Vacuum induction melting furnace furnace maintenance methods

Vacuum induction melting furnace furnace maintenance methods

Vacuum induction melting furnace in use process, people usually encountered carbon deposit, today is to analyze the vacuum furnace hearth for everybody some of the reasons for carbon deposition.
1, long-term not charring;
2, carbon control instrument failure;
3, long-term use of high carbon potential, enriched gas flow open is too big, prone to furnace carbon deposition.
4, mood not good control
5, the most easy to carbon or inadequate methanol cracking
6, poor decomposition adsorption excess
Radiant tube carbon deposition, the consequences will be severe. Is very easy to cause the temperature rise will not come up or slow heating up. Such cases tell us vacuum furnace hearth burning carbon can effectively remove the anti-seepage carbon brick and the carbon deposition on the radiant tube. Method is vacuum furnace chamber didn't product before and after, under the condition of room temperature after the best at about 800 ℃. Then take steel opened the front door first, then put out steel; Open the door in 1 minute or so, and open the door a minute after 5 minutes (so repeatedly for 3 times). Carbon deposition is burning in the hearth.
Now you know the vacuum induction melting furnace in use process should avoid furnace carbon deposition as well as the chamber of a stove or furnace carbon processing method.
