[0002] Ion carburizing and quenching furnaces can complete carburizing and quenching in a single heating process, greatly simplifying the process and improving production efficiency. Due to the use of ion implantation technology, carburizing is fast and quick, resulting in low energy consumption. Simultaneously, the equipment has a simple structure and low power consumption, further reducing production costs. During quenching, compressive internal stress is generated on the workpiece surface, which is beneficial for improving the workpiece's fatigue strength. Furthermore, the quenched workpiece has high surface hardness and good wear resistance. After the workpiece is placed in the ion carburizing and quenching furnace, the furnace lid is closed for the ion carburizing and quenching operation. The furnace lid is controlled by a lifting mechanism, and bolts are used to further secure it for improved stability.

A fixed support base for installation is fixedly connected to the lower left side of the carburizing multi-purpose furnace body. A lifting mechanism for lifting is installed on the upper end of the fixed support base. When the lifting mechanism is working, it will drive the fixed crossbeam, furnace cover and ventilation mechanism to lift, thereby facilitating the workers to process steel parts and put them into the loading frame inside the carburizing multi-purpose furnace body. When the carburizing multi-purpose furnace body is working, it will perform gas carburizing on the steel parts.
