Castable Refractories

Castable Refractories

Short Description:

Castable refractories are kind of granular and powdery materials made of refractory materials, and a certain amount of binder and moisture are added together. Castable refractories have high fluidity and is suitable for construction by casting method. It is an unshaped refractory that can be hardened without heating. The refractoriness is similar to that of refractory bricks of the same texture, the load softening point is slightly lower than that of refractory bricks, and the overall performance is better than refractory bricks. The castable has higher compressive strength at room temperature due to the effect of low temperature on the binder. Due to the good integrity of the masonry, the airtightness of the blast furnace is good, it is not easy to be deformed, and its resistance to machine vibration and impact is better than that of brick masonry.
