Difference between Castable Refractory and Refractory Castable

Castable refractory and refractory castable seem very similar in name, but there are obvious differences between the two in essence. Their main differences are mainly reflected in the composition, use, and construction process.

1. There are certain differences in the construction process between the two

Castable refractory mainly refers to pre-prepared refractory materials, such as castable prefabricated parts, prefabricated blocks, etc., which are customized in the early stage of construction and can be used directly after being pulled to the construction site, which can reduce the difficulty of construction and speed up the construction progress.

Refractory castable is a material that is mixed, stirred, and poured on site, and pays more attention to its pouring performance. It must usually be combined on-site with a forced mixer before use.

A material that is stirred with water before pouring construction.

2. The two are different in composition and use

Castable refractory is usually composed of various refractory materials and binders, suitable for lining and masonry of various high-temperature equipment, with high fire resistance and mechanical strength. Refractory castables are mainly composed of refractory particles and binders and are suitable for casting construction of various shapes, such as furnace walls, furnace roofs, etc.

From this, it can be seen that although castable refractory materials and refractory castables are very similar in name, the difference between the two is mainly reflected in the construction before and after. Castable refractory materials are mainly shaped before construction, while refractory castables are cast and shaped on-site.
