High Alumina Refractory Castable

Physical Parameters of High Aluminum Refractory Castables

Description of High Alumina Castables

The components of high-aluminum castables are high-purity high-alumina clinker, refractory clay and other binders in specific proportions. So, it is a type of monolithic refractory castable. Its alumina content is 50-80%.

This product has high flow properties when mixed with water and other liquids. It is cast and vibrated into shape. It can be processed into any shape required by industrial furnaces. In addition, it is a good material to make refractory prefabricated parts.

Advantages of High Aluminum Castables

• High-temperature resistance;
• High refractoriness;
• Good wear resistance;
• Strong thermal shock resistance;
• Strong chemical resistance;
• Low bulk density;
• Low porosity;
• High compressive strength.

Application of High Alumina Castable Refractory

High-aluminum castables are commonly used for prefabricated blocks lining equipment in the following industries:

• Steel industry: Ladles, hot blast furnaces, refining furnaces, heat treatment furnaces, blast furnaces, iron-making furnaces, etc.
• Petroleum industry: Catalytic reaction equipment, etc.
• Chemical industry: Tunnel kilns, crucible furnaces, incinerators, etc.
• Cement industry: Cement kiln, heating furnace, soaking furnace, rotary kiln, etc.
• Refractory industry: Refractory prefabricated blocks, etc.
• Electric power industry: Boilers, etc.

High Aluminum Castable Supplier

Often, you need more than a single high-aluminum castable. What you need more is experts who can make specific refractory material suggestions for your project. Therefore, you choose not only a supplier but also a highly professional and experienced manufacturer.

Manufacturers are usually better able to control product quality at the source. Moreover, they can provide customized products and quickly arrange production and delivery. Some trustworthy manufacturers also offer a wide range of kiln options.

Construction Method of High Alumina Castable Refractory

Step 1. Keep the construction surface clean and dry.
Step 2. Mix the raw materials evenly.
Step 3. The high-aluminum castable is poured and vibrated for compaction.
Step 4. Dry naturally or use equipment to air dry.

Precautions for Use

• Wear appropriate protective devices.
• Reasonably predict the solidification time of refractory castables.
• In different application scenarios, its materialization effects are different.
