Product Description
Product Description
U-shaped silicon heating element is manufactured by taking two carefully-matched SiC rods and welding a thickened silicon carbide bridge. This element provides for wiring both tail ends from one side of the furnace. The tail ends of the cold ends are metallized with aluminum, which can provide a low-resistance contact surface to the aluminum connection straps and clamps.
Since U-shaped silicon heating element is composed of two ED silicon heating elements sharing a cold end, it can be connected by the power cord at one end of the furnace. The surface temperature of heating part is 1500. It is mainly used in kilns with high furnace temperature and high temperature uniformity. Its characteristics are electricity saving and long service life.
In addition, a furnace with an energy saving structure can be built because the number of heating element holes on the furnace can be reduced compared with the U types. These elements are widely used as high-temperature heat sources for electric furnaces and for the firing of ceramic capacitors, ferrites and other electronic components.
