
The purpose of this utility model is achieved in that the NO8825 nickel-based alloy composite steel plates, it is characterized in that: be provided with double layer composite board, wherein one deck is a NO8825 nickel-base alloy plate, and one deck is a general steel plate in addition.
Beneficial effect
The product that the utility model provided, can be effectively that NO8825 nickel-base alloy plate and general steel plate is compound, thereby guaranteeing that clad steel plate has under the prerequisite of all advantages of NO8825 nickel-base alloy, had the intensity of needs, thereby saved the use amount of expensive metal.This product has very high welding quality simultaneously, guarantees that steady in a long-term the use can not come off.
The utility model is further described by embodiment below in conjunction with accompanying drawing:
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The NO8825 nickel-based alloy composite steel plates is characterized in that: be provided with double layer composite board, wherein one deck is a NO8825 nickel-base alloy plate 1, and one deck is a general steel plate 2 in addition.
The specific embodiment
Embodiment:
With general steel plate 2 horizontal positioned, the 1 parallel thereon placement of NO8825 nickel-base alloy plate is evenly placed explosive at NO8825 nickel-base alloy plate 1 outer surface, and the explosion velocity of explosive is 1.8 * 10
3-2.2 * 10
3M/s, brisance are that 6-10mm, density are 0.6g/cm
-3-0.85g/cm
-3, by cap sensitive, under high brake pressure, the surface of NO8825 nickel-base alloy plate 1 and general steel plate 2 just bonds together firmly.Can obtain finished product through repair welding, Technology for Heating Processing, smoothing technology, trimming technology, mechanical polishing process or acid cleaning process again.
