Quenching Deformation

Long forged shafts, gears and precision components may experience deformation during uneven cooling, especially in high-volume quenching lines.

Oxidation & Decarburization

Forged dies, bearing components and alloy steel parts often require clean surfaces and controlled atmospheres to reduce oxidation during heat treatment.

Hardness Inconsistency

Large forgings and continuous production environments require stable temperature distribution to maintain metallurgical consistency.

Continuous Quenching Solutions for Automotive Gear Forgings

For automotive gear forgings and axle shaft production, unstable hardness and inconsistent cycle times can reduce machining efficiency and create downstream assembly issues. Continuous quenching and tempering systems are commonly used to stabilize production rhythm while improving hardness consistency across high-volume forged components.

In continuous automotive forging heat treatment lines, temperature control, atmosphere management and cooling stability are critical factors affecting gear performance and fatigue resistance.

• Heat treatment for gears and synchronizer hubs
• Continuous production for forged auto parts
• Reduced oxidation during quenching
• Stable hardness distribution for alloy steel components

Annealing Process for Large Forged Shafts & Wind Power Components

Large forged shafts and wind turbine forgings often require long-cycle annealing and stress relief processes after forging. Uneven heating or unstable furnace temperatures may lead to residual stress, machining distortion and inconsistent mechanical properties.

For heavy alloy steel forgings such as 42CrMo and 34CrNiMo6, deep pit annealing systems are commonly used to improve microstructure stability before rough machining and final heat treatment.

• Annealing furnace for large forgings
• Stress relief for forged shafts
• Heat treatment for wind turbine shafts
• Temperature uniformity for oversized workpieces

Reduce Oxidation During Vacuum Heat Treatment of Forged Dies

For H13 dies, bearing components and precision forged parts, oxidation and surface decarburization can significantly increase machining cost and reduce final product quality.

Vacuum hardening processes are widely used where low deformation, clean surfaces and controlled metallurgical structures are required during heat treatment of forged tool steel and alloy steel components.

• Vacuum hardening for H13 steel
• Heat treatment for forged dies
• Low oxidation heat treatment process
• Dimensional stability for precision components

42CrMo Forgings

Commonly used in heavy shafts, wind power components and engineering machinery forgings requiring annealing and quenching & tempering.

20CrMnTi Gears

Widely used in automotive gear forging applications where continuous carburizing and quenching processes are required.

H13 Tool Steel

Typically used for forged dies and tooling where vacuum heat treatment helps reduce oxidation and improve surface quality.
