With a total of seven patents to his name, Hilge's work has advanced the efficiency and effectiveness of heat treatment processes.
Latest Patents
One of Hilge's latest patents is a furnace designed for heating cylindrical charges, such as billets, rods, and tubes. This innovative furnace features a transportation facility equipped with a conveyance device that feeds the charges longitudinally through a treatment chamber. The design ensures that the cross-sectional shape of the chamber closely resembles that of the charge. Additionally, the transportation device includes a jacking mechanism that maintains the longitudinal axis of the charge at a consistent level, regardless of its diameter. The treatment chamber is equipped with nozzle outlets that direct heated gas jets radially onto the charge's surface. The system is designed to circulate hot gas from both ends of the chamber, with a ventilator positioned above the midpoint to enhance airflow.
Another significant patent involves an apparatus for heat treatment of metal pieces, such as billets and ingots. This apparatus utilizes hot gas impingement for pre-heating in a dedicated furnace, followed by forced hot air circulation in a holding furnace. This process ensures that the metal pieces are maintained at the desired heat treatment temperature for the necessary duration.
