Russia has long been utilizing cold extrusion technology for making thick steel plates from a variety of high strength materials. The process mainly involves pressing metal plates through a die at cold temperatures. This technology is widely used in the manufacturing of various components such as gears, bushings, shafts, sprockets, rollers, hubs, and other complex parts.
Cold extrusion is a fast and efficient way of shaping metal that enables it to achieve a desired shape or form with minimal heat input. This is especially useful in making complex metal shapes with tight tolerance specifications where other methods such as machining could not be achieved. Cold extrusion creates a metal shape with a superior mechanical and structural integrity compared to other metal forming methods.
The process differs from hot forging, as the metal is not heated before passing through the die. Instead, cold extrusion is used to shape metal in its cold state. The cold extrusion process forces metal through the die to achieve an exact shape or form.
Cold extrusion requires a high-strength steel that is strong enough to withstand the intense pressure created by the process. The steel must also be able to maintain its structural integrity and resist fatigue during high-stress applications. Common steels used for cold extrusion include structural steels, stainless steels, high-speed steels, and tool steels. The type of steel required will depend on the application and its specific requirements.
For the production of thick steel plates, the cold-extrusion process is combined with the roll-forming process. During the roll-forming process, the high-strength steel is rolled several times over a set of rollers to achieve a desired shape or form. This roll-forming process can be used to produce a variety of metal products including flat metal sheets, panels, and coils.
The cold-extrusion process results in steel plates of superior quality and strength. These steel plates are used in various applications such as in the manufacturing of bridges, pressure vessels, and other large structures. Cold-extrusion is also used in the production of automotive parts and components and in the making of bearings and other precision parts.
The Russian cold-extrusion process has revolutionized the metal fabrication industry. This process has allowed for the production of high-strength steel plates at an incredible rate of speed and with superior quality. Thanks to this process, many of the products used in today’s world are made from strong, durable steel plates that can withstand the pressures of high-stress applications.
