Detailed explanation of the correct installation steps of the muffle furnace

The muffle furnace shell adopts a unique design of high-quality cold-rolled steel double-layer structure. The shell color paint is baked at high temperature, which is durable and equipped with an air cooling system. The furnace has a balanced temperature field, a low surface temperature, and a temperature rise and fall rate. Wait for the advantages quickly. The furnace generally works under natural atmosphere conditions, mostly internally heated, and uses refractory and thermal insulation materials as the lining. Mainly used for normalizing, annealing, quenching and other heat treatment of workpieces and other heating purposes. Installation Precautions:

1. The general muffle furnace does not require special installation, it only needs to be placed flat on a solid cement table or shelf indoors, and there should be no flammable and explosive materials around. The controller should avoid vibration, and the location should not be too close to the electric furnace to prevent internal components from not working properly due to overheating.

2. Insert the thermocouple into the furnace for 20-50mm, and fill the gap between the hole and the thermocouple with asbestos rope. Connect the thermocouple to the controller with the best compensating wire (or use insulated steel core wire), pay attention to the positive and negative poles, and do not connect them reversely.

3. At the power cord lead-in, an additional power switch needs to be installed to control the main power supply. In order to ensure the safe operation of the muffle furnace, the electric furnace and the controller must be reliably grounded.

4. Before using the muffle furnace, adjust the temperature controller to the zero point. When using the compensation wire and cold junction compensator, adjust the mechanical zero point to the reference temperature point of the cold junction compensator. When the compensation wire is not used, then The mechanical zero point is adjusted to the zero scale position, but the temperature indicated is the temperature difference between the measuring point and the cold junction of the thermocouple.

5. Adjust the set temperature to the required operating temperature, and then turn on the power. Turn on the work, the box-type resistance furnace is energized, and the input current, voltage, output power and real-time temperature are displayed on the control panel. As the internal temperature of the electric furnace increases, the real-time temperature will also increase. This phenomenon indicates that the system is working normally.
