Vacuum atmosphere furnace is one of our company's main products. What are the obvious advantages of vacuum atmosphere furnace? Let's take a look together to facilitate customers to better understand vacuum atmosphere furnace.
Vacuum atmosphere furnace reduces harmful components in the atmosphere (water, oxygen, nitrogen) The negative impact on the product, such as reducing the water content in electrolytic hydrogen to -40 ℃, is quite difficult, and a vacuum degree of 133pa is equivalent to a dew point of -40 ℃, so obtaining such a vacuum degree is not difficult. In order to control the atmosphere inside the furnace and maintain the pressure inside, the working space inside the furnace should always be isolated from external air to avoid air leakage and inhalation. Therefore, sealing devices are required for the furnace shell, masonry, furnace door, and all external connecting components such as fans, thermocouples, radiation tubes, push-pull devices, etc
During the vacuum sintering process, in order to improve the heating speed and temperature uniformity of the vacuum atmosphere furnace, an appropriate amount of gas (inert gas or hydrogen) can be injected into the furnace during the initial sintering stage. The circulating gas cooling method can also improve the cooling rate of vacuum sintering. To prevent resonance peaks from contaminating the vacuum system, the briquette should be pre burned before vacuum sintering to remove resonance peaks
