Thermal ceramics are designed specifically to meet the needs of various key industries, like chemical production, petrochemical, and steel fabrication. The demand for this material is due to their excellent insulating qualities when used inside equipment such as an industrial convection oven.
Types of Thermal Ceramics:
Ceramics are inorganic, heat-resistant solids that are typically made up of compounds created from non-metallic and metallic elements. The various kinds of ceramics have different properties but they're generally hard, resistant to corrosion, and excellent insulators.
Here are three types of thermal ceramics:
- Ceramic Boards: These insulators are manufactured through wet vacuum forming and using top quality materials. They are developed using binders, bulk fibers, and fillers. Ceramic boards are durable, easy to cut, lightweight, and has great insulating properties. They come in different densities and can be customized to specific industrial convection ovens.
- Steelboards: This type of thermal ceramic board offers superior insulating and crushing capacities, as well as premiere strength. It should ideally be used in conjunction with 16” x 28” panels as this size helps reduce installation period. Steelboards also lowers energy consumption, has less steel penetration, more secure brick joints, and an extended shelf life. For this reason, these too are ideal for industrial convection oven equipment and other types of heat treating equipment.
- Developed or Formed Shapes: These are created for specific needs, like backup linings for industrial convection ovens, furnaces, combustion chambers, casting shapes, flue and stack liners, molten metal transfer, skid pipe insulation, sprue brushings, and tap-out cones, among others.
Reasons Thermal Ceramics Make Good Insulators
Stable Chemical Components: High-temp ceramics are chemically stable. The material's neutral acidity ensures it reacts to strong acid and alkali and gives off no reaction to water, oil, and weak alkali and acid. It also does not corrode aluminum, copper, or lead.
Preheating Process Not Necessary: Thermal ceramics have no need to be preheated so once it's installed inside the industrial convection oven, it can be used immediately. The material is also time and energy efficient.
Reduced Thermal Conductive Coefficient: Ceramics has a significantly lower thermal conductive coefficient. It actually only comes in as one-tenth of the conventional castable lining and refractory lining materials.
