if you need to manufacturer above products, please send us your own requirements, and drawing or pictures
Silicon Carbides heating elements are used in applications ranging in temperature from 600°C up to 1500°C in both air and controlled atmospheres. Although the type of atmosphere used will determine the maximum recommended element temperature. This kind of silicon carbide elements can be mounted either vertically or horizontally. The elements of our product are available in the range of 10 to 54mm diameter. The total length can vary up to 4500mm.
1) Types of Silicon carbide heater rod:
Main type: ED (straight ) ,DB (thin and thick ),SC(single thread), SCR(double thread ),U,W,UX etc.
2). Characteristics:
1)Low expansion coefficient ,
2)little deformation,
3)stable chemical property,
4)long service life ,
5)easy installation and maintenance.
3). Physical properties of silicon carbide SiC heating elements:
specific gravity | 2.6~2.8g/cm³ | bend strength | >300kg |
hardness | >9 MOH′S | Tensile strength | >150kg/cm³ |
porosity rate | <30% | radiancy | 0.85 |
4). Recommend surface load of silicon carbide heating elements:
Furnace Temp (°c ) | 1100 | 1200 | 1300 | 1350 | 1400 | 1450 |
Surface load of hot zone (W/cm²) | <17 | <13 | <9 | <7 | <5 | <4 |
5). Usage: It is widely used in various high temperature laboratory furnace and other electric heating devices, such as in the industries of magnet, ceramics, ceramics, power metallurgy.
6). Advices of using silicon carbide(SiC)heating elements:
1) In order to keep furnace temperature and the charges uniform of each element, before installation resistance distribution must be carried.
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.
7). Standard size of SiC heating element:
Dia(OD) (mm) | Length of hot zone(HZ)(mm) | Length of cold zone(CZ)(mm) | Overall Length(OL)(mm) | Range of Resistance(Ω) (ohms) |
