Do not dry the immersion flange heating tube

The heating tube is divided into liquid heating tube and dry heating tube because of its own surface load design is different. Generally, the surface load of liquid heating tubes is much higher than that of dry heating. Since the liquid electric heating tube is heated in the liquid, the heat on the surface of the heating tube is easily absorbed by the liquid, so that the surface temperature of the heating tube is not too high, so the surface load design of the liquid heating tube can be higher. The immersed flange heating tube, because the working environment is in the air, the air itself has the negative effect of hindering heat conduction, so the surface load of the dry-fired electric heating tube is low. If the liquid electric heating tube is dry burning, the surface temperature of the heating tube cannot be dissipated immediately, the heating tube will cause the internal temperature to be too high, and the heating tube will burn out and cause serious tube burst.

It is widely used in the pre-firing, firing or heat treatment process of electronic products below 1050℃ in protective atmosphere or air, including thick film circuits such as conductive paste, resistance paste and dielectric, and the end of electronic components such as resistors, capacitors, and inductors. Silver firing, firing, glass insulator encapsulation of circuit cases, crystal oscillators, etc.

Alloy electric furnace wire is the most widely used and the largest heating material. Its disadvantage is that it is at a very high temperature (hot state) in the working state, and it is prone to oxidation reaction and burn out in the air; from the perspective of electrothermal energy conversion, the energy is lost due to the generation of visible light; the electric furnace wire is often When used in a spiral state, an inductive reactance effect will be generated when power is applied.
