Share the precautions for the use of vacuum atmosphere furnace

Today, Nuotai technology will share with you the precautions for the use of vacuum atmosphere furnace

1. Firstly, before the vacuum atmosphere furnace heats up, the cooling pipe must be connected with refrigerant for circulating cooling. When the temperature is not high, water can also be used for circulating cooling. When heating up, pay attention to the atmosphere protection or vacuum state. It is strictly prohibited to heat up without atmosphere protection and non vacuum state or put objects with gas expansion.
2. When vacuumizing in the furnace, it shall not exceed the pointer scale of two grids (if it exceeds the scale of two grids of vacuum gauge when vacuumizing, it will damage the vacuum atmosphere furnace). When the pointer of vacuum gauge drops close to two grids, stop vacuumizing, fill in Sui gas, make the pointer return to 0 or slightly greater than 0, then extract and inflate, and repeat for 3 to 5 times to ensure that the protective gas in the furnace cavity has a certain concentration.
3. When the workpiece does not need atmosphere protection, the vacuum atmosphere furnace should be connected with the air inlet pipe, filled with falling gas, slightly release the air outlet valve, close the air outlet valve when the filled gas is greater than the furnace volume, and observe that the pressure gauge should be greater than "0" and less than two grids.
4. The shell of vacuum atmosphere furnace must be effectively grounded to ensure safe use; The furnace body shall be placed in a well ventilated room, and inflammables and explosives shall not be placed around it; The atmosphere furnace shall be closed 15 minutes after the end of operation, so as to facilitate the heat dissipation of the furnace body.
The above is the structure, composition, characteristics and precautions of the vacuum atmosphere furnace compiled by Nuotai. I hope it can be helpful to you. Zhengzhou Nuotai technology has technicians who have been engaged in electric furnace design for many years. Most of the products can be self-developed. It can provide customers with vacuum atmosphere furnaces of various specifications and models, and can also provide customization of various parts. If necessary, you can leave a message on our website or call customer service for detailed consultation.
