The secondary heating and quenching production line for wind turbine carburized gear roller hearth furnaces has been put into operation.


The secondary heating and quenching production line for wind turbine carburized gear roller hearth furnaces has been put into operation.

In December 2023, two secondary heating quenching production lines equipped with wind turbine gearbox roller hearth furnaces were successfully put into operation at the Nangao Gear Jinhu Factory! Each production line consists of two main furnaces, a quenching oil tank, and matching cleaning machines and tempering ovens, designed specifically for the secondary heating quenching of carburized gears used in wind turbine gearboxes with diameters up to 1.1 meters. This marks the second such production line to be commissioned at the Jinhu Factory, following the successful operation of the first roller hearth furnace-based secondary heating quenching line developed by Yajie Technology for Nangao Gear’s Lukou Factory back in 2021. Sister Line Compared to traditional manufacturing equipment, this production line features "three lows and one high" (low energy consumption, low carbon emissions, low operating costs, and high-quality thermal treatment process standards for products), helping the wind power industry master core manufacturing technologies for critical wind turbine components and enhancing the market competitiveness of wind turbine systems.
