Description:
Heavy forgings such as forged rings, shafts, rollers, flanges, and gears are widely used in various industries including metallurgy, mining, and power stations. The manufacturing equipment includes 185MN or 100MN hydraulic presses with a forging ratio of over 4.5. Technical conditions follow standards like ASTM, EN, DIN, ASME, or GB.
The product can be customized based on your drawings or specific requirements.
Smelting Process:
EF+LF + VD+VC The process includes ingot → heat → forging → heat treatment (normalizing + tempering) → inspection → rough machining → UT → second heat treatment → finishing machining → inspection.
Applications:
Heavy forgings such as forged rings, shafts, rollers, flanges, and gears are widely used in various industries including metallurgy, mining, and power stations.
