Abstract

Double-helix silicon carbide rod provides a non-metallic high-temperature heating element. It is a hollow long strip structure. One end is divided into two parts, which are conductive ends. Extending to the other end, they are intertwined with each other to form a heating section with a double-helix structure. The top end is closed. It is conical, and the conductive end is provided with two strip-shaped metal electrodes with a semi-arc cross-section, and a metal wire is arranged in the double helix structure of the heating section, and the two ends of the metal wire are respectively connected with the two metal electrodes. There is a ceramic rod inside the spiral silicon carbide rod. The part of the ceramic rod located in the heating section is cylindrical, and the part located in the conductive end is in the shape of a sheet, which separates the two metal electrodes and extends outward, and is stuck between the two parts of the conductive end. between. The invention has reasonable design, convenient use and stable structure.

Description

technical field [0001] The invention belongs to the field of high-temperature components, in particular to a double-helix silicon carbide rod. Background technique [0002] Silicon carbide rod is made of high-purity green hexagonal silicon carbide as the main raw material, processed with some ingredients, and then sintered at a high temperature of 2200 ° C. It is a non-metallic high-temperature electric heating element with various shapes such as rods and tubes. . Silicon carbide rods have high service temperature, high temperature resistance, oxidation resistance, corrosion resistance, fast temperature rise, and long life. Strong, can also be matched with automatic electronic control equipment, can obtain accurate constant temperature, and can automatically adjust the temperature according to the curve according to the needs of the production process. It is easy to use, safe and reliable. It has been widely used in high-temperature fields such as electronics, magnetic mat...
