DM Type Silicon Carbide Heating Elements consist of a hollow tubular heating section with thickened ends, designed for high-temperature industrial applications. Their composition leverages silicon carbide's exceptional material properties, including high density (3.2 g/cm³), extreme hardness (9.5 Mohs), and efficient thermal characteristics (specific heat of 0.17 kcal/kg). These elements operate effectively in temperatures ranging from 1200-1400°C, making them suitable for demanding environments like atmosphere retort furnaces, metal treatment, and ceramic production. The design prioritizes thermal efficiency, uniform heat distribution, and structural durability under continuous high-heat conditions.
