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.Correct use and maintenance of vacuum brazing furnaceWhen
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)Influence
of Vacuum Brazing Process on Microstructure of Tungsten and Steel 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.Research
on Sintering Technology of Silicon Carbide Ceramic Material 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.Effect
