| Strictly follow the computer program to operate and start the operation, turn on the main heating power supply (one, two, three, and four zone heating switches) respectively, and keep the continuous heating time for 6 hours. That is: 1 hour at 150 degrees, 1 hour at 300 degrees, 1 hour at 450 degrees, 1 hour at 550 degrees, half an hour at 700 degrees, half an hour at 800 degrees, half an hour at 50 degrees per liter above 800 degrees.Maintenance of Vacuum Carburizing Furnaces When the temperature of the quenching furnace reaches above 200 degrees, the cooling water at the furnace mouth should be turned on (considering water saving, as long as there is a small amount of flow, the water outlet should be 70 degrees)Applied Crack Repair Technology of Vacuum Brazing When the temperature of the quenching furnace reaches above 300 degrees, the mesh belt is turned on. When the temperature of the quenching furnace reaches 500 degrees, turn on the water circulation pump to keep the water curtain cooling in the water seal tank at the exit of the furnace.Vacuum carburizing process of transmission gear When the temperature of the quenching furnace reaches 800 degrees, it is necessary to supply methanol and provide protective gas to the furnace (pay attention to the ignition situation to prevent explosion in the furnace), and adjust the flow rate of the flow agent. Adjust the operating frequency of the mesh belt according to the process requirements.Vacuum Heat Treatment of Carbon Boron Steel Fasteners https://www.vacfurnace.com/technology-frontiers/maintenance-of-vacuum-carburizing-furnaces/
