Overall composite flange and manufacturing method thereof

Abstract

The invention relates to an overall composite flange and a manufacturing method thereof, in particular to a manufacturing method of flange connection parts made of metal composite materials such as titanium, alloy of the titanium, steel and the like which can easily form intermetallic brittle compounds. According to the overall composite flange and the manufacturing method thereof, the technology of machining composite materials through explosive welding is utilized, and a titanium or titanium alloy metal flat plate is explosive-welded to a steel plate firstly; then a titanium or titanium alloy short tube and a steel short tube are fusion-welded to the titanium side and the steel side respectively; tapping is conducted on the composite plate welded with the short tubes to form a flange hole blank; finally, a titanium or titanium alloy tube is explosive-welded in a blank hole to form an overall composite flange blank, and the overall composite flange blank is machined to be an overall composite flange part needed by the design by adopting a mechanical machining method. According to the overall composite flange and the manufacturing method thereof, the mechanical properties are reliably, the non-composite effect of the end formed by explosive-welding in the hole is effectively eliminated, overall metallurgical combination welding between titanium and the titanium and between the titanium and steel is guaranteed, the area of welding combination interfaces is large, and the combining strength is high.

Description

technical field [0001] The invention belongs to the technical field of processing metal equipment parts, and in particular relates to an integral composite flange and a manufacturing method thereof. Background technique [0002] For some modern engineering processing equipment and devices, especially the reaction tanks with highly corrosive environments, working media and working conditions, the materials need to have the ability to resist various complex corrosive media. This places high demands on the selection of equipment materials. Often these metal materials that meet the ability to resist complex corrosive media are some expensive metal materials, or even rare non-ferrous metal materials. If the entire equipment is made of such anti-corrosion materials, not only the manufacturing cost of the equipment is unacceptably high, but also sometimes difficult to realize in terms of technology. At present, for equipment under the condition of strong corrosive working medium,...

Problems solved by technology

Since the brazing material itself is not corrosion-resistant, the bonding strength of the composite material after brazing is low, which leads to a short service life of the short pipe flange structural parts during use, which leads to the inability of the entire equipment to continue to be used, resulting in a lot of waste
