Denova’s roller hearth T6/T7 heat treatment line is designed for continuous heat treatment of both thin-walled and thick-walled aluminum alloy structural components. The system supports air or water quenching according to different component characteristics and process requirements, and can be configured in U-shaped, I-shaped, or multi-level layouts to accommodate production flow, cycle time, and plant space requirements.

The system combines high-velocity forced-air and water quenching to accommodate different component thicknesses and performance requirements. Single-layer loading with lightweight baskets reduces thermal mass and accelerates heating, while high-intensity convection, pulse combustion, and a European-sourced self-recuperative combustion system improve heat transfer and energy efficiency. The line can also adopt a multi-level layout, with the aging furnace positioned above the solution treatment furnace, to maximize vertical space utilization.
Uniform furnace temperature control of up to ±3℃ supports stable T6/T7 heat treatment and consistent part performance.
Single-layer loading and lightweight baskets reduce unnecessary thermal mass, enabling significantly faster workpiece heating.
Reduced basket thermal mass lowers the energy required during heating, helping reduce energy consumption by more than 20%.
High-intensity convection, pulse combustion, and self-recuperative combustion technology improve thermal efficiency, reducing overall energy consumption by more than 15%.
With a multi-level layout, the aging furnace can be positioned above the solution treatment furnace, reducing floor space requirements by approximately 50%.
