Combined technology of strengthening processing of special purpose products PP072
PURPOSE AND SCOPE
The technology is intended for manufacturing of various large steel products. The products must have a high strength, in particular the barrels of tank guns and various artillery and rifle systems. They under conditions of high gas pressure, wear and corrosion actions. The number of shots is more than 500. THE IDEA OF THE DEVELOPMENT
Integrated development allows to get a proper level of metal strength. It can be achieved during the finish thermal processing of trunk with maximum wall thickness of ≥100 mm. The product can be found in NATO countries with limit of proportionality ≥ 1400. Structurally - technological parameters of equipment, modes of combined processing were developed for applying protective covering to the surface channel of large - sized products and their further heat treatment. Due to the experimental - industrial testing it made it possible to get on chromium covering on the surface channel and significantly increase the life products. MARKET DEMAND The development has passed the experimental and industrial testing on the basis of the DKB "Pivdenne" with chrome plating. It can be used at the enterprises of metallurgical and machine - building industries of Ukraine in carrying out of state order on guns of artillery systems.
INTELLECTUAL PROPERTY STATUS
The development is protected by 6 patents.
