Double-Layer Chain Conveyor T6/T7 Air-Quench Line

Denova’s double-layer chain conveyor T6/T7 air-quench line is developed for solution treatment, quenching, and artificial aging of thin-walled, large high-pressure die-cast structural components. Designed for continuous heat treatment production, the system provides controlled thermal processing and quenching for components with demanding requirements for dimensional stability and heat treatment consistency, while supporting efficient integration into high-volume production lines.

Core Technology

Double-Layer Chain Conveyor & Configurable Quenching System

The system combines a double-layer chain conveyor with single-layer workpiece loading and a configurable quenching system. High-velocity forced-air quenching or air-water mist quenching can be selected according to different component and process requirements, enabling controlled and uniform cooling throughout the T6/T7 heat treatment process. The double-layer conveyor arrangement utilizes vertical space to support continuous workpiece flow within a compact production layout.

Performance Benefits

Reduced Quenching Distortion Risk

High-velocity forced-air or air-water mist quenching provides rapid and uniform cooling, helping reduce thermal gradients and minimize distortion in thin-walled large structural castings.

Temperature Uniformity up to ±3℃

Optimized heating and circulation control help maintain furnace temperature uniformity within ±3℃, supporting consistent T6/T7 heat treatment results.

Up to 50% Reduction in Equipment Footprint

The double-layer chain conveyor layout makes full use of vertical space, reducing floor space requirements by up to 50% compared with conventional single-layer layouts.
