Daily Maintenance of High Temperature Muffle Furnace in Use

In the normal operation of high temperature muffle furnace, there are many details that need our attention. Good equipment maintenance habits can not only guarantee our life safety, but also prolong the service life of equipment and reduce the failure rate of equipment. According to experts'long-term research on high-temperature muffle furnace, several points are summarized as follows:

1. When high-temperature muffle furnace is used for the first time or is used again after long-term shutdown, it must be baked.

p>2. High temperature muffle furnaces and controllers must work in places where the relative humidity does not exceed 85% and there is no conductive dust, explosive gas or corrosive gas. When metal materials such as grease need to be heated, a large number of volatile gases will affect and corrode the surface of electrothermal components, which will destroy and shorten their life. Therefore, when heating, it should be timely prevented and properly sealed containers or appropriate openings should be excluded.

3. The high temperature muffle furnace controller should be limited to use in the ambient temperature range of 0-40 C. The number of opening furnace door should be reduced in the work, so as to avoid the rapid cooling and heat in the furnace and protect the furnace.

4. According to the technical requirements, check regularly whether the connection of electric furnace and controller is good or not, whether the pointer of indicator is stuck or not when moving, and check the error increase caused by magnet steel, demagnetization, wire expanding, fatigue of shrapnel and balance damage with potentiometer.

5. Furnace door should be lightly opened and lightly closed. Workpieces should be lightly handled to avoid damage to furnace mouth and hearth. When taking or placing the heated workpiece, the power supply should be cut off to ensure personal safety.

6. It is forbidden to pour liquid directly into the furnace. Iron chips and oxide scales in the furnace are often cleaned to keep the furnace clean

7. It is also necessary to keep the furnace clean and remove oxides in time.
