Composition, Characteristics, and Applications of Refractory Mud, Refractory Cement, and Refractory Castables

1. Refractory Mud
Ingredients: Refractory mud is usually composed of refractory materials such as silicate or high alumina, binders, and other additives.

Features: Refractory mud has relatively good plasticity and is easy to construct. It is suitable for masonry, repair, and connection of small parts on the surface of high-temperature equipment. It can withstand higher temperatures but has a relatively low operating temperature range.

Application: Refractory mud is often used for repairing, patching, plugging leaks in high-temperature equipment, and building furnace walls, furnace roofs, and other parts.

2. Refractory Cement
Composition: Refractory cement is mainly composed of refractory stone, high alumina stone, and other primary materials and a certain proportion of binder.

Features: Refractory cement has high high temperature resistance and corrosion resistance. It is a structural refractory material, suitable for directly building the overall structure of high-temperature equipment, and has good compressive strength and stability.

Application: Refractory cement is often used to build the overall structure of furnace bodies, kilns, furnaces, and other high-temperature equipment, such as furnace walls, furnace bottoms, etc.

3. Refractory Castables
Composition: Refractory castables are composed of refractory aggregates, binders, and water-adding agents. The refractory aggregates can be high-aluminum aggregates or silicon carbide.

Features: Refractory castables are in a liquid or semi-fluid state and can be poured into high-temperature equipment by pouring, spraying, etc. It has good high-temperature and thermal shock resistance and is suitable for high-temperature equipment with complex shapes and internal structures.

Application: Refractory castables are often used for repairing, sealing, and masonry inside high-temperature equipment, such as masonry on the top, bottom, and back of the furnace wall.

In summary, refractory mud is suitable for repairing and connecting small parts, refractory cement is ideal for overall masonry structures, and refractory castables are suitable for pouring of complex shapes and internal structures. According to the specific usage requirements and equipment conditions, select appropriate refractory materials for application. Please note that the above information is for reference only. It is recommended to consult with professional refractory material manufacturers or technicians for further consultation when making actual selections.
