  The following are some common refractory joint materials:

  1. Refractory mortar: Refractory mortar is a material used to fill and seal the gaps and joints between refractory materials such as refractory bricks and refractory boards. It is composed of refractory particles, binders and additives, and has good high temperature resistance and chemical corrosion resistance.

  2. Refractory rope: Refractory rope is usually made of ceramic fiber or glass fiber, which is used to fill and seal the gap between the furnace door, furnace cover and the furnace body and the pipeline. It has excellent high temperature resistance and flexibility, which can effectively prevent heat loss and gas leakage.

  3. Refractory glue: Refractory glue is a special glue used to connect and repair refractory materials. It can maintain adhesion and corrosion resistance in high temperature environments, and is suitable for splicing, repairing and fixing of refractory materials.

  4. Refractory belt: Refractory belt is a strip-shaped refractory material, usually made of ceramic fiber or silicate fiber. It is used to fill and seal joints of molten metal vessels, furnace tubes, and other high-temperature equipment, and has excellent high-temperature resistance and sealing properties.

  5. Refractory coating: Refractory coating is a material coated on the refractory surface to enhance its high temperature resistance and corrosion resistance. It can repair and protect the surface of refractory materials and prolong their service life.

  It should be noted that the selection of suitable fire-resistant joint materials should be evaluated according to actual application conditions and requirements. Different materials are suitable for different temperature ranges, media and process requirements, so it is best to consult a professional to determine the most suitable fire-resistant joint material.
