Fully Automatic Chain Induction Hardening And Tempering Machine With 15-56 Mm Link Chain Dimension

Duolin presents a high-precision, fully automatic system engineered for the industrial chain manufacturing sector. This comprehensive solution ensures superior stability and efficiency throughout the hardening and tempering processes.

Duolin is a professional manufacturer of induction heating machines since 1996. Our research and design team can overcome challenges to offer customers high-performance turnkey induction heating solutions. Our induction heating equipment is widely used for hot forging, induction hardening, induction heat treatment, induction soldering, and more.

Chains are generally metal links or rings used primarily for mechanical transmission and traction. They serve diverse industries including food production, electrical manufacturing, logistics, coating, electronics, and other applications. Their advantages include long-distance transmission capabilities and operational stability.

Many chains endure alternating loads such as torsion, bending, and impact forces during operation, with surface layers bearing higher stress than the core. Under friction conditions, surfaces experience continuous wear, necessitating high strength, hardness, wear resistance, and fatigue limits. Surface strengthening through induction quenching meets these requirements while offering minimal deformation and high productivity.

The fully automatic chain induction heat treatment equipment produced by Duolin includes:

• Loading and positioning device
• Quenching feed transmission (motor and driving wheel)
• Quenching liquid water tank transmission wheel
• Tempering and muffle furnace transmission wheel & incubator
• Chain tensioning device and its transmission wheel & counterweight
• Straight section tempering drive wheel
• Discharge drive (motor and drive wheel)
