What should be noted when selecting a vacuum furnace?

A vacuum furnace is a device that uses a vacuum system to discharge some substances in a specific space, so that the pressure inside the furnace chamber is less than a standard atmospheric pressure, thereby achieving a vacuum state in the furnace chamber. Vacuum furnace is a widely used equipment in various industrial fields, characterized by heat treatment in a vacuum environment. What should be noted when choosing a vacuum furnace?

① Application requirements: First, determine your application requirements, including workpiece size, material type, heating temperature range, etc. Different applications may require different types of vacuum furnaces, for example, some require high-temperature treatment, while others require low-temperature protection.
② Performance of vacuum furnace: It is necessary to choose a stable and reliable vacuum furnace to ensure its heating operation is becoming safer. This requires consideration of factors such as the ultimate vacuum degree of the vacuum furnace, vacuum leakage rate, pumping time, heating rate, cooling rate, and uniformity of the temperature zone inside the furnace.
③ The purpose of vacuum furnace: Choose a suitable vacuum furnace according to your own experimental requirements. For example, if high alloy steel needs to be processed, it is necessary to choose a vacuum furnace that can meet the tempering temperature requirements of high alloy steel.
④ The structure and quality of vacuum furnaces: It is necessary to choose a vacuum furnace with a reasonable structure and reliable quality. Pay attention to factors such as the material of the heating element, wiring method, insulation material of the vacuum furnace, as well as the size of the furnace and the specifications and models of the vacuum gauge.
⑤ Control system of vacuum furnace: The control system of vacuum furnace is its core part, ensuring its reliability and completeness. The control system should have monitoring, fault display, and recording functions. For vacuum furnaces with high usage loads, remote monitoring functions are required.
⑥ Vacuum degree requirement: Determine the required vacuum degree based on process requirements and material characteristics. Some applications require ultra-high vacuum environments, while others can be processed at relatively low vacuum levels.
⑦ Heating methods: Vacuum furnaces can use various heating methods, including resistance heating, insulation screen heating, graphite heating, etc. Choosing the heating method that suits your needs can improve process efficiency and product quality.
⑧ Safety and operational convenience: Consider the safety and operational convenience of vacuum furnaces, including automation control systems, safety monitoring functions, etc.
⑨ Energy consumption and maintenance costs: Considering the energy consumption and maintenance costs of vacuum furnaces, selecting equipment that can provide high efficiency and easy maintenance can reduce production costs.
⑩ Manufacturer reputation and after-sales service: Choose reputable manufacturers and ensure timely after-sales service and technical support to ensure the stable operation of the equipment.
