Silicon carbon rod is a rod-shaped, tubular non-metallic high-temperature electric heating element made of high-purity green hexagonal silicon carbide as the main raw material, processed according to a certain material ratio, and recrystallized and sintered by high-temperature siliconization at 2200 °C. The normal use temperature in the oxidizing atmosphere can reach 1450 °C, and the continuous use can reach 2000 hours.
Silicon carbon rod has high use temperature, high temperature resistance, oxidation resistance, corrosion resistance, fast temperature rise, long life, low temperature deformation, convenient installation and maintenance, and good chemical stability.
【Physical properties】:
Component texture: hard and brittle, resistant to cold and heat, not easy to deform at high temperature, other physical properties are as follows:
Thermal conductivity: 20 kcal/m·h·degree
Coefficient of linear expansion: 5×10-6(m/°C)
【Chemical properties】:
Silicon carbon rod has good chemical stability and strong acid resistance. At high temperatures, alkaline substances have an aggressive effect on them.
