Differences and Applications of Refractory Mud, Refractory Cement, and Refractory Castables

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 high temperatures, but the use temperature range is relatively low.

Application: Refractory mud is often used for repairing, patching, plugging, and masonry of furnace walls, furnace tops, and other parts of high-temperature equipment.

Refractory cement

Ingredients: Refractory cement is mainly composed of materials such as refractory stone, high alumina stone, and a certain proportion of binders.

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

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

Refractory castables

Ingredients: Refractory castables are composed of refractory aggregates, binders, and water-adding agents, among which refractory aggregates can be high-aluminum aggregates or silicon carbide.

Features: Refractory castables are liquid or semi-fluid, and can be poured into high-temperature equipment by pouring, spraying, etc. It has good high-temperature resistance 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 the masonry of furnace tops, furnace bottoms, and the back of furnace walls.

In summary, refractory mud is suitable for repairing and connecting small parts, refractory cement is suitable for overall masonry structures, and refractory castables are suitable for casting complex shapes and internal structures. According to the specific use requirements and equipment conditions, select the appropriate refractory material for application. Please note that the above information is for reference only. It is recommended to consult with professional refractory manufacturers or technicians for actual selection.
