When it comes to constructing a furnace, the materials used can vary widely depending on the type and purpose of the furnace.
Modern furnaces often incorporate a variety of materials to ensure durability, efficiency, and functionality.
Here are the seven key materials commonly used in furnace construction:
1. Stainless Steel
Stainless steel is frequently used in the heat exchangers of furnaces.
This material is prized for its corrosion resistance properties, which help extend the lifespan of the furnace.
2. Aluminized Steel
Aluminized steel is used for the construction of the frame, blowers, and burners.
Its properties make it ideal for withstanding the high temperatures and mechanical stresses found in furnaces.
3. Aluminum, Brass, and Copper
These metals may be used in specific components of the furnace.
Aluminum, brass, and copper offer unique properties that can enhance the performance of certain furnace parts.
4. Fiber Materials
Fiber materials are lightweight, soft in texture, and provide excellent insulation.
They are often used in parts of the furnace where insulation is crucial.
5. Refractory Brick Materials
Refractory brick materials are heavier and harder in texture.
They offer general insulation and are used in areas where durability and heat resistance are paramount.
6. Heating Elements
The heating element of the furnace is determined by the temperature requirements.
Resistance wire is commonly used for temperatures below 1200 °C.
Silicon carbide rods are used at temperatures between 1300°C-1400 °C.
Silicon molybdenum rods are widely used at temperatures between 1400°C-1700 °C.
7. Graphite and Refractory Metals
In liquid-fueled furnaces, the hot zone material is typically either graphite or refractory metal systems.
Graphite hot zone vacuum furnaces are known for their durability and low cost.
Refractory metal hot zone vacuum furnaces, such as those made from molybdenum and tungsten, are preferred for applications requiring a clean environment.
