High Alumina Refractory Taper Brick 60 – 230×115×75/65 S/A

High Alumina Refractory Taper Brick 60 – 230×115×75/65 S/A is a specially shaped refractory brick manufactured from high-alumina refractory raw materials for high-temperature industrial applications. Designed with a tapered profile, this refractory brick is suitable for constructing, repairing, and maintaining circular, curved, and tapered refractory linings where accurate geometry and reliable thermal performance are essential.

With a nominal alumina content of approximately 60% Al₂O₃, this grade is engineered to provide a combination of high-temperature resistance, mechanical strength, abrasion resistance, and dimensional stability. Its tapered design, measuring approximately 230 × 115 × 75/65 mm, allows bricks to be arranged in curved or circular structures with reduced gaps and improved lining integrity.

High Alumina Refractory Taper Brick 60 is particularly suitable for industrial furnaces, kilns, boilers, chimneys, incinerators, heating chambers, and other thermal processing equipment where refractory lining is exposed to elevated temperatures and demanding operating conditions.


Product Overview

Refractory bricks are essential components in industrial thermal equipment because they protect structural surfaces from extreme heat, thermal shock, abrasion, and chemical attack.

The High Alumina Refractory Taper Brick 60 is designed for applications where conventional straight refractory bricks cannot provide the required curved or tapered geometry. Its specially engineered shape makes it easier to construct circular furnace walls, arches, linings, and other curved sections.

The tapered dimensions of 230 × 115 × 75/65 mm provide a gradual thickness variation that helps create the required radius when multiple bricks are installed together. This makes the brick particularly useful for circular and curved refractory construction.

Major Applications

1. Industrial Furnaces

High Alumina Taper Bricks are widely applicable in furnace lining systems where high temperatures and mechanical stresses are present. The tapered geometry makes them particularly useful in curved furnace sections.

They can be used in:

  • Industrial furnaces
  • Heating furnaces
  • Heat-treatment furnaces
  • Metallurgical furnaces
  • Process heating equipment

2. Kilns

The brick can be used in suitable curved or circular sections of industrial kilns. Its high-alumina composition provides improved resistance to heat and mechanical wear compared with many conventional fireclay refractory grades.

Potential applications include:

  • Rotary kiln components
  • Industrial kilns
  • Ceramic kilns
  • Lime-related thermal equipment
  • Process kilns

3. Boilers and Heating Systems

Refractory lining is required in selected high-temperature zones of boilers and heating systems to protect steel and other structural components from excessive heat.

High Alumina Refractory Taper Brick 60 can be considered for suitable areas where a shaped refractory lining is required.


4. Chimneys, Incinerators & Thermal Chambers

Special-shaped refractory bricks can be used for curved or circular sections of:

  • Industrial chimneys
  • Incinerators
  • Combustion chambers
  • Thermal processing chambers
  • Waste-treatment thermal systems

The final brick grade should be selected according to temperature, atmosphere, abrasion, chemical exposure, and design requirements.


Advantages of Taper Refractory Bricks

Better Curved-Lining Construction

The major advantage of a taper brick is its specially designed geometry. When multiple taper bricks are assembled correctly, they can form a circular or curved lining with better dimensional continuity.

Reduced Joint Gaps

Properly selected and installed taper bricks can help maintain more consistent joints in curved refractory structures. This contributes to improved lining integrity.

High-Temperature Performance

The high-alumina composition provides good refractory performance for demanding thermal applications, subject to the specific grade and operating conditions.

Mechanical Durability

High-alumina refractory products generally offer good mechanical performance, making them suitable for applications involving thermal and mechanical stresses.

Long-Service Potential

Correct material selection, installation, joint design, curing/drying, and controlled heating are all important factors in achieving long service life from refractory linings.


Installation Considerations

Correct installation is essential for obtaining maximum performance from High Alumina Refractory Taper Bricks.

Before installation, the supporting structure should be properly prepared and checked for dimensions, alignment, and stability. Bricks should be selected and arranged according to the required radius or lining design.

A suitable refractory mortar or approved joining material should be used according to the project specification. Joints should be maintained consistently, and unnecessary excessive mortar thickness should be avoided.

For circular construction, correct brick orientation and sequencing are particularly important. Improper arrangement can result in uneven joints, dimensional distortion, or localized stress within the lining.

After installation, the refractory lining should be properly dried and heated according to an appropriate dry-out and heat-up schedule. Rapid heating of newly installed refractory materials can cause steam pressure, cracking, spalling, or other damage.


Selection Criteria

Before purchasing or specifying High Alumina Refractory Taper Brick 60, the following factors should be considered:

🌡️ Operating temperature
🔥 Furnace or kiln atmosphere
⚙️ Mechanical loading
🛡️ Abrasion level
🧪 Chemical exposure
📐 Required lining radius
🧱 Required brick geometry
💧 Installation and drying conditions
🔧 Expected service life

Selecting the correct refractory grade according to the actual operating environment is essential for reliable performance.
