Safety issues when using muffle furnace high temperature furnace
Muffle furnace is a common experimental basic equipment in laboratories and laboratories, and it is also one of the essential experimental equipment for basic experiments. In order to operate the box-type high-temperature muffle furnace more safely. When using, be sure to pay attention to the sequence of operating steps, so as to reduce the risk.
The newly purchased box-type high-temperature muffle furnace needs to be connected to the power supply first. If it is a three-phase 380V power supply, professional electricians must be connected to prevent electric shock accidents. Safety production is the first priority. If it is a box-type high-temperature muffle furnace that has just been purchased or has not been used for a long time, it must be baked. Pay attention to temperature control during the furnace process. First, slowly increase the temperature from 200°C to 600°C, and then Keep warm at 600℃ for more than two hours. In order to avoid a large number of small cracks in the furnace due to excessive heating. After the oven is finished, the furnace door cannot be opened until the temperature in the furnace is lower than 200°C. When opening the furnace door, it must be opened slowly and wear corresponding protective equipment (such as high temperature gloves, Goggles, etc.) to avoid burns caused by excessive temperature in the furnace. In order to reduce accidents, it is forbidden to fill inflammable and explosive liquids in the high-temperature furnace. , Do a good job in the maintenance and repair of the box-type high-temperature muffle furnace. If the heating element of the muffle furnace is found to be damaged and the furnace is dirty, it must be maintained and repaired in time.
