Why is the dry-burning electric heating tube easy to break?

1. Whether the power design is reasonable, the power design of the normal dry-burning electric heating tube is 1kw in the length of 1m, and 1.5kw can be done if there is fan circulation. If the design exceeds the standard, the dry-burning electric heating tube will easily burn out.

 

2. The material of the electric heating tube is not selected correctly. The different working temperatures of the dry-burning electric heating tube use different materials.

 

Temperature resistance 300 degrees stainless steel 304, temperature resistance 500 degrees stainless steel 321, temperature resistance 700 degrees stainless steel 310S

 

3. The magnesium powder of the dry-fired electric heating tube should also be selected according to the temperature resistance. Some magnesium powders will lose their insulating properties as the temperature of the dry-fired electric heating tube increases, resulting in leakage.

 

4. The dry-burning electric heating tube must be equipped with an accurate temperature control system, and the temperature of the electric heating tube should not exceed the upper limit of temperature resistance in time.
