High-temperature vacuum sintering furnace is a commonly used sintering equipment, which can be used to manufacture a variety of materials. It is mainly composed of furnace body, the heating device and the vacuum system. The manufacturing process of high temperature vacuum sintering furnace includes furnace body manufacturing, process parameter setting and process operation. In this paper, we will discuss the influence of high-temperature vacuum sintering furnace on the manufacturing process through the study of the three aspects of furnace manufacturing, process parameter setting and process operation.

First of all, furnace body manufacturing is an important part of the manufacturing process of high temperature vacuum sintering furnace. The manufacturing quality of the furnace body directly affects the performance and life of the sintering furnace. A high-quality furnace body can provide a stable working environment, maintain good vacuum and energy transfer efficiency, thus improving the sintering effect. The material and structural design of the furnace body are the key to the manufacturing of the furnace body. Commonly used furnace materials include graphite, molybdenum and molybdenum alloys. Different materials have different heat resistance, thermal conductivity and corrosion resistance, and the selection of appropriate materials can improve the stability and durability of the furnace body. In addition, the structural design of the furnace body also needs to take into account the heating uniformity and cooling effect, in order to improve the quality of the sintered products and the effect of heat treatment.

Secondly, the setting of process parameters is also an important part of the manufacturing process of high temperature vacuum sintering furnace. Different materials and sintering processes require different parameters such as temperature, pressure and time for control. Reasonable process parameters can improve the physical properties of sintered products such as densification, strength and electrical conductivity. In the sintering process, temperature is the key parameter. The rate of temperature rise and fall, the holding time and the choice of high temperature all affect the structure and properties of the sintered products. In addition, gas pressure and vacuum are important parameters. Too high or too low pressure and vacuum will affect the densification and porosity of the sintered products. Therefore, reasonable setting of process parameters can improve the sintering effect of the sintering furnace and the quality of sintered products.

After that, the process operation is a part of high temperature vacuum sintering furnace manufacturing process that cannot be ignored. The standardisation and stability of the process operation have an important influence on the manufacturing process of the sintering furnace. Operators need to be familiar with the use of the sintering furnace and the operation process, and master the adjustment methods of the furnace and process parameters to ensure the normal operation of the sintering furnace. At the same time, the operator needs to differentiate the operation according to different materials and sintering processes. For example, for materials that are easy to oxidise, operators need to add anti-oxidation measures in the operating environment. Reasonable process operation can improve the service life and the working efficiency of the sintering furnace, thus improving the reliability and stability of the production process.

In summary, high temperature vacuum sintering furnace has an important impact on the manufacturing process. Furnace manufacturing, process parameter setting and process operation are not to be ignored in the manufacturing process. Reasonable furnace manufacturing and structural design can improve the stability and durability of the furnace, thus improving the sintering effect. Reasonable setting of process parameters can improve the quality and performance of sintered products. Standardised process operation can improve the reliability and stability of the sintering furnace. Therefore, the research and optimisation of the manufacturing process of high-temperature vacuum sintering furnace is of positive significance to improve the sintering effect and the quality of sintered products.
