U-shaped silicon molybdenum rod is a type of U-shaped heating end and two cold ends that are sintered at high temperature through a special process. It has the advantages of high temperature resistance, rapid cooling and rapid heating, easy installation, high density, uniform red resistance, environmental protection, energy-saving, long working time, fast temperature rise, and short non-standard customized delivery cycle. Yancheng Yuheng Electric Heating Technology Co., Ltd. produces high-temperature electric furnace heating elements such as silicon carbon rods, silicon molybdenum rods, and stainless steel ceramic clips, Manufacturer of aluminum braided connecting tape.

The common sizes and models of U-shaped silicon molybdenum rods are: 3/6mm, 4/9mm, 5/10mm, 6/12mm, 7/12mm, 7/14mm, 8/16mm, 9/18mm, 10/18mm, 11/18mm, 12/24mm, etc. These are common models of silicon molybdenum rod electric furnace heating elements. Generally, the diameter of the cold end of the silicon molybdenum rod is twice the diameter of the heating end, and there may be errors in measurement, and the results need to be measured at multiple ends.

Silicon molybdenum rod is a pure resistive electric heating element that can be used in 220V and 380V circuits. Due to the characteristics of the silicon molybdenum rod material, the resistance of the silicon molybdenum rod is very small and can be almost ignored. The use of silicon molybdenum rod requires a transformer because it uses low voltage and high current. The voltage of the silicon molybdenum rod should be gradually increased during heating, and the full voltage should not be clamped at once, as this can easily burn the silicon molybdenum rod.

Silicon molybdenum rod heating element is a high-temperature resistant resistance heating element made based on molybdenum disilicide. When used in a high-temperature oxidation atmosphere, a bright and dense quartz (SIO2) glass film is produced on the surface, which can protect the inner layer of the silicon molybdenum rod from oxidation. The resistance of silicon molybdenum rod electric heating elements increases with increasing temperature. When the temperature remains constant, the resistance value is stable. When in a cold state, the resistance of the element can be ignored and does not change with the length of use. New and old electric heating elements can be mixed for use.

It is recommended that customers choose larger manufacturers and experienced and powerful manufacturers when selecting silicon molybdenum rods and silicon carbon rods for electric furnace heating elements. This is because some small workshop style manufacturers do not have corresponding processing and testing equipment, resulting in inconsistent specifications of silicon molybdenum rods, low operating temperatures, and high impurity content, which affects customer use. We are a manufacturer specializing in the production of high-temperature electric furnace heating elements such as silicon molybdenum rods and silicon carbon rods. Production equipment is constantly being updated, with experienced technicians and researchers.
