The box type electric furnace is characterized by fast heating speed and can also be adjusted. It can be programmed to meet the requirements of 30-50 sections of continuous temperature control and constant temperature. It has its own functions of switching interference and over temperature alarm. High precision temperature control, integrated structure, full door design, furnace door thickening and reinforcement treatment, in order to prevent deformation. The appearance is treated with anti temperature and anti-corrosion paint. Beautiful appearance. Next, let's talk about the operation steps of the box type electric furnace.
1. Operators of box type electric furnace must wear necessary protective equipment. For example: work clothes, thermal gloves, anti strong light goggles.
2. All kinds of operation tools should be prepared. It is forbidden to use cracked, faulty or inapplicable tools. The fire extinguisher should be kept at a fixed position beside the quenching tank.
3. Deliver the workpiece to be treated to the appropriate position beside the furnace, place it neatly, and do not stack too high to prevent damage.
4, connect the power of the box type electric furnace, then switch the power switch of the box type electric furnace to the ON level, and set the parameter value on the temperature controller. Of course, the upper temperature display switch must be turned on, and then adjusted to the required value.
5. Turn the heating switch to the on position to make the lower temperature of the box type electric furnace enter into the automatic ignition heating program. At this time, the box type electric furnace will beep. Don't panic. It is the normal working sound of the buzzer. The furnace began to heat up automatically.
6. After use, turn off the power of the furnace and controller.
There are also many matters needing attention in the operation of box type electric furnace. That is, never adjust the temperature to the temperature controlled by the resistance furnace, otherwise the resistance furnace may explode and other safety hazards. When sampling, the switch must be cut off, otherwise electric shock may occur. The temperature of the box type electric furnace is very high, generally one meter away from the box can feel the temperature of the resistance furnace, so when sampling, gloves should be worn, and if necessary, work clothes with good heat insulation performance should be worn. In order to consider the service life of the box type resistance furnace, it is necessary to push out the heating in time after the sampling, otherwise the too high temperature will melt the internal parts, so the service life of the box type resistance furnace will be greatly reduced.
The working environment of box type electric furnace needs to be very stable, and high temperature environment is not allowed. Generally, the high temperature of electric furnace is only allowed to be 50 degrees, and the humidity should be below 80 percent. Too high temperature or too wet environment is the taboo of electric furnace. In case of fire, cut off the power immediately, use sand or carbon dioxide and carbon tetrachloride extinguisher to extinguish the fire, and prohibit the use of conductive water such as water or foam extinguisher.
