Due to carbide defects and poor machinability of cold work die steel Cr12MoV (SKD11/D2), conventional forging and heat treatment processes tend to cause die cracking and short service life. This paper introduces key forging parameters, analyzes the drawbacks of conventional spheroidizing annealing, quenching and tempering processes, and proposes a combined forging-heat treatment process as well as three improved quenching and tempering processes (low-temperature, medium-temperature and high-temperature) with their respective applicable working conditions. The study verifies that high-temperature austenitization can refine carbides and greatly improve toughness. Optimizing carbide uniformity is the key to enhancing the steel’s performance. The combined forging-heat treatment process can balance product quality, energy conservation and production efficiency, which is worthy of widespread promotion.
1.The mainstream materials for forged steel cold rolling rolls include Cr2, Cr3, Cr5, Cr6, semi-high-speed steel and high-speed steel grades. 2.Forged steel cold rolling rolls are mainly applied as work rolls and intermediate rolls for various continuous cold rolling mills and single-stand cold rolling mills for ferrous metals; work rolls for cold and hot skin pass mills; work rolls and backup rolls for small-sized cold rolling mills; and cold rolling work rolls and backup rolls for non-ferrous metal rolling mills. 3.Forged steel cold rolling rolls adopt a three-stage smelting process consisting of electric furnace melting, vacuum refining and electroslag remelting (ESR). Combined with forging, multiple heat treatments, cryogenic treatment and machining processes.
Stainless steel forging is an essential manufacturing process used to produce high-quality, durable, and strong stainless steel components. These components are widely used in a variety of industries, including aerospace, automotive, energy, and construction.
