In the process of using the vacuum furnace, everyone has encountered the problem of carbon deposition. Today, the Heshenglong vacuum furnace will analyze some reasons for the carbon deposition in the vacuum furnace.
1. Long-term burning of charcoal;
2. The carbon controller fails;
3, long-term use of high carbon potential, the flow of rich gas is too large, easy to appear in the furnace carbon.
4, the atmosphere is not well controlled
5, the most easy to deposit carbon or methanol cracking is not enough
6, decomposition poor adsorption excess
If the radiant tube is carbonized, the consequences will be more serious. It is easy to cause the furnace temperature to rise or the temperature to rise slowly. Under such circumstances, He Shenglong told everyone that the vacuum furnace furnace carbon can effectively remove the carbon deposits on the anti-seepage carbon bricks and the radiant tubes. The method is that in the case where there is no product in the front and rear of the vacuum furnace, the temperature of the back chamber is preferably about 800 °C. Then first open the front door with a fire, then extinguish the fire; open the middle door for about 1 minute, then open the middle door for another minute after 5 minutes (this is repeated 3 times). The carbon in the furnace burns almost.
Now you know that the vacuum furnace should avoid the carbon deposits in the furnace and the treatment method of the carbon deposit in the furnace. Welcome to continue to pay attention to the Heshenglong vacuum furnace to provide you with more knowledge of the use and maintenance of vacuum furnaces.
