What is explosive recombination?
The metal composite materials produced by Phohom new materials are all explosive composite technology. Explosive recombination, that is, a layer of explosive is coated on the base metal and the clad metal. The instantaneous ultra-high pressure and ultra-high speed impact of the explosive detonation can form a metal collision jet, so as to promote the clad metal material to incline and collide with the base metal material and realize the metallurgical combination of the two metals.
Is explosive compounding technology high?
Although the explosive composite welding process is flexible in production, it looks like a container, but in fact it has a high technical content. To produce a qualified metal explosive composite material, accurate control is required, including the selection of base material properties, explosive properties, initial parameters and dynamic parameters and system coordination.
What are the characteristics of explosive compounding compared with other processes?
The chemical composition and physical properties of the original materials of the explosive composite plate produced by the explosive welding process will not change. The composite material can be processed into a desired state according to actual needs. Moreover, the performance of the explosive composite plate is very outstanding. It can withstand cold and hot processing without changing the thickness ratio of the composite material, and has high bonding strength, which can give full play to the use performance of different metals.
What steps should be taken in the production of metal explosive composites?
Due to different application scenarios, different grades, specifications and final forms of metal explosive composite materials, Phohom new materials adopts RDDF(research, scheme, development and finished products) scheme to provide customized production and service for customers.
The production process of metal explosive composite plate produced by Phohom new material is generally as follows: material preparation – explosive composite – testing – heat treatment – leveling – cutting – surface treatment – delivery inspection – Coding and packaging.
Quality testing includes ultrasonic testing, mechanical testing, and third-party testing required by customers.
What metals can be used as the base cladding of explosive welding?
Explosive welding can realize recombination between any metal materials. The patented technology of Phohom new material can realize two or more layers of material composite.
Common base metals include carbon steel, alloy steel, stainless steel, copper and aluminum.
The commonly used metals for cladding include: alloy steel, stainless steel, copper and its alloys, aluminum and its alloys, titanium and its alloys, nickel and its alloys, zirconium, tantalum, lead, gold, silver, platinum, niobium, tungsten, etc.
What industries can metal explosive composites be used in?
Metal explosive composites are widely used in petrochemical, shipbuilding, rail transit, low temperature engineering, ocean engineering, metallurgy, heat exchange equipment, aerospace and other fields.
Composite materials used in different projects mainly have the following forms: composite plate, tube plate, pipe, head, structural joint, conductive joint, low temperature joint, etc.
For example, in electrolytic aluminum, the explosive welding block of aluminum steel / aluminum titanium steel (aluminum steel composite plate) used for the connection of guide rod and steel claw is the explosive welding process; Copper aluminum composite plate / transition plate / copper aluminum joint can be used in graphitization furnace, new energy and other fields; Nickel steel composite plate / tubesheet and titanium steel composite plate / tube sheet can be used in pressure vessels and heat exchange equipment; Steel aluminum marine joints can be used for the connection of ships and rail transit; Aluminum titanium steel low temperature joint can be used for low
