Description

Introduction to Forged Hollows Forged hollows are widely used in high temperature/pressure and other harsh conditions, such as hydrogenation reactors, nuclear reactor pressure vessels, evaporators, submarine oil and gas pipelines, etc., thanks to their durability, anti-corrosion features, high strength and long service life. IRAETA uses high-precision CNC rolling mills to manufacture forged hollows using the ring forging process, which, aside from shortening the lead time, also assures compact internal structure, fine grains and complete circumferential flow of workpieces, thus further improving the strength, wear resistance and fatigue resistance. Also, all kinds of workpieces with variable diameter can be manufactured using molds of different shapes. An efficient manufacturing method for reactor cylinder sections The SMS Meer super-rolling mill imported by IRAETA, can manufacture rings with a maximum diameter of 16 m and height of 3 m using the rolling process (ring rolling). The globally-advanced and renowned near-net shape forming manufacturing process, is applicable for forming rings and forged hollows. Forged hollows manufactured in this way are superior to the ones produced by traditional processes such as free forging, casting, plate rolling, in the following aspects: Faster delivery The process can ensure one-time forming with high quality surfaces and uniform cylinder thickness. At the same time, it can use direct quenched-tempered heat treatment, and does not require rough machining processes, all of which helps reduce machining time and improves efficiency.
