About Fire Clay Bricks

Fire Clay Bricks

Offered Fire Clay Bricks are produced by using clay as their main raw material. Advanced mechanical extrusion molding technique is followed to produce such construction materials. These are heated under 900 degree C to 1000 degree C temperature range. Fire Clay Bricks are known for their wear resistance attributes, high mechanical strength, excellent high temperature creep rate and unique thermal shock resistance capacity. Volume stability of these bricks remains intact at high temperature. Application of these bricks can be noticed in machine processing, chemical, petroleum and also in metallurgy arena.

High Performance in Extreme Temperatures

Fire Clay Bricks are recognized for their outstanding ability to withstand continuous service temperatures between 1400C and 1500C. Their refractoriness under load (RUL) exceeds 1200C, ensuring they retain shape and integrity even in the most demanding industrial applications such as furnaces and kilns.

Precision Engineering and Customization

Available in the standard size of 230mm x 115mm x 75mm, and customizable for tailored projects, these bricks are manufactured to exacting standards. Uniform color, smooth finish, and consistent batch quality make them highly reliable for both small- and large-scale projects.

FAQs of Fire Clay Bricks:

Q: What are Fire Clay Bricks typically used for?

A: Fire Clay Bricks are commonly used for lining furnaces, kilns, incinerators, chimneys, and boilers in industries requiring excellent thermal resistance and durability. They serve as a protective layer, ensuring structural integrity during prolonged high-temperature operations.

Q: How do Fire Clay Bricks perform under continuous high temperatures?

A: These bricks offer remarkable performance at continuous operating temperatures up to 1400-1500C. Their excellent fire resistance (up to 1700C depending on composition) and high dimensional stability prevent distortion and degradation over time.

Q: What process is followed in manufacturing Fire Clay Bricks?

A: Fire Clay Bricks are produced by combining specific proportions of alumina and silica with other select minerals, shaping them into forms, and firing them at high temperatures. This process ensures optimal cold crushing strength, low porosity, and consistent color across batches.

Q: Where can these Fire Clay Bricks be installed?

A: They are suitable for a variety of high-temperature environments, including industrial furnaces, chimneys, industrial boilers, and kilns. Custom sizes and shapes are also available for unique installation requirements.

Q: What benefits do Fire Clay Bricks provide compared to other refractory materials?

A: These bricks offer a balance of durability, thermal stability, and chemical resistance, making them cost-effective and long-lasting solutions. High cold crushing strength and low moisture content also contribute to their structural reliability during prolonged use.

Q: How do I select the right grade or size of Fire Clay Bricks for my application?

A: Selection depends on your process temperature, chemical atmosphere, and physical requirements. Standard size is 230mm x 115mm x 75mm, but custom sizes and grades with variable alumina and silica content are available to match specific operational conditions.
