Dual-phase steel/titanium composite board explosive welding forming method

Abstract

The invention discloses a dual-phase steel / titanium composite board explosive welding forming method. The forming method comprises the following steps of: before explosion cladding, heating a dual-phase steel plate to certain temperature, adopting asbestos to preserve heat for the dual-phase steel plate, transporting the dual-phase steel plate to a working site, putting the steel plate at an interval, placing a titanium plate, adding a protective layer at the same time, fixing a heating belt at a proper position of the plate to ensure that the strength of the dual-phase steel plate in the high-temperature state decreases, finally, paving explosive according to the technological requirements, taking away the heating belt before explosion, ensuring the plate temperature, and flattening after detonation. With adoption of the method, the fitting quality of a dual-phase steel / titanium composite board is greatly improved, and the produced dual-phase steel / titanium composite board can meet the developmental demand of the petroleum technology.

Description

Technical field [0001] The invention relates to the field of composite plate manufacturing, in particular to an explosion welding forming method of dual-phase steel / titanium composite plates. Background technique [0002] Titanium / duplex steel composite plate tube sheets have been used in heat exchanger tube sheets of oil drilling platform equipment. There are some contradictions in the material combination of duplex stainless steel and titanium, especially in their heat treatment system. Composite The heat treatment system of the plate has also been controversial. The temperature that meets the titanium temperature will cause the duplex steel to have a brittle hard structure and even cracks. The temperature that meets the dual-phase steel will cause the structure of the titanium plate to oxidize and the corrosion resistance will decrease. In addition, the dual-phase steel will have a brittle hard structure and even cracks. The high strength of phase steel has always been a ...

[0002] Titanium / duplex steel composite plate tube sheet has been used in the heat exchanger tube sheet of oil drilling platform equipment. There are some contradictions in the material combination of duplex stainless steel and titanium, especially in their heat treatment system. Composite The heat treatment system of the plate has also been controversial. If the temperature of titanium is satisfied, the dual-phase steel will have brittle and hard structures or even cracks. The high strength of phase steel has always been a problem in explosive composite panels. Explosive composite materials are generally materials with similar properties and are easier to weld by explosion. High-strength materials and low-strength materials are difficult to metallurgically bond. Even if the welding is completed, the bonding strength is very high. Low, once unable to meet the needs of the market and actual use
