Jinyu Silca SiC heating element is a type of non-metal high temperature heating device. These SiC

productsare made from fine quality green silicon carbide as its main raw material. The raw material is made

first in to a blank, followed by high temperature silication and recrystallization, and becomes high quality

stick shaped SiC electric heating devices. Compared with metal electric heating material, this type of non-

metal elements is featured of high operation temperature, anti-oxidization, long service life, little

deformation, easy installation and maintenance. Because of these advantages, SiC electric heating elements

is widely used in various industries that require high temperature electric furnaces and heating devices.

These typicalapplications include electronics, magnetic materials, powder metallurgy, ceramics, glass,

metallurgy and machinery.


We adopt new production process of cold end, so Jinyu Silca heating elements have excellent specific

rate of heat zone resistance and cold end resistance, saving energy, long life, avoiding over-temperature of

cold ends damaging furnace body.


Products specification: Rod type, U type, W type (Three Phase type), Solid Rod type, Spiral type, 5

piece type (dual hot zone). Sizes are available from Dia 12mm, 14mm, 16mm, 18mm, 20mm, 25mm, 30mm, 31.7mm

(1.25inch), 35mm, 38.1mm (1.5 inch), 40mm, 44.4mm (1.75 inch) to 54mm (2.125 inch) for all types.
1.SiC super heating elements Electric Characters
SiC super heating elements has a greater specific resistance. When it is heated in air by electrifying

until surface temperature of hot zone reaches 1050°C±50°C, its resistivity will be in the range of 600-

1400mm2/M. The resistance of SiC super heating element changes with increasing temperature. From room

temperature to 800°C, the curve of resitance-temperature is negative value and turns positive when the

temperature is above 800°C.

Surface load=rated power/surface area of hot zone (W/cm2)

The surface load has great relation with service life of the SiC super Heating Elements. Therefore, it is

necessary to strictly control the surface load within the limit range when heating. Overload is not

permitted.Given surface temperature of hot zone corresponding to furnace temperature, the allowed unit

surface load of hot zone is as the below chart.
