3 factors of uneven heating of electric heating tube

Electric heating pipes are used in many machinery industry equipment, and we often encounter some fundamental problems in the process of use. Another big problem with electric heating pipes is that the heating area of the electric heating pipes is unbalanced and uneven. The occurrence of such a situation will cause our object's heating zone to be unable to balance the heat and achieve the desired effect.

First, the choice of resistance wire:

When not in production, we must first solve a very important step, choose a good quality resistance wire. The quality of the resistance wire will directly affect the effect of the electric heating tube when it is used. Non-standard resistance wires may not be seen from the appearance. However, the efficiency can be found by using the low-quality materials, the electrical conductivity is not effective, some of the heat is good, and some of the heat is poor.

Second, the resistance wire gap is not uniform:

After choosing a good quality wire, we will follow the process of spinning. That is, the resistance wire is stretched and wound according to the design requirements. This process tries to ensure that the gap between the resistance wires is uniform. After the power is applied, the electric heating tube can ensure that the object is evenly heated. Otherwise, the temperature in the dense area is higher than the small density area. This process is very important.

3. Improper filling of magnesium oxide powder:

We all know that the filler inside the electric heating tube is magnesium oxide powder. Nowadays, most factories still use manual filling, which will result in the internal tightness not being grasped when filling. The overheating part will be slower and the loose part will be too loose. The fever is faster.
