Precautions for operation and use of ボックス型抵抗炉

Do you know what you need to pay attention to when operating a box-type resistance furnace? Today, the editor summarizes the key points of operation, and hopes to help everyone after learning.

1. When using a box-type resistance furnace, do not adjust the temperature to the maximum controlled temperature of the resistance furnace, otherwise the resistance furnace may explode and other safety hazards.

2. Don’t cut off the switch when sampling: When sampling, be sure to cut off the switch, otherwise electric shock may occur. The temperature of the box-type resistance furnace is very high. Generally, you can feel the temperature of the resistance furnace at a distance of one meter from the box. Therefore, you must wear gloves when sampling, and if necessary, wear a certain amount of work clothes with good thermal insulation.

3. Close the furnace door heavily: Open and close the furnace door lightly when in use to prevent damage to the parts. The door block and high temperature cotton of the box-type resistance furnace are important parts of the electric furnace, but they are all vulnerable parts, which easily affect the insulation of the resistance furnace and the uniformity of the furnace temperature. Therefore, it should be light during use. Take it lightly.

Fourth, place the electric furnace in an excessively high working environment: The working environment of box-type resistance furnaces needs to be very stable, and high temperature environments are not allowed. Generally, the humidity of the resistance furnace should be below 80%. Excessive temperature or excessive humidity are the taboos of resistance furnaces.

In consideration of the life of the muffle furnace, it is necessary to push out the heating in time after the sampling is completed, otherwise the excessive temperature will melt the internal components, and the life of such a resistance furnace will be greatly reduced.
