Description
Technical field
The present invention relates to composite metal plate explosive welding field more particularly to a kind of TMCP type bridge steel stainless steel clad plates
Explosion welding manufacturing method.
Background technique
With the continuous improvement of bridge construction tempering ratio, the good physical of the existing plied timber of stainless compound steel plate is changed
Performance is learned, and has the high intensity and toughness of base material, traditional armored concrete is compared, the weight of bridge itself can be mitigated significantly
Amount, while extend the service life of bridge floor, it is used widely in bridge construction；In view of the high-strength height of TMCP type bridge steel
Tough, superior weldability, it has also become bridge stainless steel clad plate substrate designs main material；Existing TMCP type bridge steel stainless steel double
Plywood mainly uses rolling mill practice, has not only needed high-temperature water cooling solution treatment to guarantee cladding stainless steel intercrystalline corrosion performance, but also need TMCP
Technique guarantees Substrate sheet mechanical property, complex procedures, operating difficulties, and requires height to capacity of equipment, is suitable only for cut deal, raw
Finite thickness is produced, more specifications, small lot production are not suitable for.
Explosive welding is a kind of Solid-phase welding method, causes touching rapidly for weldment using the impact force that explosive charge generates
It hits, realizes connection weldment, weld seam is formed between two or more layers are of the same race or different metal materials, commonly used between dissimilar metal
Welding in the composite can be abundant in one the advantages of due to its unique two or more material of production technology sum aggregate
The performance for playing different metal material, greatly reduces the usage amount of rare precious metal material, saved the manufacture of equipment at
This, is widely used in the fields such as chemical industry, petroleum, water conservancy, printing and dyeing, electronics, has a vast market application prospect.
Compound plate is usually placed on above substrate, then explosive is placed on compound plate by explosive welding when specific operation
Then surface utilizes middle part ignition charge of the priming device from compound plate, keeps explosive gradually quick-fried along the length direction of compound plate and substrate
Fried, the shock wave that explosive charge generates can also be transmitted along the length direction of compound plate and substrate, and as the transmitting of shock wave makes again
Plate is gradually collided to the upper surface of substrate, to be bonded with substrate and be welded into one piece of composite plate, this structure is suitable for length
In Explosive Welding less than 10m, and the length of bridge steel is generally not less than 10m, belongs to overlength composite plate and discomfort
Explosive welding is carried out with the method.
Above-mentioned explosion welding method in the specific implementation, the energy of explosive charge can along the transmitting of impact wave direction two sides and
Constantly superposition be easy to cause the both ends of composite metal plate length direction to deform or be broken, due to multiple especially in overlength composite plate
The length of plate and substrate is longer, and energy supposition effect becomes apparent；Also, because compound plate is two started from the center to substrate
Side fitting, so the air between compound plate and substrate also can gradually be discharged with the formation of composite plate, but in overlength composite plate
Since the distance between compound plate and substrate are smaller in explosive welding, and not only length is longer and the speed of fitting for compound plate and substrate
Comparatively fast, partial air be discharged can not in time, cause the binding face ripple of compound plate and substrate coarse, generate strip or large area
Non- recombination region, cause the recombination rate of overlength composite plate lower, influence the quality of overlength Explosive Welding, it is therefore, existing
Explosion welding method have defect, it is difficult to directly apply in the explosive welding of TMCP type bridge steel stainless steel clad plate.
Summary of the invention
