In which main fields can silicon carbide furnace tubes be used?
In fact, silicon carbide is a synthetically produced carbon-based compound typically formed by passing an electric current through a mixture of carbon and silica at high temperatures of around 2,000 degrees Celsius. Silicon carbide furnace tubes boast numerous advantages, including high strength, excellent wear resistance, extreme material hardness, superior corrosion resistance, and outstanding high-temperature strength. As a result, they are widely used in various wear-resistant and high-temperature components. At room temperature, silicon carbide behaves as a semiconductor with impurity-induced conductivity. The higher the purity and the higher the temperature, the lower the resistivity. Moreover, its electrical conductivity varies depending on the type and concentration of impurities present. Silicon carbide also exhibits favorable properties such as good hydrophilicity and strong far-infrared radiation capabilities.

However, the impact of fouling on radiation tubes inside the furnace on heating power has yet to receive sufficient attention. Factors affecting thermal power include: Fouling on the radiation tubes within the furnace chamber degrades their heat-transfer performance. To meet production process requirements, it is necessary to raise the furnace chamber temperature, increase fuel consumption, and elevate the furnace wall temperature.

What is the working principle of an electric heating radiant tube?
An electric radiant tube is a device that converts electrical energy into thermal energy to heat a substance. When the heating tube is operating, a low-temperature fluid medium enters its inlet port under pressure and flows along specific heat-transfer channels within the electric heating container. The fluid thermodynamic principle underlying the design of air electric heating tubes ensures that the high-temperature thermal energy generated by the electric heating elements inside the tube is carried away along a predetermined path, thereby raising the temperature of the heated medium within the tube. At the outlet of the electric heating tube, the medium reaches the high temperature required for the process.

How do you install an electric heating radiant tube?
1. The rigid supports at both ends of the electric radiation tube must not be fixed, to prevent the radiation tube from being crushed due to adverse external forces from mechanical equipment. 2. The porcelain sockets at both ends of the electric radiation tube should be matched as flexibly as possible with the corresponding parts of the mechanical equipment; the radial and circumferential clearances should be no less than 1–3 mm. If a ductile clamping method is used, it is also necessary to ensure that there is sufficient thermal expansion space between the tube body and the rigid support.
