Electric heating vacuum annealing furnace has significant advantages in the field of material processing, but also has certain limitations. It is suitable for precision machining scenarios with high requirements for material surface quality and performance uniformity. The following is a detailed analysis of its advantages and disadvantages:

advantage

Good anti oxidation effect

The vacuum environment isolates active gases such as oxygen and nitrogen, effectively preventing oxidation, decarburization, or nitriding reactions of materials during heating. This is particularly important for commonly used materials in medical devices such as stainless steel and titanium alloys, which can ensure a smooth and pollution-free surface of the workpiece, reduce subsequent polishing and pickling processes, and lower material loss.

Accurate temperature control and stable performance

Equipped with a high-precision intelligent temperature program control system (such as PID control instruments), the heating and insulation programs can be set by oneself, and the temperature uniformity is good (within ± 5 ℃). By precise temperature control, the grain structure of materials can be optimized, and their ductility, wear resistance, and fatigue resistance can be improved, meeting the high requirements for performance stability of medical devices.

Strong ability to handle sensitive materials

Suitable for special materials with high atmosphere requirements (such as nickel titanium alloys and high-temperature alloys), it can be annealed under vacuum or protective atmosphere to avoid contact with complex gas components, reduce impurity pollution, and improve material purity.

Efficient and energy-saving, with reasonable design

Adopting full fiber energy-saving lining, the energy-saving effect is significant (more than 30% energy-saving compared to composite brick and concrete lining); Mobile furnace cover design accelerates cooling speed and improves equipment utilization. At the same time, the furnace body has good sealing performance, maintaining stable vacuum degree and reducing the risk of gas leakage.

Multi functional integration, strong adaptability

Supports multiple heating methods such as resistance heating and induction heating, with optional I/O monitoring, data recording, and other functions to meet different process requirements. In addition, the furnace size, shape, and atmosphere control method can be customized to flexibly adapt to various production environments and process requirements.
