Explosive cladding method used for transition base plate of helicopter deck of drilling platform

Abstract

The invention discloses an explosive cladding method used for a transition base plate of a helicopter deck of a drilling platform. An explosive welding formation method of a composite plate includingan aluminum plate, a titanium plate and a steel plate comprises the following steps that first, the surface of the aluminum plate, the surface of the titanium plate and the surface of the steel plateare cleaned; second, the aluminum plate is used as a first layer in contact with a corrosive medium, the titanium plate is used as a second layer used for transition, and the steel plate is used as athird layer for bearing a load; third, a rock emulsion explosive 1# with the detonation velocity equal to or higher than 2000mm/s is continuously laid on the surface of the aluminum plate, a detonation groove with the width of 20mm is laid on the rock emulsion explosive 1#, and an ammonium oil explosive having the detonation velocity equal to or higher than 2600mm/s is continuously laid in the detonation groove; and fourth, an initiation point is arranged at the center of the aluminum plate, and a detonator is arranged on the initiation point. By adoption of the explosive cladding method, therequirements for the cladding joint rate, the shearing strength and the tensile strength of large-area aluminum plate, titanium plate and steel plate explosion for development of the well-drilling petroleum industry can be met.

Description

technical field [0001] The invention relates to the technical field of composite plates, in particular to an explosive composite method for a transition backing plate of a drilling platform helideck. Background technique [0002] Because aluminum has high plasticity, good corrosion resistance, and good weldability in the annealed state, aluminum can be rolled into thin plates and foils, drawn into pipes and filaments, and extruded into various civil profiles; in most machine tools During machining such as turning, milling, boring, and planing at the maximum speed that can be achieved, a dense and firm Al2O3 protective film is easy to form on the surface of aluminum and its alloys. This protective film is only strongly affected by halogen ions or alkali ions. down will be destroyed. Therefore, aluminum has good resistance to atmospheric (including industrial atmosphere and marine atmosphere) corrosion and water corrosion. It can resist the corrosion of most acids and organi...

Problems solved by technology

[0003] At present, most of the high-end aluminum products used in China and the composite plate materials widely used in the petroleum industry (such as the transition plate of the helicopter deck) and aerospace technology are mostly imported from abroad, which is not only expensive, but also has a long delivery cycle. It is conducive to the promotion and application of aluminum-titanium-steel composite plate equipment in my country, and it is not conducive to the development of national industries. Therefore, independent innovation must be developed to develop a high-performance aluminum-titanium-steel composite plate manufacturing process, which will reduce equipment manufacturing costs and shorten the production process. Equipment manufacturing cycle will play a very important role
