How can atmosphere sintering furnaces improve product sintering quality?

Atmosphere sintering furnace is a widely used equipment for sintering process of metallic and non-metallic materials. In the sintering process, the atmosphere sintering furnace can implement a specific heat treatment process on the workpiece to improve the mechanical, physical and chemical properties of the material. Atmosphere sintering furnace how to improve product sintering quality? Vacuum sintering furnace editorial below to speak specifically.

When operating the atmosphere sintering furnace, we can take a series of measures to improve the sintering quality of the product.

Firstly, we need to pay attention to the protection of the furnace chamber. In the sintering process, it is very important to keep the sealing of the furnace chamber. Poor sealing of the furnace chamber will lead to gas leakage from the combustion process in the atmosphere sintering furnace, thus destabilising the combustion atmosphere and affecting the sintering quality of the workpiece. Therefore, we need to check and maintain the sealing of the furnace chamber frequently to prevent gas leakage.

Secondly, we need to control the composition of the sintering atmosphere. The composition of the sintering atmosphere directly affects the sintering quality of the product. In the atmosphere sintering furnace, the commonly used atmospheres are reducing atmosphere, oxidising atmosphere and inert atmosphere. Different materials require different atmospheres to implement the sintering process. We need to control the composition of the sintering atmosphere according to the specific process requirements in order to improve the sintering quality of the products.

In addition, sintering temperature is one of the key factors affecting the sintering quality. The sintering temperature has an important influence on the grain growth of the product as well as the solid phase reaction. Therefore, we need to strictly control the sintering temperature in the sintering process. On the one hand, maintaining a suitable sintering temperature can promote the growth of the product grain and improve the density and mechanical properties of the product; on the other hand, too high or too low a sintering temperature will lead to a decline in the quality of the product. Therefore, we need to choose the appropriate sintering temperature to implement the sintering process according to the specific material and process requirements.

In addition, sintering time is also an important control parameter. Too short a sintering time may lead to incomplete sintering of the material, while too long a sintering time may lead to excessive grain growth of the product. Therefore, we need to control the sintering time according to the specific material and process requirements to ensure the sintering quality of the product.

In addition, we can also take some other measures to improve the sintering quality of the product. For example, the workpiece can be pre-sintered to improve the sintering density of the product; appropriate vibration measures can be taken to promote the arrangement of the material particles and the sintering process; you can choose the appropriate sintering auxiliary to improve the sintering quality of the product and so on.

In short, when using the atmosphere sintering furnace for process sintering, we need to pay attention to the protection of the furnace chamber, control the composition of the sintering atmosphere, strictly control the sintering temperature and sintering time, and take other appropriate measures to improve the quality of sintered products. In this way, we can get products with good sintering density and mechanical properties.
