U-Shaped Silicon Carbide Heater For Electric Furnace 1550 ℃
U-Shaped Silicon Carbide Heater For Electric Furnace 1550 ℃
General Description:
Made of high-density recrystallized silicon carbide, a U Shape Silicon Carbide Heating Element is manufactured by welding two carefully-matched SiC rods with 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 electrical connections made using flat aluminum braids held in compression to the circumference by a stainless steel spring clamp.
Since a U Shape Silicon Carbide Heating Element is composed of two ED Silicon Carbide Heating Elements sharing a cold end, it can be connected by the power cord at one end of the furnace. 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 ED or DB 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.
