Heat preservation treatment: When the target temperature is reached, keep a stable temperature and heat preservation time, so that the material can obtain the desired heat treatment effect. During this period, attention should be paid to the temperature uniformity in the furnace to avoid excessive temperature gradients.Vacuum Brazing solutions for Cutting and Grinding Tools Cooling process: After the heat treatment is completed, turn off the heating source of the tube furnace and perform proper cooling treatment. The cooling speed can choose natural cooling or auxiliary cooling method according to the requirements of the material to ensure that the material is cooled to a safe temperature.Alumina ceramic densely sintered Take out the material: After the material has cooled to an appropriate temperature, you can open the furnace door and take out the material carefully. Take care to avoid burns or other safety issues.The characteristics and working principle of vacuum heat treatment furnaces Cleaning and maintenance: After the heat treatment, the tube furnace should be cleaned and maintained to ensure the normal operation of the equipment and prolong its service life.Maintenance of Vacuum Carburizing Furnaces
