Widely applicable for nitriding treatments of various products, including hydraulic components, wind turbine gear rings, engine crankshafts, mold surface enhancement, clutch friction plates subjected to nitriding, and corrosion-resistant nitrided parts. It can achieve nitriding and soft nitriding processes tailored for a range of applications, such as hard nitriding, soft nitriding, and post-oxidation treatments.

The treatment line is high in automation level and consistency of quality of product. The complete quenching line is formed up by automatic loader, roller hearth heating furnace, fully automatic press quenching machine, oil blowing device, washing machine, parts stacking machine, tempering furnace, forced hot press, unloading device and control system.

The roller hearth hot stamping production line for automotive high-strength steel is a widely applied and technically mature production line in the field of automotive body component manufacturing, especially for the hot stamping process of ultra-high-strength steel (UHSS).

The salt quenching roller hearth furnace developed by Yajie is a new generation salt quenching equipment, adopts Yajie many new patents, widely used for bearing industries, automobile parts industries processed by atmosphere salt quenching Martensite and Bainite quenching.
