Product Description

The silicon carbide heating element is a kind of non-metal high temperature electric heating element. It is made of selected super quality green silicon carbide as main material, which is made intoblank, silicided under high temperature and re-crystallized. Compared with metal electric heating element, this kind of element is characterized by high-applied temperature, anti-oxidezation, anti-corrosion, long service life, little deformation, easy installation and maintenance. Therefore, it is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramics, powder metallurgy, glass and machinery, etc.

We adopt new production process of cold ends,so our SiC heating elements have excellent specific rate of heat zone resistance and cold end resistance, saving energy, long life, avoiding over-temperature of cold ends to damage the furnace body.

The product includes series: 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 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 25mm, 30mm, 31.7mm (1.25 inch), 35mm, 38.1mm (1.5 inch), 40mm, 44.4mm (1.75 inch) to 54mm (2.125 inch) for all types.

Electric Property

SiC heating elements has rather large specific resistance. When it is heated in air and the surface temperature of the hot zone reaches 1050, its resistance rate is 600-1400Ωmm2/m. Its resistance value changes as the temperature rises. From room-temperature to 800 is negative value, over 800 is positive value nature curve.

According to the furnace structure, correct choosing the elements surface load can make the elements use for a long time. The following picture shows the relations along with the furnace temperature. The element temperature and surface load are as follows when the heating elements are radiating without hindering condition. The shadow part is the surface load used usual temperature limits.

INSTALLATION

1) In order to keep furnace temperature and the load-bearing uniform of each element, before installation resistance distribution must be carried out. The resistance value deviation of each group should be below 10%

2) As the element is very brittle, be careful while install and maintain to avoid any damage.

3) When start to operate the furnace, raise voltage slowly and gradually, never give full load at one time, or the heating element will be damaged by over current impulse.

4) To use the elements, you should prepare the adjustable transformer or silicon controlled transformer, voltage meter, current meter and auto-control temperature meter etc. During the working, the voltage should be increased to maintain the furnace normal temperature because the resistance value will go up gradually caused by the oxidation of element. When the voltage get to the up limit of the transformer and the temperature is still low than the requirement, the furnace should be stopped, change the way of wire connection and then continue work.

5) In the course of long operation of the furnace, if any individual heating element is damaged owing to certain reasons and should be changed, you should replace it with proper one whose resistance value corresponds to that of the old one, never use a new heating element random. If the heating element is much damaged or its resistance value increases too much and cannot reach the furnace temperature, it is better to replace all the heating elements with new ones. Test and mark the resistance value of the old elements having been replaced (with voltmeter and ammeter) and distribute them in low temperature area.
