How to distinguish fire cement and furnace castable

Both fire cement and furnace castable are unshaped refractory materials used in high-temperature thermal equipment. Ακόμη, there are many differences between the two, which can be distinguished by the use, form, and construction method.

Refractory castables and refractory cement have different uses

Fire cement is mainly used to repair and bond refractory materials such as πυρίμαχα τούβλα and refractory boards to repair masonry structures or fill brick gaps. It is often used for repair and construction work in small areas. Refractory castables are mainly used for large-area refractory construction, such as casting refractory layers of kilns, furnaces, φούρνους θέρμανσης, and other equipment.

Refractory castables and fire cement have different shapes

Refractory cement is powdery, while refractory castables are composed of large and small particles and fine powder.

The construction methods of furnace castable and refractory cement are different

The refractory castable is constructed by vibrating pouring. Before construction, it is necessary to make the equipment pour the mixed castable into the construction area, and then discharge the air bubbles by vibrating to obtain a uniform construction effect. Refractory cement is generally used as an additive, not alone. It is used to evenly repair the construction site by smearing.
