Characteristics of silicon carbide heating elements:
Silicon carbide is a ceramic material with relatively high electrical conductivity when compared to other ceramics. Elements are produced by pressing or extruding and then sintering.
Typical heating elements are rods or tubes, with diameters between 0.5 and 3 inches and lengths from 1 to 10 feet. They have metalized ends for electrical connections, and they often have both connections at one end, with two helical slots which stop short of the Other end, thus approximating a twisted hairpin form.
Due to its unique and excellent performance, U type silicon carbide rods are widely used in various electric kiln with furnace temperature of 600-1500 °C for metallurgy, electronics industry, kiln industry, chemical industry, metal heat treatment, powder metallurgy sintering, ceramics, science. Used in fields such as experiments. Silicon carbon rods are also used as infrared light sources on instruments, making them ideal for high temperature heating elements.
If it is matched with the automatic power supply system, it can obtain accurate constant temperature, and can automatically adjust the temperature according to the actual needs of the production process.
Application:
It has been widely used in the fields of national defense, machinery, metallurgy, lightening, ceramics, semiconductor, analytical laboratory, scientific research, etc. It has become the electric heating element of various electric furnace electric kiln. Tunnel kiln, roller kiln, glass kiln, vacuum furnace , muffle furnace, smelting furnace and all kinds of heating equipment, using silicon carbon rod heating is convenient, safe and reliable.
Also It is widely used in many high-temperature electric furnaces, electric kiln and electric heating equipment in electronics, magnetic materials, powder metallurgy, ceramics, glass, metallurgy and machinery industries.

Note on the use of silicon carbide heating rods:
1. When using silicon carbide rods, choose a reasonable surface load density and service temperature. The use temperature should be no more than 1650 ° C; use in harmful gas environment to prevent the silicon carbon rod from chemical reaction with harmful gases.
2. When replacing the silicon carbon rod, the silicon carbon rod should be selected to be close to the resistance of the silicon carbon rod running in the furnace. If necessary, replace the whole silicon carbon rod, which is beneficial to improve the service life of the silicon carbon rod. The silicon carbon rod, if the resistance value is appropriate, can also be used in the middle and later stages of the electric furnace operation.
3. Prevent the silicon carbide rod from splashing on the molten metal. Splashing the molten metal is likely to cause the broken rod.
4. Prevent alkali, alkaline earth metals and alkaline oxides from corroding silicon carbon rods.
5. Always observe whether the readings of the ammeter, voltmeter and thermometer are normal; whether the cold end clamp is loose, oxidized black or sparked; whether the silicon carbon rod is broken; whether the red heat of the silicon carbon rod heating part is uniform.
