Aerospace standard vacuum furnaces have a variety of options for heating methods, commonly including radiant heating, convection heating, and radiant convection heating. Each of these heating methods has its own characteristics and is suitable for different materials and process requirements.

Radiant heating refers to heating the workpiece through radiant heat transfer. Radiation heating in vacuum furnace is usually through the heating element (such as resistance wire, electric furnace sheet, etc.) generated by electromagnetic wave radiation to make the surface of the workpiece heated. This heating method has the advantages of fast heating speed, high energy utilization, uniform temperature, etc. It is suitable for the case of high requirements on the surface heating of the workpiece.

Convection heating is through the vacuum furnace gas or liquid medium to transfer heat, so that the workpiece is heated. Convection heating has the advantages of stable heating, uniform temperature, simple operation, etc. It is suitable for the workpiece with high overall heating requirements.

Radiation convection heating is a combination of radiation heating and convection heating, the use of two heating methods to complement each other, so that the workpiece to achieve more uniform heating effect. This heating method can quickly heat the surface of the workpiece, but also can realize the overall heating, applicable to the complex nature of the material, the heating requirements of the process of demanding.

In addition to the above three main heating methods, aerospace standard vacuum furnaces can also be selected according to the specific process requirements of other heating methods, such as induction heating, microwave heating, plasma heating and so on. These heating methods also have a wide range of applications in the aerospace field, and can meet the heating needs of different materials and different processes.

In general, the aerospace standard vacuum furnace has various heating methods, and the selection of suitable heating methods can improve the heating efficiency and ensure the quality of the workpiece, which is an indispensable and important link in the research and production of aerospace field. In the future development, with the continuous progress of science and technology, the heating method of aerospace standard vacuum furnace will also continue to innovate and improve, and make greater contribution to the development and progress of aerospace field.
