The use of high temperature muffle furnace

The use of high temperature muffle furnace What is a muffle furnace? High temperature muffle furnace is a general heating equipment, also called high temperature box furnace. After unpacking, check that the muffle is intact and that the accessories are complete. General muffle furnace does not need special installation, just lay flat on the floor or shelf indoors. The controller should avoid vibration and should not be placed too close to the electric furnace to prevent the internal components from not working properly due to overheating.Influence of Brazing Vacuum Degree on Copper and Hafnium Brazed Joints 2. A thermocouple is inserted into the furnace for 20-50mm, and the gap between the hole and the thermocouple is filled with asbestos rope. It is best to use compensation wire (or insulated steel core wire) to connect the thermocouple to the control, pay attention to the positive and negative poles, do not connect them in reverse. 3. An additional power switch needs to be installed at the introduction of the power cord to control the main power supply. In order to ensure safe operation, the electric furnace and the controller must be reliably grounded.Oil cooler vacuum brazing 4. Before use, adjust the thermometer indicator to the zero point. When using the compensation wire and the cold junction compensator, the mechanical zero point should be adjusted to the reference temperature point of the cold junction compensator. When the compensation wire is not used, the mechanical zero point Set to zero scale, but the temperature indicated is the temperature difference between the measuring point and the cold junction of the thermocouple.Valve body vacuum heat treatment
