DB ( Dumbbell ) Type Silicon Carbide

A thick end silicon carbide rod belongs to the field of electric heating elements, comprising two cold ends and a heating part located in the middle of the two cold ends. The end of the cold end far from the heating part is provided with a fixed section, and the outer peripheral side of the fixed section is provided with a white marking layer; The end of the cold end near the heating part is equipped with a conical transition section, and an annular groove is provided at the connection between the transition section and the cold end body; The heating part is a hollow tube, comprising a heating body, buffer sections and connecting sections located at both ends of the heating body, and the diameter of the heating body is smaller than that of the cold end; The buffer section is a conical shape consistent with the shape of the cold end transition section, and the inner diameter of the connecting section is equal to the outer diameter of the annular groove. The buffer section of the heating part is sleeved outside the cold end transition section, and the connecting section of the heating part is sleeved outside the annular groove of the cold end The present invention realizes the transition between the cold end and the heating part, reduces the stress on the cold end and the heating part, and reduces the possibility of breakage of the silicon carbide rod.
