How to operate the box-type resistance furnace to be safe

In the electric furnace industry, the box-type resistance furnace is a national standard energy-saving electric furnace for periodic operation. It is also designed for universities, research institutes, laboratories, and industrial and mining enterprises for ceramics, metallurgy, electronics, glass, chemicals, machinery, and refractory materials. , New material development, special materials, building materials, metals, non-metals and other chemical and physical materials for sintering, melting, analysis, and production of special equipment. If you want to make use of the high efficiency of the resistance furnace, correct operation is the key. During its use, especially the following actions, absolutely must not be done.

1. The box-type resistance furnace is placed in an excessively high working environment: the working environment needs to be very stable, and high-temperature environments are not allowed. Generally, the upper limit of the temperature of the resistance furnace is 50℃, and the humidity should also be in percent Below 80, too high temperature or too humid environment are all taboos for resistance furnaces.

2. Close the box-type resistance furnace door with too much force: the furnace door should be opened and closed lightly during use to prevent damage to the parts. Furnace door block firebricks and furnace mouth high-temperature cotton are important parts of electric furnaces, but they are all vulnerable parts, which easily affect the heat preservation of the furnace and the uniformity of the furnace temperature. Therefore, handle them with care during use.

3. Do not cut off the switch during sampling: When sampling, the switch must be cut off, otherwise an 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. In order to consider the life of the resistance 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, so that the life will be greatly reduced.

4. Adjust the temperature to the maximum control temperature of the box-type resistance furnace: Remember, never adjust the temperature to the maximum control temperature of the resistance furnace, otherwise the resistance furnace may explode and other safety hazards.
