There are many kinds of insulation materials for carbon roasting furnaces. The following are some common types:
Ceramic fiber blankets: have low thermal conductivity, excellent thermal insulation performance and good flexibility. They can be cut and laid according to needs. They can effectively reduce heat loss. At the same time, they have certain thermal shock resistance and can adapt to the temperature changes in the roasting furnace.
Ceramic fiber modules: Generally pre-made into modules of a certain shape and size, easy to install, and can be quickly assembled into a furnace lining structure. It has good high temperature resistance, can maintain a stable shape and thermal insulation performance at high temperatures, and can withstand high heat loads.
Diatomite bricks: Made of diatomite as the main raw material, with an appropriate amount of binder added. It has low thermal conductivity and good high temperature resistance. It can maintain good structural stability at high temperatures, and has a good barrier effect on the heat in the carbon roasting furnace, reducing the heat dissipation outside the furnace.
Diatomite insulation coating: It is an insulation material that can be applied to the surface of the furnace body. It can form a uniform insulation coating with good adhesion and insulation performance. This coating is easy to apply and can be used for local repair of the furnace body or insulation treatment of small roasting furnaces.
Aerogel felt: It is a new type of high-efficiency insulation material with extremely low thermal conductivity and excellent thermal insulation performance. It is light, soft and bendable, easy to install on furnace parts of various complex shapes, can significantly reduce heat loss, and also has good waterproof and moisture-proof properties.
Aerogel composite board: Aerogel and other reinforcing materials are composited into boards, which not only retains the excellent insulation performance of aerogel, but also improves the strength and durability of the material. This composite board is suitable for key parts of carbon roasting furnaces with high requirements for insulation performance, such as furnace doors, furnace roofs, etc.
