ED Type Silicon Carbide Rod
The equal-diameter silicon carbide rods (ED type) are substitute products for the thick-end type silicon carbide rods. Their advantages are as follows:
Small End Resistance:
The current is evenly distributed on the rod body, reducing the aggregation of current at the ends, decreasing energy loss, improving the efficiency of converting electrical energy into thermal energy, and achieving remarkable energy-saving effects.
It also reduces the risk of overheating at the ends, thus prolonging the service life.
Long Service Life:
High-quality silicon carbide materials are used, which have high hardness, excellent high-temperature resistance. The melting point can reach above 2000°C, and they can maintain good mechanical strength and chemical stability in a high-temperature environment.
The equal-diameter structure design makes the thermal expansion and contraction relatively uniform, reducing the cracks and damages caused by the concentration of thermal stress.
They are commonly used in industries such as rare earth fluorescent powder, electronics, magnetic materials, powder metallurgy, and precision casting as heating elements for pusher furnaces, mesh belt furnaces, trolley furnaces, and box furnaces.
