Specifications--Rod type
The Rod Heating element is a resistance type silicon carbide heating element. The elements are rod shaped or tubular.
The Rod Heating element is a resistance type silicon carbide heating element. The elements are rod shaped or tubular depending on the diameter. They have a central heating section referred to as a hot zone and two terminal sections called cold ends. The cold ends are impregnated with silicon metal to lower their resistance. This. Causes them to, operate at a lower temperature. The extremities of the elements are metailized with aluminum to provide a low resistance contact surface to which the electrical connections are made with braided aluminum straps.Elements are described by giving the overall length, the heating section length, and the diameter. As an example, 43 x 24 x 1 is an element 43" overall with a 24" hot zone, and 1" in diameter.
Superior Performance
Rod Heating element will give you superior performance due to their high density approximately 2.4 gms/cc. This gives the element very slow aging characteristics and additional strength.Rod Heating element are interchangeable with all standard silicon carbide elements. They are offered in equivalent sizes and have almost the same resistance values. Before attempting to substitute the tubular or solid elements for spiral type elements, please contact us.Operating TemperaturesThe Rod Heating element can be operated at furnace control temperatures up to 3100 in an air atmosphere or inert atmospheres of argon or helium . In reducing atmospheres the maximum operating-temperature is 2500 .There is a protective coating of silicon dioxide on the silicon carbide. The hydrogen reduces this, coating and causes the element to deteriorate. Very dry or very wet hydrogen are both detrimental to long element life.
