What is an example of a monolithic refractory?

An example of a monolithic refractory is castable refractory. Castable refractories are a type of refractory material that come in a powder form and are mixed with water or a liquid binder on-site to form a moldable and pourable mixture. This mixture can then be cast into various shapes, such as furnace linings, kiln linings, or other refractory structures.

Castable refractories offer several advantages, including ease of installation, versatility in shape and size, and good thermal insulation properties. They can be customized to suit specific application requirements by adjusting the composition and additives used during the mixing process.

Castable refractories consist of aggregates (such as high-temperature-resistant materials like alumina, magnesia, or silicon carbide), binders (like hydraulic cement or colloidal silica), and additives (such as plasticizers or deflocculants). The selection of these components determines the properties and performance of the castable refractory.

Due to their versatility and adaptability, castable refractories find applications in various industries, including steelmaking, aluminum processing, petrochemicals, incineration, and more.
