Single Spiral Double Sic Heating Element Silicon Carbide Spiral For Furnace Sic Heater Electric

Sic Spiral Feature : 

Compared with other metal electric heating elements, it has the following unique advantages:

1. Strong acid resistance and oxidation resistance;

2. The surface load density is larger than the metal heating element, the heating is faster, and the thermal efficiency is higher.

3. Good heat and cooling resistance, small linear expansion coefficient;

4. High thermal conductivity;

5. High temperature, long life, normal air atmosphere, rod surface temperature can reach 1600℃, continuous service life can reach more than 2000h;

6. Easy installation and replacement;

7. A wide range of materials.

Sic Products Application : 

SiC heating elements are extensively used in the fields of metallurgy, ceramics, glass, machinery, analysis test, semiconductor,science & research and so on.

Packing & Shippment :

CS’s Silicon Carbide Products are carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.              

Use/Maintenance Methods :

1, silicon carbide rod texture hard and brittle, subject to severe vibration and impact easy to fracture. Therefore, extra care should be taken during transportation and handling should be handled lightly.

2. The length of the heating part of the silicon carbide rod should be equal to the width of the furnace. If the heating part extends into the furnace wall, it is easy to burn the furnace wall.

3. The length of the cold end of the silicon carbide rod should be equal to the thickness of the furnace wall plus the length of the cold end extension of the wall. Generally, the extension length of the cold end is 50 ~ 150mm, so as to cool the cold end and the connection fixture.

4. The inner diameter of the furnace through the silicon carbide rod should be 1.4 ~ 1.6 times the outer diameter of the cold end. The furnace hole is too small or the filling in the hole is too tight, and the high temperature will hinder the free expansion of the silicon carbide rod and cause the broken rod. When installed, the silicon carbide rod should be able to rotate 360 degrees freely.

Customize Requirements:
