What are the types of heating elements in box furnaces?

Box furnace, also known as muffle furnace, is a universal heating equipment widely used in industries and departments such as electricity, coal, papermaking, petrochemicals, cement, agriculture and animal husbandry, pharmaceutical research, and teaching. Its heating element is the core component of a box furnace, used to convert electrical energy into thermal energy, thereby increasing the temperature inside the furnace. So what are the types of heating elements in box furnaces?9rZMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

1. Resistance wire (maximum heating temperature 1200 ℃)9rZMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Features: Resistance wires such as nickel chromium alloy wires have the characteristics of relatively low cost and stable heating. It has a high surface load, good oxidation resistance, and the generated alumina film after oxidation has good chemical resistance and high electrical resistivity. At the same time, it has good sulfur resistance, high strength at high temperatures, no magnetism, and good corrosion resistance except for sulfur atmosphere.9rZMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Application: Resistance wire is one of the common heating elements in box furnaces, widely used in various situations that require stable heating.

2. Silicon carbide rod (maximum heating temperature 1400 ℃)9rZMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Features: Silicon carbide rods are made of silicon carbide in the form of rods or tubes, which are recrystallized crystals of silicon carbide. It has high hardness, small deformation, resistance to sudden cold and heat, and does not react with acidic objects. It is antioxidant and suitable for high temperature environments. Silicon carbide rods have fast heating, high temperature resistance, and good antioxidant performance, but new and old rods should not be mixed. Long term use will increase the resistance value, and new silicon carbide rods need to be replaced if necessary.9rZMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Application: Silicon carbide rods are commonly used in box type resistance furnaces below 1400 degrees Celsius and are important components for high-temperature heating.
