Strict Quality Control of Kerui Refractory Castable for Sale

Unlike traditional refractory bricks, castables offer superior installation flexibility, better thermal resistance, and longer service life.

Raw Material Preparation

Main raw materials include aggregates, binders, and additives. Aggregates include high alumina, tabular alumina, mullite, and silicon carbide. Select materials carefully and ensure stable quality.

Weighing and Batching

Screen the materials, weigh them accurately, and mix them by ratio. Use proper grading and control the mix to ensure good flow and compactness.

Production Process

Use a forced mixer and mix all materials evenly. Start with dry mixing, then add water and continue wet mixing until the mixture is uniform in the factory.

Packaging and Shaping

Pack the mixed material into bags for site use, or cast it in molds. Make precast blocks or lining modules inside the factory as needed.

Industrial Applications of Refractory Bricks

Refractories castable, refractory coatings, and refractory prefabricated components have extensive applications in many industries.

Using part: They are commonly used for lining high-temperature equipment such as furnace linings, furnace doors, chimneys, furnace covers, outlet pipes, wear repair areas, and insulation layers. Additionally, they are widely used in the construction of refractory structures.
