The difference between electric heating silicon molybdenum rod and electric furnace wire

       Silicon molybdenum rod is a resistive electric heating element, made on the basis of molybdenum disilicide, high temperature resistance and oxidation resistance. When used in a high-temperature oxidizing atmosphere, a bright and dense quartz (SiO2) glass film is formed on the surface, which can protect the inner layer of the silicon-molybdenum rod from oxidation. The silicon-molybdenum rod element has unique high-temperature oxidation resistance. The use of silicon molybdenum rods must be equipped with a controllable cabinet. Strong mechanical, easy to break during transportation.

        The electric furnace wire is made of high-quality iron-chromium-aluminum and nickel-chromium electric heating alloy wires as raw materials. The power of the furnace wire is controlled by a computer and is wound into a high-speed automatic winding machine. It is also used in everyone's life. It is characterized by high temperature resistance, fast heating, long service life, stable resistance, small power deviation, uniform pitch after stretching, and bright and clean surface. It is widely used in small electric furnaces, muffle furnaces, heating and air conditioning equipment, various ovens, electric heating tubes and household appliances, etc. When the electric furnace wire is at a high temperature, it is prone to oxidation reaction and burn out.

The main differences are:

1. Operating temperature range:

Silicon molybdenum rods are generally used at a temperature of 1000 ℃-1750 ℃ ??　 silicon carbide rods are used at 800 ℃-1500 ℃, electric furnace wire is controlled at 200 ℃-1200 ℃

2. Properties Use silicon-molybdenum rods and silicon-carbon rods must use a silicon controlled voltage regulator to adjust the rated voltage of the electric furnace to control the temperature of the furnace. The electric stove wire can not be equipped.

3. For repairing, the electric furnace wire often breaks. People often connect the broken ends and use such joints to produce higher resistance, so it will break after a short time. Take a piece of thick copper wire or aluminum wire, bend both ends of the wire, and wind it around the electric stove wire. This kind of connection does not produce high resistance and is more durable. However, after the silicon carbide rod and the silicon molybdenum rod are broken, they cannot be repaired, which seriously affects the power and heat problems of the furnace.

      With the rapid development of science and technology in China, silicon molybdenum rods are becoming more and more important for high temperature materials, especially in metallurgy, new materials, aerospace and other industries. Silicon molybdenum rods have

It has the effects of low thermal conductivity, high temperature resistance, high energy saving rate, and environmental protection.

Low thermal conductivity: The thermal conductivity of silicon molybdenum rod heating elements cannot be higher than 0.06W/m.K. The thermal conductivity of silicon molybdenum rods is only 0.03W/m.K, which is ten times lower than that of traditional high-temperature materials, and the efficiency of heat insulation and heat preservation can reach about 90%.

High temperature resistance: The high temperature resistance of silicon molybdenum rods can reach 1800°C, far surpassing other heat-resistant materials.

High energy-saving rate: The silicon-molybdenum rod has a long service life, which is more than 30% more efficient than traditional coal burning, and its service life is also beyond the reach of coal. Now many pottery manufacturers in Sichuan have replaced them with electric heating hybrid kilns and use them uniformly

Silicon molybdenum rods are used as components to reduce production costs and improve environmental protection.

Green and environmental protection: Compared with the use of coal, the silicon molybdenum rod electric heating element is used and adjusted with the control cabinet, and there is no volatile gas or debris. Silicon molybdenum rods are processed from pure inorganic materials, which are non-toxic and harmless, without any volatilization at high temperature and normal temperature.
