What are the precautions for the use of vacuum atmosphere furnaces?

Today, Protech company will share with you the precautions for the use of vacuum atmosphere furnaces

1. First of all, before heating up the vacuum atmosphere furnace, the cooling pipe must be connected to the cooling liquid for circulating cooling. When the temperature is not high, it can also be cooled by water circulating. When heating, attention should be paid to the atmosphere protection or vacuum state, and it is strictly forbidden to heat up in the absence of atmosphere protection and non-vacuum state or by placing objects with gas expansion.

2. When vacuuming in the furnace, the scale of the pointer should not exceed two scales (if the scale of the vacuum table exceeds two scales when the vacuum is drawn, it will damage the vacuum atmosphere furnace). Enter the inert gas, make the pointer return to 0 or slightly greater than 0, then pump and inflate, and reciprocate 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 to the air inlet pipe, filled with inert gas, slightly release the air outlet valve, and close the air outlet valve when the charged gas is larger than the furnace volume, and the observation pressure gauge should be greater than "0" less than two spaces.

4. The shell of the vacuum atmosphere furnace must be effectively grounded to ensure safe use; the furnace body should be placed in a well-ventilated room, and no flammable and explosive materials should be placed around it; the atmosphere furnace should be closed fifteen minutes after the end of work, in order to facilitate The furnace body dissipates heat.

The above is the structure and characteristics of the vacuum atmosphere furnace organized by Protech company and the precautions for use. I hope it can be helpful to everyone. Zhengzhou Protech Technology Company has technicians who have been engaged in the design of electric furnaces for many years. Most of the products can be independently developed. They can provide customers with various specifications and models of vacuum atmosphere furnaces, and can also provide customization of various parts.
