Double Helix 1550 ℃ Silicon Carbide Heating Element For Industrial Smelting Furnace

General Description

First , the SCR , Double Spiraled SiC Heating Element , made of special high-density reaction-bonded Silicon Carbide , is a tube with both electrical connections on the cold end of the element . The hot zone is formed by cutting a double spiral slot , making the resistance higher than the cold end , and thus to reduce the cross sectional area and the current flows.

Second, the cold end is formed by cutting two longitudinal slots along the length of the tube . The SCR element is supplied with a ceramic collar cemented to the extremities of the cold end . And the cold end of the SCR element is flamed sprayed with aluminum with a distance of about two inches .

Third, flat braided-aluminum straps are held in compression with stainless steel clamps to the metallized area. The clamp is electrically insulated from the flat braid with high temperature insulation. The aluminum braid is 10 inches (254 millimeters) long and holes are provided for easy connection to the power supply.
