High quality 1600c ED/DB/U/W/SC/SCR/UX type silicon carbide heating rods

1.Description of silicon carbide heating rods

1) Non-metallic heating element, based on material of high quality green silicon carbide

2) Compared with metal, SiC heater is characterized by anti-oxidation, corrosion resistance, long service life, deformation, easy installation and maintenance.

3) Widely used in multiple high temperature furnace(magnetic material, powder metallurgy, ceramic, glass, metallurgy and mechanical used) and other electric heating devices

4)SiC heater can be used in air atmosphere without any protect atmosphere.

We make U, W, ED, DB, SCR, SC, UX type , also can be customizable

The diameter of heating element are 8mm, 10mm,12mm, 14mm, 16mm, 18mm, 20mm, 25mm,30mm,35mm, 40mm, 45mm, 50mm and so on.

2. Physical properties of silicon carbide heating rods

Specific gravity	2.6~2.8g/cm3	Bend strength	>300kg
Hardness	>9MOH’S	Tensile strength	>150kg/cm3
Porosity rate	<30%	Radiancy	0.85

3.Electric properties of silicon carbide heating rods

Surface temperature of elements

4. Chemical properties of silicon carbide heating rods

1) Antioxidant property of elements

2)The effect of alkali and alkaline metal oxide to elements

The alkali and alkaline metal oxide will react with SiC at about 1300 °C and generate silicate, which calls alkali-chemical corrosion, and can influence the glowing of element evidentaly.

3)The effects to elements from melting metal

Some metals, such as cobalt, nickel, chrome and so on, can corrade the element in high temperature melting state and affect the service life of element.
