Castable Refractories
Refractory castables are made from refractory aggregate and powder, binders, additives, and water. It is a kind of monolithic refractories for direct construction, which can be directly vibrated, poured or pumped into the working layer. It has various types, such as low cement castables, ultra-low cement castables, self-flowing castables, etc.
1.High bonding strength
2.Low thermal conductivity
3.Good thermal shock resistance
4.Easy construction.
Castable Refractories Description
Refractory castables are made of refractory aggregate, powde and binding agent. The refractory castables are manufactured by mixing and molding according to the requirements of the casting process, and then dried and sintered at high temperature. Refractory castables are mainly used for lining and repairing of thermal equipment such as blast furnaces, hot blast stoves, and soaking furnaces.
The Application Of Castable Refractories
Refractory castables have the characteristics of low bulk density, good thermal shock resistance, good resistance to slag erosion and spalling, good wear resistance, and good heat insulation. It can ensure the safe operation of the incinerator, prolong the service life of the incinerator, and reduce maintenance and maintenance.
Refractory castables are used in non-ferrous metal smelting furnaces, including aluminum, copper and zinc, to provide insulation, lining protection and resistance to spalling. Refractory castables are commonly used for furnace roofs, walls and hearths, and sometimes for the lining of tapholes or chimneys.
Refractory castables are widely used in the petrochemical industry for lining furnaces, vessels and pipelines. Refractory castables have excellent heat and chemical resistance, making them suitable for extreme temperatures and oxidizing atmospheres. They are easy to install and can be customized to meet specific design requirements.

A1:Refractory castable is a pre–mixed, ready–to–use material made from refractory aggregates, cementitious binder and admixtures. It is used for the construction of monolithic linings for furnaces, kilns, incinerators and other high temperature applications.
A1:Refractory castables offer several advantages over other refractory materials. They are easy to install, require minimal maintenance, and can be customized to fit any shape or size. In addition, they can be used in a wider range of temperatures and are more resistant to thermal shock and erosion than other materials.
A3:Refractory castables are installed in a dry or wet form. In dry form, the material is mixed with water, troweled into shape, and then allowed to dry. In wet form, the material is mixed with water and then troweled into shape. Both methods require a 4–inch minimum thickness for furnace linings.
A4:All safety precautions should be taken when installing a refractory castable. It is important to wear gloves, safety goggles, and a respirator when handling the material. It is also important to ensure that there is adequate ventilation in the area to avoid breathing in dust particles.
A5:The curing process is important for any refractory castable. Depending on the type of castable, the curing process may vary. Generally, the castable should be allowed to dry slowly over a period of 24 to 48 hours or heated at a low temperature of 350°F over a period of time. It is important to follow the manufacturer’s instructions when curing the material.
